Watch Live: Biden speaks at news conference as he leaves climate summit

President Biden is taking questions from reporters Tuesday evening as he wraps up his European swing in a news conference, just before he departs the United Nations climate summit. 

Mr. Biden, who brought the message to world leaders that the U.S. is "back at the table," is likely to be asked whether the commitments made at the conference by the world — and the U.S. — will be enough to bend the trajectory of Earth's warming down to levels that will preserve the planet. Mr. Biden announced Tuesday that he'll urge Congress for $9 billion for the conservation of the world's forest and ecosystems.

His administration also proposed a rule Tuesday that would cut U.S. methane emissions by cracking down on methane emissions from all of the nation's oil and gas wells. Existing regulations apply only to newer oil and gas wells, built or modified since 2015. The Associated Press notes that this means over 90% of the 900,000 wells in the U.S. are not regulated. The Environmental Defense Fund says that reducing methane emissions is the quickest route to slowing the warming of the planet because its warming power is 80 times that of carbon dioxide in the first 20 years it's in the atmosphere.
