The Lewis and Crok exposition – Climate less sensitive to Carbon Dioxide than most models suggest

Full papers plus additional comments from co-author Nic Lewis follow. I have added some relevant diagrams and tables from the report, plus reproduced the foreword by Dr. Judith Curry as well as updated the summary Equilibrium Climate Response Graph originally by Dr. Patrick Michaels to include this new ECS value and range. – Anthony NEW…

CO2 Residence Times, Take Two

Guest essay by Joe Born In a recent post Christopher Monckton identified me as a proponent of the following proposition: The observed decay of bomb-generated atmospheric-carbon-14 concentration does not tell us how fast elevated atmospheric carbon-dioxide levels would subside if we discontinued the elevated emissions that are causing them. He was entirely justified in doing…

Is the Bern Model Non-Physical?

Guest essay by Joe Born Is the Bern Model non-physical? Maybe, but not because it requires the atmosphere to partition its carbon content non-physically. A Bern Model for the response of atmospheric carbon dioxide concentration to anthropogenic emissions is arrived at by adopting the values of , (and maybe ) that make the best fit…

Is Greenpeace facing its Warsawgrad?

Guest opinion by Fred F. Mueller In large-scale wars, there are sometimes prolonged periods of fierce clashes with neither side being able to place the decisive blow that will ultimately tilt the balance in its favor. Then all of a sudden, certain events occur that mark the decisive turning point where one side definitely loses…

On CO2 residence times: The chicken or the egg?

While some model based claims say that CO2 residence times may be thousands of years, a global experiment in measurable CO2 residence time seems to have already been done for us. By Christopher Monckton of Brenchley Is the ~10-year airborne half-life of 14CO2 demonstrated by the bomb-test curve (Fig. 1, and see Professor Gösta Pettersson’s…
