There has been a measurable "surge" of carbon
in the atmosphere for the past 4 or 5 years, nearly doubling the annual rate of the 1970-2000 period, which has mystified scientists because it does not match human trends or known natural causes. A new paper (abstract
) suggests we may have reached a tipping point
with more greenhouse gases escaping from trees, plants and soils than in the past - hotter and dryer weather caused by high levels of CO2 is creating a feedback loop of unusually strong out-gassings of CO2 from vegetation more inside
. Penguin populations around the world are crashing. Biologists are mystified but suspect warmer oceans caused by global warming is reducing available food.
The Weather Channel launches One Degree
, a broadband channel dedicated to global warming - for the "weather obsessed", sexy-voiced climatologists Heidi Cullen brings global warming mainstream. Are you a "climatechanger"?
President Bush is preparing an astonishing U-turn
on global warming, senior Washington sources say.
Fair Price Energy
. One persons idea for a free market solution to the fossil fuel problem.
The Amazon rainforest becomes "a desert"
after three consecutive years without rain - the trees die. Next year would be the third year of an ongoing drought
. The forest contains 90 billion tons of carbon (or about 45 years of stored human emmisions at current rates
) - 3/4's of the carbon is released within a year of dieing. The Amazon is "headed in a terrible direction".
Who'll be living where. Researchers at the Earth Institute at Columbia University have developed map
that projects where people will be living in the year 2025.
The Coming Meltdown
. The incredible story
of Lonnie Thompson
- West Virginia conservative, world-class mountaineer, glaciologist, and leading climatologist who first told Congress the world is heating up in 1988, "the moment at which the greenhouse era really began".
No surprise: Warmest September (globally) since record keeping began
, according to NOAA, 1.13 degrees above the 1880-2004 long term mean, with land temperatures more than 5 degrees F above normal across large parts of Asia and North America. Ocean temperatures were third highest on record.
Scientists find errors in global warming data.
Heating from tropical sunlight was skewing temperatures reported by satelite sensors, making nights look as warm as days. The George C. Marshall Institute
declined to comment. The group, financed by the petroleum industry, has used the data disparities to dispute the views of global-warming activists. Researchers say it removes a last bastion of scientific doubt about global warming
