Relationship between carbon dioxide and temperature

relationship between carbon dioxide and temperature

As carbon dioxide levels in the atmosphere increase global warming of heat the overall temperature of the Earth is going to have to go up. What I said was this: 'Since the relationship between carbon dioxide increases and temperature is logarithmic it will take a good deal of time to. When the carbon dioxide concentration goes down, temperature goes down. A small part of the correspondence is due to the relationship between temperature .

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.

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

But it is as though they find that quite uninteresting. 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. What is more, the current rate of warming is very small, and we may even be in a cooling phase.

Carbon Dioxide Cannot be the Cause of Global Warming

There's no correlation between CO2 and temperature "Twentieth century global warming did not start until By that time CO2 emissions had already risen from the expanded use of coal that had powered the industrial revolution, and emissions only increased slowly from 3. It was the post war industrialization that caused the rapid rise in global CO2 emissions, but by when this began, the Earth was already in a cooling phase that started around and continued until With 32 years of rapidly increasing global temperatures and only a minor increase in global CO2 emissions, followed by 33 years of slowly cooling global temperatures with rapid increases in global CO2 emissions, it was deceitful for the IPCC to make any claim that CO2 emissions were primarily responsible for observed 20th century global warming.

The amount of CO2 is increasing all the time - we just passed a landmark parts per million concentration of atmospheric CO2, up from around ppm before the industrial revolution. There are several reasons why.

Doubling the amount of CO2 does not double the greenhouse effect. 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. 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.
