In my last post, I pointed out a problem with the EPA’s major finding that:
Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic GHG [greenhouse gas] concentrations.
I showed that it could be reasonably and straightforwardly argued that less than half of the warming since 1950 contained in the “observed” global temperature history can be attributed to anthropogenic greenhouse gas emissions. This is bad for the EPA, as this finding was simply parroted by the EPA from the IPCC Fourth Assessment Report (AR4)—a report relied on heavily by the EPA in underpinning its Endangerment Finding (that greenhouse gases released by human activities “threaten the public health and welfare of current and future generations.”).
