What is the relationship of co2 and global atmospheric temperatures

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

We use a newly developed technique that is based on the information flow concept to investigate the causal structure between the global. What I said was this: 'Since the relationship between carbon dioxide increases to model the atmospheric propagation of electromagnetic radiation. . / AAAAAAABJUc/7b67VqPJ2iE/s/global-co2-levels-sincepng. 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.

The more CO2 you add the smaller the outcome. In short, each additional doubling has the same effect on temperature.

The first one does most of the work. You can see the relationship over time in the following graph. The vertical axis shows net downwards forcing, while the horizontal axis shows parts per million of CO2.

The red lines relate the two at the time of the Industrial Revolution conventionallythe green lines show the present, and the black lines the result when the Industrial Revolution level has been doubled. Increased concentrations clearly have a progressively smaller warming effect.

The relationship between CO2 and temperature – DON AITKIN

Although Svante Arrhenius is also credited with it, the first mention I can find for an apparent logarithmic relationship is that of Guy Callendar, an English engineer, in 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. 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. 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.

Rising Global Temperatures and CO2

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. 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.
