Updated: Fears and Facts about Reservoirs and Methane

Posted on by Ron Clutz

A previous post explained how methane has been hyped in support of climate alarmism/activism. Now we have an additional campaign to disparage hydropower because of methane emissions from dam reservoirs. File this under “They have no shame.” Excerpts below with my bolds.

On March 5, 2018 a study was published in Environmental Research Letters Greenhouse gas emissions of hydropower in the Mekong River Basin can exceed those of fossil fuel energy sources

“The hydropower related emissions started in the Mekong in mid-1960’s when the first large reservoir was built in Thailand, and the emissions increased considerably in early 2000’s when hydropower development became more intensive. Currently the emissions are estimated to be around 15 million tonnes of CO2e per year, which is more than total emissions of all sectors in Lao PDR in year 2013,” says Dr Timo Räsänen who led the study. The GHG emissions are expected to increase when more hydropower is built. However, if construction of new reservoirs is halted, the emissions will decline slowly in time.

Another recent example of the claim is from Asia Times Global hydropower boom will add to climate change

The study, published in BioScience, looked at the carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) emitted from 267 reservoirs across six continents. In total, the reservoirs studied have a surface area of more than 77,287 square kilometers (29,841 square miles). That’s equivalent to about a quarter of the surface area of all reservoirs in the world, which together cover 305,723 sq km – roughly the combined size of the United Kingdom and Ireland.

“The new study confirms that reservoirs are major emitters of methane, a particularly aggressive greenhouse gas,” said Kate Horner, Executive Director of International Rivers, adding that hydropower dams “can no longer be considered a clean and green source of electricity.”

In fact, methane’s effect is 86 times greater than that of CO2 when considered on this two-decade timescale. Importantly, the study found that methane is responsible for 90% of the global warming impact of reservoir emissions over 20 years.

Alarmists are Wrong about Hydropower

Now CH4 is proclaimed the primary culprit held against hydropower. As usual, there is a kernel of truth buried beneath this obsessive campaign: Flooding of biomass does result in decomposition accompanied by some release of CH4 and CO2. From HydroQuebec:  Greenhouse gas emissions and reservoirs

Impoundment of hydroelectric reservoirs induces decomposition of a small fraction of the flooded biomass (forests, peatlands and other soil types) and an increase in the aquatic wildlife and vegetation in the reservoir.

The result is higher greenhouse gas (GHG) emissions after impoundment, mainly CO2 (carbon dioxide) and a small amount of CH4 (methane).

However, these emissions are temporary and peak two to four years after the reservoir is filled.

During the ensuing decade, CO2 emissions gradually diminish and return to the levels given off by neighboring lakes and rivers.

Hydropower generation, on average, emits 50 times less GHGs than a natural gas generating station and about 70 times less than a coal-fired generating station.

The Facts about Tropical Reservoirs

Activists estimate Methane emissions from dams and reservoirs across the planet, including hydropower, are estimated to be significantly larger than previously thought, approximately equal to 1 gigaton per year.

Activists also claim that dams in boreal regions like Quebec are not the problem, but tropical reservoirs are a big threat to the climate. Contradicting that is an intensive study of Brazilian dams and reservoirs, Greenhouse Gas Emissions from Reservoirs: Studying the Issue in Brazil

The Itaipu Dam is a hydroelectric dam on the Paraná River located on the border between Brazil and Paraguay. The name “Itaipu” was taken from an isle that existed near the construction site. In the Guarani language, Itaipu means “the sound of a stone”. The American composer Philip Glass has also written a symphonic cantata named Itaipu, in honour of the structure.

Five Conclusions from Studying Brazilian Reservoirs

1) The budget approach is essential for a proper grasp of the processes going on in reservoirs. This approach involves taking into account the ways in which the system exchanged GHGs with the atmosphere before the reservoir was flooded. Older studies measured only the emissions of GHG from the reservoir surface or, more recently, from downstream de-gassing. But without the measurement of the inputs of carbon to the system, no conclusions can be drawn from surface measurements alone.

2) When you consider the total budgets, most reservoirs acted as sinks of carbon in the short run (our measurements covered one year in each reservoir). In other words, they received more carbon than they exported to the atmosphere and to downstream.

3) Smaller reservoirs are more efficient as carbon traps than the larger ones.

4) As for the GHG impact, in order to determine it, we should add the methane (CH4) emissions to the fraction of carbon dioxide (CO2) emissions which comes from the flooded biomass and organic carbon in the flooded (terrestrial) soil. The other CO2 emissions, arising from the respiration of aquatic organisms or from the decomposition of terrestrial detritus that flows into the reservoir (including domestic sewage), are not impacts of the reservoir. From this sum, we should deduct the amount of carbon that is stored in the sediment and which will be kept there for at least the life of the reservoir (usually more than 80 years). This “stored carbon” ranges from as little as 2 percent of the total carbon output to more than 25 percent, depending on the reservoirs.

5) When we assess the GHG impacts following the guidelines just described, all of FURNAS’s reservoirs have lower emissions than the cleanest European oil plant. The worst case – Manso, which was sampled only three years after the impoundment, and therefore in a time in which the contribution from the flooded biomass was still very significant – emitted about half as much carbon dioxide equivalents (CO2 eq) as the average oil plant from the United States (CO2 eq is a metric measure used to compare the emissions from various greenhouse gases based upon their global warming potential, GWP. CO2 eq for a gas is derived by multiplying the tons of the gas by the associated GWP.) We also observed a very good correlation between GHG emissions and the age of the reservoirs. The reservoirs older than 30 years had negligible emissions, and some of them had a net absorption of CO2eq.

 

Keeping Methane in Perspective

Over the last 30 years, CH4 in the atmosphere increased from 1.6 ppm to 1.8 ppm, compared to CO2, presently at 400 ppm. So all the dam building over 3 decades, along with all other land use was part of a miniscule increase of a microscopic gas, 200 times smaller than the trace gas, CO2.

Background Facts on Methane and Climate Change

The US Senate is considering an act to repeal with prejudice an Obama anti-methane regulation. The story from activist source Climate Central is
Senate Mulls ‘Kill Switch’ for Obama Methane Rule

The U.S. Senate is expected to vote soon on whether to use the Congressional Review Act to kill an Obama administration climate regulation that cuts methane emissions from oil and gas wells on federal land. The rule was designed to reduce oil and gas wells’ contribution to climate change and to stop energy companies from wasting natural gas.

