Long before we experience protracted, detectable heat
waves from
global warming, we experience the effects of a more unstable
climate
-- altered drought and rainfall patterns, more intense
storms, more
temperature extremes, unseasonal weather events and more
intense and
severe downpours.

Findings published in the journal Science in
September,
2000, reinforced previous projections of
increasingly destructive weather as climate change
progresses.
That study follows two previous studies by
Karl et
al. which had established the connection between greenhouse
warming
and extreme weather events: "Trends in U.S. Climate during the Twentieth
Century, Consequences, Spring,
1995, Vol. 1,
No. 1, Thomas Karl et al. Also: "The Coming
Climate," by Thomas R. Karl, Neville Nicholls and
Jonathan
Gregory, Scientific American, May, 1997.
A 2003
report by
the World Water Council noted a steady
increase in extreme weather events over the past 40
years --
with "major flood disasters" rising from 7 in the 1970s, to
18 in
the 1980s to 26 in the 1990s.
Some highlights from 2001:
At the beginning of
2001,
Britain emerged from its wettest winter in
more
than 270 years of record keeping.
In early February, 22
successive
blizzards in northern China stranded more
than
100,000 herders, many of whom starved.
In South
Florida, the
worst drought in 100 years triggered more than 1,200
wildfires.
In early May, some 40
people died in
the hottest spring on record in Pakistan.
In June,
Houston
suffered the single most expensive storm in modern
history
when it received 35 inches of rain in one week, leaving $6
billion
in damages.
By late July, a
protracted drought in
Central America had left more than 1.5
million
farmers with no crops to harvest. As a result, about one
third of
the combined populations of Honduras, Nicaragua,
Guatemala
and El Salvador are suffering from malnutrition.
In
Iran, a
devastating drought left more than $2.5 billion in
agricultural
losses. The drought was temporarily interrupted in August by
the
worst flash flooding in 200 years in that country that
killed nearly
500 people.
In November, the worst
flood in memory
killed more than 1,000 people in Algeria.
In
Boston, after an
October and November of record setting warmth, it was 71
degrees F.
on Dec. 1.
2005 emerged as the hottest year on
record,
followed by 1997, 2002
and 2001.
