John Kerry says he'll continue with global warming efforts

U.S. Secretary of State John Kerry says he will continue his efforts to implement the Paris Agreement on global warming until the day President Barack Obama leaves office on Jan. 20.

Speaking in New Zealand Sunday following a trip to Antarctica, Kerry said his administration would continue to do everything possible to meet its responsibility to future generations.

Kerry has long championed climate action but now his legacy is under threat. President-elect Donald Trump has called climate change a hoax and said he would "cancel" U.S. involvement in the landmark Paris deal.

Kerry said it would be up to the next administration to define itself on the issue. He said that sometimes there is a divide between what is said on the campaign trail and what is done in governance.