The Congressional Review Act is rarely invoked. It was used this month to reverse a regulation for the first time in 16 years and it’s a particularly lethal way to kill a regulation as it would take an act of Congress to approve a similar regulation. Federal agencies cannot propose similar regulations on their own.

The Claim Against Methane

Now some Republican senators are hesitant to take this step because of claims like this one in the article:

Methane is 86 times more potent as a greenhouse gas than carbon dioxide over a period of 20 years and is a significant contributor to climate change. It warms the climate much more than other greenhouse gases over a period of decades before eventually losing its potency. Atmospheric carbon dioxide remains a potent greenhouse gas for thousands of years.

Essentially the journalist is saying: As afraid as you are about CO2, you should be 86 times more afraid of methane. Which also means, if CO2 is not a warming problem, your fear of methane is 86 times zero. The thousands of years claim is also bogus, but that is beside the point of this post, which is Methane.

IPCC Methane Scare

The article helpfully provides a link referring to Chapter 8 of IPCC AR5 report by Working Group 1 Anthropogenic and Natural Radiative Forcing.

The document is full of sophistry and creative accounting in order to produce as scary a number as possible. Table 8.7 provides the number for CH4 potency of 86 times that of CO2.  They note they were able to increase the Global Warming Potential (GWP) of CH4 by 20% over the estimate in AR4. The increase comes from adding in more indirect effects and feedbacks, as well as from increased concentration in the atmosphere.

In the details are some qualifying notes like these:

Uncertainties related to the climate–carbon feedback are large, comparable in magnitude to the strength of the feedback for a single gas.

For CH4 GWP we estimate an uncertainty of ±30% and ±40% for 20- and 100-year time horizons, respectively (for 5 to 95% uncertainty range).

 

Methane Facts from the Real World
From Sea Friends (here):

Methane is natural gas CH4 which burns cleanly to carbon dioxide and water. Methane is eagerly sought after as fuel for electric power plants because of its ease of transport and because it produces the least carbon dioxide for the most power. Also cars can be powered with compressed natural gas (CNG) for short distances.

In many countries CNG has been widely distributed as the main home heating fuel. As a consequence, methane has leaked to the atmosphere in large quantities, now firmly controlled. Grazing animals also produce methane in their complicated stomachs and methane escapes from rice paddies and peat bogs like the Siberian permafrost.

It is thought that methane is a very potent greenhouse gas because it absorbs some infrared wavelengths 7 times more effectively than CO2, molecule for molecule, and by weight even 20 times. As we have seen previously, this also means that within a distance of metres, its effect has saturated, and further transmission of heat occurs by convection and conduction rather than by radiation.

Note that when H20 is present in the lower troposphere, there are few photons left for CH4 to absorb:

Even if the IPCC radiative greenhouse theory were true, methane occurs only in minute quantities in air, 1.8ppm versus CO2 of 390ppm. By weight, CH4 is only 5.24Gt versus CO2 3140Gt (on this assumption). If it truly were twenty times more potent, it would amount to an equivalent of 105Gt CO2 or one thirtieth that of CO2. A doubling in methane would thus have no noticeable effect on world temperature.

However, the factor of 20 is entirely misleading because absorption is proportional to the number of molecules (=volume), so the factor of 7 (7.3) is correct and 20 is wrong. With this in mind, the perceived threat from methane becomes even less.

Further still, methane has been rising from 1.6ppm to 1.8ppm in 30 years (1980-2010), assuming that it has not stopped rising, this amounts to a doubling in 2-3 centuries. In other words, methane can never have any measurable effect on temperature, even if the IPCC radiative cooling theory were right.

Because only a small fraction in the rise of methane in air can be attributed to farm animals, it is ludicrous to worry about this aspect or to try to farm with smaller emissions of methane, or to tax it or to trade credits.

The fact that methane in air has been leveling off in the past two decades, even though we do not know why, implies that it plays absolutely no role as a greenhouse gas.

More information at THE METHANE MISCONCEPTIONS by Dr Wilson Flood (UK) here

Summary:

Natural Gas (75% methane) burns the cleanest with the least CO2 for the energy produced.

Leakage of methane is already addressed by efficiency improvements for its economic recovery, and will apparently be subject to even more regulations.

The atmosphere is a methane sink where the compound is oxidized through a series of reactions producing 1 CO2 and 2H20 after a few years.

GWP (Global Warming Potential) is CO2 equivalent heat trapping based on laboratory, not real world effects.

Any IR absorption by methane is limited by H2O absorbing in the same low energy LW bands.

There is no danger this century from natural or man-made methane emissions.

Conclusion

Senators and the public are being bamboozled by opaque scientific bafflegab. The plain truth is much different. The atmosphere is a methane sink in which CH4 is oxidized in the first few meters. The amount of CH4 available in the air is miniscule, even compared to the trace gas CO2, and it is not accelerating. Methane is the obvious choice to signal virtue on the climate issue since governmental actions will not make a bit of difference anyway, except perhaps to do some economic harm.

August Update: Pacific El Niño and Atlantic Niña Impacting Hurricanes

Posted on by Ron Clutz

A previous post in July reprinted below describes the unusual oceanic event juxtaposing a strong Pacific El Nino with an Atlantic Nina.  Now in August Colorado State University (CSU) hurricane researchers have maintained their forecast for a well  below-average Atlantic hurricane season with their updated 2026 projection.

Meteorology Science Behind These Forecasts

From severe-weather.eu: Above is the 30-day anomaly change, which shows the extent of cooling over the last month. You can see the cooling process over a large area of the tropical Atlantic, peaking right over the equatorial region, where the trade winds are strongest.

When observing changes between the ocean and the atmosphere, there is one indicator that tells us right away how the atmospheric circulation is behaving, called the Velocity Potential. This tells us on a large scale, where air is sinking and where it is rising in the atmosphere.

An example of this is shown in the image above: increased storms and rainfall on one side, and reduced storms and drier weather on the other. You can see on the top, how the air is diverging (moving away) and converging (moving together). This movement and rising/sinking of air is referred to as the Velocity Potential.

Above is the average upper-level velocity potential during a cold Atlantic Niña event in August. You can see sinking air over the Atlantic, aided by its cold Niña event, or at least by its driving force, while the Pacific is in strong lift mode (usually El Niño).

The main focus in these maps is an area called the Main Development Region (MDR). It is where tropical systems form and strengthen during the Hurricane Season, like a hurricane nursery area.

You can see this area marked in the next image below, which is the EMCWF seasonal forecast for the September 2026 Velocity Potential anomaly. This is the peak month for hurricane activity, and as you can see, the forecast shows a significant lift anomaly in the Pacific due to the Super El Niño Event.

