Atlantic Council Distinguished Statesman and former Secretary of Defense Chuck Hagel writes for TIME on the Paris climate talks and why climate change is a national security challenge:
It is remarkable that French security forces are taking on the international climate change conference in Paris in the shadow of the recent attacks. Then, the city reminded the world of the threat of terrorism. Now, it offers a promise for world leaders to address another national security challenge: climate change.
The agreement in Paris is expected to feature all countries voluntarily committing to reduce their emissions, and ensuring that their commitments are transparent and verifiable.
