Speakers will identify how AI can be utilized to enhance weather and climate simulations and models, highlight the overarching technical challenges associated with integrating AI, and explore the most promising applications.

Happening tomorrow: National Academies webinar on AI for Emulation: Weather & Earth Systems Modeling, 10:00 ET. www.nationalacademies.org/event/45650_...

Yeah this is confusing for liberals ... We want fun control but not like this!

Ignoring the harmful effects of climate change will also affect national security.

I'm sorry to hear this

Having spent much actual and emotional time and energy responding to this report, I whole-heartedly agree. Greenhouse gas emissions are bad for our planet, it's not a matter for debate.

Good things are happening today - the side entrance to my building is open again, so I no longer have to carry my bike up stairs and through the main entrance. It's the little things.

Cool side fact: Working Group 1 assesses the physical science of climate change. The US has 15 authors in WG1, 10 of whom are women. In the last report, 6/25 US scientists in WG1 were women. Woop Woop 💪🏼, although it's a shame to see the reduced # of US scientists involved this time around. End 🧵

Because the US State Dept is no longer supporting American involvement in the IPCC, @agu.org and the US Academic Alliance stepped up to nominate 282 experts, from which 37 were selected. (A few more were nominated by other means.) Thanks guys! 🙏🏼

In this time of attacks on climate science in the US, it's important to point out that the IPCC does not set policy, but it provides scientific assessments that form one part of decision making.

This will be my first time participating as a lead author. I've been fascinated by the work of the IPCC and its role in informing climate policy for years, and inspired by those who have served before, so this is a huge honor for me.

I'm excited to contribute to the next IPCC report as a lead author for the WG1 chapter on "Global projections of Earth system responses across scales". We'll be assessing forcings of climate change and the responses across the Earth systems, including my favorite component 🥁... the carbon cycle.

The recent DOE climate science report misrepresents the work of many researchers. Carbon Brief asked those cited to review the parts of the report where their work was used, and we collectively found 100+ misleading or false statements: interactive.carbonbr...

I went for a run on my own at 6:15am and felt perfectly safe the whole time.

Erm, make that a *refutation* 🙄

I'd like to know more about a collective reputation of the report, as mentioned in this article.

Sure, this is completely normal ...

Scientists Say New Government Climate Report Twists Their Work A new Department of Energy report “fundamentally misrepresents” climate research and leaves out key context, multiple scientists cited in the report tell WIRED.

Just one example of the misrepresentations in the report, I've seen many similar reports www.wired.com/story/scient...

It's a great day to speak out against misinformation and lies designed to weaken climate regulation - follow the prompts below to enter your public comment on the EPA's proposed ditching of the Endangerment Finding.

Hi Neil, I've been thinking of looking at climate patterns for Georgia in my data science class, is the code you use for these graphs something you could share? My Exeter email address still works if so and you don't mind.

Analysis: The US government has declared war on the very idea of climate change | CNN Politics Americans are used to whiplash in their climate policy. The US has been in and out and in and out again of the key Paris climate agreement over the past four presidencies.

“In his second administration, President Donald Trump is not just approaching climate science with skepticism. Instead, his administration is moving to destroy the methods by which his or any future administration can respond to climate change.“

RealClimate: Spencer’s Shenanigans RealClimate: A recent sensible-sounding piece by Roy Spencer for the Heritage foundation is full of misrepresentations. Let's play spot the fallacy.

A few quick takes:

- the 'critical review' features a number of pretty standard and rebunked tropes.
- Spencer's 2024 (un-peer-reviewed) report for Heritage features strongly - and that was a hot mess of picked cherries: www.realclimate.org/index.php/ar...

The NYT article on this says it will be open to public comments, I'm sure they don't give a damn what a bunch of scientists say though. "After the proposal is published in the Federal Register, the E.P.A. will solicit comments from the public for 45 days, Mr. Zeldin said."

----- "Humans cannot possibly change the weather through greenhouse gas emissions causing climate change, that’s blasphemous"

Oh by the way and those same people ---- "Humans are changing the weather with weather machines, cloud seeding, and magical weather fairies with help from the groundhog"

😞

Looks like we were at the same conference this week. The sea gulls in Exeter are serious, I've had a whole sandwich nabbed right out of my hands!

The White House Gutted Science Funding. Now It Wants to ‘Correct’ Research.

🔔Trump’s Fool’s Gold EO is facing MAJOR backlash.

THOUSANDS of scientists, academics, & physicians - including us - are speaking out against this political assault on science.

My favorite dataset. For 65 years, it has recorded the seasonal breathing of the Earth due to photosynthesis & respiration, the steady rise of CO2 from burning fossil fuels, and year-to-year changes from factors like El Nino. Losing it & other atmospheric monitoring would handicap future discovery.

(I'm grateful to AGU for providing the opportunity for us to send nominations that won't just go into the void.)
