ARCTIC ICE MELTING FASTER THAN IN 2007
As this BBC report details, the Arctic ice is already melting faster than it did in 2007, the year in which it shrank to a record minimum, which is leading scientists to predict that Arctic summers will be ice-free within 5-10 years.
That prediction used to be for 2080, then it was moved forward to 2050, then to 2030 (now one leading scientist has been reported elsewhere as saying that it might even happen this year).
