Glacier National Park in 1850 had 150 glaciers.
Today, in Glacier National Park there are ... 25 glaciers.
What will we call Glacier National Park when all the glaciers melt?

Carbon dioxide controls Earth's temperature
Quote:
Notably, the team identified non-condensing greenhouse gases -- such as carbon dioxide, methane, nitrous oxide, ozone, and chlorofluorocarbons -- as providing the core support for the terrestrial greenhouse effect.
Without non-condensing greenhouse gases, water vapor and clouds would be unable to provide the feedback mechanisms that amplify the greenhouse effect. The study's results will be published Friday, Oct. 15 in Science.

Edit 1: Another amplifying/feedback loop: when there is more open water in the Arctic Ocean, it absorbs more heat from the sun, because the albedo of the dark water is much lower than the albedo of snow and ice; which reflects the light and the heat more.
Edit 2: Ten hottest years on record:
2005
1998
2002
2003
2004
2001
1997
1990
1995
1999
Edit 3:
The tropics have expanded 2 degrees latitude north and south since 1980. This added 8.5 million square miles of tropical climate. This has pushed the subtropics toward the poles, moving the weather patterns with them.
