Comment on Argument and authority in the climate fight by Girma

In science, when the observation does not match theory, we chuck the theory.

Here is comparison of Anthropogenic Global Warming (AGW) theory and observation:

IPCC AR4, 2007 => http://bit.ly/z7cOHe

This comparison shows the observed global mean temperatures (GMT) are less than model projections if human CO2 emission were held constant at the 2000 level.

In addition, there has not been any change in the climate as there has been only a single GMT pattern since record begun 160 years ago. This pattern has a unique property of a warming trend of only 0.06 deg C per decade and an oscillation of 0.5 deg C every 30 years. This pattern can be clearly observed in the data from NASA and the University of East Anglia as shown in the following graph.

This result shows, for 160 years, the GMT pattern (the climate) has not been affected by human CO2 emission, volcanoes and aerosols! These variables did not have effect because the GMT pattern before and after mid-20th century were nearly identical.

As observations do not match AGW theory, chuck the AGW theory!
