Perhaps the victory lap for getting rid of RCP8.5 was premature

Sunny days aren't all they're cracked up to be

How science shows us how warming makes heat waves, floods, hurricanes, and wildfires more likely or more severe — and why this science is becoming a major public-policy battleground.

Doubt is still their product