Note: In this chart, the blue area signifies rising air, and the red area shows sinking air.

That creates a matching pair in a sinking air region to the west over the Indian Ocean, outlining large-scale atmospheric circulation. The Atlantic MDR zone is in a neutral anomaly, but with Africa suppressed, this is unfavorable for a large number of storms.

El Niño events also significantly alter the number of tropical systems in the Atlantic and their intensity. At the top is our simple schematic of the El Niño impact on the hurricane season, producing an atmospheric flow that causes a hostile environment for tropical storms, protecting the U.S. from landfalls.

There’s been much ado about a strong El Niño, but less is heard about the appearance of a sister anomaly Atlantic Niña.  What happens to summer storm activity when both are on stage?  Ben Cost does a good job of pulling together the implications in his NY Post article El Niño’s sister La Niña has arrived in the Atlantic — here’s what that means for summer weather.  Excerpts in italics with my bolds and added images.

Update with latest Ocean SST from OISST v.2

As described in more detail below, currently we are seeing an unusual mixed signal in the ocean patterns: a surging El Nino in the Pacific and at the same time an Atlantic Nina.  Here are the latest data from OISST v.2 regarding this phenomenon.

 

The extremely strong El Niño brewing in the South Pacific isn’t the only unusual weather pattern on the horizon.  Meteorological experts warn that the oceanic anomaly’s sister —  Atlantic Niña — could be rearing its head in the tropical part of The Pond, potentially helping curtail the number of storms we’ll see this season, according to Severe Weather Europe.

A map of global sea surface temperature anomalies on July 15, 2026, shows a significant region of below-average sea surface temperatures off the western coast of Africa.

This climate pattern is similar to La Niña — the cold phase of the El Niño Southern Oscillation (ENSO) — in that both cause temperature plunges below average. The difference is that this big chill affects the eastern equatorial Atlantic Ocean instead of the central and eastern equatorial Pacific, potentially altering wind and rainfall across the tropics, per Climate.org.

These two anomalies appear to work on opposite poles (warm vs. cold), but they are actually perfectly aligned in their atmospheric impact.

Should surface temps on the Atlantic Ocean hover at 0.9 degrees Fahrenheit below average for at least two overlapping seasons, this could mark just the sixth Atlantic Niña in the last four decades.

The sibling anomaly El Niño, meanwhile, causes preternaturally warm temperatures on the Pacific Ocean’s surface with forecasters predicting that this particular version could be up to 6.5 degrees warmer than average, potentially making it the strongest El Niño on record.

Despite being polar opposites on the thermometer, these temp-affecting twins are “perfectly aligned in their atmospheric impact,” long-range forecaster Andrej Flis wrote for Severe Weather Europe.

This means that both will help curb hurricanes — but in different ways. El Niño produces high wind shear and sinking dry conditions over the Atlantic and Caribbean — where wind shear is already the second highest on record for July — potentially nipping the storm systems in the bud, according to Weather.com.

This prophylactic effect is evident in the dramatic reduction in the number of forecasted storms, which currently totals just nine, according to Colorado State University’s tropical meteorology project team.

Of these, only four are projected to become hurricanes, while just one will attain Category 3 status or stronger, marking five fewer storms and three fewer hurricanes than an average season.

El Niño’s sister system, meanwhile, literally throws cold water on cyclones. Cooler ocean temps in the Atlantic prevent the heat and moisture buildup required for thunderstorm buildup, according to The Conversation.

It will be interesting if these sibling systems have double the preventive impact come hurricane season.

Despite the forecast covering the August-January period, we are already observing this in July. If we look at the seasonal forecast, the latest data clearly shows a large area of below-normal tropical activity across the MDR and the Atlantic region. At the same time, we see enhanced activity in the Pacific, aided by the low pressure and rising air associated with El Niño.

So far, Tropical Storm Arthur was the only named storm to form in the Atlantic Basin before July 17 — one fewer than during and average year, Gizmodo reported.

And while it caused flash flooding and tornadoes to lash the south, this so-called superstorm fizzled before long.   Meanwhile, there are no signs of an Atlantic hurricane; the first one usually forms by August 11.

Canada Wildfire Data vs. Fears

Posted on by Ron Clutz

Traffic moves along One World Trade Center in New York City amid smokey haze from wildfires in Canada.Andy Bao / AP June 2026

There’s been a lot of concern this summer about Canada wildfires along with claims about global warming/climate change being the cause.  This post is to provide data and history as context for understanding what happens in this boreal forest.  First an update from the Canadian Wildland Fire Information System (CWFIS).

The map shows the current distribution of wildfires in Canada and hotspots as of August 6, 2026. The Eastern part has now reduced down greatly.  The action now is in the West along the US border. The infographic provides the data on Active fires, new fires and extinguished fires. There are numbers for year to date and 10 yr. averages. The graph on the left shows area burned each year from 2017 through 2026 to date. Humans caused 42% of the number of wildfires, and nature caused 92% of the area burned.

As Chris Martz pointed out in an interview, boreal forests burn every year as part of their natural life cycle. Also Canada forests are vast and remote so that management is challenging.  A previous post here mentioned that some practices can and should be improved, especially since recent years have been more active and destructive, especially 2023, 25 and now 2026. Martz also provided some data contradicting the notion global warming is the cause.

The drought and heat wave indices are where climatic effects would show up.  Yes there are recent spikes, but also numerous precedents in the past. In neither case do the patterns reflect rising CO2, let alone human hydrocarbon use.  In fact there is a significant decrease in the worst of the drought categories despite the spike in 2023–24.

 

Climate Alarmists Gone?

Posted on by Ron Clutz

Transcript (with my bolds and added images)

Who is still panicking about climate catastrophe?

The Davos crowd? European Commission President Ursula von der Leyen didn’t mention the climate even once in her 2026 annual address—unlike in the past.

U.S. voters? Americans rank climate change at number 28 of 30 problems, and according to the Searchlight Institute, voters in battleground states are prioritizing pocketbook issues over climate.  

Canada? Prime Minister Mark Carney once championed radical climate policies but now wants to increase oil production.

The Europeans? After worrying intensely about climate change for a decade, they have other things to worry about: sky-high energy prices, low growth and the war in Ukraine. In their latest ranking, climate hit a new decade low.

How about global warming poster child Greta Thunberg? She has moved on to other causes.

Certainly, not people in poorer countries. They’re primarily concerned about the necessities of life — health, food and education. According to a recent survey of Africans, climate ranks near the bottom of their priorities, at number 31 of 34. That’s behind unemployment, the economy, health, education, poverty, roads, electricity, hunger, and corruption.

