The picture of global temperature and its drivers as presented by the IPCC and the computer climate models is one in which CO2 has been the dominant factor since the start of the industrial age and other factors have had minimal impact. In order to support this picture, the IPCC has sought to portray CO2 as having been an important driver of global temperature in the past.
The idea that CO2 has been an important driver of global temperature over the last 400,000 years is not supported by the evidence.
The idea that CO2 has been the dominant driver of global temperature over the last 400,000 years is laughable.
It is important to recognise that the formulae used here represent the internal workings of the climate models. There is no “climate denial” here, because the whole series of articles is based on the premise that the climate computer models are correct, using the mid-range ECS of 3.2.

This article is the third in a series of four articles.
Part 1 of the series (Part 1) is here
Part 2 of the series (Part 2) is here
In Part 1, simple mathematical formulae were developed to emulate the carbon dioxide (CO2.) contribution to global temperature change, as represented in the computer climate models.
In Part 2, the formulae were used to have a look at the Medieval Warming Period (MWP) and Little Ice Age (LIA).
Part 3 uses the formulae to have a look at the longer term – at the period used to great effect by Al Gore in his film An Inconvenient Truth.
Note : This article does not say anything new, or claim to find any new results. It has all been said many times before. But by using simple formulae that emulate the internal workings of the…
