Scientists, American public disagree on global warmiri!
By Robert S. Boyd

WASHINGTON — When it
comes to global wanning, scientists
and the American public
aren't talking on the same wavelength.
Most scientists believe that
humans and their machines are
mainly responsible for the
L4 degree Fahrenheit rise in the
world's average temperature in
the last 100 years. Most Americans
think otherwise.
Last month, a group of
18 climate scientists, including
two Nobel Prize winners,
submitted an affidavit to the
Supreme Court declaring that
they're 99 percent certain that
"greenhouse gas emissions from
human activities cause global
climate change, endangering
human health and welfare."
Only 41 percent of those
polled last summer by the
Washington-based Pew
Research Center, however,
accepted the argument that climate
change is due primarily to
human activities, such as burning
fossil fuels in cars, trucks
and factories.
The rest of the 1,501 adults in
the survey either said there's no
solid evidence that the Earth is
warming, or that if there is, the
extra heat is the result of natural
climate patterns, such as fluctuations
in the sun's radiation.
This public skepticism flies
in the face of the most widely
