WASHINGTON (June 23, 2013)--In an online video released by the White House, President Barack Obama says that in a speech Tuesday he will lay out his vision for reducing carbon pollution.
The goal is to prepare the U.S. for the effects of climate change and lead other nations in the global effort.
Mr. Obama's speech Tuesday afternoon at Georgetown University comes the day before he leaves for a weeklong trip to three African nations.
"There's no single step that can reverse the effects of climate change,” Mr. Obama said in the video, but adds that "when it comes to the world we leave our children, we owe it to them to do what we can."
He says scientists must design new fuels and energy sources, and workers must prepare for a clean energy economy.
