Abrupt Warming - As Warm As Any Time in the Holocene
« on: March 08, 2013, 03:08:39 AM »
There is a new article being published in Science tomorrow, new research which documents that we are now as warm as any time in the Holocene.

Comment Science Daily captures the significance, "We already knew that on a global scale, Earth is warmer today than it was over much of the past 2,000 years," Marcott said. "Now we know that it is warmer than most of the past 11,300 years. This is of particular interest because the Holocene spans the entire period of human civilization."
Peter Clark, an OSU paleoclimatologist and co-author on the Science article, said many previous temperature reconstructions were regional in nature and were not placed in a global context. Marcott led the effort to combine data from 73 sites around the world, providing a much broader perspective.
"When you just look at one part of the world, the temperature history can be affected by regional climate processes like El Niño or monsoon variations," noted Clark. "But when you combine the data from sites all around the world, you can average out those regional anomalies and get a clear sense of the Earth's global temperature history."
What that history shows, the researchers say, is that over the past 5,000 years, Earth on average cooled about 1.3 degrees (Fahrenheit) -- until the past 100 years, when it warmed ̴ 1.3 degrees (F)."

Look at that rate of change in the last 100 years compared to the rest. Genetic adaptation takes time.
