As has been noted by publications across the world, the new IPCC AR5 report confirms that the past catastrophic global warming alarmism, relentlessly pushed by the IPCC community, is essentially without scientific merit.
From the editors of the Nature journal comes this scathing comment about the new report:
"Scientists cannot say with any certainty what rate of warming might be expected, or what effects humanity might want to prepare for, hedge against or avoid at all costs. Despite decades of research funded by taxpayers to the tune of billions of dollars, we are no more certain about the impact of man-made greenhouse gases than we were in 1990, or even in 1979 when the National Academy of Sciences estimated the effect of a doubling of carbon dioxide to be "near 3 degrees C with a probable error of plus or minus 1.5 degrees C."
And of course, there is the amazing admission in the 'AR5' report that those soon-to-be, just-around-the-corner climate disasters, that were repeated ad nausem over the last two decades, are no longer on-the-table, so to speak.
And adding to the IPCC's misery, the latest scientific empirical evidence is not kind. The alarmist hypothesis that human CO2 emissions are similar to a furnace's "thermostat" or a "control-knob" has proven also to be a pseudo-science claim, which actual scientists now consider an embarrassment best forgotten.
Regarding that "thermostat" claim, the above plot of the satellite temperature dataset confirms that even 3-year CO2 changes have apparently zero impact on on 3-year changes. (As previously noted, the last 15 years of global temperature change has revealed a zero impact from changing monthly CO2 levels during that period.)
This chart also includes a plot of human CO2 emissions in gigatons since 1981. Clearly, the gigantic-sized annual emissions are not affecting temperature change, as measured by the satellites. With that said, the exhibited increasing 3-year change of atmospheric CO2 levels may indeed be a result of growing tonnage of human emissions.
In summary, the IPCC's alarmism climate "science" has been torpedoed by its own report and admissions, as well as being completely undermined by the actual empirical evidence. This has not only been recently recognized by the mainstream press, but now the major scientific journals supporting the "consensus" view have finally taken note.
Note: Datasets plotted in this Excel chart can be located here. The temperature and atmospheric CO2 level plots represent 36-month (3-year) changes (e.g. subtract the September 2010 temperature anomaly from the September 2013 anomaly). The dark black, grey and bright red curves are second order polynomial fitted trends produced by Excel - they are not predictions, but they do indicate the current direction the trends are taking.
