The global warming hysteria and panic that inflicts the intelligentsia ranks of leftists/liberals reveals not only their incredible climate stupidity, but also their total disdain for scientific evidence. The utter contempt that progressives and socialists hold for the scientific process, and the tax-paying public, has been on crude display to the entire world as the "elites" amazingly try to claim that global cooling and snow/ice conditions are now miraculously the result of CO2-induced global warming. The scam flip-flop of left-liberal climate science is simply stunning.
Regardless of this non-scientific cooling flip-flop, the primary claim of Democrat politicians, the left-biased MSM and government funded climate scientists remains the same: that recent global warming temperature change is "unprecedented." As the below chart depicts though, recent annual temperature changes reported by the NOAA/NCDC dataset are well within normal variability. And as an additional smackdown of the elites' science of stupidity, levels of CO2 show little, if any, impact on actual global temperature change. (click on images to enlarge)
Despite the leftist-liberal war-on-science public relations effort to convince the public that global warming is a modern phenomenon, the globe has been warming for approximately the last 200+ years since the end of the Little Ice Age, prior to large industrial/consumer CO2 emissions. This inconvenient science for the left has been thoroughly researched and documented in the peer-reviewed science journals. This next chart represents global temperatures since 1880; the minor warming trend (0.57 per century) over that time; the indicated 2100 temperature level (blue dots) if this 130-year trend continues; the non-reality based left-liberal prediction of 2100 temperature level (red squares); and, the corresponding atmospheric CO2 levels (black dots).
Clearly, the empirical evidence does not support any of the claims and predictions of runaway temperatures or "tipping point" warming that big-government, big-tax Democrats and the MSM religiously propagandize.
The hysterical and ludicrous claims of scary global temperature increases made by the left-liberal elite society is completely exposed as a Madoff-sized scam when the NOAA/NCDC temperature dataset is analyzed for the most recent 10-years. Talk to any liberal-progressive (or read/listen to the liberal-biased MSM sources) and they will categorically lie by stating that global temperature warming has been "accelerating" over the last decade, which will result in catastrophic 'gloom & doom' temperatures by 2020, 2050 and 2100. As the official government climate data source documents, the claim of "accelerating" temperatures is totally contradicted by the actual scientific empirical evidence, as this last chart shows.
Instead of global temperatures "accelerating" due to increased human CO2 emissions, global temperature warming has actually decelerated and is now approaching a zero per century trend as the above chart indicates. There is a strong likelihood that by the end of 2011 an overall global cooling trend will develop, which will add to the total invalidation of the myopic, CO2-centric AGW theory that liberals-progressives-socialists have wasted literally billions of taxpayer dollars on.
Unfortunately for Democrats and elites, their war-on-science and the American taxpayer has been hoisted on the petard of actual scientific evidence. The left's catastrophic man-made warming propaganda has been embarrassingly castrated by the real deal - it's called empirical data.