Even media outlets that once peddled climate alarm have backed off. According to a Washington Post analysis, 2025 saw the fewest media mentions of climate change in three years.

What led to this global change of mind? How could so many people
be so worried just a few years ago, and care so much less now?

First, everyone has started to realize that there are many other challenges in the world. 

After the end of the Cold War, people claimed that climate change was the last big challenge to fix. That was a common idea at Davos and among many global leaders. Now, everyone recognizes that climate change is just one of many issues: wars, budget deficits, immigration pressures, declining educational achievements, artificial intelligence, and demographic changes are just a few.

Second, you can only cry wolf so many times. 

How many “the end is nigh” predictions over the last 50 years?

One peer-reviewed study counted at least 78 specific claims, like when King Charles insisted that the world only had 18 months left to fix climate change. That was in 2019. So, that statement was wrong. And every statement by every well-known climate alarmist that has been resolved by 2026 turned out to be wrong. Not to mention when Al Gore told us in 2008 we only had 10 years left.

Third, climate policies are incredibly expensive and do little. 

The world has spent more than 16 trillion dollars to curb climate change, and governments are looking to spend hundreds of trillions more in the future.

A Science study of 1,500 climate policies in 41 countries across the last two decades showed that only 4% worked. In total, they cut less than a quarter of one percent of total emissions. If a private company had this kind of record, they’d be out of business.

Fourth, the alarmist claims are often blatantly misleading. When you’re told that sea level rise could force 187 million people to move, that claim unrealistically assumes nobody will do anything to address the problem for a century. But when people adapt — for example, by building levies — that number goes down 99.8%.

The Dutch solution to floods: live with water, don’t fight it. The same thing applies to climate change.

We’re constantly told more people will die from heat waves. But nobody ever reveals that the cold kills many more. Right now, warming temperatures actually save lives. And of course, when there’s cheap and reliable power, more people can afford air conditioning. As the US warmed in the 20th century, heat deaths declined significantly, exactly for that reason.

Climate economists have consistently shown that by the end of the century, climate change will cost 2-3% of global GDP. It is a real problem, but nowhere near Armageddon.

In fact, as the UN expects the average person to be 450% richer in 2100, climate change simply means it is going to feel like we’re ‘only’ 435% richer than now. That’s still a much better world — just not quite as good as it could have been.

We still need to fix climate change, but we can do so smarter. Don’t pour trillions into policies that don’t move the needle, but billions into green energy R&D. This will help develop cheap green energy alternatives that can eventually outcompete fossil fuels on price.

Ending the climate panic means our kids won’t be needlessly scared, and neither will we. Being frightened without reason doesn’t lead to smart policies.

Rather, we can start focusing more on the many other pressing problems we need to fix now. Putting the climate panic behind us makes that possible.

July 2026 SH Ocean Cools, Land Warms, Global UAH Stable

Posted on by Ron Clutz

The post below updates the UAH record of air temperatures over land and ocean. Each month and year exposes again the growing disconnect between the real world and the Zero Carbon zealots.  It is as though the anti-hydrocarbon band wagon hopes to drown out the data contradicting their justification for the Great Energy Transition.  Yes, there was warming from an El Nino buildup coincidental with North Atlantic warming, but no basis to blame it on CO2.

As an overview consider how recent rapid cooling  completely overcame the warming from the last 3 El Ninos (1998, 2010 and 2016).  The UAH record shows that the effects of the last one were gone as of April 2021, again in November 2021, and in February and June 2022  At year end 2022 and continuing into 2023 global temp anomaly matched or went lower than average since 1995, an ENSO neutral year. (UAH baseline is now 1991-2020). Then there was an usual El Nino warming spike of uncertain cause, unrelated to steadily rising CO2, and now dropping back toward normal values.

For reference I added an overlay of CO2 annual concentrations as measured at Mauna Loa.  While temperatures fluctuated up and down ending flat, CO2 went up steadily by ~66 ppm, an 18% increase.

Furthermore, going back to previous warmings prior to the satellite record shows that the entire rise of 0.8C since 1947 is due to oceanic, not human activity.

gmt-warming-events

The animation is an update of a previous analysis from Dr. Murry Salby.  These graphs use Hadcrut4 and include the 2016 El Nino warming event.  The exhibit shows since 1947 GMT warmed by 0.8 C, from 13.9 to 14.7, as estimated by Hadcrut4.  This resulted from three natural warming events involving ocean cycles. The most recent rise 2013-16 lifted temperatures by 0.2C.  Previously the 1997-98 El Nino produced a plateau increase of 0.4C.  Before that, a rise from 1977-81 added 0.2C to start the warming since 1947.

Importantly, the theory of human-caused global warming asserts that increasing CO2 in the atmosphere changes the baseline and causes systemic warming in our climate.  On the contrary, all of the warming since 1947 was episodic, coming from three brief events associated with oceanic cycles. And in 2024 we saw an amazing episode with a temperature spike driven by ocean air warming in all regions, along with rising NH land temperatures, now dropping well below its peak.

July 2026 UAH Temps: SH Ocean Cools, Offsets Land Warming banner-blog

With apologies to Paul Revere, this post is on the lookout for cooler weather with an eye on both the Land and the Sea.  While you heard a lot about 2020-21 temperatures matching 2016 as the highest ever, that spin ignores how fast the cooling set in.  The UAH data analyzed below shows that warming from the last El Nino had fully dissipated with chilly temperatures in all regions. After a warming blip in 2022, land and ocean temps dropped again with 2023 starting below the mean since 1995.  Spring and Summer 2023 saw a series of warmings, continuing into 2024 peaking in April, then cooling off to the present.

UAH has updated their TLT (temperatures in lower troposphere) dataset for July 2026. Due to one satellite drifting more than can be corrected, the dataset has been recalibrated and retitled as version 6.1 Graphs here contain this updated 6.1 data.  Posts on their reading of ocean air temps this month are ahead the update from HadSST4 I posted recently on May 2026 SSTs Cease Warming. These posts have a separate graph of land air temps because the comparisons and contrasts are interesting as we contemplate possible cooling in coming months and years.

