Obama, DiCaprio team up against climate change
WASHINGTON — President Barack Obama and actor Leonardo DiCaprio teamed up on the White House South Lawn on Monday to sound a call for urgent action to combat climate change.
Obama told a crowd gathered for the “South by South Lawn” festival of technology and music that the world is in “a race against time” to combat climate change.
The president said the world gets an “incomplete” grade on its response to global warming so far, but he added that “the good news is we can still pass the test.”
“I tend to be a cautious optimist about our ability to make change,” Obama said.
