Alright, we have reached the point in our climate dystopia that different hazards are fighting amongst one another.

There's something bizarrely Pyrocene about being thankful that high altitude wildfire smoke knocked temperatures down a few notches today during a heat wave in New England. Unfortunately, low altitude smoke still to come... www.cnn.com/2026/07/14/w...

Experts tell me there's increasing reasons to believe the ongoing El Niño event in the tropical Pacific could rival, if not break, historical records for its intensity. Here's what that would mean: www.cnn.com/2026/07/06/w...

Why do we have so many different ways to measure heat? Between the heat index and wet bulb globe temperature, what do each of these mean and when/why should we use them? www.cnn.com/2026/07/03/w...

Today has been another record breaking day, with a new provisional June temperature record of 37.3°C recorded at Santon Downham this afternoon

If the US government decides to allow a company to pollute by forgoing enforcement, DOJ argues in a recent legal filing that local communities can’t sue over the resulting pollution. Here's what you need to know (gift link): www.bloomberg.com/news/article...

After furious backlash on Capitol Hill and in the scientific community, the Trump Admin's NSF is reversing its decision to dismantle a sprawling ocean observing system. (Note: some damage has already been done, however.) www.cnn.com/2026/06/18/c...

NEWS: A bipartisan group of senators are seeking to triple the current size of NOAA’s aging Hurricane Hunter fleet, and codify NOAA’s weather recon role into law. www.cnn.com/2026/06/17/w...

"We can debate funding levels and priorities. What we cannot afford to risk is the momentum that those waiting for cures expect from us. If we walk away from that, we will not just lose the cures we have — we will lose the cures we have not yet imagined." www.statnews.com/2026/06/12/o...

Breaking: El Niño is officially here, and it could break records. NOAA is giving it a 63% chance of becoming one of the “largest El Niño events in the historical record going back to 1950.” www.cnn.com/2026/06/11/w...

Scientists are sounding the alarm about a new rule that would dramatically change how the federal gov't makes grant funding decisions. The rule is extraordinarily sweeping, and could have huge impacts on health and climate research. W/ @ellanilsen.bsky.social www.cnn.com/2026/06/04/c...

Climate change has put the oceans in deep trouble, and now the Trump admin is ditching a $368 million deep-sea monitoring system. www.cnn.com/2026/06/03/c...

BREAKING: A federal court has blocked the National Science Foundation (NSF) from transferring a major supercomputer away from the National Center for Atmospheric Research (NCAR) in Wyoming. This is good news! (🧵👇)

So, Reading University recorded 33.1°C today, which beats the previous all-UK May daily record. Kew Gardens says, “hold my beer”, recording 35.1°C. For the same weather patterns, these temperatures would have been low-30s in a past climate. Burning fossil fuels has made these heatwaves hotter.

Cannot 👏 emphasize 👏 this 👏 enough

A record-shattering heat wave is roasting Western Europe, spurred by a remarkably (record) strong heat dome for this time of year in that location. www.cnn.com/2026/05/26/c...

El Niño is poised to play a large role in the 2026 Atlantic Hurricane Season, with @noaa projecting that the odds favor a below average season. www.cnn.com/2026/05/21/w...

Add hurricane seasons to the growing list of phenomena (tornado seasons, extreme rains) that climate change is tending to “clump” into more extreme intervals punctuated by quieter periods. Weather and climate weirding, if you will.

We want to hear from you! The National Weather Service is planning to modernize its Cooperative Observer Program (COOP) network by harnessing new technology, optimizing observation sites and leveraging high-quality commercial data. Weigh in here: www.federalregister.gov/documents/20...

New from me for @cnn.com: "Climate change makes this El Niño a wild card, since it will occur in a far warmer world than that of 2015-16 and 1997-98 — and especially 1982-83." www.cnn.com/2026/05/19/c...

Psyched for the launch of the CNN Weather App, which I've been working on with a dream team of colleagues for months. It connects you with the experts & gives you a daily source of wonder. Here's the philosophy behind it: www.cnn.com/2026/05/12/w...

Together with my CNN Climate & Weather colleagues, I'm writing a newsletter (again!), this time a weekly on extreme weather and climate. It's free, and you can sign up here: www.cnn.com/newsletters/... Today's topic? The upcoming "Super" El Niño.

A Super El Niño is coming. Here's some of the likely impacts it could bring, from drought in Australia to a new hottest year record. www.cnn.com/2026/04/07/w...

The likelihood of a Super El Niño event this late summer/fall/winter have increased considerably. Here's what it could bring: www.cnn.com/2026/04/07/w...

“The fact that we’re melting out now, before we even have reached what historically has been the peak snow amount on the ground tells you everything you need to know,” CU Boulder's Jen Kay on the West's alarming wildfire risk. www.cnn.com/2026/03/27/w...

Prominent climate researcher Kate Marvel is leaving NASA, citing US attacks on Science www.bloomberg.com/news/article...

Emergency managers and meteorologists are about to lose access to a critical hurricane decision-making tool, known as HURREVAC, due to a lapsed contract. www.cnn.com/2026/03/24/w...

"The very fact that these reports feel too routine to cover is a testament to how far climate change has progressed, even just in the past decade. Unfortunately, we’ve built up some immunity to bad news about the climate." www.cnn.com/2026/03/23/c...

New analysis from me: UN climate assessment presents new info on Earth's growing energy imbalance thanks to record high amounts of climate pollution (chiefly CO2). www.cnn.com/2026/03/23/c...

New study finds the current heat wave in the West would be "virtually impossible" without human-caused climate pollution. We're on the verge of breaking an all-time March heat record for the US today/tmrw. www.cnn.com/2026/03/20/w...

"Meteorologists are reaching for superlatives to describe an oncoming heat wave so intense and rare for this time of year that it could leave some locations shattering their all-time temperature records for April before that month has even begun." www.cnn.com/2026/03/17/w...

NOAA issues an El Niño Watch, indicating conditions are favorable for it to develop during the next 6 months. More details (updated story), including info on its potential far-ranging impacts and intensity: www.cnn.com/2026/03/10/w...

Early signs of the formation of a potentially strong El Niño in the tropical Pacific have forecasters on edge. El Niño shifts weather patterns globally, increases global avg. temperatures and affects the Atlantic hurricane season. Stay tuned... www.cnn.com/2026/03/10/w... [NOAA img]

There are increasing signs that an El Niño, potentially an intense one, may develop in or by the Fall. This would cause global average temperatures to spike and shift global weather patterns. Uncertainty about such an event and its intensity is still significant, though. www.cnn.com/2026/03/10/w...

If you live in the eastern US like me you probably think this was one of the US' coldest winters on record. You'd be sorely mistaken. The record warmth out West overwhelmed the cold in the East during meteorological winter (Dec-Feb). www.cnn.com/2026/03/07/c...

My analysis of the fraught forecast for the ongoing blizzard, and the communications/public safety challenges it presented: www.cnn.com/2026/02/23/w...

"Rarely does such a powerful, blockbuster winter storm nearly sneak up on the most populous urban corridor in the US." www.cnn.com/2026/02/23/w...

Analysis: It's T-48 hours until a potential snowstorm along the Mid-Atlantic and Northeast coast, yet forecasters are struggling with some epic computer model disagreements. I take you behind the scenes to explain what's going on: www.cnn.com/2026/02/20/w...

Climate change has spurred scientists to come up with a new way of detecting and monitoring El Niño and La Niña, as the waters of the tropical Pacific rapidly warm. www.cnn.com/2026/02/17/w...
