Hurtling towards the abyss: global temperatures rising at unprecedented ratess
A new report in Science confirms that global warming is occurring at a unprecedented rate.
The study shows that global temperatures skyrocketed in the last century at a rate that had previously taken 4,000 years and that the earth is hurtling towards temperatures unseen in 11,000 years.
"In 100 years, we've gone from the cold end of the spectrum to the warm end of the spectrum," said climatologist Shaun Marcott, lead author of the study. "We've never seen something this rapid. Even in the ice age the global temperature never changed this quickly."
Marcott said that current "global temperatures are warmer than about 75 percent of anything we've seen over the last 11,000 years or so." By 2100, he said, global temperatures will be "well above anything we've ever seen in the last 11,000 years."
"The climate changes to come are going to be larger than anything that human civilization and agriculture has seen in its entire existence,"NPRquotes Gavin Schmidt, a climate researcher at NASA's Goddard Institute for Space Studies, as saying. "And that is quite a sobering thought."
