ON THE HILL: ENVIRONMENTAL HERO HOSTS GLOBAL WARMING ROUNDTABLE
Yesterday, Senator Joe Lieberman hosted a roundtable discussion
on global warming. Scientists from around the nation discussed
evidence that global warming is already underway, and its
possible impact on our future.
Dr. Tom Karl of the National Climate Data Center was one of the
roundtable participants. He discussed evidence that global
climate change is already underway. Though the average yearly
temperature of the US has already risen 1 degree Fahrenheit in
the last 100 years, he cautioned that things may be worse than
they appear. Temperatures in many areas of the west, midwest,
and northeast are as much as 3 degrees warmer today than they
were 100 years ago. The speed with which these changes have
occurred is unprecedented.
Dr. Karl has also found that more of the rain and snow that falls
in the US is falling in extreme weather events. This trend leads
to huge blizzards or rainstorms in the winter that often lead to
flooding. Summers, however, have become more and more dry. Many
parts of the nation now experience a "double whammy" from flooding
in the winter and droughts in the summer. This new pattern of
weather events is beginning to severely impact agriculture,
wetlands, and wildlife and will only increase as global
temperatures rise.
<<PD NOTE: I remember reading that even a few degrees change can have great
impact - increased algae blooms that do harm, too hot for fish to survive, etc.
I also remember reading somewhere that the ice age was only a few degrees
different than now - does anyone remember this fact? - maybe in average
temp....?>>
