Floods and extreme precipitation were more common during the Little Ice Age

A recent paper published in Quaternary Research examines floods in the Mediterranean French Alps over the past 1400 years and finds that extreme precipitation and flooding were less common and less extreme during warm periods compared to cold periods. The authors find “a low flood frequency during the Medieval Warm Period and more frequent and more intense events during the Little Ice Age.” The paper provides yet another example of real-world data disproving climate alarmist (IPCC) contentions that warming results in more extreme weather, extreme precipitation, or floods. The paper also shows that summer temperatures in southwestern Europe were warmer during the Medieval Warming Period [MWP] in comparison to the year 2000, and adds to the work of over 1000 scientists demonstrating that the global MWP was as warm or warmer than the present.


In addition, the paper shows that Total Solar Irradiance sharply increased by about 1 Wm-2 throughout most of the 20th century, dwarfing the alleged effect of CO2 during the 20th century [allegedly about 0.35 Wm-2 per the IPCC formula].

    I have yet to see any scientifically established link between increasing CO2 levels and global temperature increases. The alarmist scare over CO2 is the product of rigged computer models that are tuned to produce a warming signal, i.e. to confirm a pre-ordained conclusion about anthropogenic global warming (AGW).

    Ice core measurements show global temperature increases preceeding increases in CO2, as more of the life-giving gas is released from the oceans and decaying vegetation as the earth warms. Moreover, the radiative absorption properties (in the 15 micron band) is logarithmic, meaning there is less absorption with the addition of each new CO2 molecule. There simply is no proof of CO2-based AGW. During the Ordovician period — a period of extreme cold — CO levels were nearly 10 times current levels. Where was all the warmth?

    The primary drivers of the earth’s climate are all natural: the sun, oceanic oscillations (e.g. PDO, AMO, ENSO) and volcanism. The impact of man-made CO2 (which constitutes a whopping 0.117 percent of the so-called “greenhouse effect”) is the equivalent of a fart in a hurricane.
