Dude, Where’s My Consensus?

IF mankind’s emissions of CO2 are (as claimed) driving un-natural, “dangerous” global warming, then the earth’s climate system’s degree of sensitivity to CO2 is clearly a critical piece of knowledge.

If you don’t first know how sensitive the climate is to CO2, then you can hardly be credible if you try to claim that any particular source of CO2 (like, say, man) is having an effect on the climate.

So, just how sensitive is the earth’s climate system to CO2?

Buried in a footnote (16) to the UN IPCC’s 5th Assessment Report, Summary for Policy Makers, we learn that …

“No best estimate for equilibrium climate sensitivity can now be given because of a lack of agreement on values across assessed lines of evidence and studies.”

Er … no best estimate for the climate’s sensitivity to CO2 can be given?

Because of a “lack of agreement”?

But I thought “the science is settled”?

Dude, where’s my “consensus”?

    If anyone should know anything about CO2 and the Earths atmospheric sensitivity to it then it must be NASA.
    .
    In 1994 Dr. Daniel Goldin was the Administrator of NASA and is referred to on page 459 of “DARK MOON – Apollo and the whistleblowers” by Mary Bennett and David S. Percy.
    .
    Quote: “……Dr. Goldin then returned to the subject of manned space stations in LEO and emphasised the studies that needed to be made concerning our own planet. Thus enrolling the “let’s invest the NASA Budget in our planet” environmentalists. To this end he specifically cited the proposed examination of the sources and sinks of carbon dioxide around the Earth…….”
