Thirty-five years ago, NASA climate scientist James Hansen stood in front of Congress with a bold declaration: Humans are causing an increase in greenhouse gas emissions, and it’s changing our ...

Climate scientist James Hansen is frustrated. And he’s worried. For nearly 40 years, Hansen has been warning the world of the dangers of global warming.

The planet is on track to heat up at a much faster rate than scientists have predicted, meaning a key global warming threshold could be breached this decade, according to a new study co-authored ...
