[A series of articles reviewing the western climate establishment and the media. The first and second discussed air temperatures, the third discussed ocean temperatures, and the fourth discussed past temperatures.]
According to the man-made theory of global warming promoted by the western climate establishment, the recent global warming is due to human emissions of greenhouse gases, which are dominated by carbon dioxide (CO2).
So lets compare the alleged cause (human emissions of CO2) with the alleged effect (temperature).
Human emissions of CO2 have been estimated from historical data for the period 1751 (before the industrial revolution) to 2007 for the major sourcescoal, gas, and petroleum use, cement production, and gas flaringby the Carbon Dioxide Information Analysis Center within the US Department of Energy. (The cumulative figures below extrapolate to 2010 using average annual emissions for the previous 14 years.)
These CO2 emissions figures arent perfect, principally because they omit some causes. The major omission is deforestation, but it is relatively minor:
No one knows what the net effect of deforestation, reforestation, afforestation, and any replacement plants are, even today, let alone in the distant past. It is not even clear what ought to count as a forest emission due to humans, especially when forest and agricultural products are accounted for. In any case, they dont add more than few percent to the DOE emissions figures.
The current global warming trend started before 1700, yet human CO2 emissions were negligible before 1850. So the theory that humans started the recent global warming is absurd and obviously wrong.
Have you ever seen a graph of human CO2 emissions versus temperature (the alleged cause and effect) anywhere in the media or from the climate establishment? Why not?
Why do the climate establishment and mainstream media instead show us graphs of atmospheric CO2 levels versus temperature? Isnt this misdirection to disguise the almost complete non-correlation between our emissions and the temperature?
Perhaps human emissions of CO2 merely aggravated or extended the current global warming trend? Lets zoom in on the era since 1850, when human emissions are significant:
Important admission. Leading member of the climate establishment, Dr. Phil Jones, again: the rates of global warming from 1860-1880, 1910-1940 and 1975-1998:
are similar and not statistically significantly different from each other.
The rates of warming during the warming periods are the same. We know theoretically that CO2 emissions must cause some warming, but that warming does not appear to be large enough to show up in a comparison with temperature.
Nearly all our emissions are quite recent85% of all our emissions ever occurred after 1945, as post-WWII industrialization greatly accelerated emissions:
|Year||Percentage of All Human CO2 Emissions (to 2010) Emitted By That Year|
There has been no significant global warming since 1998 (as Figure 17 shows, and Dr Phil Jones agrees). Yet a quarter of our emissions have occurred since then. If our emissions cause global warming, how come the last 25% of our emissions, concentrated in just 12 years, have not caused further global warming?
