Science published a study last week claiming that a tree ring analysis found striking similarities between 20th century increases in global temperature and the Medieval Warm Period — a period lasting from 1330 AD to 1600 AD which saw similar increases in temperature.
Researchers examined ancient tree rings at 14 sties on three continents. According to Edward Cook of the Lamont-Doherty Earth Observatory,
We don’t use this as a refutation of greenhouse warming, but it does show that there are processes within the Earth’s natural climate system that produce large changes that might be viewed as comparable to what we have seen in the 20th century.
Not surprisingly, the Intergovernmental Panel on Climate Change’s climate models simply ignore the Medieval Warm Period. The models simply compare current temperatures to those of the immediately preceding pre-industrial societies. It is almost as if the Medieval Warm Period simply never happened as far as the IPCC is concerned (which makes it a lot easier to claim the current warming trend is completely unprecedented and, therefore, must be due to human-induced changes in the climate.
