Excited to share our new publication in GRL We examine how a seasonal North Atlantic Oscillation affects the thermal and biogeochemical states in the North Atlantic Ocean for many years. agupubs.onlinelibrary.wiley.com/doi/10.1029/... @agu.org @ricliv.bsky.social

COP30 overpromised, underdelivered, empowered distractions, backtracked on issues and once again gave big oil and big ag a free pass. Unfortunately, the suspicions of climate scientists (here in Brazil and abroad) were confirmed again.

Science fraud is on the rise, facilitated by for-profit, open-access journals (Richardson et al, 2025, PNAS). These same journals are accelerating author and reviewer burnout by profiting from quantity while neglecting quality. Choose society journals where reputation and community are everything!

New data modelling suggests that the world is on track to warm by 2°C and 3°C even if countries met every near-term climate pledge and hit their targets for net-zero CO₂ emissions

Record warm ocean temperatures continued in September across the North Pacific Ocean, with a number of consequential impacts (including on downstream weather patterns). This graph shows the average for a band across the midlatitudes for every September from 1854-2025 using @noaa.gov ERSSTv5 data.

Two stories juxtaposed on the BBC website... sigh. Anyone else spot the irony here?

I guess I was right to switch to @bsky.app from Twitter. www.theguardian.com/technology/2...

Heavy monsoon rains trigger flash floods across Pakistan and India, forcing mass evacuations and causing deaths.

@metoffice.gov.uk ‘s 'State of the UK Climate' report is out today, with some key findings: 🌊UK sea level is rising faster than the global average 🌡️extremes are becoming the norm 🥇record breaking weather events are becoming more frequent 🔥the last 3 yrs have been in the UK's top 5 warmest on record

The Secretary of Commerce's new policy requiring his personal review of all NOAA contracts over $100,000 is directly harming American science. 🧪 How do I know? Because this morning, twelve of America's rising leaders in climate science (including myself) were furloughed.

What a tragedy this is even being proposed on paper... 💔 NOAA FY2026 Congressional Justification: www.noaa.gov/sites/defaul...

Excellent post by @dinahvp.bsky.social‬ on the plan to devastate NOAA research, with quotes from @franklinjamesl.bsky.social @wxmanms1.bsky.social. "Only a small fraction of NOAA Research would remain and be transferred to the NWS, including portions of the weather, tornado and technology research."

Awful. More horrible science news "The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) learned yesterday that the Department of Defense (DoD) will stop processing & delivering the Special Sensor Microwave Imager/Sounder (SSMIS) data no later than 30 June 2025."

I know there’s a lot of news right now but this is really crazy. They’re booting the National Science Foundation out of its newish building with no plans for where 1800 people are going to go.

Great initiative by Bill Gates. The global economic uncertainty and wars are hitting poor countries the most. Hope this initiative would provide the required investment.

Excited to share new research in the Journal of Geophysical Research:Oceans with @andyhogg.bsky.social, @navidcy.bsky.social, Ryan Holmes, and @hemant-khatri.bsky.social on how the North Atlantic Oscillation impacts the basin's subtropical and subpolar gyres: doi.org/10.1029/2024... 🌊

Trump just revoked the ability for foreign students to enroll at Harvard. Every foreign student, which is in the thousands, enrolled for next year at Harvard will not be able to continue studying if this isn't challenged in court. www.nytimes.com/2025/05/22/u...

RIP American science: NSF faces radical shake-up as officials abolish its 37 divisions, layoff staff, and terminate more funded grants.

Interesting study showing economic losses due to emissions by individual fossil fuel companies. Such studies aimed at quantifying economic losses and emissions by individual sectors, companies and countries are needed to determine accountability for global warming. www.nature.com/articles/s41...

"The possible elimination of the lab, called GFDL, in concert with potential cuts to other NOAA operations, threatens irreparable harm not only to global understanding of climate change and long-range scenarios for the planet but to the country’s safety, competitiveness and national security."

That's definitely on my reading list.

Looks like Trump has vowed to destroy everything, including oceans, climate research, trade, freedom of speech.

"To envision the disastrous impact of this plan, one only needs to see what NOAA research has provided to the U.S. taxpayer and imagine where we would be without it." "Now is the time to reach out to your elected representatives." "Stand Up for NOAA Research" - @nwas.org and @ametsoc.org statement

That's insane.

It's even worse than removing the grant funding for university research (in groups like mine at UC Irvine). NOAA labs and cooperative institutes collect the climate data we use, develop the predictive weather and climate models, and train the students we hire. This demolishes U.S. climate research.

Critical yet often overlooked is that NOAA's Oceanic and Atmospheric Research maintains vital long-term monitoring programs like the CO₂ Keeling Curve that, while essential, often struggle for funding from agencies like NSF that prioritize hypothesis-driven research over sustained observation.

It's sad to see CIMES funding cut at Princeton. It has been an incredibly successful research program.

What troubles me about Columbia, an institution I was associated with for 34 years, is that the actions of the Trump administration serve as a test case for future pressure on other universities, many of which lack the resources to fight. Things are gonna suck for academia in the US.

This won't end well.

It may be the time for Tesla to find a new CEO.

It would be good if there was a government agency tasked with warning people about these things.

Suppression of climate data built up by decades of hard working scientists dedicated to measuring and understanding planetary health. Removing facilities that measure climate change will not change US exposure to its catastrophic consequences 🔥🌀🌊🌪️

At least the UK is headed in the right direction.

“EPA head says he’ll roll back dozens of environmental regulations, including rules on climate change” by @matthewdalyap.bsky.social for @apnews.com: apnews.com/article/trum...

This is really sad news. NOAA GFDL is one of the world's leading climate modeling centers, home to exceptional scientists. If anyone directly affected needs support, I’m happy to help. www.science.org/content/arti...

While all of this is happening to our scientific agencies, the current extent of sea ice globally remains at record low levels... More visuals at zacklabe.com/global-sea-i...

The dismantling of NOAA is the dismantling of the United States www.axios.com/2025/03/03/d...

Can't stress enough how bad this situation is.

Trump and Elon just began firing hundreds of NOAA workers serving “mission-critical and life-saving roles.” These climate experts and forecasters are crucial to tracking natural disasters like hurricanes. Make no mistake, their terminations will cause preventable deaths.

One of the people fired from NOAA today is the director of the Ocean Acidification Program. That program also leads the U.S. government's effort on marine carbon dioxide removal (mCDR). The destruction of American science is incomprehensible.

It is sad to see years of research and progress being attacked and undermined.