Sometimes air temps over land diverge from ocean air changes. 2025 showed a sharp contrast between land and sea, first with ocean air temps falling in January recovering in February.  Then in November and December SH land temps spiked while ocean temps showed litle change. In February 2026 NH land temps doubled, from Dec. 0.53C up to 1.14C last month.  Despite SH land changing little, and Tropical land cooling, the Global land anomaly jumped up from 0.53 to 0.93C.  That reversed in March with both NH land and Global land anomaly back down to 0.63C. That cooling offset SH Ocean warming doubling from 0.19C to 0.38C. In May was a warming spike in Tropics and SH ocean air while NH ocean air was flat. At the same time, Land air temps warmed in Tropics and NH while dropping in SH.  The unusual end result for May was Global, Land and Ocean air temp anomalies all showing the same 0.53C. In June SH land dropped sharply along with some SH ocean cooling, pulling down Global anomalies. Now in July, SH ocean cooled offsetting Global land warming.

Note:  UAH has shifted their baseline from 1981-2010 to 1991-2020 beginning with January 2021.   v6.1 data was recalibrated also starting with 2021. In the charts below, the trends and fluctuations remain the same but the anomaly values changed with the baseline reference shift.

Presently sea surface temperatures (SST) are the best available indicator of heat content gained or lost from earth’s climate system.  Enthalpy is the thermodynamic term for total heat content in a system, and humidity differences in air parcels affect enthalpy.  Measuring water temperature directly avoids distorted impressions from air measurements.  In addition, ocean covers 71% of the planet surface and thus dominates surface temperature estimates.  Eventually we will likely have reliable means of recording water temperatures at depth.

Recently, Dr. Ole Humlum reported from his research that air temperatures lag 2-3 months behind changes in SST.  Thus cooling oceans portend cooling land air temperatures to follow.  He also observed that changes in CO2 atmospheric concentrations lag behind SST by 11-12 months.  This latter point is addressed in a previous post Who to Blame for Rising CO2?

After a change in priorities, updates are now exclusive to HadSST4.  For comparison we can also look at lower troposphere temperatures (TLT) from UAHv6.1 which are now posted for July 2026.  The temperature record is derived from microwave sounding units (MSU) on board satellites like the one pictured above. Recently there was a change in UAH processing of satellite drift corrections, including dropping one platform which can no longer be corrected. The graphs below are taken from the revised and current dataset.

The UAH dataset includes temperature results for air above the oceans, and thus should be most comparable to the SSTs. There is the additional feature that ocean air temps avoid Urban Heat Islands (UHI).  The graph below shows monthly anomalies for ocean air temps since January 2015.

After sharp cooling everywhere in January 2023, there was a remarkable spiking of Tropical ocean temps from -0.5C up to + 1.2C in January 2024.  The rise was matched by other regions in 2024, such that the Global anomaly peaked at 0.86C in April. Since then all regions have cooled down sharply to a low of 0.27C in January.  In February 2025, SH rose from 0.1C to 0.4C pulling the Global ocean air anomaly up to 0.47C, where it stayed in March and April. In May drops in NH and Tropics pulled the air temps over oceans down despite an uptick in SH. At 0.43C, ocean air temps were similar to May 2020, albeit with higher SH anomalies. In November/December all regions were cooler, led by a sharp drop in SH bringing the Global ocean anomaly down to 0.02C. In 2026, ocean warming was evident, with Tropics and SH pulling up Global ocean air temps despite little rise in NH ocean. Now in June and July that has reversed with SH cooling and pulling down the Global ocean anomaly, even despite tropical warming.

Land Air Temperatures Tracking in Seesaw Pattern

We sometimes overlook that in climate temperature records, while the oceans are measured directly with SSTs, land temps are measured only indirectly.  The land temperature records at surface stations sample air temps at 2 meters above ground.  UAH gives tlt anomalies for air over land separately from ocean air temps.  The graph updated for July is below.

Here we have fresh evidence of the greater volatility of the Land temperatures, along with extraordinary departures by SH land.  The seesaw pattern in Land temps is similar to ocean temps 2021-22, except that SH is the outlier, hitting bottom in January 2023. Then exceptionally SH goes from -0.6C up to 1.4C in September 2023 and 1.8C in  August 2024, with a large drop in between.  In November, SH and the Tropics pulled the Global Land anomaly further down despite a bump in NH land temps. February showed a sharp drop in NH land air temps from 1.07C down to 0.56C, pulling the Global land anomaly downward from 0.9C to 0.6C. Some ups and downs followed with returns close to February values in August.  A remarkable spike in October was completely reversed in November/December, along with NH dropping sharply bringing the Global Land anomaly down to 0.52C, half of its peak value of 1.17C 09/2024. In 2026 January and February Global land rebounded up to 1.14C, led by a NH warming spike. That NH spike was reversed in March and April back down to 0.43C.  In May the Global land anomaly went back up to 0.53C with all regions around that value. Then in June land temps in SH plunged nearly 0.6C down to 0.2C, pulling Global land anomaly down more than 0.1C. July saw Global land temps up again with warming in all regions.

The Bigger Picture UAH Global Since 1980

The chart shows monthly Global Land and Ocean anomalies starting 01/1980 to present.  The average monthly anomaly is -0.02 for this period of more than four decades.  The graph shows the 1998 El Nino after which the mean resumed, and again after the smaller 2010 event. The 2016 El Nino matched 1998 peak and in addition NH after effects lasted longer, followed by the NH warming 2019-20.   An upward bump in 2021 was reversed with temps having returned close to the mean as of 2/2022.  March and April brought warmer Global temps, later reversed

With the sharp drops in Nov., Dec. and January 2023 temps, there was no increase over 1980. Then in 2023 the buildup to the October/November peak exceeded the sharp April peak of the El Nino 1998 event. It also surpassed the February peak in 2016. In 2024 March and April took the Global anomaly to a new peak of 0.94C.  The cool down started with May dropping to 0.9C, later months declined steadily until  August Global Land and Ocean was down to 0.39C. then rose slightly to 0.53 in October, before dropping. to 0.3C in December.  By May 2026 the anomaly was back up to 0.53C, now holding at 0.48C in July.

The graph reminds of another chart showing the abrupt ejection of humid air from Hunga Tonga eruption.

TLTs include mixing above the oceans and probably some influence from nearby more volatile land temps.  Clearly NH and Global land temps have been dropping in a seesaw pattern, nearly 1C lower than the 2016 peak.  Since the ocean has 1000 times the heat capacity as the atmosphere, that cooling is a significant driving force.  TLT measures started the recent cooling later than SSTs from HadSST4, but are now showing the same pattern. Despite the three El Ninos, their warming had not persisted prior to 2023, and without them it would probably have cooled since 1995.  Of course, the future has not yet been written.

