Besides this latest example of the Gore Effect, the dirty little secret is that the climate is always changing, and what better place to illustrate the role of Mother Nature (not humans) than in Alaska?
Extreme Weather Alaska weather matches its geography – extreme. Temperatures there have ranged from 100 deg F (in 1915) to 80 below zero F (in 1971). Summer days are so long that they can grow pumpkins weighing over 1,000 lbs. Nevertheless, yearly average temperatures are actually below freezing — even in the warmest years.
Glaciers were Already Retreating Before 1900 The supposed poster child glacier for global warming in Alaska is Mendenhall Glacier…except that it had already retreated one mile by the early 1900s, long before human greenhouse gas emissions could be blamed.
Furthermore, its retreat is uncovering large tree stumps approximately 1,000 years old, coincidentally coinciding with the (naturally-caused) Medieval Warm Period, back when the Vikings were able to farm in Greenland.
Which begs the question: How could it have been warm enough to grow giant trees 1,000 years ago in an area now covered in ice? We don’t know why it was so warm 1,000 years ago—climate scientists don’t like to talk about it because they can’t explain it — but for some reason they are sure that your SUV is causing current warmth When President Obama visits Alaska this week to campaign for a new international agreement to fight global warming climate change, Alaska will be experiencing colder than normal weather and forecast summer snows, as seen in this WeatherBell.com graphic of forecast total snowfall by Friday:
