Earth's Temperature Reaches Record High in 2,000 Years

Studies made by the The National Academy of Sciences lead to the conclusion that Earth is at its hottest in 400 years and possibly the past 2,000 years.  According to their report presented to the US Congress, the average global surface temperatures in the Northern Hemisphere was up by about 1 degree during the 20th century. This means the  fever was fanned mostly by human activities.

While the rise in temperature may not appear significant, other researches showed that global warming produced about half of the extra-strength hurricanes in the North Atlantic last year. Gerald North, a geosciences professor at Texas A&M University who chaired the academy's panel also pointed to retreating glaciers as evidence of the global warming's potentially devastating effects on the environment.

The scientists based their findings on evidence from tree rings, corals, glaciers and ice cores, cave deposits, ocean and lake sediments, boreholes and other sources as well as indirect records such as paintings of glaciers in the Alps. Although they admitted they had less confidence in the evidence of temperatures before 1600, they considered it reliable enough to conclude there were sharp increase in carbon dioxide and methane beginning in the 20th century. This after the level remained fairly level for the past 12,000 years. Carbon dioxide and methane are two major greenhouse gases thought to be responsible for for trapping heat in the atmosphere.

Although volcanic eruptions and solar fluctuations between 1 A.D. and 1850 also caused changes in greenhouse gas levels, they were less pronounced than the warming due to greenhouse gas caused by pollution since the mid-19th century. The Bush administration contends threat of global warming is not severe enough to warrant new pollution controls that could make 5 million Americans lose their jobs.

"The Bush administration contends threat of global warming is not severe enough to warrant new pollution controls that could make 5 million Americans lose their jobs."

because, of course, American jobs are WAY more important than the planet we live on....

Two points worth mentioning:

1) Americans are ALREADY losing jobs by the millions because of this Administration's trade policies

2) When the planet becomes unlivable, one suspects "American jobs" (and any others) will become a moot point...
