Global Warming Accelerated???

The prospects for planet earth are not looking very good these days.
I'm still putting odds on this planet dying before we will be able to
do anything about it. But then, the environmental hacks sure as hell
don't care about the planet or how badly they are screwing it up--they
have their own cut and run agenda--trash the planet, leave and then
find some other planet to exploit and destroy. Too bad it isn't going
to work.. There isn't the time, money, or resources to pull it off.
Nothing like a little reaping of what one sows. Thanks to you
unscrupulous slobs who trashed this planet...even though nobody is
getting out of here alive, it will be a joy watching you kick and
scream as your fate is sealed and there will be nothing you or anyone
else can do to save your sorry asses. You know who you are!!!
So go ahead and listen to Rush and Boortz and go right on believing
there is no global warming. After all, they will share the same fate
as you!

Oceans, greenhouse gases rising faster: reports By Susan Heavey
Thu Nov 24, 2:04 PM ET
WASHINGTON (Reuters) - Ocean and so-called greenhouse gas levels are
rising faster than they have for thousands of years, according to two
reports published on Thursday that are likely to fuel debate on global
warming.
One study found the Earth's ocean levels have risen twice as fast in
the past 150 years, signaling the impact of human activity on
temperatures worldwide, researchers said in the journal Science.
Sea levels were rising by about 1 millimeter (0.04 inches) every year
about 200 years ago and as far back as 5,000 years, geologists found
from deep sediment samples from the New Jersey coastline. Since then,
levels have risen by about 2 millimeters (0.08 inches) a year.
While the planet has been in a warmer period, driving cars and other
activities that create carbon dioxide are having a clear impact, the
Rutgers University-led team said.
"Half of the current rise ... was going on anyway. But that means half
of what's going on is not background. It's human induced," said Kenneth
Miller, a geology professor at the New Jersey-based school who led the
15-year effort.
Carbon dioxide emissions come mainly from burning coal and other fossil
fuels in power plants, factories and automobiles.
Miller and his colleagues analyzed five 500-meter (1,650-foot) deep
samples to look for fossils, sediment types and variations in chemical
composition, giving them data on the past 100 million years.
They also analyzed data from satellite, shoreline markers and by
gauging ocean tides, among other measures.
"It allows us to understand the mechanisms of sea level change before
humans intervened," Miller said in an interview.
His team did not determine whether the rate is accelerating.
The research, funded mostly by the National Science Foundation,
also found ocean levels were lower during the dinosaur era than
previously thought. They were about 100 meters (330 feet) higher than
now, not 250 meters (820 feet) as many geologists had thought, Miller
said.
SAMPLES FROM ANTARCTIC DEPTHS
Measurements also showed that, while many scientists had thought polar
ice caps did not exist before 15 million years ago, frozen water at the
poles did form periodically.
"We believe the ice sheet was not around all the time. It was only
around during cool snaps of the climate," Miller said.
In another report published in Science, European researchers using
three large samples of polar cap ice found carbon dioxide levels were
stable until 200 years ago.
"Today's rise is about 200 times faster than any rise recorded" in the
samples, study author Thomas Stocker said in an e-mail interview with
Reuters.
The historic data "put the present rise of the last 200 years into a
longer-term context," he added.
Trapped gas bubbles in the ice, drilled out from Antarctica depths of
about 3,000 meters (9,900 feet), provided scientists with information
on the Earth's air up to 650,000 years ago.
Researchers participating in The European Project for Ice Coring in
Antarctica measured levels of carbon dioxide as well as methane and
nitrous oxide -- two other gases known to affect the atmosphere's
protective ozone layer.
"The study does not directly address global warming. But what we
provide is an important new baseline for the climate models with which
we investigate global warming," said Stocker, a professor of climate
and environmental physics at the University of Bern in Switzerland.
