***National Research Council Reports on Climate Change
Global warming could well have "serious adverse societal and ecological
impacts by the end of this century," according to a report released on June
6 by the National Research Council. The report, commissioned by the White
House and prepared by 11 of the nation's leading climate scientists,
summarizes the current state of knowledge on climate change.
The report confirms that the climatic changes observed during the past
several decades are most likely due to human activities, although the
authors warn that they "cannot rule out" the possibility that the climate's
natural variability could be responsible for a significant portion of the
trend. The authors agree that human-induced warming and sea level rise are
expected to continue through the 21st century and beyond, but they
emphasize that current predictions of the magnitude and rate of future
warming "should be regarded as tentative and subject to future adjustments
(either upward or downward)."
The report generally concurs with the latest conclusions of the
Intergovernmental Panel on Climate Change, which found that the Earth
warmed by about 1 degree Fahrenheit during the 20th century, and that most
of the warming of the past 50 years is probably due to increases in
greenhouse gas concentrations in the atmosphere.
