Revised estimates of CO2 sources and sinks improve global carbon accounting Updated estimates of the worldwide sources and sinks of anthropogenic carbon dioxide provide a firmer basis for monitoring climate action.

I am happy to share my @nature.com News & Views summarizing the recent adjustments to the Global Carbon Budget www.nature.com/articles/d41...

The Virtual Institute for the Carbon Cycle (VICC) - Schmidt Sciences

Thrilled to announce I'll be co-leading with Adrienne Sutton of @noaa.gov
a new project to observe carbon in the Southern Ocean winter using autonomous platforms: Constraining Ocean Carbon with Optimized Observing (COCO2). Grateful to Schmidt Sciences for the support!

The Ocean Carbon Sink Is Ailing Measurements analyzed by an international research team indicate the global ocean absorbed significantly less CO₂ than anticipated during the unprecedented marine heatwave in 2023.

news.climate.columbia.edu/2025/09/04/t... We've had a new analysis published on the impact on the ocean carbon sink from the unprecedented ocean warming of 2023.

Thank you to @ametsoc.org for this clear and compelling statement that illustrates the fundamental flaws in the recent DOE climate report www.ametsoc.org/ams/about-am...

5 forecasts early climate models got right – the evidence is all around you From rising global temperatures to the fast-warming Arctic, early climate models predicted the changes half a century ago.

Nice discussion here from Nadir Jeevanjee about the critical predictions that have endured from the earliest climate models

Our inevitable future, how do we balance perceived property and use rights as sea level rises? Such important questions with which we all need to engage.

NOAA’s Climate Website May Soon Shut Down - Eos Climate.gov, NOAA’s portal to the work of their Climate Program Office, will likely soon shut down as most of the staff charged with maintaining it were fired on 31 May.

NOAA’s Climate Website May Soon Shut Down eos.org/research-and... Not unexpected, but certainly unacceptable. US citizens and officials need reliable climate information.

Thanks @lamont.columbia.edu for the mention here. I am looking forward to this event on June 30.

Trump’s NIH And NSF Cuts Estimated To Cost The U.S. Economy $10 Billion Annually Economists find public R&D drives U.S. productivity growth — and pays for itself

www.forbes.com/sites/johndr... The economic benefits of research and the threats to the economy from proposed cuts are an important part of the story.

Choosing Our Future Thoughts on US federal support for science

Some thoughts from me on the current US administration's disastrous plans for science and technology funding.. It is time for everyone to speak up and ask for the investments that we need! galenmckinley.github.io/commentary/C...

NOAA will stop updating database tracking costliest weather disasters The billion-dollar disaster tracker is on a growing list of datasets NOAA says that either scientists will no longer update or the administration will decommission entirely.

When state support for science fails | Science www.science.org/doi/10.1126/... Science strengthens society and grows economies. US citizens and lawmakers should heed the warning of this article, and note China's major STEM investments. The US should be increasing federal investment in science!

@petebuttigieg.bsky.social I respect your track record and vision. I am an ocean and climate scientist and professor at Columbia U. What should I be doing to promote the value of science to red voters? Bluesky is nice, but an echo chamber. Fox isn’t going to interview me! what steps do you suggest?

Excited to attend the @nationalacademies.org 26th Roger Revelle Lecture ft. Dr. Chris Scholin of @mbarinews.bsky.social! This lecture will explore how robotics are revolutionizing oceanography in a changing climate.

Opinion | America’s Brightest Minds Will Walk Away (Gift Article) Young researchers are choosing between staying in science and staying in the United States.

www.nytimes.com/2025/04/03/o... The only way to have a strong country for the long term is to invest in new knowledge and, most importantly, the people who discover. The US is shooting itself in the foot right now

Columbia has many low income students and the most veterans of any ivy. Columbia is not the same as a public, but it doesn’t mean we sniff and survive. Your tone is sadly divisive when what we need is to STICK TOGETHER. Divided we cannot fight back to preserve education, research, and this country.

US-trained SpaceX and Tesla employees all went to institutions supported by federal grants, many likely with federal financial aid. If they did research, that was probably on federal support. The human capacity that drives these companies is federally funded. We have to get the word out on this!

Thanks to the folks at the ISTerre Lab in Grenoble for this show of support.

I am so sad to hear this news. Matt Eisaman will be missed.
