Wow, almost 1C hotter than prior El Niños 😵😣 Bracing for more heatwaves on land and sea, fires, coral reef bleaching, and flash floods to come. Resilience and adaptive capacity will be severely strained.

With all the July model runs now in, it is very likely that 2026 will see the largest El Niño event since records began in the late 1800s – and potentially by a truly mind-blowing margin. The median estimate is now 3.6C, roughly 0.8C hotter than the prior record (2.75C). www.theclimatebrink....

Did you know? Renewables have just overtaken coal as the world's largest source of electricity 34% – global renewable share, up 2x in 20yrs 48% – EU 37% – China 26% – US 24% – India

The world has warmed by around 1.4C since 1850. It took 148 years for the first half of that warming to occur, and just 27 years for the second half!

one of my favorite facts about the US coal industry is that it employs less people than Broadway

Another interesting fact: When I wrote that piece in 2019, 6,569 people in Kentucky, or 1 in 500 working age adults, were employed in coal mining. Today the number is 3,843, or about 1 in every 1,000 working age Kentuckians. But we have to save coal! Data here: eec.ky.gov/Energy/News-... 3/3

This message from IRENA DG / Report on Economics of 24/7 Renewables" needs to be on repeat everywhere: "The economics of the entire energy system have shifted…. advantage of renewables is not only economic but strategic, strengthening resilience, stability, and energy security in times of crisis.”

THREAD: The IEA global energy review 2026 * CO2 record high, but growth nearly ground to halt * Clean energy shaved 3bn tonnes off CO2 * Fossil-fuel power pushed into reverse * Age of Electricity "confirmed" * "Extraordinary" solar growth * Batteries up 40% * EVs up 20% 1/10

An economist friend passes along this graph of energy costs. He says, "Given this history, it is more than a little ironic that renewable energy is derided by fossil-fuel proponents as 'unreliable.'”

As I say here, there is no scientific justification to revoke the engagement finding. In fact, over the last 15+ yrs, the evidence of how climate change affects our health has only grown. Higher risk of allergies, dementia, fertility, heart disease, and death: that’s what’s on the line. @nature.org

There is No Scientific Justification to Revoke the Endangerment Finding

The U.S. EPA's decision to repeal the Endangerment Finding will limit the government's ability to regulate emissions of carbon dioxide and other greenhouse gases under the Clean Air Act.

In what is arguably the World's Best News, it looks like India is going to spend much less time in the "fossil fuel detour" than the US or China. It is moving much more directly to clean electrification. ember-energy.org/latest-insig...

I get that the news cycle is packed right now, but I just heard from a colleague at the Smithsonian that this is fully a GIANT SQUID BEING EATEN BY A SPERM WHALE and it’s possibly the first ever confirmed video according to a friend at NOAA 10 YEAR OLD ME IS LOSING HER MIND (a thread 🧵)

So spot on. And unfortunately similar to many of the DOE report responses

Kate Marvel@drkatemarvel.bsky.social · last yr.

Claim: "Water vapor is a greenhouse gas!" Reality: Yes, and there's more of it in a warmer atmosphere -"CO2 is plant food!" -pretty hard to eat when you're on fire -"Climate has changed before!" -We know, we told you that -"Scientists don't know everything!" - doesn't mean we know *nothing*

Our 400+ page comment on the DOE climate working group report is now out. Our conclusion: The merchants of doubt are back, and they're coming for climate science.

My ongoing request: If your NSF or NIH grant was terminated--whether at Harvard or elsewhere--please report it here. NSF: grant-watch.us/submit-nsf.h... NIH: grant-watch.us/submit-nih.h... Our trackers are actively used in lawsuits and are often the only record that terminations ever occurred.

Dan Garisto@dangaristo.bsky.social · last yr.

NSF appears to be terminating hundreds of its grants to Harvard, per internal sources at NSF and at Harvard. At least one division has had all its grants cut.

Yup. This was literally me. Funded by Nautilus Minerals to do baseline environmental impact assessment for a hydrothermal vent mine. Went in cautiously optimistic. Came out concluding there's no feasible path forward for mining a hydrothermal vent at any scale.

David Ho@davidho.bsky.social · last yr.

It's wild that all my colleagues who are funded by a deep sea mining company to research the topic ultimately conclude that we shouldn't mine the deep sea. We should stop seeing the ocean as a place to exploit instead of a place of wonder and beauty and an essential part of our life support system.
