  • In summer of 2012, warm and dry climate climate conditions combined with weather to spark one of the West's largest wildfire seasons yet.

  • Arctic sea ice extent set a new record low at the end of the summer melt season on September 16, 2012. But extent is not the only quality of the ice that is changing. Wind and ocean circulation patterns are conspiring with a warmer climate to reduce the amount of year-round (multi-year) ice, transforming the remaining ice into a younger, thinner version of its old self.
