Re climate change: Seattle had 3000 feet of ice on it 15000 years ago
During the third, or Vashon Glaciation, a lobe of the Cordilleran Ice Sheet, called the Puget Lobe, spread south about 15,000 years ago, covering the Puget Sound region with an ice sheet about 3,000 feet (910 m) thick near Seattle, and nearly 6,000 feet (1,800 m) at the present Canada-US border. Since each new advance and retreat of ice erodes away much of the evidence of previous ice ages, the most recent Vashon phase has left the clearest imprint on the land. At its maximum extent the Vashon ice sheet extended south of Olympia to near Tenino, and covered the lowlands between the Olympic and Cascade mountain range. About 14,000 years ago the ice began to retreat. By 11,000 years ago it survived only north of the Canadian border. [11]
And are glaciers should be growing now; not retreating. Why? In the 19th century the world was in a cool down that reversed itself as the industrial revolution and population increased throughout the world.
