"Why It Matters: Climate Change"

"WASHINGTON — THE ISSUE: It's as if Hillary Clinton and Donald Trump live on two entirely different Earths: one warming, one not.

Clinton says climate change 'threatens us all,' while Trump tweets that global warming is 'mythical' and repeatedly refers to it as a "hoax." Measurements and scientists say Clinton's Earth is much closer to reality.

As heat-trapping gases in the air intensify and hot temperature records shatter, global warming is taking a toll on Americans' everyday life : their gardens, air, water, seasons, insurance rates and more."
