Climate

California is home to some of the country's strictest environmental regulations. Those standards can sometimes spread to other states and beyond. It's known as the "California Effect."

Extreme weather which is fueled by climate change is posing a bigger and bigger threat to the nation's water infrastructure.

The Earth has already warmed more than 1 degree Celsius. New research suggests that above 1.5 degrees, massive ice melt, ocean current disruptions and coral die-offs are likely.

Our bodies couldn't endure the summer heat without sweating. But as the climate gets hotter, sweat isn't cooling us off like it used to.
