Study Hints at Extreme Climate Change
October 28 Abrupt climate changes could be normal in Earth's climate future, report
climate researchers. Scott Lehman at the University of Colorado's
Institute of Arctic and Alpine Research says there is clear evidence that
the Atlantic Ocean was undergoing very large and rapid temperature changes
during the last glacial period that affected global temperatures by up to 9
degrees Fahrenheit. (Environmental News Network)
Climate Can Change Quickly
October 28 Researchers have found evidence that the world's climate can change
suddenly, almost like a thermostat that changes from cold to hot. Jeffrey
P. Severinghaus at Scripps Institution of Oceanography reports there was an
abrupt 16-degree warming at the end of the last ice age and that greenhouse
warming may trigger another one of these rapid climate changes. (Paul

Warmer Winter Seen for South
October 27 Americans across the South can anticipate a milder than usual winter, but
stormy weather is the outlook for the Northwest and Great Lakes states,
according to meteorologists. James Baker, head of the National Oceanic and
Atmospheric Administration, says that La Niña is to blame for the predicted
warm, dry winter in the South and the wet, snowy winter in the North.

Under Antarctica, Clues to an Icecap's Fate
October 26 Images of Antartica from NASA's Radarsat satellite are expected to help
in forecasting low-lying parts of the world, including Bangladesh, the
Netherlands, and even New York City say researchers. Ghassem Asrar,
associate administrator for Earth sciences at NASA headquarters, says that
Radarsat and other new satellites are showing a holistic view of the
continent and are opening a new window on Antarctica. (Malcolm W. Browne,

La Niña Keeps Northern California Forecasters Guessing
October 26 Northern California faces a second winter with a threat of major
flooding, warn state officials. Elizabeth A. Morse, of the National
Weather Service says that there is a tendency for La Niña events to last
more than one year, and even during dry events there is always one month
where precipitation levels are above normal. (John D. Cox, Sacramento Bee)
La Niña Reappears in Pacific
October 22 Scientists are predicting a wet winter across the Northwest and a dry one
in the Southwest of the U.S. after discovering the reappearance of La Niña
in the Pacific Ocean. William Patzer, an oceanographer at NASA's Jet
Propulsion Laboratory, said that the resurgence of La Niña will undoubtedly
exert a strong influence on North America's climate this fall and winter.

Warming Trends -- Global Effects Felt Worldwide
October 19 New York and Tokyo may face flooding, Latin America will suffer from
drought, and Australia's Great Barrier Reef may be destroyed unless more
is done to stop global warming, the World Wildlife Fund (WWF) for Nature
warned today. With no action to curb emissions, the climate on Earth over
the next century could become warmer than any human species has lived
through reports the group reports. (Associated Press)
Model May Help Predict Hurricanes
October 14 Accurately predicting the intensity of a hurricane may be easier than
previously thought suggest scientists. Kerry Emanuel, an atmospheric
scientist at the Massachusetts Institute of Technology, says that the goal
of this climate model is to understand what controls the intensity of a
hurricane, but the model may also be useful in hurricane predictions.

Talks Focus on Most Abundant Greenhouse Gas
October 12 The effect of water vapor, the most abundant greenhouse gas, on global
climate is significant report scientists. At the Chapman Conference on
Water Vapor and the Climate System, organized by the American Geophysical
Union, scientists will present results on water vapor as a greenhouse gas
and water vapor's role in the hydrologic cycle. (Environmental News

Report Plays Down Global Warming in Antarctic Ice Melt
October 8 The massive West Antarctic Ice Sheet may be headed for a complete
meltdown in a process that was triggered thousands of years ago and not as
a result of global warming, a new study suggests. Scientists at the
University of Washington say that complete disintegration of the ice sheet
could be inevitable. (Associated Press)
Melting Arctic Slab to Lift Sea Levels 20 Feet
October 7 A melting ice sheet half the size of Alaska has scientists predicting a
sea level rise of about 20 feet over the next 7,000 years. Scientists from
the University of Washington and the University of Maine report that the
360,000-square-mile West Antarctic Ice Sheet should be completely melted in
the next 7,000 years. (Eric Sorensen, Seattle Times)
Global Warming Fight May Cost Less
October 7 Fighting global warming could cost the United States and other industrial
nations much less money than analysts have predicted. The cost of
complying with the Kyoto Protocol maybe up to 60 percent less than
estimated when efforts are made to reduce all six types of gases covered by
the Protocol, says John Reilly at the Massachusetts Institute of
Technology. (Chris Tomlinson, Associated Press)
NASA Images Show Shrinking Ozone Hole
October 1 NASA images reveal the ozone hole is shrinking. Paul Newman, atmospheric
physicist at NASA's Goddard Space Flight Center, says that the hole is
still really big, but it is slightly smaller than last year. Newman
predicts that the hole won't disappear completely till 2060. (Ann Kellan,
