Our planet could warm by as much as 7.2 Fahrenheit degrees by the end of this century if nothing is done to stop or slow the release of greenhouse gases into the atmosphere, according to a study published in the scientific journal Nature.
Cruel Mistress 
Here is a pdf of the invited poster I gave at the Fall AGU meeting in San Francisco, last December (2.9 MB), titled, “Propagation of Error and the Reliability of Global Air Temperature Projections.”
Propagation of error, a standard of the physical sciences, is apparently foreign to climate modeling. It doesn’t exist in the published literature.
Growth of uncertainty from propagation of systematic error shows that when it comes to a purported GHG cause behind recent climate warming, no one knows what they’re talking about.
