Former Vice President Joe BidenJoe BidenUkrainian official denies Trump pressured president Trump goes after New York Times, Washington Post: 'They have gone totally CRAZY!!!!' Warren overtakes Biden in Iowa for first time: poll MORE on Wednesday cast climate change as an "existential threat to our future" and urged President Trump not to pull out of the Paris climate agreement.

"Climate change is an existential threat to our future – staying in [the] Paris Agreement is the best way to protect our children and global leadership," Biden wrote on Twitter.

The former vice president's warning comes as Trump is said to be considering possibly withdrawing the U.S. from the 195-nation agreement, which is aimed at broadly cutting carbon emissions and slowing the effects of climate change.
