100 degrees in Siberia? 5 ways the extreme Arctic heat wave follows a disturbing pattern

The Arctic is warming about twice as fast as the planet as a whole, with serious consequences. Scientists have been warning about this for decades.

Atmospheric river storms can drive costly flooding – and climate change is making them stronger

Earth's biggest rivers are streams of warm water vapor in the atmosphere that can cause huge rain and snowfall over land. Climate change is making them longer, wetter and stronger.
