The WoodforTrees Chart below shows no Global warming since 1997 to date. The data used to construct the chart came from Hadley Center and University of East Anglia’s Climate Research Unit—yes this is the CRU of Climategate fame.
(click on charts for clarity.)
During this period, carbon dioxide (CO2) has increased from about 362 ppm in 1997 to 396ppm by mid-year 2012. (See atmospheric CO2 chart below.) If CO2 is the potent forcing agent claimed by the proponents of the man-made global warming theory, then why are the global temperatures flat? 15 years of no statistically significant global temperature increase are in the books. When is enough, enough. Last I heard, the warmers had lengthened the needed time to 17 years. Want to bet that when 17 years arrives and the temperature shows no increase, that they will want to lengthen the time needed, once again.
This posting is not to deny that for 10,000 years or so the globe has been warming. Rather it is to demonstrate that no one really has proven the cause to be other than “natural”.
Do you hear a chorus of “cherrypicking” from the warmers? Please note that their CO2 theory was postulated during a period of rising global temperatures and a corresponding atmospheric CO2 increase. We said then, about their theory, that correlation does not prove causation. And we were right. 15 years of no correlation proves no causation.
