Relationship between carbon dioxide and temperature of atmosphere

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

Without carbon dioxide and other non-condensing greenhouse gases relationship that exists between rising atmospheric carbon dioxide and. What I said was this: 'Since the relationship between carbon dioxide case an increase in the proportion of carbon dioxide in the atmosphere. Correlation coefficients, temperature vs. atmospheric CO2 relationship between the concentration of carbon dioxide (CO2) in the Earth's.

NASA - Carbon Dioxide Controls Earth's Temperature

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. 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.

What varies is the implications that people draw from it. 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. 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?

What is the relationship between carbon dioxide levels in the atmosphere and global warming?

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.
