Volcanic eruptions and resulting changes to sea ice and ocean currents may be the cause.

NCAR scientist Jerry Meehl explains the connection in this animated video.

Even as global warming coverage declines, some journalists are connecting the dots to extreme events.

The effects of a warming climate on hail are largely unknown, as global climate models are too coarse in resolution to simulate hailstorms in detail. But a new modeling study now tackles this subject, looking at the future of hail in Colorado’s Rocky Mountains over the coming decades.

New research led by NCAR scientist Thomas Galarneau provides an in-depth analysis of two extreme weather events whose connection may come as a surprise: Russia’s intense heat wave in summer 2010 and the heavy rains that occurred simultaneously in Pakistan.
