CO2 emissions up 2.7% in 2000
- Heat-trapping carbon dioxide emissions jumped
2.7 percent in the United States last year, the biggest increase since the
mid-1990s, the Energy Department reported Friday.
- a drought that hindered hydroelectric
power generation.
- The United States released 1,558 million metric tons of carbon from
fossil fuel burning in 2000, or 41 million metric tons more than in 1999.
The 2.7 percent growth rate was the biggest since a 3.6 percent increase
in 1996.
- The amount of carbon dioxide released from fossil fuel burning in
the United States in 2000 was 16 percent, more than that released in 1990,
the agency said.

Climate Change Rapid
- greenhouse gases and other pollutants could trigger
large, abrupt and potentially disastrous climate changes.
- periods of gradual changes were
punctuated by sudden temperature spikes of about 10 degrees Celsius in only
a decade.

Beyond Worst Case Scenario Green House Gases
- Global greenhouse gas emissions already beyond 'worst-case'
scenario
- Worldwide economic growth has accelerated
the level of greenhouse gas emissions to a dangerous threshold scientists
had not expected for another decade
- In Germany, Chancellor Angela Merkel called Tuesday for an international
system of global emissions trading to be adopted as part of an agreement
to flight climate change from 2012 onward.
- Germany currently has a carbon
dioxide output of some 11 tons per person per year, while the U.S. is at
around 20 tons per person.

World's carbon dioxide emissions rising at alarming rate
- "In the 1990s, CO{-2} emissions
increased by about 1.3% per year. Since 2000, the growth rate has been 3.3%
per year." The researchers calculate that global carbon-dioxide emissions
were 35% higher in 2006 than in 1990.
- What's especially troubling, notes lead author Josep Canadell of
Australia's Commonwealth Scientific and Industrial Research Organization,
is most climate scenarios used by scientists and policymakers to predict
temperature increases are based on the 1.3% rise.
- It states that carbon released from burning fossil fuels
and making cement rose from 7 billion metric tons a year in 2000 to 8.4 billion
metric tons in 2006. A metric ton is 2,205 pounds.
- Another factor is the reduced amount of carbon dioxide naturally
absorbed by the Earth's land, plants and oceans, known as "carbon sinks."
Study co-author Thomas Conway of the National Oceanic and Atmospheric
Administration's Earth System Research Laboratory in Boulder, Colo., says,
"Carbon sinks were keeping up with the increased emissions, but now they're
not."
- Canadell confirms this: "We now know that significant contributions
to the growth of atmospheric CO{-2} arise from the slowdown" of nature's
ability to take the chemical out of the air.

Strive To Pinpoint Warming Forecasts
- Moving on from the risk of global warming, scientists are now looking
for ways to pinpoint the areas set to be affected by climate change, to help
countries plan everything from new crops to hydropower dams.

Climate change far worse than thought before
- Since then, many of the 2,500-odd IPCC scientists have found climate
change is progressing faster than the worst-case scenario they had predicted.
- Global carbon dioxide emissions from fossil fuels in 2008 were
40 percent higher than in 1990.
- Over the past 25 years temperatures have increased at a rate of
0.19 degree Celsius per decade. The trend has continued over the last 10
years despite a decrease in radiation from the sun.
- The studies show extreme hot temperature events have increased,
extreme cold temperature events have decreased, heavy rain or snow has become
heavier, while there has been increase in drought as well
- New estimates of ocean heat uptake are 50 percent higher than previous
calculations. Global ocean surface temperature reached the warmest ever recorded
in June, July and August 2009. Ocean acidification and ocean de-oxygenation
due to global warming have been identified as potentially devastating for
large parts of the marine ecosystem.
- Summer-time melting of Arctic sea-ice has accelerated far beyond
the expectations of climate models. The area of summertime sea-ice 2007-09
was about 40 percent less than the average prediction from IPCC climate models
in the 2007 report.
- New ice-core records confirm the importance of GHG for temperatures
on earth, and show that carbon dioxide levels are higher now than they have
been during the last 800,000 years.
