Warmer climates not found to induce extreme weather events past 1000 yrs., European researchers publish study

What was done

To help develop this essential palaeoclimatic perspective, the nine researchers analyzed 11,873 annually-resolved and absolutely-dated ring-width measurement series from living and historical fir (Abies alba Mill.) trees that had been sampled across France, Switzerland, Germany and the Czech Republic, and which continuously spanned the AD 962-2007 period, while demonstrating that ring-width extremes were triggered by anomalous variations in Central European April-June precipitation.

What was learned

Buntgen et al. discovered there was "a fairly uniform distribution of hydroclimatic extremes throughout the Medieval Climate Anomaly, Little Ice Age and Recent Global Warming," which result brings into question, in their opinion, "the common belief that frequency and severity of such events closely relates to climate mean states."

What it means

For the portion of Europe involved in the study of Buntgen et al., extreme hydroclimatic phenomena were found to not be amplified in either number or strength in response to global warming, which leads one to suspect that the same likely holds true for other portions of the planet, in contradiction of vociferous climate-alarmist claims to the contrary."
