Climate scientists drive stake through heart of skeptics' argument
New research shows that the recent rise in global temperatures is unlike anything seen on Earth during the past 2,000 years.

Global warming skeptics sometimes say rising temperatures are just another naturally occurring shift in Earths climate, like the Medieval Warm Period of the years 800 to 1200 or the Little Ice Age, a period of cooling that spanned from roughly 1300 to 1850.
But a pair of studies published Wednesday provides stark evidence that the rise in global temperatures over the past 150 years has been far more rapid and widespread than any warming period in the past 2,000 years a finding that undercuts claims that todays global warming isnt necessarily the result of human activity.
The familiar maxim that the climate is always changing is certainly true, Scott St. George, a physical geographer at the University of Minnesota in Minneapolis, said in a written commentary about the studies. But even when we push our perspective to the earliest days of the Roman Empire, we cannot discern any event that is remotely equivalent either in degree or extent to the warming over the last few decades.
Since the beginning of the 20th century, the global average temperature on Earth has risen by about 2 degrees Fahrenheit. A consensus of climate scientists pins the increase primarily on the burning of fossil fuels, which spews carbon dioxide and other heat-trapping greenhouse gases into the air. In the absence of concerted efforts to reduce greenhouse gas emissions, the United Nations says, the global average temperature could rise an additional 5.4 to 9 degrees Fahrenheit by 2100...........................................
