Seabirds are running out of ocean. Unlike many marine animals, seabirds don’t reduce body mass to survive climate change, they’re forced to disperse farther as their habitats disappear. By 2100, over 70% of species could lose huge parts of their range. www.nature.com/articles/s41...

Hi everyone, in the course of NorESM development for CMIP7 - we've had need to do some rapid benchmarking and diagnostics. To this end, I've made a couple of tools which might be useful for the wider community - python ports of ncview and CMAT. /thread/

📣 PRESS RELEASE IPCC expert authors are meeting this week in Santiago, Chile (21–24 April) to advance the first draft of the Working Group I contribution to the Seventh Assessment Report — covering the physical science of climate change. 🔗 lnkd.in/gAvBXeZf

Regardless of the US government’s position, US scientists continue contributing in full force to the @ipcc.bsky.social Seventh Assessment Report. Working Group 1 Lead Author Meeting, Santiago de Chile

Tremendous work behind us and and more so ahead. #IPCC_AR7 #Santiago_de_Chile

And LAM 2 is a wrap. *So* nice to be working closely w/smart, kind colleagues from around the world toward the common goal of science-informed policy. Lots of work to do between now and July to prepare the first order draft of the physical science report, then to meet again in Arusha in November.

One of my former students took her final project for my field natural history class and turned it into her Honors thesis: a 100% original, hand-drawn field guide to the rocky intertidal! And she got copies printed for her defense!

In a new Nature study, we show that extreme global climate outcomes may occur even under moderate 2°C warming for several sectors. The findings reinforce the urgency of limiting warming well below 2°C. Together with @erichfischer.bsky.social @janasillmann.bsky.social @zscheischlerjak.bsky.social

Climate has almost disappeared from our conversation. But it remains the most pressing challenge of our times. Last week the WMO said the planet is “more out of balance than at any time in observed history.” Energy security and climate security are not competing priorities.

ICYMI, some good news from @science.org: NASA has revived its next-generation satellite missions, which will study changing clouds and rainfall and use hyperspectral imagery to chart ecosystems, critical minerals, and greenhouse gases. These are big climate missions, even if NASA can't say that.

Trump is trying to shut down one of the world's premier climate & weather research labs. Why? A petty beef with a Colorado official who didn't support his effort to steal the election. That's it.

The good thing about jetlag is I have a whole new timeline to acquanit myself with! Nice to meet you folks.

Honestly, this historic heat dome across the West is really hard to put into words for me. Temperatures over 110°F (43°C) in March, shattering all-time monthly records on multiple consecutive days, and not just by a little. ➡️ I can confirm this is human-caused climate change. polarwx.com/models/

This is the hall where the Kyoto Protocol was signed. It’s impossible not to feel the weight of history and the juxtaposition to current anti-science sentiment. Last week’s CMIP meeting lived up to that legacy—well-organized & rigorous. Perfect blend of historic significance and vision. #CMIP2026

A nice example of the high scientific standard of the IPCC when it comes to downplay the warming Complex Earth system models are needed to simulate all these feedback's now becoming operational #climate #IPCC #CMIP

Have you noticed synchronized SST anomalies between the Pacific and Atlantic in global maps? It’s not a coincidence. According to a new study in Science Advances by Joh et al. (2026), this "oceanic handshake" is directly linked to the retreat of Arctic sea ice. 🌊🧪 ocean2climate.org/2026/03/01/t...

There are big fascists and there are small fascists. You don’t see the latter. They hide behind the big fascists. But they can inflict as much damage.

This is very promising new from the NASA administrator after Congress, in a bipartisan manner, restored deep cuts proposed by the WH. NOAA and NSF budgets were also mostly restored. Checks and balances still have a faint pulse... spacepolicyonline.com/news/isaacma...

While I am delighted to see this work published after collaborating with some of the field's greatest scientists, I am deeply unsettled by the consequences a potential AMOC collapse would have on communities and ecosystems. Here is to hoping global leaders take note. pub.norden.org/temanord2026...
