Tree Ring Study Shows Overall Cooling Trend, Recent Temperature Spike
According to a new study by German scientists (in fact they are Geographers), an examination of tree rings has shown that the Roman and pre-Roman periods of Europe were actually warmer than the Medieval Warm Period. The study shows how from 138 BC up to the 1900s experienced a very notable cooling trend. This trend has, at least for now, been stopped by recent warming trends.
The tree rings challenge all sides of the global warming/climate change debate. The rings show yet again that there is a warming trend. However, it shows that the past was warmer and that climate change occurred naturally. Yet again all scientists must wonder what temperature setting, if any, is optimal, and what forces are at work influencing climate change in all regards. With any hopes this will help silence alarmists who only cloud the climate change debate.
