The new population estimates from the 2016 Scientific Working Group are somewhere between 22,633 to 32,257 bears, which is a net increase from the 2015 number of 22,000 to 31,000. The current population numbers are a sharp increase from 2005’s, which stated only 20,000 to 25,000 bears remained — those numbers were a major increase from estimates that only 8,000 to 10,000 bears remained in the late 1960s.
New estimates for polar bears in Svalbard and Baffin Bay/Kane Basin are likely to increase the global estimate of polar bears to 23,000-33,000.
75% Of Total Modern Glacier Melt Occurred Before 1950: “[T]he retreat of the glaciers after about 1925 became rapid. It was almost entirely during the [pre-1950] twentieth century warming that the Alpine glaciers disappeared from the valley floors up into the mountains. Similarly great retreats occurred in Scandinavia, Iceland, Greenland, in the Americas, and on high mountains near the equator.” — H.H. Lamb Climate, History, and the Modern World (1982), pg. 248
A new scientific paper indicates that the pronounced warming that occurred during the years stretching from the 1920s to the 1940s melted Northern Iceland glaciers much more extensively and at a far more rapid pace than has been observed in recent decades.
