Physicist's view of global warming

When UC Berkeley physicist Richard Muller asks his students if they have experienced global warming, most of the undergraduates say they have.

Which is curious, Muller said Monday at Sonoma State University, because for the past 10 years the globe has not gotten any warmer...

He personally subscribes to the Intergovernmental Panel on Climate Change, or IPCC, finding that it is "very likely" humans caused some of the 1 degree Fahrenheit global temperature increase in the past 50 years.

Dissenter: CSIRO Scientist calls man-made climate fears a 'deceptive delusion' [PDF]

In summary, I have yet to see credible proof of carbon dioxide driving climate change, yet alone man-made CO2 driving it. The atmospheric hot-spot is missing and the ice core data refute this. When will we collectively awake from this deceptive delusion? [...] I contend that those professional scientists and advisors that are knowingly complicit in climate science fraud and all that is derived from it, will continue to be exposed by the science itself. [...] There is no atmospheric hot-spot from "greenhouse CO2" despite over 20 years of serious looking for it (read Dr Evans and Dr Spencer's recent media and US Senate evidence statements). Occam's razor would point to the sun as the driver of climate change of significance. Human generated carbon dioxide is arguably around 3% of the total carbon dioxide budget, and in the light of the above, we are effectively irrelevant to the natural climate change continuum.
