Trump administration halts Princeton climate research funding, citing rise in youth anxiety

The Trump administration has cut nearly $4 million in climate research funding to Princeton University, claiming the programs cause unnecessary alarm and contribute to youth anxiety.

Brad Plumer and Austyn Gaffney report for The New York Times.


In short:

  • The Commerce Department announced it would stop funding a major climate modeling partnership between the National Oceanic and Atmospheric Administration (NOAA) and Princeton, accusing it of promoting “exaggerated” climate threats.
  • Nobel Prize-winning meteorologist Syukuro Manabe had contributed to the now-defunded program, which aimed to model ocean-atmosphere changes and support educational initiatives for K-12 students.
  • Additional cuts target Princeton-led studies on water availability and coastal flooding, part of a wider federal pullback on climate-related grants across agencies.

Key quote:

“Sadly, climate-related risks will not vanish if they are denied. With the deliberate choice to undermine climate science, knowledge production and science-based university programs, people will be less informed, less prepared.”

— Valérie Masson-Delmotte, climate scientist at the University of Paris-Saclay

Why this matters:

As the climate crisis deepens, the decades-long collaboration between Princeton University and the National Oceanic and Atmospheric Administration has improved the precision of climate models that inform everything from local floodplain maps to international climate negotiations. These models help communities plan for extreme weather, industries brace for supply chain disruptions, and health officials respond to heatwaves and air quality threats. Now, under President Trump’s second term, federal scrutiny of climate-related research has intensified, with proposals to defund or dismantle programs viewed as politically charged. The administration frames it as a reorientation of agency priorities, but scientists and public officials alike warn it could seriously compromise the nation’s preparedness in the face of worsening environmental conditions.

Increased autism risk linked to exposure to wildfire smoke during pregnancy

In a first-of-its-kind study published in Environmental Science and Technology, researchers found that mothers who were exposed to wildlife smoke during the third trimester of pregnancy were more likely to have children diagnosed with autism by age 5.


In short:

  • More frequent exposure to wildlife smoke during pregnancy was associated with a higher risk of autism in children.
  • The study analyzed more than 200,000 mother-child pairs in Southern California between 2006 to 2014; nearly 60% of them were exposed to wildfire smoke for more than 5 days during pregnancy.
  • The authors also found that prenatal exposure to particulate matter air pollution from a variety of sources — not just wildfires — is associated with an increased risk of autism in children.


Key quote:

“As climate change increases the frequency and intensity of wildfires in many parts of the world, understanding their relationship with autism is important to being able to develop preventive policy and interventions that will protect pregnant women and their children.”

Why this matters:

As climate change continues to impact global weather patterns, wildfires have become increasingly intense and frequent. Their impact on air pollution is significant - in California, wildfires account for over 70% of the fine particulate matter exposure on days with poor air quality. Environmental hazards that affect the health of pregnant people and their children can have long-term and severe outcomes. The authors of this study underscore the need for policies that protect vulnerable populations from air pollution and reduce the inequality in its health impacts.