Canada Govt. Aids and Abets Forest Fires

Posted on by Ron Clutz

Traffic moves along One World Trade Center in New York City amid smokey haze from wildfires in Canada.Andy Bao / AP June 2026

Dr. Joseph Fournier explains the situation in his Daily Wire article Blame Canada’s Terrible Regulations For Wildfires Ruining America’s Summer.  Excerpts in italics with my bolds and added images.

It’s a perfect storm of the decline of local lumber industries
and the policies put in place to (mis)manage Canadian forests.

Americans often picture Canada as a vast northern forest — an endless expanse of pristine wilderness. But the truth is far more complex and increasingly relevant to U.S.–Canada policy debates. Eighty‑nine percent of Canada is Crown land, owned by federal or provincial governments. Yet only about 10–12% of that land receives detailed ecological monitoring.  This matters because U.S. trade policy, Canadian conservation policy, and federal herbicide permitting are now combining to reshape North America’s forests in ways few Americans recognize.

Over the past 20 years, Canada’s sawmill and pulp‑and‑paper sectors have entered a steep decline. Statistics Canada and industry reports show that mill closures have accelerated, especially in western Canada, where over 30% of softwood lumber capacity has disappeared. Employment has dropped sharply. Entire forestry towns have hollowed out.

And while multiple factors contribute — mountain pine beetle damage, wildfire losses, transportation bottlenecks — the most overlooked driver is the federal government’s long‑standing approval of spraying Roundup (glyphosate) herbicide across millions of hectares of Crown forests. For decades, glyphosate has been used to kill broadleaf species — birch, aspen, poplar — so that commercially valuable conifers can dominate.

But this practice has consequences. Roundup creates monoculture conifer stands, which are more resin‑rich and significantly more flammable than mixed‑species forests. Instead of diverse, moisture‑retaining ecosystems, Canada is producing vast tracts of single‑age, single‑species pine and spruce — exactly the kind of forests that burn explosively under extreme fire weather.

The result is a continental paradox: Policies meant to “manage” forests
have instead created more combustible landscapes,
contributing to the anomalous rise in total annual area burned.

The deterioration of Canada’s forests is also being accelerated by domestic policy. Rising carbon taxes on diesel and gasoline — critical fuels for logging, hauling, and mill operations — have increased costs across the supply chain. New layers of regulation slow approvals and reduce harvest flexibility. And when pulp mills close, sawmills lose buyers for residual chips and sawdust, further undermining their economics.

But the most consequential impact of this industrial contraction is ecological. Canada’s parklands — where monitoring exists — show a clear trend of rapidly aging boreal forests, with large stands now reaching 70 to 120 years old.

In Alberta’s eastern foothills, provincial parks contain dense, overmature, fuel‑loaded forests primed for high‑intensity wildfire. Decades of fire suppression, beetle kill, drought, and heavy recreational pressure have created extreme fire risk. As Parks Canada itself warns, “the reduction or exclusion of fire as a natural process … leads to increased risk of wildfires.”

The consequences are here. Alberta’s Jasper National Park recently nearly burned to the ground when extreme fire weather collided with decades of fuel accumulation, beetle‑killed forests, a highly vulnerable townsite, and infrastructure failures.

Nonetheless, long‑term fire data tell a more nuanced story.  According to Canada’s National Burned Area Composite and Canadian Interagency Forest Fire Centre wildfire statistics, forest‑fire frequency has declined since the 1980s. Canada is experiencing fewer fires overall.

What has changed is the total area burned, which had remained relatively moderate for decades but then spiked dramatically in 2023 and again in 2025, producing two of the worst years for fires in modern Canadian history.  These spikes reflect the dangerous combination of aging forests, heavy fuel loads, glyphosate‑driven monoculture, and extreme fire weather — not an increase in ignition frequency.

Meanwhile, federal biodiversity reports show that parks are not experiencing net improvement. Most ecosystems are stable, but among those changing, declines outnumber gains. And crucially, non‑park Crown lands are not monitored at all, meaning there is no empirical basis to claim that conservation designations improve biodiversity.

Yet Ottawa is moving ahead with its flagship 30×30 agenda — a plan
to place 30% of Canada’s land and water under conservation status by 2030.

In practice, this means restricting forestry across vast areas as forests age, become fuel‑loaded, and become increasingly prone to extreme fire behavior. By limiting private‑sector utilization, 30×30 will increase fuel loading, exacerbate forest aging, and reduce thinning and harvesting activities that mitigate catastrophic wildfire risk.

For Americans concerned about lumber prices or wildfire smoke drifting south, the lesson is simple. Canada’s forests are increasingly unmanaged, aging, and burning, not because Canadians don’t care, but because the economic and policy frameworks governing those forests are pushing the country toward less active management.

North America needs forestry — not just parks — to remain resilient.

2026 July Arctic Ice Extents Return to Mean

Posted on by Ron Clutz

Russian Nuclear Icebreakers on the Northern Sea Route, March 2025

The arctic ice extents are now reported through July 2026, and as noted previously the wavy polar vortex has hampered ice formation with incursions of warmer southern air into the Arctic circle.  This factor receded in May and June, with extents closing the gap with the averages. The Northern Sea Route (NSR) goes through the Russian shelf seas of Laptev, East Siberian, and Chukchi seas on the way to Bering Strait in Beaufort Sea.

As the image from July 31 shows, the Arctic Ocean core is still solid, while parts of the Eurasian NSR have open water on the left vertical side. Ice persists in Laptev (top left) and Chukchi (bottom Left).  As usual in July, Hudson Bay (bottom right) is full open water, as is Baffin Bay (middle right).  Canadian Archipelago retains considerable ice cover.

The chart below shows the 20-year July averages for Arctic ice extents, along with 2026, 2025 and 2007 as well as SII v.4. Note that on average during this period 2.7M km2 of ice extent is lost. MASIE tracked average throughout, slipping below mid month, before ending July with a slight surplus.  SII v.4 continues to underestimate Arctic ice extent, ending July 0.4M km2 in deficit to MASIE, and down 338k km2 for the July month average.

The table below shows the distibution of ice extents on day 212 across regions of the Arctic ocean.

The table shows that many regions are close to or above the 20-year average. The Eurasian shelf seas of Laptev, Chukchi and Beaufort are in surplus. The only sizeable deficits are Greenland Sea and Central Arctic. Bering and Okhotsk seas are left off the list since they are open water now as usual.

Decoding the Flailing Climate Alarm Story

Posted on by Ron Clutz

There have been various reports, including some reposted here, about the Climate Crisis narrative losing its grip on the public and leaders.  Signs the fad is waning include some advocates like Bill Gates recanting, ESG financiers like Larry Fink backtracking, falling media coverage and closure of some climate units, and the recent admission of implausible climate model scenarios.

