It’s official. The 252 MPH gust observed in Hurricane Melissa, moments before she made landfall in Jamaica, is the STRONGEST wind gust ever recorded by a Hurricane Hunter dropsonde on Earth. It is almost unreal how extreme this storm was.

Magaziner: How many US military veterans have you deported? Noem: Sir, we have not deported U.S. Citizens or military veterans. Magaziner: We are joined on zoom by a gentleman who is army combat veteran who was shot twice while serving our country in Panama in 1989. Earlier

ICE detained a Navajo man for 4 hours after he identified himself, offered his Tribal ID, Certificate of Indian Blood, and birth certificate. They told him he must be stealing someone’s identity and that they would “get his family next.” As he described it: “I was treated as if

Illustration of how persistent and near record warmth (relative) in the Arctic - and the Greenland-Canadian Tundra block - is suppressing the Polar Vortex South, and is responsible for the generational #cold event in #Florida and expected SE Coast #blizzard This pattern

While cold conditions in the U.S. have made headlines, Greenland and the Arctic have quietly had a remarkably mild winter for their standards. Near Kullorsuaq, Greenland, the temperature is estimated to be *26 degrees above-average* since Dec. 1, the planet's largest anomaly.

It’s all connected! The Kona low/ Flooding in Hawaii, Extreme Heat in the West, the Blizzard in the G Lakes and incoming cold in the East. It’s all due to a highly amp’d pattern.

Watch as the West’s history making heat dome acts as a behemoth block in the atmosphere, rerouting the clouds riding the jet stream up and over the top, while forcing air to sink downward underneath it’s immense dome, crushing clouds and heating & drying the surface. Not a cloud

This is cartoonish. A +21°F (+11.7°C) national anomaly over the 1991–2020 baseline is the kind of number you’d expect from a broken model run… not reality. Yet here we are. March 20th and the entire country looks like late May (or worse). Records falling coast to coast,

Remarkable. Another 160 March monthly records today and counting on the CoolWx site. That’s ~370 monthly records broken over (some multiple days) the last 3 days, and that’s only the observation sites which are processed on the CoolWx website, so it’s a big underestimate. Magenta

Never seen anything like this. 200+ monthly records set today alone! Every pink dot means a city set its new all-time highest March temperature! That’s around 570 new monthly records in the last 4 days. Some set multiple times. By far the most rogue #heatwave the US has

Because almost no one in the media seems remotely concerned about climate change I sometimes think I’m going mad. This is Tenerife tonight. The island is under a red alert. Climate change is increasing rainfall intensity across the world: fact.

As the first reanalysis data become available, I think I can say with a fairly high degree of confidence that the March 2026 heatwave will go down as the most anomalously extreme heat event ever observed at any time of year in the southwestern U.S.

ERA-5 data is in. March was indeed the warmest on record in the US. But what’s even more astonishing is the trend. Since 1940 March in the US has warmed 7.2°F (that’s like 9° per century and accelerating!) Do the math on what this means for future generations if it continues. The

AMOC is weakening. New Potsdam Institute study: once it collapses, it stays collapsed. The point of no return was 350ppm CO₂. We crossed that in 1988. We're at 430 today. Without the Gulf Stream: US East Coast winters get extreme. Europe loses 7°C. Southern Ocean releases 83

I attended classes taught by the Godfather of Climate Science at Columbia. The fact that he nailed the warming “exactly” 45 years prior should be a pretty iron clad signal that climate scientists know what the heck they are doing and the science is incredibly solid. Putting all

A heat humdinger! Besides model agreement about the upcoming El Nino being strong or "super" - another clue is observing it as it takes shape in real time. Watch from late Feb to now as the subsurface heat - with anomalies in the +8C range now - roll across the Equatorial Pacific
