On Sunday, the London Telegraph previewed a new report from the UN Intergovernmental Panel on Climate Change, which is viewed as an authoritative source of global warming science.
According to the Telegraph, the report concludes “there can be little doubt that humans are responsible for warming the planet.” Moreover, carbon dioxide emissions are accelerating and the IPCC predicts “that temperatures will rise by up to 4.5 C during the next 100 years, bringing more frequent heat waves and storms.”
The IPCC also “lowered predictions of how much sea levels will rise in comparison with its last report in 2001.” The new estimate was “a refinement due to better data on how climate works rather than a reduction in the risk posed by global warming.”
Sen. James Inhofe (R-OK), outgoing chairman of the Environment & Public Works Committee, said the report is evidence that global warming was all hype:
We are all skeptics now. It appears that the UN is now acknowledging what an increasing number of scientists who study the climate have come to realize: Predictions of manmade catastrophic global warming are simply unsustainable.
Inhofe’s core claim is that global warming is “the greatest hoax ever perpetrated on the American people” and humans are not responsible for climate change. The new IPCC report does not support Inhofe’s position, it undermines it.
It’s ironic that Inhofe is now citing the IPCC as an authority. In speech on the Senate floor in 2003, Inhofe claimed that “the IPCC process resembled a Soviet-style trial, in which the facts are predetermined, and ideological purity trumps technical and scientific rigor.”