Even so, there are still many in its thrall, and it’s important to understand how climate doomster culture took over and continues to demand attention and deference.  Garry Rogers provides a brief and insightful analysis of how this happened, and why its influence is rightfully dwindling.  His blog article is Why So Many People Fall For The Climate Crisis Narrative. Excerpts in italics with my bolds and some added images.

You’ve seen them. Earnest young activists shouting at clouds, gluing themselves to museum walls, and blocking traffic with coroplast signs warning that the world will end in twelve years unless we obey their vision of salvation—complete with windmills, solar panels, and vegan diets. They’re the same people Xing and Instagramming about carbon footprints from their iPhones made in Chinese factories run on sulphur and lignite coal-fired electricity.

It’s easy to dismiss them as naive or misguided, but the uncomfortable truth is this: many of these people are neither stupid nor insane. They are simply caught in a powerful psychological, cultural, and financial machine that has turned “climate change” into a form of religious belief—a doctrine too sacred to question and too profitable to abandon.

Let’s set something straight. I’m not a climate change denier. Climate change is real. The Earth’s climate has always changed. And it always will—human-contributed through emitted greenhouse gas or not.

But the apocalyptic narrative that dominates headlines, policy, and corporate strategy today isn’t just about facts. It’s about framing—about controlling how people think, feel, and act in relation to a deeply complex system they barely understand. And that makes the climate crisis one of the most successful psychological operations in modern history.

In this post, we’ll take a hard look at why so many people have bought in—blindly and without skepticism—to the idea that we’re on the brink of planetary collapse, and that the only solution is top-down control, mass compliance, and the destruction of energy systems that built the modern world.

Some of what I’m going to say may be uncomfortable to some, and I know some
will unsubscribe. But that doesn’t make it untrue, and this needs to be said.

The Climate Crisis as a Religion (aka The Church of Carbon)

First, let’s call it what it is. For a growing number of people—especially in the West (Europe particularly included)—the climate crisis has become a belief system. It functions just like a fundamentalist religion, complete with original sin (industrialization), prophets (Greta, Gore, Gates), sacred texts (IPCC reports), rituals (recycling, carbon offsets), heretics (climate skeptics), and a promised apocalypse for those who fail to convert.

It’s not about science anymore. It’s about meaning.  People—especially young people raised in secular cultures—are starving for purpose. They want to feel morally righteous, socially important, and part of a grand, redemptive story. The climate narrative offers all of that in a tidy, emotionally satisfying package. It turns ordinary people into saviors. It makes them matter.  You can’t underestimate how powerful that is.

Fear is the Fuel

The second driver is fear. For decades, we’ve been bombarded with doom-laden, global-warming headlines: ice caps melting, oceans rising, hurricanes and tornados worsening, apocalyptical flooding, forests burning, deserts parching… The messaging is relentless—and expertly crafted to trigger our limbic systems. When people are afraid, they don’t reason. They react.

This isn’t new. Back in the 1970s, experts warned of an imminent ice age. Then came acid rain. Then ozone depletion. Each time, the world was supposed to end unless we handed over more power to government, more money to NGOs, and more control to unelected technocrats.

It’s always the same pattern:

  1. Declare a crisis.
  2. Blame human behavior.
  3. Offer a sweeping solution that just happens to consolidate control.

The only difference now is scale. The climate crisis is global,
not regional. And the proposed solutions are systemic, not marginal.

 The Collapse of Critical Thinking

But fear alone doesn’t explain the blind belief. There’s another piece of the puzzle: the steady erosion of critical thinking. Schools no longer teach logic, debate, or how to evaluate competing hypotheses. Instead, they promote conformity, activism, and groupthink. You don’t learn how to think. You learn what to think.

By the time students hit university, the programming is complete. Professors reinforce the dogma. Campus culture punishes dissent. Climate change isn’t a topic for exploration—it’s a moral litmus test. Students who question it risk grades, reputation, or worse. Being cancelled.

So, they comply. They absorb. They repeat. And when they graduate into journalism, academia, NGOs, or politics, they carry that unexamined belief system with them—passing it on like gospel.

The Media Echo Chamber

The next layer is media. Legacy outlets like CNN, BBC, CBC, and the New York Times frame climate change in religious terms: “Climate emergency,” “existential threat,” “code red for humanity.” Any nuance is treated as heresy. Any questioning is framed as denialism.

Science itself has been rebranded. Instead of a method of inquiry, it’s now a set of conclusions—conveniently aligned with elite interests. The phrase “The science is settled” is a dead giveaway. No real scientist would ever say that.

Meanwhile, dissenting voices—many with serious credentials—are marginalized, shadowbanned, or censored outright. Their data doesn’t fit the narrative. Their views make people uncomfortable. So, they are erased.

And most people? They never notice.They assume if something was true, they’d hear about it. But when every channel is playing the same tune, they don’t realize they’re listening to a carefully curated soundtrack.

Social Conformity and Virtue Signaling 

But here’s the deeper truth.  Most people don’t believe the climate crisis because they’ve studied the data. They believe it because everyone else does. That’s the power of social conformity. Nobody wants to be the outlier—the one who raises their hand and asks the uncomfortable question.  Especially in a culture obsessed with virtue.  Believing in the climate crisis is a modern form of moral signaling. You drive a Tesla. You compost. You use a keep-cup. You care. You’re not like those backward Boomer-deniers who love oil and hate penguins.

  • You’re evolved
  • You’re ethical
  • You’re better

That’s what this has become—not a conversation about climate,
but a competition for social status.

And once belief becomes part of your identity, it becomes non-negotiable. Any challenge feels like a personal attack. Facts don’t matter. Feelings do.

Follow the Money

Now let’s talk about power.

The climate industry is worth trillions—yes, trillions of dollars. It’s the perfect grift: a never-ending crisis that justifies endless funding, regulation, and surveillance.

  • Governments rake in carbon taxes.
  • Universities secure research grants.
  • Corporations get ESG ratings and subsidies.
  • NGOs fundraise on fear.

It’s an entire ecosystem of incentives, none of which reward skepticism or moderation. And when that much money is on the table, the truth becomes secondary to the narrative.

Even energy companies play along. They don’t want to be regulated out of existence, so they slap green labels on their products and talk about “net zero” while quietly hedging their bets. It’s theater. Everyone’s pretending.   But the costs are real.

