The Punch

Having arranged the Newcastle leg of Lord Monckton’s Australian tour and listened to his exposition of the failings of the Intergovernmental Panel for Climate Change [IPCC] science it astounds me that carbon dioxide is still being described as a pollutant by the increasingly shrill advocates of anthropogenic global warming [AGW].

Ridiculing Lord Monckton avoids the dubious science behind climate change.Ridiculing Lord Monckton avoids the dubious science behind climate change.

As well as the litany of mistakes, subterfuges and potential corruption by the IPCC two new peer reviewed papers show that the carbon cycle has only negligible sensitivity to temperature change [Frank et al, 2009 Nature 463] and that the human emissions of CO2 have negligible effect on the climate as measured by the fraction of human emissions of CO2 staying in the atmosphere which has not changed since 1850 [Knorr, W; 2009 GRL 36]

The American Environmental Protection Agency [EPA] has recently declared Carbon Dioxide is a poison ranking it up there with arsenic and nitrous oxide.

This effectively by-passes the need for President Obama to negotiate any emissions trading scheme through the US congress, because with Carbon Dioxide officially a poison regulations can be made limiting and controlling emissions without recourse to the Congress.

In Australia green groups like Beyond Zero Emissions want to reduce atmospheric concentrations of Carbon Dioxide to levels that existed before the industrial revolution.

All this demonization of Carbon Dioxide is occurring with doubt about whether human activity is entirely or partially responsible for the increase in atmospheric carbon dioxide levels.

The connection between levels of carbon Dioxide and climate is also problematic, but most importantly there has been no attempt made by the proponents of man-made global warming [AGW] to consider how important Carbon Dioxide is for human survival.

In a seminal study in 1995 professor Rowan Sage considered the development of agriculture and the role increased levels of Carbon Dioxide played in that development. According to Sage agriculture began about 12000 years ago at a time when the level of carbon dioxide increased from 200 parts per million [ppm] to 270ppm.

Atmospheric Carbon Dioxide levels directly affect photosynthesis and plant productivity generally but at levels above 200ppm the benefit to what are known as C3 plants, which include all the major food crops, is proportionally greater and allows these plant types to compete against C4 plants which include weeds and other non-editable plant types. At levels below 200ppm plants of any type cannot grow.
