End April 2025, an Arctic sea ice maximum volume was reached of about 19,000 km³. The 2026 maximum may turn out to be even lower, about 18,000 km³. In years when Arctic sea ice melting between April and Sept is strong, some 18,000 km³ of sea ice disappears. arctic-news.blogspot.com/2026/04/doub...

Wind and solar alone are currently providing nearly two thirds of electricity generation in Great Britain.

There is now clear evidence that changes in the Earth's climate may be sudden rather than gradual.

Deep-diving robots help crack the mystery of Antarctica’s vanishing sea ice Ten years ago, Antarctica's sea ice suddenly and dramatically declined. Scientists now blame a "very violent release" of deep, pent-up heat.

Global warming is making the strongest hurricanes stronger » Yale Climate Connections Recent studies link human-caused warming to more powerful, more destructive storms worldwide.

Your 'moment of doom' for Apr. 16, 2026 ~ a hard wind

"... we now need a 'Category 6' rating for hurricanes with winds of 193 mph (311 km/h) or greater, because global warming is expected to cause significant increases in maximum potential intensity."

The first step in solving a problem is understanding what the problem is.

When it comes to climate change, it basically boils down to phasing out greenhouse gas emissions.

But what gases, exactly? And where do they come from?

Here's the latest data.

Critical Atlantic current significantly more likely to collapse than thought Scientists say finding is ‘very concerning’ as collapse would be catastrophic for Europe, Africa and the Americas

"Rahmstorf, who has studied the Amoc for 35 years, has said a collapse must be avoided 'at all costs'. 'I argued this when we thought the chance of an Amoc shutdown was maybe 5%, and even then we were saying that risk is too high, given the massive impacts. Now it looks like it’s more than 50%.'"

Line graph time series of 2026's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2025. 2026 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between March and May by looking at the decadal average line positions.

Monday ice update - #Arctic sea ice extent is currently the 3rd lowest on record (JAXA data)...

• about 480,000 km² below the 2010s mean
• about 800,000 km² below the 2000s mean
• about 1,260,000 km² below the 1990s mean
• about 1,830,000 km² below the 1980s mean

Time series of daily TMAX for each year in Sedan, KS from 1893 to 2026. The year 2026 is highlighted, showing extraordinary warmth.

In March, ten stations were so warm that they would not only beat their April record but would also beat or tie their record for the warmest day ever observed in May.

In Sedan, Kansas, the 100 °F (37.8 °C) on March 22, 2026 was two months before the previous earliest 100 °F.

Map of US weather stations from GHCN-D that during March 2026 set new records (or tied) for the warmest day ever observed in March.

In March 2026, at least 1008 weather stations in the USA set (or tied) their local record for the warmest day ever observed in March.

Of these, 229 recorded a new March record so extreme that it would also beat any previously observed day in April.

Time series plot of changes in March monthly average temperature in the Western USA from 1850 to 2026 for both Berkeley Earth and ERA5. March 2026 was an extreme outlier.

To begin, let's look at monthly mean temperature.

The March average temperature across the Western USA was about +11.6 °F (+6.4 °C) warmer than the mid-20th century average.

That's an absurd 3.6 °F (2.0 °C) higher than the previous record.

GFS map of temperature anomalies over the contiguous USA for March 21, 2026.

We need to talk a bit about how utterly absurd the March heatwave was in the USA.

This heatwave would have been impossible without a boost from climate change, but even with climate change it remains a deeply unlikely event.

A thread looking at some of the numbers.

Beast mode for Typhoon #Sinlaku in the West Pacific right now. It’s rapidly intensifying and may reach Cat 5 equivalent Sunday. It is forecast to pass close to - or perhaps over - the US Island of #Guam, on Monday, population 167,000. Home to important U.S. Air Force and Naval bases.

Time series showing Southwest U.S. maximum temperatures from 1895 to 2026, which is a long-term warming trend and record for 2026.

Sooooo, the Southwest U.S. was more than 5°F warmer than the previous March record high for maximum (daytime) temperatures.... 🫠

Seven countries now generate 100% of their electricity from renewable sources, proving the transition is not theoretical but already operational. The barrier is no longer technology, but political will, investment priorities, and the courage to move faster.

The fossil fuel industry is probably the biggest fraud apparatus in the history of mankind.

It should be joyous to take that machine down. #EEODayRI

Spoiler alert: nothing trickled down.

OFFICIAL from @noaa.gov today: March blew the cover off the record books here in the U.S.

❗️Average temperature: 9.4° ABOVE the 20th century normal
❗️First time ANY month exceeded 9°F above average
❗️This was the ALL-TIME WARMEST March in the 132-year record

A powerhouse El Niño event appears to be brewing for 2026-27 » Yale Climate Connections Triplet tropical cyclones astride the equator could help it develop.

Signs of a high-end El Niño in the making are piling up fast. The picture includes an unusual set of tropical cyclones over the western Pacific. More here from me and @drjeffmasters.bsky.social: @climateconnections.bsky.social

It's be a tale of two countries as far as season-to-date snowfall goes (through March). In the Contiguous U.S., the season-to-date snowfall is in last place since 1940-41. In Canada, the season-to-date snowfall is in first place since 1940-41. Which team would you rather be on?

New El Niño forecast just dropped and it’s a whopper! Maybe the strongest on record. The European model seasonal forecast shows record Aug-Oct tropical Pacific sea surface temperature warmth at 2-3°C above normal (~ +5°F) in the central-east Pacific. The record for Aug-Oct is +2.2°C in 2015… 1/

"20 yrs ago the world took a year to add 1 gigawatt of solar.
Now it takes just half a day.

Solar costs have fallen by around 90% over past decade, & as costs fall, installations accelerate.

Nowhere is this clearer than in China 🇨🇳. It now accounts for well over half of global solar installations"

Let's check in on the Nov-Mar "cool/cold" season. It was warm. Very, very warm. A staggering 47% of the Contiguous U.S. had their warmest Nov-Mar since 1940-41. This Nov-Mar broke the record from 2011-12 by just over 1F. 🔥🔥🔥

Each year nuclear adds only as much net global power capacity as renewables add every two days.

Higher carbon storage in primary than secondary boreal forests in Sweden Boreal forests provide considerable global land carbon storage and uptake, but they are being rapidly transformed to managed secondary forests, with poorly quantified implications for ecosystem carbon...

Including vegetation, dead wood, wood products, and soils, primary forests stored over 70% more carbon than secondary forests, a difference several times greater than previous estimates.
