Making a surprise appearance at the inauguration's "Green Ball" on Sunday, Vice President Joe Biden offered encouragement to environmental activists, urging them to "keep the faith."
"I'll tell you what my green dream is: that we finally face up to climate change," Biden said, as quoted by Politico.
Biden offered no details about what the administration's approach will be but said, "I don't intend on ending this four years without getting an awful lot more done.”
He added: "Keep the faith."
And, in an apparent knock to Republicans who question climate science, he said, "There is science in the White House."
