Re: Nuclear Power Des NOT Need Gobal Warming Hoax!
Ruth and Howard,
What makes you so sure this is a hoax? There's some basic science support
global warming. Here's an excerpt from a CNN article on the new Day After
Tomorrow movie reporting how science currently weighs in on climate change
theories. A few quick quotes from the article: "Few scientists dispute
evidence the world is warming", "There is no doubt that humans are warming
the planet, says Dr. Jeffrey Severinghaus, a geoscience researcher at the
Scripps Institution of Oceanography" and "but even skeptical scientists
concede humans are probably driving some of the rising temperatures". This
article also promotes nuclear power as means to change the global warming
equation. Well, I guess both of you have seen some strong evidence that
shows otherwise. If so, I'd be interested in what it is.

Science weighs in
As the movie becomes more politicized, what are scientists saying?
"The consensus is probably that humans are having an effect on the climate
that is marginally detectable," says Alabama professor Christy, adding that
other scientists believe the evidence is stronger.
He says that the catastrophic consequences of climate change are debatable,
particularly how much humans have a hand in it.
"The majority of scientists would lean toward the middle range of
prediction," forecasting a 5 degree Fahrenheit rise over the next 100
years, says Christy.
Few scientists dispute evidence the world is warming.
Eleven of the warmest years on record have occurred since 1990, according
to the Massachusetts-based Woods Hole Oceanographic Institute.
Sea levels have risen 0.3 to 0.7 feet over the last century along with a
0.4- to 0.8-degree Celsius rise in average global temperatures, reported
the Intergovernmental Panel on Climate Change, a United Nations committee.
During that time, the concentrations of greenhouse gases such as methane
and carbon dioxide have reached their highest levels in 420,000 years NASA
climatologists reported.
"There is no doubt that humans are warming the planet," says Dr. Jeffrey
Severinghaus, a geoscience researcher at the Scripps Institution of
Oceanography. "That's very clear now. The data is very strong. Humans are
changing the climate and we're expected to change it a lot more in the
future."
Severinghaus, who studies gas bubbles in ancient glaciers, says the
possibility of an abrupt change -- while unlikely -- is grim.
A worse-case scenario over the next 200 years could lead to shifts in
historical climate patterns, devastating agriculture in developing
countries, says Severinghaus. Flooding from rising sea levels -- depending
on the extent of polar melting -- would threaten low-lying islands and
coastal cities.
The study commissioned by the Pentagon also suggested that destabilizing
effects from rapid climate change could spark wars between developing
countries vying for food and fresh water and were "a U.S. national security
concern."
Future fallout
The biggest schism in the scientific community comes over how to interpret
the warming data, but even skeptical scientists concede humans are probably
driving some of the rising temperatures.
Dorothy Hall, a glacier researcher with NASA's Goddard Space Flight Center
in Maryland, says data on how human activity affects climate is incomplete.
"Humans are probably enhancing a natural global warming that started at the
end of the 'Little Ice Age' in 1850," she says, referring to a historical
period of colder climate between 1300 AD to about 1800 AD.
Research over time will be needed to precisely gauge the extent of climate
change. Some researchers say they are not concerned just yet.
Christy says climate models are "over-predicting." Energy innovations in
the coming years -- from nuclear power to burying carbon dioxide
underground -- may change the climate equation.
But others point out the dire consequences of ignoring the potential for
global warming.
"It's like your house burning down," says Severinghaus. "You don't think
your house is burning down, but you go ahead and buy fire insurance."
