Hollywood was quick to respond as President Donald Trump announced that he plans to pull the U.S. out of the Paris climate accord on Thursday.

Former Vice President Al Gore called the decision “reckless and indefensible.” In a statement, Gore said, “It undermines America’s standing in the world and threatens to damage humanity’s ability to solve the climate crisis in time. But make no mistake: if President Trump won’t lead, the American people will.”

The Weather Channel updated its homepage to address the potential effects of the announcement.

Leonardo DiCaprio, who previously addressed world leaders to join the Paris Agreement, voiced his disappointment on Twitter and urged others to take action.

Today, our planet suffered. It’s more important than ever to take action. #ParisAgreement https://t.co/FSVYRDcGUH — Leonardo DiCaprio (@LeoDiCaprio) June 1, 2017
