As recently as 2007, the absolute worst-case projections showed summer Arctic sea ice disappearing around 2100. Based on observations, scientists are now confident that will happen well before 2050, and possibly within a decade.”

How many other significant predictions have they also underestimated? 


Melting will continue through September
