"By the way, we should be grateful to President Trump. In Moscow, it's raining and cold and even, they say, some snow," Putin told an audience at the St. Petersburg International Economic Forum.

"Now, we could blame this all on American imperialism, that it's all their fault," he continued. "But we won't."

Putin also said critics of Trump's decision, which he announced on Thursday afternoon, were overreacting and that there is time to renegotiate the agreement.

"Don't worry, be happy," Putin said. "We still have time. If we all work constructively, we can agree on something."

Other world leaders, however, have condemned Trump's decision. In an unusual joint statement, the leaders of France, Germany, and Italy roundly rejected Trump's claim that the deal could be renegotiated.

"We deem the momentum generated in Paris in December 2015 irreversible, and we firmly believe that the Paris Agreement cannot be renegotiated, since it is a vital instrument for our planet, societies, and economies," the statement said.

Although Putin has claimed that climate change is not man-made, Russia is a party to the Paris accord. The US would join Syria and Nicaragua as the only countries that have not signed onto the agreement.
