BOSTON (AP) — Secretary of State John Kerry said Wednesday that the country and the world need to confront the threat of climate change while there’s still time.

Kerry said climate change is already changing the world in real and significant ways, from serious food shortages to increasing temperatures to the threat of rising sea levels. But those changes also bring the potential of millions of new jobs to develop the renewable energy industry, he said, provided the U.S. and the rest of the world act now.
