Glacier Bay

I found the map that the National Park Service provided to us of Glacier Bay National Park absolutely fascinating. It shows the extent of the glaciers by date. In the image below, they are the black lines with the years listed.

The greatest recorded extent of the glaciers is in 1750. And the glaciers have been receding ever since. As Carla said: well before the invention of the SUV.

In fact, our scientists had been saying that we were experiencing global cooling (and the next mini ice age) up until the year 1979. It wasn’t until the early 1980s that “settled science” said that man made global warming was the cause of the glaciers receding.

But if that’s actually the case, what caused the glaciers to start receding back in 1750? And all this happened 200 years before CO2 levels started rising in 1950.
