Deadly rivers in the sky A new Washington Post investigation reveals where climate change has supercharged the movement of moisture through the skies.

Heavy rain is one of the most unpredictable and underappreciated climate threats. The Post found rising temperatures have made the atmosphere more waterlogged - providing fuel for wetter + more dangerous storms:

🔴 A huge blob of unusually warm water spans the North Pacific 🔴

Dubbed 'the blob,' this feature is displacing the jet stream to the north, which will cause unseasonably warm conditions in Canada and the United States during October.

See it and learn about what’s causing it.
