Climate Change Authority: Last Spasm
by Anthony Cox
The government has already abolished the Climate Commission and Flannery is off romancing the new lady in his life, ex-prostitute, Kate Holden. Now it is the turn of that equally pompous and irredeemably incompetent Climate Change Authority [CCA] which will soon be abolished by the practical Abbott government.
None the less the CCA has managed to squeeze out one last report about the dire need to reduce our CO2 emissions due to man-made global warming [AGW]. The report is a farrago, an absolute mishmash of unrelenting garbage.
The basis of all its recommendations about increasing renewables and reducing CO2 emissions is Chapter 2, which deals with the ‘Science’ supporting [sic] AGW. Nothing in this chapter is correct; it is misleading from go to woe. Some examples demonstrate this.
On page 2 of Chapter 2 the Report says CO2 is the most important Greenhouse gas [GHG] and is produced in large quantities by humans.
CO2 is not the most important GHG, H2O is. This is beyond dispute despite bizarre ‘consensus’ papers produced on behalf of AGW which purport to show CO2 is a control knob for climate [see point 8 here.].
But there is no question that H2O is at least 2.5 times as important as CO2 in trapping and reemitting radiation as the Report quaintly and erroneously explains. The greater importance of H20 is clearly shown in this table prepared by one the greatest of all climate scientists, Ramanathan:
As is plain when H20 is removed there is a 25% adjustment on radiation flux; whereas when CO2 is removed there is a 9% adjustment. That is at the top of the atmosphere.
The difference within the atmosphere is even more marked. This is illustrated in the famous schematic cartoon prepared for AGW science purporting to show the movement of radiation within the atmosphere by Keihl and Trenberth [K&T]:
