Major climate change reports vanish from US federal websites, raising transparency concerns

Federal climate reports that help communities plan for extreme weather and rising seas have quietly disappeared from public websites, with little explanation from the Trump administration.

Seth Borenstein reports for The Associated Press.


In short:

  • National Climate Assessments and other key data have been removed from their official websites, with no clear explanation or replacement links, despite being required by law.
  • NASA is reportedly taking over the data hosting, but searches on its websites turn up nothing, and federal agencies have not responded to inquiries.
  • Climate scientists warn the missing reports hinder local governments’ ability to prepare for climate risks like flooding, wildfires, and health threats.

Key quote:

“It’s a sad day for the United States if it is true that the National Climate Assessment is no longer available.”

— Kathy Jacobs, climate scientist, University of Arizona

Why this matters:

Local governments rely on federally published climate data to prepare for worsening storms, heat waves, droughts, and rising sea levels. The National Climate Assessment — compiled by multiple federal agencies and reviewed by the National Academy of Sciences — provides county-level insights that influence decisions like where to build, how to protect vulnerable infrastructure, and how to safeguard public health. Pulling this information offline not only disrupts emergency preparedness but also weakens public understanding of climate change impacts, especially in communities already at greater risk. Scientists see it as part of a broader rollback of environmental transparency and say it could cost lives. Without access to the best available science, cities and states are left guessing as they face an increasingly unpredictable climate.

Climate change is accelerating health threats worldwide

Climate change is accelerating health threats worldwide

The Lancet Countdown - established in 2016 to annually assess the effects of climate change on health - released a ten year report and accompanying editorial.


In short:

  • For the first time, the report quantifies heat-related deaths attributable to climate change, estimated at about 370,000 a year. The past 11 years have been the hottest ever recorded.
  • The report examined 54 indicators of climate change-driven health impacts and found that many health threats had increased or accelerated over the past decade.
  • Populations least responsible for climate change are experiencing the highest impacts.


Key quote:

“Over the past 10 years, a strong evidence-based case has been made that responding to climate change could be the greatest health opportunity of the 21st century.”



Why this matters:

The report points out how fossil fuel interests are blocking progress on climate change. It tracks not only heat-related deaths, as mentioned above, but also other climate related effects on health caused by floods, landslides, droughts, viruses, and more. It also tracks improvements, for example, estimating that the transition to clean energy prevented 400,000 deaths in 2023 just through improved indoor air quality. Health professionals are trusted sources of information and can speak for policy change and action for a healthier future.
