Department of Homeland Security Climate Change Research Act

Introduced June 8, 2021

AI-Generated Summary

Updated February 8, 2026 at 4:02 AM UTC

The bill amends the Homeland Security Act of 2002 to require the Department of Homeland Security’s Under Secretary for Science and Technology to evaluate existing federal research on how climate change impacts homeland security, pinpoint research gaps, and conduct new research and development to mitigate those effects. It also defines “climate change,” mandates coordination with other agencies, first responders, and critical‑infrastructure owners, and obligates DHS to submit annual reports to Congress for three years. The changes affect DHS, other federal agencies, emergency responders, and infrastructure stakeholders.

Key Provisions

  • The Under Secretary must assess current federal research on climate‑change links to homeland security, including resource competition, economic distress, social unrest, terrorism, and disaster preparedness.
  • Identify gaps and conduct new research and development to lessen climate‑change consequences for security, emergency response, and recovery.
  • Research scope covers connections between climate change and terrorism, integration of climate considerations into terrorism preparedness and disaster planning, and the adequacy of federal disaster‑funding structures.
  • The Under Secretary must consult with heads of relevant agencies, first responders, and owners/operators of critical infrastructure while carrying out the research.
  • DHS must submit a report to the House and Senate committees on its research and development activities annually for the first three years after the law takes effect.
