Warming fastest since dawn of civilization, study showsPublication: NBC News Date: March 7, 2013 View Article
Temperatures are rising faster today than they have at any point since at least the end of the last ice age, about 11,000 years ago, according to a new study.
The finding is based on a global reconstruction of temperature records inferred from ice cores, fossils in ocean sediments and other sources. While previous studies reached similar conclusions, they covered only about 2,000 years. The new reconstruction extends the global record through the Holocene, the most recent geologic epoch.
“Another way to think of it is the period where human civilization was born, created, and developed and then progressed to where we are now,” Shaun Marcott, a climate scientist at Oregon State University who led the study, told NBC News.
