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

A fresh hell to consider.

Pretty extraordinary that the U.S. is experiencing its worst March drought on record, worse even than the Dust Bowl years of the 1930s. Drought is the most dangerous threat of climate change.

See the magenta in the middle of the map? That’s alert level 4 of 5 for bleaching in the #Galapagos. Common in El Niño where cool water upwelling slows/ stops and surface waters significantly warm. The sea surface temp anomaly is +3-4°C (~6°F). That’s why life suffers there every El Niño

The remarkable life of Super Typhoon Sinlaku.

Typhoon #Sinlaku has made a direct landfall on the Northern Mariana Islands (Saipan & Tinian); a US territory. While the storm weakened from its peak intensity (180 mph; 1-min avg; Category 5), it still struck as a powerful Category 4-equivalent storm.

1-minute @noaa.gov #GOESEast (GOES-19) Visible images with time-matched plots of SPC Storm Reports showed thunderstorms that produced tornadoes & large hail (up to 3.25" in diameter) & damaging winds (up to 88 mph) across southern Wisconsin, far NE Iowa & far SE Minnesota.

Severe and tornadic storms erupt across Iowa and Wisconsin.

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

As the Northern Mariana Islands take stock of the devastation left by Typhoon #Sinlaku, its worth taking a look at the latest research linking global warming to stronger hurricanes: yaleclimateconnections.org/2026/04/glob...

Why the Ridge Keeps Coming Back: The Structural Shift Behind Western Heat Domes Part 2: The leading mode of North American winter circulation has changed, and March 2026 is what the new mode produces In Part 1, I described the diabatic engine behind March 2026’s record-s…

Deirdre Des Jardins: Ridge amplification was driven by upstream heat from condensation in an atmospheric river attached to Hawaii's Kona low. "A warmer atmosphere holds more moisture. This means more water vapor is available for latent heat release in the cyclones driving ridge amplification."

Denver hit 80° for the 8th time this month. Not only is that more than double the previous March record for 80°+ days on record (3), it equals the *April* record for most 80°+ days on record (1987).

This absurd 'winter' keeps out absurding itself.

As I've said before, this is going to be perhaps the best movie with a meteorologist of all-time.

Graph of snow water equivalent in the state of Colorado for 2026 relative to climatological statistics since the 1980s. 2026 is current a record low around peak conditions typically in March and April.

Awful. Conditions just continue to worsen for Colorado's snowpack (and across many other western U.S. states), with average snow water equivalent nosediving after the historic March heatwave. (which actually continues today with more record heat!)

For your consideration: Crowd funding for "The Sky is the Limit (NCAR--A documentary about a crown jewel of American science, the National Center for Atmospheric Research (NCAR) and the peril it faces."

Colorado will have its lowest statewide peak snowpack on record (8.4″ SWE), which has likely already peaked due to our incoming heatwave. Official records date to 1987.

These paltry numbers below will likely plunge this week and next weekend.

Pick your weather poison this week: Tornadoes, blizzard, record rain, wildfire, or summerlike heat » Yale Climate Connections When you get a wildly contorted jet stream on a human-warmed planet, expect wild results.

It's March Madness, U.S. weather-style! @bhensonweather.bsky.social and I have the latest on the current Great Lakes blizzard, record Nebraska wildfires, Mid-Atlantic tornado threat, Hawaii record rains, and the mind-boggling Southwest U.S. heat wave:

It was da bomb.

A graph of US oil consumption and production by year since 1973. Consumption has steadily increased throughout. The US has doubled our oil production since Obama's "all of the above" energy strategy in 2009

The US is the reason this crisis exists, not just because of our reckless military, but also because our role in growing fossil fuel dependency.

In 2024 we consumed the most oil in one year of any country in history - roughly equal to the amount that passes through the Strait of Hormuz each day.

Heads up #Boulder: Stock up on water and batteries, charge your phones and eat your ice cream today

"Eat your ice cream," is the best advice I've ever been given.

February 2026 Colorado Monthly Climate Summary statewide departure from 1901-2000 avg: +9.2°F statewide departure from 1991-2020 avg: +7.6°F statewide rank: 1st warmest/132nd coldest Warmest February on record statewide Snowpack remains lowest in over 40 years Several locations, including Denver, Fort Collins, Akron, and Colorado Springs shatter records for most 60°F+ days Multiple grass fires, including ones near Boulder, Thornton, Matheson, and Wiggins Maximum daily precipitation (1.8" at Spud Mountain) Minimum daily temperature (-27°F in Taylor Park) Maximum daily temperature (85°F in Pueblo and Campo) Maximum daily snowfall 12.5" near Bayfield) February 2026 Temperature Rank (from NCEI nclimgrid) Statewide Temperature and Precipitation Ranks for February 2026 (based on 1895-2026 data) 1st warmest (record warmest) 37th driest (below average)

Unfortunately, not much good news to share in our February state climate summary. According to NOAA data, it was the warmest February in 132 years of records. Mountain snowpack remains at the lowest level in over 40 years. Several locations set new monthly high temperature records for February. 1/4

Ah! Love this!

Six trillion ways to solve climate change » Yale Climate Connections New research shows that mixing and matching manageable climate policy 'wedges' can add up to real solutions.

A new paper on the "stabilization wedge" idea was published in the journal Science today. The authors provide 36 wedge strategies that together can be mixed and matched into more than 6 trillion combinations able to limit global warming to 1.5°C. @bhensonweather.bsky.social has a detailed analysis:
