This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

www.nature.com/immersive/d4...
This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.

In winter, when deciduous trees are bare, we can really appreciate the form of a tree. Here is a chinkapin oak, Quercus muehlenbergii, on a ridgetop in Nashville. It is now surrounded by young forest, but you can tell by its branch pattern that it grew in an open woodland pasture.

The extremely anomalous & in most cases record-breaking Nov-Dec warmth led to record-low snowpack in many areas. Heavy precipitation bolstered high elevation snowpack in some areas in late Dec despite warmth, but most basins remain far below average snow water equivalent.
Current NRCS map depicting present snow water equivalent (SWE) across the western U.S. The vast majority of basins are below average, many well below average, except for the central/southern Sierra and northern Rockies.

The Trump Administration's announced withdraw from the IPCC is disappointing, but not surprising. US scientists will continue to play key roles in the @ipcc.bsky.social. A statement from the US Academic Alliance for the IPCC:
The US Academic Alliance for the IPCC (USAA-IPCC) was formed in March 2025 in part to prepare for this possibility and to ensure that US scientists remain able to engage in IPCC work regardless of the status and role of the US government. With the support of the USAA-IPCC, more than 70 US citizens and US-based experts who are currently serving the IPCC as coordinating lead authors, lead authors, review editors and committee members will continue to play these roles. β€œUS climate scientists have made incredible contributions to understanding our planet’s life support systems and the impacts and risks of climate change. Their role as key players in IPCC reports have helped the US maintain our preeminent position in science and technology, and this global scientific cooperation will continue despite this unfortunate decision,” said Dr. Pamela McElwee, Professor of Human Ecology at Rutgers University, who serves as chair of the steering committee of the Alliance. β€œThere is a reason we call our community the global scientific enterprise. We cannot grow, innovate, or advance unless we are linked together sharing, analyzing, and deliberating on vital climate data through critical international organizations like the IPCC. In the wake of this devastating move, AGU pledges to do all it can to bridge global partnership, research, and dialogue,” said Dr. Brandon Jones, President of the American Geophysical Union (AGU), which hosts the Alliance. The Trump Administration began disengaging from IPCC prior to yesterday’s formal announcement. Since February of 2025, the US State Department has not nominated experts for involvement in IPCC work, nor supported travel to IPCC meetings for selected authors, a role they have played in all prior administrations. The US government also did not participate in either of the IPCC business sessions in 2025, the first time the US has not been in attendance since the IPCC’s founding in 1988. As a result, the USAA-IPCC has assumed a key leadership role in nominating US scientists for consideration as authors for IPCC reports, including for the Seventh Assessment Report (nominating 282 authors in April 2025) and the Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture, Utilization and Storage (nominating 33 authors in December 2025), as well as for roles on the IPCC Task Group on Data Support and for participation in several expert workshops. AGU and the USAA-IPCC have also raised funds to support travel for US scientists and technical experts selected by IPCC to attend author meetings and workshops. Since the founding of the IPCC over four decades ago, US scientists and other experts have made critical contributions, leading formal processes as Working Group co-chairs as well as filling vitally important author and reviewer roles. IPCC findings have shaped science-based policy at all levelsβ€”from global climate agreements to local resilience plansβ€”and strengthen the ability of policy communities to make informed decisions. Ensuring US scientists remain fully engaged in the IPCC and the global climate science community will lead to important new research opportunities and international collaborations that benefit the US in substantial ways. The USAA-IPCC looks forward to continuing our support of US climate experts, climate science research, and the IPCC. β€”-- The USAA-IPCC (https://www.usaa-ipcc.org/) is composed of all the US academic institutions that have observer status with the IPCC – Colby College, College of the Atlantic, Dickinson College, Emory University, Indiana University, Princeton University, Rutgers University, Washington University in St. Louis, University of California San Diego, Woods Hole Oceanographic Institution, and Yale University – together with the American Geophysical Union (AGU), which hosts the Alliance.
