His paperread to the Royal Society, is astonishingly modern in its attack, and his simple approach seems to have been ignored by the IPCC.

OK, so where is the rub? The orthodox, including the IPCC, accept that that there is a logarithmic relationship, and that it will produce around 1 degree Celsius for a doubling of CO2. But it is as though they find that quite uninteresting.

The correlation between CO2 and temperature

They are fixated on climate sensitivity, which they see as far more important. Climate sensitivity is the sum of the proposed feedback consequences of a change in forcing — in this case an increase in the proportion of carbon dioxide in the atmosphere. The feedback factors include clouds, water vapour, ice and snow and a few others. The current IPCC view is that the range of multipliers is from 1.

It no longer proposes a midpoint, but the obvious one here is 3. In the IPCC picture, the logarithmic effect of doubling 1 degree C is then multiplied by feedbacks to produce an outcome of between 1.

If the IPCC is right, then my proposed slow change from a doubling, let alone from two doublings, is called into question. But what are the facts? What we have in the literature are estimates based on a great variety of bases.

There are so many, in fact, that the IPCC has abandoned fixing on one of them, or on an average. What is more, there are quite a number of papers that propose a sensitivity that is around 1, and one or two that place it as less than 1.

The way the climate reacts is also complex, and it is difficult to separate the effects of natural changes from man-made ones over short periods of time. As the amount of man-made CO2 goes up, temperatures do not rise at the same rate.

So far, the average global temperature has gone up by about 0. Two-thirds of the warming has occurred sinceat a rate of roughly 0.

Does CO2 always correlate with temperature (and if not, why not?)

Unfortunately, as this quote from NASA demonstrates, anthropogenic climate change is happening very quickly compared to changes that occurred in the past text emboldened for emphasis: In the past century alone, the temperature has climbed 0.

NASA Earth Observatory Small increases in temperature can be hard to measure over short periods, because they can be masked by natural variation. For example, cycles of warming and cooling in the oceans cause temperature changes, but they are hard to separate from small changes in temperature caused by CO2 emissions which occur at the same time.

Tiny particle emissions from burning coal or wood are also being researched, because they may be having a cooling effect. Scientists like to measure changes over long periods so that the effects of short natural variations can be distinguished from the effects of man-made CO2.

At What Temperature Does CO2 Freeze?

The rate of surface warming has slowed in the past decade. Yet the physical properties of CO2 and other greenhouse gases cannot change. The same energy they were re-radiating back to Earth during previous decades must be evident now, subject only to changes in the amount of energy arriving from the sun - and we know that has changed very little.

The answer is into the deep oceans.
