Nearly 15% of Americans still deny that climate change is real, according to a new national assessment from the University of Michigan.

Evidence of climate change has been mounting, including science which has shown that climate-related natural disasters are growing in frequency and intensity sooner than originally predicted, researchers said.

Nevertheless, climate change is still n...

The U.S. Environmental Protection Agency has announced that it is cracking down on air pollution.

Specifically, the agency introduced a tougher air quality standard that takes aim at fine particulate matter -- the tiny bits of pollution that can penetrate the lungs -- by lowering the allowable annual concentration of the deadly pollutant that each state can have.

“This final air q...

Deaths related to ozone air pollution will rise significantly around the world during the next two decades due to climate change, a new study warns.
