US Arctic climate report canceled under Trump

A benchmark US report on the state of the Arctic has been canceled, while the National Academy of Sciences has removed a climate science chapter from a judges' manual during President Donald Trump's second term.

The National Oceanic and Atmospheric Administration, which has published the Arctic Report Card annually since 2006, did not explain the end of the report. NOAA said coordination of the 2026 Arctic Report Card would not be facilitated through the agency and that previous data would remain public.

NOAA said its Arctic research program would continue to support work contributing to national security, weather prediction, navigation safety and coastal economies.

The 2025 Arctic Report Card found the polar region had experienced its hottest year since records began, with effects including melting glaciers and sea ice, greening landscapes and disruptions to global weather. The Arctic is warming several times faster than the global average, a phenomenon known as Arctic amplification.

Days before the Arctic report development, the National Academy of Sciences removed from its website a climate science chapter from a manual for judges. Trump had criticised the chapter on Truth Social as “fraudulent, biased and misleading” and accused the academy of being run by “Radical Left Democrats.”

The academy said questions about the process used to develop the chapter warranted an independent review and that the chapter would remain offline while the review is underway. A spokesperson said the review was expected to be completed in the fall.

The academy had recently released a review of climate attribution science, which examines whether individual extreme weather events can be linked to climate change. Carly Phillips, a senior scientist with the Union of Concerned Scientists, said she saw a broad attack on attribution science, including from Republicans in Congress seeking to outlaw climate accountability lawsuits.

The developments follow the Trump administration's February rescission of the 2009 endangerment finding, which determined that greenhouse gas pollution endangers human health and must be regulated.
