"The National Academy of Sciences, reaching that conclusion in a broad review of scientific work requested by Congress, reported Thursday that the "recent warmth is unprecedented for at least the last 400 years and potentially the last several millennia."
A panel of top climate scientists told lawmakers that the Earth is running a fever and that "human activities are responsible for much of the recent warming." Their 155-page report said average global surface temperatures in the Northern Hemisphere rose about 1 degree during the 20th century."
1 degree huh? Yawn.
The most interesting thing is that nowhere in the entire story are the words "sun" or "solar" used. Until a study is done which excludes the main source of heat on Earth as a cause of global warming, I refuse to take this any more seriously than a guy walking down the street with a sign saying "Repent! The End Is Near!".
UPDATE: You have to love CNN.com. They wear their bias on their sleeves. They have updated their headline story. Now it is "Study: Earth 'likely' hottest in 2,000 years". Mind you, the original article had the following quote:
"Climate scientists Michael Mann, Raymond Bradley and Malcolm Hughes had concluded the Northern Hemisphere was the warmest it has been in 2,000 years. Their research was known as the "hockey-stick" graphic because it compared the sharp curve of the hockey blade to the recent uptick in temperatures and the stick's long shaft to centuries of previous climate stability.
The National Academy scientists concluded that the Mann-Bradley-Hughes research from the late 1990s was "likely" to be true, said John "Mike" Wallace, an atmospheric sciences professor at the University of Washington and a panel member. The conclusions from the '90s research "are very close to being right" and are supported by even more recent data, Wallace said."
In other words, they are not saying anything new with the new article. Just beating the dead horse. Of course, they will blame the horse's death on global warming.
