"John Kerry is looking to resume climate diplomacy that was disrupted under President Trump.
The former secretary of state is one of several Obama administration officials appointed by President-elect Biden. Their goals include restoring what had been seen as the normal functions of the U.S. government when they were last in it.
The mission is especially clear in Kerry's case. In 2015, he signed a global climate accord as his granddaughter sat on his lap to suggest its importance to future generations. President Trump withdrew from the agreement. President-elect Biden wants Kerry to bring the U.S. back in."
