EARTH'S TEMPERATURE IS A BIT UP AT THE MOMENT BUT THAT STARTED WAY BACK

"In a study of lichens of the subspecies Rhizocarpon geographicum found on avalanche boulder tongues in the eastern part of the Massif des Ecrins of the French Alps (45ø00' S, 6ø30' E), Jomelli and Pech (2004) make an important discovery that adds to the growing body of evidence which demonstrates that what climate alarmists call the unprecedented and CO2-induced warming of the 20th century was neither unprecedented nor driven by rising CO2 concentrations.

According to the findings of Jomelli and Pech, high-altitude avalanche activity during the Little Ice Age (LIA) reached an early maximum prior to 1650, after which it decreased until about 1730, whereupon it increased once again, reaching what was likely its greatest maximum about 1830. In support of these findings, Jomelli and Pech note that "a greater quantity of snow mobilized by avalanches during the LIA can be supported by the fact that the two periods, AD1600-1650 and 1830, during which the run-out distances [of the avalanches] were maximum at high elevation sites, have corresponded overall to the periods of maximum glacial advances for these last 500 years (Le Roy Ladurie, 1983; Reynaud, 2001)."....

In contrast to these observations, the infamous temperature history of Mann et al. (1998, 1999) -- which is cited by climate-alarmists as justification for the ungodly warming power they attribute to anthropogenic CO2 emissions -- post-Little Ice Age warming did not begin until about 1910. Consequently, it can be appreciated that (1) perhaps half of the warming experienced by the earth in recovering from what was likely the coldest part of the Little Ice Age occurred well before the Mann et al. temperature history indicates any warming at all, that (2) an even greater part of the total warming occurred before the air's CO2 concentration began increasing in earnest (approximately 1930, which is actually close to the time when warming peaked in the United States and many other parts of the world), and that (3) the lion's share of the warming of the past nearly two centuries must therefore owe its existence to something other than rising atmospheric CO2 concentrations."

Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is to promote themselves as wiser and better than everyone else, truth regardless.
