The United States marked its return to the global fight against climate change yesterday by joining high level talks on ways to better protect people and economies from the effects of global warming already taking place.

Less than a week after President Joe Biden announced the return of the United States to the 2015 Paris Climate Agreement, his Special Climate Envoy John Kerry joined China's Deputy Prime Minister Han Zheng, German Chancellor Angela Merkel, French President Emmanuel Macron, British Prime Minister Boris Johnson and other leaders at the Climate Adaptation Summit.