China’s Role in the Global Equation

While the West ties itself in knots trying to decarbonize, one country is playing a different game entirely: China

Beijing talks green, but burns black. Coal remains its dominant energy source, powering steel, manufacturing, and military growth at a staggering scale. As of 2024, China alone consumes over half the world’s coal supply—and shows no sign of slowing down.

They’re not stupid. While we argue over wind farms and carbon credits,
they build aircraft carriers, drones, and power grids.
While we teach kids to fear climate collapse,
they teach theirs to master engineering and geopolitics.

They make the solar panels we install. They mine the rare earths we need. They profit from the very policies we impose on ourselves.  And we call that progress.

Weaponized Guilt

So why don’t people wake up?

Because they’ve been trained to feel guilty. Every gas-guzzling SUV trip, every propane-grilled burger, every jet-fueled flight—is framed as a moral failing. You’re killing the planet. You’re harming future generations. You’re part of the problem. It’s exhausting, and it’s effective.

People internalize this guilt. They try to cleanse themselves through ritualistic consumption: reusable straws, oat milk, biodegradable trash bags, canvas totes at the farmer’s market. None of it makes an infatismal sub-fraction of a surface dent in global emissions—but it feels redemptive.

That’s the point. It’s not about fixing the planet. It’s about managing the soul.

The Useful Idiots

Now we come to the crux.

The term “useful idiot” originated in Soviet times. It referred to Western sympathizers who unknowingly supported the goals of a regime they didn’t understand. They weren’t evil—just naive, manipulated, and eager to be on the “right side of history.”

That’s where we are today. Millions of well-meaning people have been seduced by a narrative that exploits their fears, flatters their vanity, and blinds them to the larger game at play. They march, post, and protest—believing they’re saving the world, while unwittingly aiding those who want to dominate it.

They’re not villains. They’re pawns. And when you try to wake-the-wokes, they look at you like you’re the crazy one. Then they viscerally turn on you.

What’s At Stake

Here’s what’s really at stake. If we continue down this path, we don’t just risk economic collapse or energy poverty. We risk civilizational suicide. We are dismantling the very systems—energy, industry, sovereignty—that made the modern world possible.

And we’re doing it not for the planet, but for appearances.

Meanwhile, the nations that reject this ideology are gaining power, leverage, and independence. They’re not afraid to use fossil fuels while experimenting with futuristics. They’re not ashamed of their ambitions. And they’re not held hostage by narratives designed to make them feel guilty for existing.

They’re playing to win. We’re playing to look virtuous. That’s a losing hand.

So, what do we do?

First, stop apologizing. There is no shame in using energy. Civilization runs on it. Human flourishing depends on energy, regardless of how it’s generated. Without it, we return to darkness—literally and figuratively.

Second, think for yourself. Ask questions. Follow incentives. Trace the money.
Be skeptical of anything presented as a one-sided moral truth.

Third, reclaim courage. Don’t be afraid to speak the truth, even when it’s unpopular. Especially when it’s unpopular. History doesn’t remember those who went along to get along. It remembers those who stood up, pointed at the naked emperor, and said, “This is madness.”

And finally, understand this: We are not in a climate crisis. We are in a clarity crisis. Clarity—real, hard-won, human clarity—is the first step back to sanity.

The next time someone tells you the world is ending, ask who’s funding the message—and what they’re selling with it. Because if you look closely, you’ll find it’s not about saving the planet. It’s about controlling the people on the planet by getting them to fall for the climate crisis narrative.

Extreme Weather and Climate Change Dashboard (Pielke Jr.)

Posted on by Ron Clutz

Roger Pielke Jr. has created a monitor at his THB (The Honest Broker) blog applying scientific and statistical rigor to detection of US Extreme Weather and Climate Change.  All the details and methodology are provided in his blog post US Extreme Weather and Climate Change Dashboard.

Overview

The THB US Extreme Weather and Climate Change Dashboard follows the Intergovernmental Panel on Climate Change’s (IPCC) framework for detecting a change in climate in the context of internal variability. This dashboard tracks 32 variables associated with 7 types of extremes: heat waves, tornadoes, flooding, drought, winter storms, wildfire, and hurricanes. The site presents data for the full range of data judged to be of sufficient quality for trend analysis, and on each page for each phenomena, users can choose the time frame over which to observe the data. This is ongoing work in progress – Suggestions welcome!

Detecting a change in climate is not the same as spotting a trend in a time series — it’s demonstrating that a trend is unlikely to have arisen from natural internal variability by chance alone. Here that means two things:

♦  First, detecting a trend at IPCC’s stated example threshold of below 10% (via the nonparametric Mann-Kendall test).

♦  Second, because a long, low-noise record can show a statistically significant trend as a result of internal variability, this dashboard adds another check before identifying a detected change: the trend’s magnitude must also be a meaningful share (this site’s threshold: at least 25%) of the variable’s historical variability. A trend can be identified in a time series and still not count as a detected change here for that reason: flooding’s trend, for example, is statistically real (p=0.011) but is only about 4% of its typical week-to-week range, and not at all unexpected.

This combined standard — IPCC’s likelihood criterion plus this site’s
magnitude check on trends — is what “detected change” means.

Each tile above shows a variable’s reliable-trend-window data at a glance and its detected-change verdict — click through to that variable’s phenomenon page for the full interactive chart, an adjustable time window, PNG/CSV downloads, and alternative metrics. Full definitions and caveats are documented on the Methodology page. A side-by-side comparison of how IPCC AR6 has characterized each hazard, and how it compares to this site’s findings, can be found on the Detection & Attribution page.

Detection and Attribution

This dashboard focuses only on detection, following the IPCC’s own framework for detecting a change in climate. The IPCC’s definitions are below (Glossary, AR5/AR6/SR15, “Detection and Attribution”), and are applied throughout this site.

  • Climate: “The average weather, or more rigorously, the statistical description in terms of the mean and variability of relevant quantities over a period of time ranging from months to thousands or millions of years.”
  • Climate change: “A change in the state of the climate that can be identified (e.g., by using statistical tests) by changes in the mean and/or the variability of its properties, and that persists for an extended period, typically decades or longer.”
  • Detection: “The process of demonstrating that climate or a system affected by climate has changed in some defined statistical sense, without providing a reason for that change. An identified change is detected in observations if its likelihood of occurrence by chance due to internal variability alone is determined to be small, for example, <10%.”
  • Attribution: “The process of evaluating the relative contributions of multiple causal factors to a change or event with a formal assessment of confidence.” This dashboard performs detection only — it does not attempt attribution, which requires separate causal/model-based analysis this project hasn’t undertaken.
