President Trump’s energy plans have been making headlines, but his latest moves are having a more immediate impact on how the U.S. tackles climate risks. From national security to home insurance, his policies are reshaping the country’s approach to climate adaptation—and not everyone is on board.

One of the biggest changes came this week when Trump rolled back a key order from the Biden administration. Back in 2021, President Biden had directed the Pentagon and Department of Homeland Security to study how climate change could affect national security. The findings were eye-opening: food shortages, water disputes, and mass migration were all flagged as potential threats. But Trump’s decision to scrap that order means these risks might no longer be a priority in defense planning.

Adding to the shift, Trump’s pick for defense secretary, Pete Hegseth, has been vocal about his skepticism toward climate change, calling it a tool for expanding government control. While the Pentagon can still consider climate risks in its strategies, the tone at the top suggests a different focus moving forward.

Another area feeling the impact is government operations. Under Biden, federal agencies were required to report how climate change could affect their facilities and what they were doing to address those risks. For example, the Smithsonian Institution warned that flooding could threaten several of its museums on the National Mall. Now, those reports are no longer mandatory, leaving some to wonder how prepared the government really is.

These changes are happening fast, and their effects could ripple across everything from disaster preparedness to how Americans insure their homes. Whether you agree with the policies or not, one thing’s clear: the way the U.S. handles climate risks is shifting—and it’s happening now.
