MacRae: CO2 not the primary cause of global warming

CARBON DIOXIDE IS NOT THE PRIMARY CAUSE OF GLOBAL WARMING: THE FUTURE CAN NOT CAUSE THE PAST
From a paper by Allan M.R. MacRae, Calgary Alberta Canada

...despite continuing increases in atmospheric CO2, no significant global warming occurred in the last decade, as confirmed by both Surface Temperature and satellite measurements in the Lower Troposphere.

Contrary to IPCC fears of catastrophic anthropogenic global warming, Earth may now be entering another natural cooling trend.

Earth Surface Temperature warmed approximately ("~") 0.7 degrees Celsius ("C") from ~1910 to ~1945, cooled ~0.4 C from ~1945 to ~1975, warmed ~0.6 C from ~1975 to 1997, and has not warmed significantly from 1997 to 2007.

CO2 emissions due to human activity rose gradually from the onset of the Industrial Revolution, reaching ~1 billion tonnes per year (expressed as carbon) by 1945, and then accelerated to ~9 billion tonnes per year by 2007. Since ~1945 when CO2 emissions accelerated, Earth experienced ~22 years of warming, and ~40 years of either cooling or absence of warming.

The IPCC's position that increased CO2 is the primary cause of global warming is not supported by the temperature data.

In fact, strong evidence exists that disproves the IPCC's scientific position.
