Earth At Hottest Now Because of Humans
Good story today in USA Today... Study: Earth Is Hottest Now In 2000 Years; humans responsible for much of the warming. Highlights from the report, which was commissioned by Congress:- global warming produced about half of the extra hurricane-fueled warmth in the North Atlantic in 2005, and natural cycles were only a minor factor
- average global surface temperatures in the Northern Hemisphere rose about 1 degree during the 20th century. (And that's only the average. Some places like Greenland exceed that to a dangerous degree.)
- The National Academy scientists concluded that the Mann-Bradley-Hughes research from the late 1990s (which produced the famously contested "hockey-stick" graph) was "likely" to be true.
-"recent warmth is unprecedented for at least the last 400 years and potentially the last several millennia" (though relatively warm conditions persisted around the year 1000, followed by a "Little Ice Age" from about 1500 to 1850)
And finally, and perhaps most importantly...
- The report was requested in November by the chairman of the House Science Committee, Rep. Sherwood Boehlert, R-N.Y., to address naysayers who question whether global warming is a major threat.
Yes Virginia, that means even smart Republicans can acknowledge climate change. Refreshing.
