Arctic Sea Ice Extent

Gray line in time series (right) indicate 1979 to 2000 average extent for the day shown.


Like snow sliding off a roof on a sunny day, the Greenland Ice Sheet may be sliding faster into the ocean due to massive releases of meltwater from surface lakes, according to a new study by the University of Colorado Boulder-based Cooperative Institute for Research in Environmental Sciences.

Most climate scientists and oceanographers agree that the arctic sea ice could disappear as early as 2020.  These startling changes have already been taking place as satellite and fly over photography of arctic ice cover can prove.  Although many scientists agree that the earth, on a geological timescale, is headed for an ice age, our planet is currently undergoing rapid anthropogenic warming.  There will always be a small minority of climate change deniers (like one tenured University of Alabama professor), but the scientific community as a whole has formed a consensus — Global Warming and Global Climate Change are the reality.  I think it should really be called Global Melting though, check out the imagery yourself:
