I'm happy to share a paper in Science Advances that makes the case for a weak land carbon sink, drawing upon JPL and Chloris biomass time series. To close the budget with a net land sink of 0.8 Pg C/y from 2000-2019, we propose increases in the ocean sink and decreases in fossil fuel emissions.

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/...

If you want to get your simple climate model picked up by IPCC AR7, see below 👇 We have 11 on our radar from the previous round of RCMIP (egusphere.copernicus.org/preprints/20...), plus a few others we found since. Anybody we don't know about please ping me or Alex

Our finalised paper on flat10MIP is finally up in GMD! This is the experimental protocol which allows for a simple, emissions-driven evaluation of TCRE, ZEC and climate reversibility in CMIP7. Thanks so much to all who ran these simulations as a proof of concept! gmd.copernicus.org/articles/18/...

flat10-MIP has landed! gmd.copernicus.org/articles/18/...

very nice article by @afreedma.bsky.social at @cnn.com about our comment on the DOE report www.cnn.com/2025/09/02/c...

More coverage of the scathing review by more than 80 scientists of the report from the DOE's climate working group. It's biased, cherry picked, and written with a scientifically unsupported agenda. www.theguardian.com/us-news/2025...

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.

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.

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.

Great article in the NYTimes about our comment to the DOE about their climate report. Gift link: www.nytimes.com/2025/09/02/c...

To be clear, we really do not need to and should not be having to use our time 'debating' this fantastical nonsense in 2025. There are enough real bits of actual climate science to do. The collective brainpower expended on this by so many scientists could have been -much- better spent.

I helped write the responses to the DOE CWG report Chapter 9 (on Agriculture) and section 2.1 (on CO2 fertilization and greening). Several times I thought we should just use this post from @drkatemarvel.bsky.social as the whole response. bsky.app/profile/drka...

Reviewing this disinformation filled document was a colossal effort! See link in thread to sign up to receive the comment and press package.

Are you interested in biosphere-atmosphere interactions, global modeling, and living in Zurich? If so, this postdoc position might be for you! Please share with any interested colleagues: jobs.ethz.ch/job/view/JOP...

How long do you expect a journal to take to assign an editor?

They want to destroy OCO-2 and switch off OCO-3. As soon as October. 😤🤬😫

The @nationalacademies.org launches a fast-track review of latest evidence for whether greenhouse gas emissions endanger public health and welfare. The committee has issued a request for information with a submission deadline of August 27. www.nationalacademies.org/news/2025/08...

Fun fact: modern science is in fact aware of plants and how they work

🚨Job Alert🚨 We're hiring in the broad area of *Earth Surface Dynamics Geophysics* Please help me advertise this (rare) opportunity for a full-time tenure track assistant professorship. illinois.csod.com/ux/ats/caree...

Good article but I feel this also goes beyond the national angle. The decline in the scientific dominance of the US won't just hurt them, it could delay global scientific progress where other states don't have the drive, resources or concentrated expertise to carry on the momentum. /1

Sad to hear about the legendary Tom Lehrer passing. There was a period of time when we listed to a lot of his songs in our house! And a few of you may remember this: bantha-fodder.com/bootlegs/str...

Please consider joining our #AGU session on beautifully complex Water-Energy-Carbon interactions with a broad scope from theory to applied science. Invited talks by Julia Green @juliakgreen.bsky.social and Gabe Kooperman.

If you've been influenced or inspired by the contributions of Rafael Bras to hydrology and related fields please consider contributing to the Rafael L. Bras Symposium at the @ametsoc.org meeting in Houston next January. I'm very excited to see other Bras hydrology family members and friends there!

Is anyone planning on attending AGU this year? It seems like a tough year for making the decision this early…

Under Trump, NOAA ran the most recent competition for their highly prestigious postdoc program in climate and global change — but funded no one, wasting huge amounts of applicant and reviewer time. It gets a lot worse. Now current postdocs in the program are going unpaid.

This is such a loss. I've served on the selection committee for this program for the past three years, because it has funded so many incredible people doing such important research over the years. It should be expanding to meet the new challenges of climate change, but instead is totally defunded.

Do plants affect global climate through water? Some climate scientists say yes, but others say plants' effect is only local or regional. If the plant-power proponents are right, it means, to solve climate, we need more than the energy transition. We also need to restore land to health. My story:

Awesome new faculty job -- the University of British Columbia is looking for a senior ecosystem scientist to fill a new research chair position. geog.ubc.ca/job-opportun...

Looking for some more Earth system science in your next week? Check out the 30th anniversary CESM workshop! Land talks are Monday afternoon MT, and biogeochemistry is Tuesday morning. It's free to register for remote attendance: urldefense.com/v3/__https:/...

Great communication about the impacts of the sledgehammer the administration is taking to science in the USA in general and to NOAA in particular.

New #FATESmodel postdoc in Oslo! Come and join our team :) www.jobbnorge.no/en/available... Postdoctoral Research Fellow in terrestrial carbon cycle modelling (281332) | University of Oslo

I'm tearing up right now, that was incredible 😭😭 Thank you to everyone who turned up to share their science, and to our amazing team who pulled this all off in ≈6 weeks! Call your reps --> wclivestream.com/act Give feedback --> wclivestream.com/next Love you all ❤️

Don't miss the home stretch of talks! We have an AMAZING lineup for you all <3 including @zacklabe.com and @drshepherd2013.bsky.social ! wclivestream.com/schedule

The @wclivestream.bsky.social is going strong and almost to hour 80! I tuned in to find @lnzhang-climate.bsky.social hosting a solid set of talks about carbon cycling including from @biometlab.bsky.social and Gretchen Keppel-Aleks! Watch here: wclivestream.com

Thought-provoking quote from @atmostaj.bsky.social during the Weather and Climate Livestream about the role of "serendipity" in scientific discovery and the importance of having a broadly funded scientific enterprise that allows for it. wclivestream.com/watch/

Like so many climate scientists my career passed through GISS. I have formative memories of taking classes in the GISS conference room. Evicting them is senseless and a huge waste of time and money.

Last day at the GISS building (Wed. May 28th). 🥲

Make sure to catch the #SaveAmericasForecasts 💯 hour livestream! It's an inspiring collection of talks bringing attention to the need for federal funding for climate and weather research. For those of us in the field it's also comforting to hear familiar voices standing up in solidarity for science.

the scientific community is awesome, pass it on

I'm giving a virtual seminar on May 27th at 14:00UTC! Maybe I'll see some of you there?

I got to go to a science meeting this week. This felt extra special given the current massive uncertianty around funding for science and it reminded me that I still love doing science and talking about science! What we learn benefits society, as does training more people to think scientifically.

Reminder to NYC defenders of science, particularly climate science - NOON event up by Columbia in support of GISS, the NASA lab where @drjamesehansen.bsky.social did his keystone work in the 70s 80s and dozens of staff still do (until the end of the month).

From hundreds of terminated grants in biomedicine to selective prosecutions to organizational overhauls at the nation's science funding agencies, today's news reports salvo after salvo from a Republican administration dead set on destroying higher education—and with it, US leadership in technology.
