It appears that the U.S. Environmental Protection Agency (EPA) has, within the past week, scrubbed a large amount of climate change content from its official website, as well as *removed human-caused warming* from the discussion on its "causes of climate change" page.

The doubling of the rate of global heating in recent decades has surprised the scientific community so needs to be better understood yet our capability to measure Earth's energy imbalance is at risk: doi.org/10.1029/2024...

Next Tuesday evening, we are delighted to have one of the most remarkable and inspiring scientists as our guest. If you've never heard Naomi Oreskes @naomioreskes.bsky.social (Harvard University) in person, this is your chance at ETH Zürich as part of the SPEED2ZERO Perspective series.

The US brain drain. Cutting science, innovation and education is an incredibly short-sighted strategy. The loss in competitiveness, innovation, leadership and economic value to society is large, long-lasting and almost certainly exceeds the short-term savings by far. www.nature.com/articles/d41...

What a project! A group students talking to climate scientists. It was a pleasure to be part of this and share my views on climate and the role of scientific information in society. Open access. link.springer.com/book/10.1007...

In 2018, @blkahn.bsky.social said that the warming stripes graphic 'belongs in a damn museum', even suggesting that it was 'fit for the Museum of Modern Art' (see gizmodo.com/this-climate...). Well... Later this month, they will appear in the Museum of Modern Art: press.moma.org/exhibition/p...

Essentially all inhabited places on the planet were warmer in 2024 than the recent baseline. Most of the ocean area too. About 1/3 of the planet experienced record high temperatures. We know why. And we know how to fix it. @copernicusecmwf.bsky.social climate.copernicus.eu/global-clima...

All surface temperature products for 2024 are now live. All show 2024 is the warmest year (very clearly). The estimates of the change since the pre-industrial (1850-1900) are more uncertain but range from 1.46 to 1.62ºC. It is therefore *likely* this was the first year that exceeded 1.5ºC.

Does public #trust in scientists suffer or grow when they #advocate for #climate policies? ✊ We tested this during the referendum on the #Swiss Climate Protection Law on 18 June 2023 – which was preceded by a statement by 252 scientists supporting the law 🗳️ Paper: iopscience.iop.org/article/10.1...

The Seven Stages of climate denial: 1. It's not real 2. It's not us 3. It's not that bad 4. We have time 5. It's too expensive to fix 6. Here's a fake solution 7. It's too late: you should have warned us earlier Trolls use all of these stages to deny reality of #climatechange on Ex-Twitter 🤣

An argument you might hear from your cranky uncle at Thanksgiving - "climate is changing because climate has always changed". This commits single cause fallacy, assuming natural causes when other factors (like human activity) also drive climate crankyuncle.com/cranky-uncle...

This paper is a very interesting deep dive into how accurate the global temperature (particularly in the ocean) were in the early 20th C.
