Global warming will lengthen the day - Global warming will make
days longer as well as hotter, say Belgian scientists. A team led by
Olivier de Viron of the Royal Observatory of Belgium has calculated
the impact of global warming from the build-up of greenhouse gases in
the air on the angular momentum of the planet...

Easing off the (Greenhouse) Gas
- NASA.com, Greenhouse gases are still accumulating in
Earth's atmosphere, but more slowly than before, say NASA-funded
researchers. A new NASA-funded study shows that the rate of growth of
greenhouse gas emissions has slowed since its peak in 1980, due in
part to international cooperation that led to reduced
chlorofluorocarbon use, slower growth of methane, and a steady rate of
carbon dioxide emissions...

FreedomCAR: Will It Drive? - Techreview.com, By Alan Leo,
Experts say lack of goals bedevils new U.S. fuel-cell initiative.
In 1993, Vice President Al Gore announced a research initiative
comparable, he said, to President Kennedy's mission to put a man on the
moon: by 2004, build a car that gets 34 kilometers per liter. But by
2000, it was clear the $1.5 billion program—dubbed the Partnership for a
New Generation of Vehicles—would fall short of that goal. But at least
it had a goal—one that motivated researchers, inspired the public and
provided a way to measure progress. And experts say that's what's
glaringly absent from the replacement initiative announced earlier this
month by Secretary of Energy Spencer Abraham. Called FreedomCAR, it
scrapped the Clinton/Gore plan—which focused on gaining efficiency by
linking internal combustion engines with electric motors—in favor of one
focused exclusively on fuel cells, a cleaner but more distant technology
for cars. But Abraham did not articulate what the industry had to
accomplish in a fuel-cell car, or by when...
