Our paper on a new ice shelf basal melt parameterisation is out! tc.copernicus.org/articles/19/... Small-scale processes in the ocean drive ice shelf basal melt, and large-scale ocean models can’t resolve these processes. Therefore, models use melt parameterisations, but these can still be improved.

The #ISMIP7 ice-ocean Antarctic focus group is recruiting a 2.5 year postdoc on ice-shelf basal melting at Northumbria University, Newcastle, UK. A great way to develop international collaborations and contribute to the improvement of sea level projections! work4.northumbria.ac.uk#en/sites/CX_...

This gets at what I think is a fundamental problem with most well-intentioned, public minded SRM work — the governance requirements for ethical SRM would seem to be a subset of the governance requirements that would allow any plausible need for SRM to be avoided.

Just arriving here. Let the adventure begin. Expect: ice, climate science, quirky notes and insights.

I've always said this, but since last November, I've been pointing this out frequently in whatever venues to whatever audiences I can: "The planet NASA studies most is Earth."

There's a good essay in @science.org about the importance of free global access to climate and weather data. The atmosphere doesn't know about borders, so paywalls anywhere hurt predictions everywhere; even more so for those who can't pay www.science.org/doi/10.1126/...

Proud of MIT for rejecting the Trump administration's dangerous and counterproductive "compact". orgchart.mit.edu/letters/rega...

Universities are in a tough spot. On the one hand, universities that sign away their futures for the possibility of some short-term gains deserve nothing but contempt, ridicule, and reputational destruction. There is no other hand here.

Since returning to office, the Trump admin has cut lifesaving federal science programs, medical research &grants. The AAUP and AFT launched a campaign to halt these cuts and continue the longstanding bipartisan commitment to funding scientific research that saves & improves the lives of Americans.

NSF today released instructions for the next round of applicants to its Graduate Research Fellowship Program. A key group—second-year Ph.D. students—is no longer eligible, and students who are still able to apply will face an unusually narrow timeframe. https://scim.ag/3KlQkQk

The GRFP announcement from NSF cuts out an entire cohort of 2nd year students from consideration, without warning. This is so deeply unfair that it warrants a formal protest from the scientific community. If someone wants to work with me to craft an open letter and solicit signatures, LMK.

New: After a long wait, the GRFP solicitation is live! Deadlines have been extended to early November, so applicants have a bit over a month to submit. www.nsf.gov/funding/oppo...

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 🧵)

In 2009, the EPA found that greenhouse gasses endanger public health, and put in place measures to protect the environment. Now, Trump’s rolling back these protections, making us less safe, and devastating the environment. @houseseec.bsky.social and I are demanding he restore these protections.

Trump was 24 years old in 1970. Maybe he just hasn't stayed up to date with climate science in the 55 years since...

In a UN speech today, President Trump said that "all of these [climate] predictions were wrong". Back in 2019 I led a research effort to digitize old climate model projections and assess how well they did. Turns out they got future warming pretty spot on!

Sorry, but disagree with @hausfath.bsky.social here. You open Pandora's box, you ain't closing it again. We've already seen with Paris that well intentioned international agreements do not translate into physical reality and SRM governance is a much harder problem. Zero is the only safe level. /1

Would be nice to see the enthusiasm for SRM redirected toward methane abatement and urban heat island mitigation, neither of which are “magic bullets” like SRM, but both of which meaningfully complement the temporal and/or spatial scales of decarbonization benefits

How does one of the most insightful climate scientists, Ray Pierrehumbert, who literally wrote the textbook on the topic, not have more followers?

I like Adam's work, and wish the department the best, but if I were an early career person thinking of this position, I'd have to ask myself whether given how Columbia disgraced itself by caving in to Trump, there could be any reassurance Columbia would have my back if my climate work irritated him.

Tonight I’m going to tell you about a California bill called SB326, authored by Senator Josh Becker and cosponsored by Senators Laird and Stern. This bill is perhaps the most significant wildfire legislation to land on Governor Newsom’s desk this year. I hope he signs it.

Maybe the land carbon sink is weaker than we thought. Big implications: "A lower-than-expected land carbon sink would also imply that the land biosphere may be closer to transitioning from a net carbon sink to a net source than current models predict" Randerson et al. www.science.org/doi/10.1126/...

The Department of Energy hired five academics to raise doubts about climate change. 85+ climate experts (organized by @andrewdessler.com) reviewed their report. Our conclusion, detailed in 450 pages of analysis: it is biased, full of errors, and not fit to inform policy making.

Look at this graph. The share of national income going to the richest 10 percent was lowest (and share to lower 90 percent highest) when union membership was at its highest. As unions have weakened, inequality has widened. This is why we must build back union power.

Our comment on the DOE CWG report is done. It tips the scales at 439 pages, approx. 3x longer than the DOE report. This is related to Brandolini's law: The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it. Example: refuting one sentence.
