Global warming

"Glaciers melting at twice the rate od previous decades"

Summary: Data indicates that glaciers have melted about 29 inches in the past few years, which indicates that they are melting twice as fast as they were in the 1980s and 90s. These numbers have exceeded recent predictions and but its the long-term trends that are true indicators of change.

This is an interesting concept because 20 inches does not seem like much but over time the number is much more impacting. For example 1 decade is equivalent to 200 inches and etc. This idea of global warming is a little bit frightening to me. Wether it is naturally occurring or humans activities are causing it, its beginning to make a noticeable difference. The glaciers have been around forever and they are slowly disappearing! This has an affect on me because as they melt, the ocean levels increase which absorbs heat and melts the glaciers even faster. Then the earth may over heat and humans can not withstand a variation in temperature.
