Hi there! I’m Jacob Warner, and I am a paleoclimatologist and archaeologist. I study past climates, mostly through the geochemistry of archaeologically sourced mollusks. I’m also interested in how people adapted to climate change in the past.

1/ ICYMI yesterday, from my colleague Danny Cusick: NOAA said over a month ago that it would fill 126 open positions at the NWS (since the start of the year, NWS has lost around 600 staffers). They still haven't advertised the jobs.

Republicans won’t defy Trump unless their constituents absolutely force them to. That means our job is to make Trump’s Tax Scam politically toxic. If you live in a GOP district, let your representative know they risk losing their job by defunding Medicaid and SNAP to make billionaires richer.

This is horrible. I don't even know what to say. Some of our most key polar data.

"As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported."

nsidc.org/data/user-re...

Effective May 5, 2025, NOAA’s National Centers for Environmental Information (NCEI) will decommission its snow and ice data products from the Coasts, Oceans, and Geophysics Science Division (COGS). As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported. This includes Sea Ice Index, Snow Data Assimilation System (SNODAS) Data Products, Glacier Photograph Collection, U.S. National Ice Center Arctic Sea Ice Charts and Climatologies in Gridded Format Gridded Monthly Sea Ice Extent and Concentration, 1850 Onward World Glacier Inventory. If you rely on these products in your work, research, education, or planning, we invite you to share your story at nsidc@nsidc.org. Your input can help us demonstrate the importance of these data sets and advocate for future support.

Most Americans frequently use federal science information. But few are concerned that cuts to federal science spending could affect their access to such information, a new poll finds.

This new White House executive order says that the US Attorney General is going to prevent states from implementing democratically passed laws regarding climate change and clean energy. It scarcely needs stating at this point that this is wildly, unambiguously unconstitutional. Dictator shit.

If you see these little mounds this time of year in Eastern North Carolina, leave them be. They are not ants. They are little ground bees. Each mound has one little female bee. They won't stay in there very long so I try not to walk over them or drive over them. We need every pollinator.

A tricky thing about modern society is that no one has any idea when they don’t die.

Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.

This checklist is shocking. A person can be declared an "Alien Enemy" based ONLY on communications with someone ICE says is a member, and nothing more.

6 points for texting a "known member of TDA" + 3 points for Venmoing or CashApping a "known member" = 9 points = TDA member = sent to CECOT.

Documents and Communications
a. 6 Points: Written or electronic communications (e.g., e-mails, letters, texts, secure messages) that discuss business with, and/or are communicating with, known members of TDA; cell phone data contains multiple group, organizational, or organization leaders’ or members’ information.
b. 10 points - Subject conducts phone calls about the business of TDA with known members of TDA
c. 3 points - Financial transactions indicating criminal activity for TDA or with known members of TDA
d. 6 points: Subject possesses written rules, constitution, membership certificates, bylaws, etc., indicating, together with other conduct, membership of or allegiance to TDA

1400+ miles from Somerville, Massachusetts, where she was taken.

A judge ordered to not take her out of state without 48 hour notice. She was detained last night.

Omaha and Rapid City losing balloon launches altogether, with launches cut in half at 6 other sites.

Losing this many launches could affect severe weather forecasting and computer models.
