How to Prioritize Climate Change in U.S. National Security

By Kate Guy

From the outset of Joe Biden’s run for the American presidency, he pledged to look at national security with fresh eyes. Evolving systemic threats like climate change, often relegated to the portfolios of environmental experts and science agencies, were repeatedly mentioned in his plans to remake U.S. defense and foreign policy. “Climate change is the existential threat to humanity,” he often reiterated in the closing days of his campaign.

Now, with the first members of President-elect Biden’s national security team announced, it’s clear that he has taken the first steps to make good on these campaign promises. In the past few years, nominees like Blinken, Sullivan, and Haines have each referenced the need for the U.S. to prioritize addressing climate change in its approach to global challenges. And with the creation of a cabinet-level Presidential Climate Envoy, long-time climate security leader John Kerry will sit in every meeting of the National Security Council with his eye trained on climate threats.
