Roy Spencer with John Stossel

“To shut down CO₂ is to shut down civilisation.”

Piers Corbyn: the Sun Warms the Earth, and How

To say that CO₂ drives global warming, “is utter madness, and fraud”.
“We are heading for a Dalton-type minimum of cold temperatures which will affect Europe considerably: there will be more very cold winters and more lousy summers.”

Greenhouse Theory Melts Away

UPDATE II (17 March): see “What The ‘Skeptics’ Of Climate Catastrophe Are Skeptical Of:  Nordhaus Reconsidered”, by Eric Dennis:

The most frustrating thing about being a scientist skeptical of catastrophic global warming is that the other side is continually distorting what I am skeptical of.  [...]
The object of our skepticism, catastrophic global warming, means warming caused by greenhouse gasses that would so dramatically heat up the earth that despite the proven climate adaptability of hydrocarbon-powered civilization [...], populations the world over would experience impoverishment, mass suffering, and death.
Why are we skeptical of this claim?  Because there is radically insufficient evidence for it.
This may seem implausible, because the news media bombard us with stories of new studies, new findings, new models, new international summits allegedly confirming catastrophic global warming.  But what these stories leave out is the evidential status of these developments—what any given study or model actually proves.  And the answer is, little to nothing, because the present ability of scientists to understand, model, and predict the climate is far, far lower than we are led to believe.
