The Climate Sensitivity Dutch Auction

Fitting the data to the theory Story submitted by Eric Worrall A Dutch Action is the reverse of a standard auction – instead of the price starting low, with each bid driving the price up, a Dutch Auction inverts this process – the price starts high, and slowly drops until a bid is placed. The…

The diminishing influence of increasing Carbon Dioxide on temperature

Guest essay by Ed Hoskins Using data published by the IPCC on the diminishing effect of increasing CO2 concentrations and the latest proportional information on global Man-made CO2 emissions, these notes examine the potential for further warming by CO2 emissions up to 1000ppmv and the probable consequences of decarbonisation policies being pursued by Western governments.…

New paper finds transient climate sensitivity to doubling of CO2 is about 1°C

A new paper published in Ecological Modelling finds climate sensitivity to doubled CO2 concentrations is significantly lower than estimates from the IPCC and climate models which “utilize uncertain historical data and make various assumptions about forcings.” The author instead uses a ‘minimal model’ with the fewest possible assumptions and least data uncertainty to derive a…

Ross McKitrick’s presentation to FOS

The Friends of Science 11th annual luncheon was on May 13, 2014, featuring Dr. Ross McKitrick, at the Metropolitan Conference Centre, Calgary, Alberta. In it he says: “Climate models appear to overstate the effects of greenhouse gases.  This presentation will explain the problem and show why it undermines the assumptions behind carbon dioxide emission policies”.…

Climate Sensitivity and Transient Climate Response

Guest essay by Marcel Crok, Climate Dialogue Climate sensitivity is at the heart of the scientific debate on anthropogenic climate change. In the fifth assessment report of the IPCC (AR5) the different lines of evidence were combined to conclude that the Equilibrium Climate Sensitivity (ECS) is likely in the range from 1.5°C to 4.5°C. Unfortunately…
