ARE ALL THE GLACIERS & ARCTIC MELTING?:
Global Warming says that the heat of the atmosphere causes the ice to melt in the Antarctic and that there are ice shelfs that are degrading and falling into the sea because of this global temperature increase. As seen from the Larsen B Ice Shelf that fell into the sea, there was volcanic activity heating up the water and atmosphere and causing the ice to degrade until it fell. This Wilkens Ice Shelf, which most recently fell in may have been because of the warming atmosphere but this can not be studied until the fallen ice is cleared out of the Wilken's Ice Shelf area. Other parts of Antarctica have been found to be collecting great amounts of snow, ice and decreasing temperatures. |

Global Warming says that there should be more droughts occuring now then any other time. In the winter of 2007-2008, the amount of snow that has fallen has been well above average that the snowpack is 124% higher than average, setting records in some areas, and because of this snowpack, Lake Powell will raise 40'-50' and Lake Mead between 10'-20', depending on how much Glen Canyon's dam will send down to Lake Mead to be stored, since all rocky mountain runoff goes though Glen Canyon Dam. This extra precipitation though could be because of extra water in the ocean from antarctic glaciers and ice shelves that have melted. This extra water could have evaporated and floated over land to fall as snow and rain, causing more snowpack. |
| Glaciers both shrink or grow, it has not been proven if this is done because of global warming or out of natural adjustments. Two glacial examples are the Mendenhall Glacier and the Hubbard Glacier, both near Juneau, Alaska. One, the Mendenhall Glacier has been shrinking for 200+ years. Two, the Hubbard Glacier, has been growing for the past 100+ years. Global Warming and CO2 emissions have been recorded to be hurting the environment for possibly 100 years. This glacial movement may not be effected by human activity and GW. |
