DOE climate report response form We are collecting names to assemble a writing team to respond to the DOE climate working group report. If you'd like to contribute, enter your info below. At this point, there is no guarantee what we'll do (if anything), but we want to keep our options open by collecting names. If you have any further questions, feel free to email me. We are primarily looking for Ph.D. scientists at universities or government labs in appropriate fields. I realize that this will exclude some qualified people and I apologize, but we felt this was necessary for a variety of reasons.

🚨 If you're interested in working on a coordinated response to the DOE climate report, please enter your info on this google form 🚨

Please RT this so as many people see it as possible.

Influence of Indian Summer Monsoon on Marine Biological Productivity Across the Late Pliocene and Early Pleistocene Indian Summer Monsoon runoff and marine productivity reconstructions from the Bay of Bengal in the Late Pliocene-Early Pleistocene Nuanced responses to eccentricity, obliquity, and precession cha...

🚨New paper alert🚨

We present the first record of Indian Monsoon variability and marine productivity spanning the late Pliocene–early Pleistocene (3.5 - 2.3 Ma).

Multi-proxy data from the core zone of ISM rainfall - the NW Bay of Bengal.

🧪 CRITICAL UPDATE: The House draft version is now out.

✅ Like the Senate's version, there's no cut to NASA's budget.

❌ There's a 23% proposed cut to NSF's budget.

Cold-air outbreaks in the continental US: Connections with stratospheric variations Extreme US cold linked to two variations of a stretched stratospheric polar vortex can explain a Northwest US cooling trend.

🌀 Why is it still so cold in winter?

Despite warming trends, the US still gets hit by brutal cold snaps. A new study links these outbreaks to shifts in the stratospheric polar vortex: high-altitude winds that can steer winter weather far below.

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.

The Paleo Society Government Affairs Committee presents: 2025 Geosciences Congressional Visit Days September 9 & 10. Applications due July 10. The Paleo Society logo and the American Geosciences Institute logos are in the upper corners. Pangea is in the background and art of a government building is present.

We are sending 8-10 members to participate in the Geoscience Congressional Visit Days September 9th & 10th in DC! Participation is open to all US members, including undergraduate and graduate students, faculty, staff, and avocational paleontologists. Apply today!

Climate warming is not a recent phenomenon; it has had detectable impacts on plants for at least 134 years!

Local predictions of climate change are hazy. But cities need answers fast Scientists are figuring out where “downscaled” climate models struggle—and how they can be improved

My latest feature is out: As the world has warmed, the regional flaws of climate models have grown apparent. Meanwhile, methods to localize the results of models have proliferated.

It all leads to lots of uncertainty -- within a very certain global trend. And cities need answers now.

Cuts have consequences, illustrated. As seen on TV 📺

Please tune in today to find out what federally funded research does for you!

We’ll continue to explore CCM in climate projects, including potential relevance to reconstructing paleoclimate variability. (4/4)

This project grew out of my climate diagnostics class, and was fun to work on with Haejo, assistant prof Sam Tuttle, and new assistant prof at UGA David Fastovich. This curiosity driven work was only possible with federal support! Both for computation and for our science (3/4)

Applying this technique in a spatially explicit manner helps identify regions of sea surface temperature anomalies that help quantitatively predict snow resources. For many regions in the Pacific Northwest, we identify a region of NE Pacific SST that offers strong prediction skill (2/4)

PhD candidate Haejo Kim @kim-snowed-in.bsky.social

This is the NSF's plan for the fact that it didn't have money to support anywhere near the amount of graduate research fellows this year as they usually do: They are asking business and philanthropy to fund NSF fellows, because the NSF can't afford it.
