DURHAM, N.C. –
Researchers at Duke University say global warming in not progressing as fast as it would under the most severe scenarios outlined by the Intergovernmental Panel on Climate Change.
Looking at 1,000 years of temperature records, researchers found that natural variability in surface temperatures over the course of just a decade can account for increases and dips in warming rates. Researchers said that variability could be caused by interactions between the ocean and atmosphere, or other natural factors.
As such, they say trends over just a 10-year period do not show much about long-term warming the Earth can expect to experience over a 100-year period. (more…)
