REALITY PROVES IPCC WRONG : C02 NOT A PROBLEM
MAN-MADE GLOBAL WARMING IS A MYTH
The evidence, as published by 3 of the 4 recognized world temperature data recorders**, is the following: there has been no warming since 1998, and in 2008 we are witnessing significant cooling. Sea ice covers the usual area in both the Arctic and the Antarctic; Atlantic and Pacific currents are both in their cooling cycle; and there are no spots on the sun, which has some scientists suggest we may be entering a "little ice age".

Now is the time to take another look at the role of anthropogenic C02 in the evolution of climate. Allan MacRae gives us the facts.

The evidence to date suggests that increased atmospheric CO2 plays NO significant role in causing global warming.
The best data shows no significant warming since ~1940. The lack of significant warming is evident in UAH Lower Troposphere temperature data from ~1980 to end April 2008, and Hadcrut3 Surface Temperature data from ~1940 to ~1980.

Above chart: Surface Temperature is influenced by other factors such as the Urban Island Heat Effect, and the location of temperature recording stations, which suburbia tends to encircle over time with its heat-retaining asphalt and concrete. The global cooling from approximately 1946-1977 coincides with the cool phase of a natural cycle called the Pacific Decadal Oscillation (PDO), and the warming from approximately 1977-2007 coincides with the warming phase of the PDO. NASA announced in 2008 that the PDO has again shifted to its cool phase. Significant cooling was experienced in 2007-2008, and is expected to continue.
Furthermore, it is clear that CO2 lags temperature at all measured time scales, from ice core data spanning thousands of years to sub-decadal trends - the latter as stated in my paper**, and previously by Kuo (1990) and Keeling (1995) .
** My paper
In late November 2007 Pieter Tans** described the close relationship between dCO2/dt and temperature, about one month before I made a similar finding. This is a further step forward in our understanding.
** Tans´ paper
Above Figure 3 from MacRae´s January 2008 paper shows the close relationship between dCO2/dt and temperature, and the approximate 9 month lag of CO2 after temperature.
Finally, human-made CO2 emissions have increased almost 800% since 1940.
CO2 data from CDIAC
This data consistently suggests that the sensitivity of global temperature to increased atmospheric CO2 is near-zero, and thus there is no human-made catastrophic global warming crisis.
Update: The UAH LT global average temperature anomaly dropped another 0.2C in May 2008.
