Quick Facts On Global Warming
* Average temperature of the world has climbed 1.4 degrees Fahrenheit / 0.8 degree Celsius, since 1880, much of this in recent decades.
*Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or earlier. Polar bears and indigenous cultures are already suffering from the sea-ice loss.
* Glaciers around the world could melt, causing sea levels to rise while creating water shortages in regions dependent on runoff for fresh water.
*Glaciers and mountain snows are rapidly melting—for example, Montana's Glacier National Park now has only 27
glaciers, compared 150 in 1910. In the Northern Hemisphere, the thawing processes come a week earlier in spring and the freezing processes begin a week later.
* Humans are pouring carbon dioxide into the atmosphere much faster than plants and oceans can absorb it.
