Sorry Grommit, but after quite careful perusal of all your links, some of which are quite detailed, all I can ascertain is that there is good evidence that atmospheric CO2 has risen, in fits and starts and that some temperatures have risen without much direct correlation to the observed CO2 levels. Generally however both have increased at least until last year when temperatures seem to have dropped without any real changes in CO2.
However not a single one of all of the links quotes, references or demonstrates any good experimental data or specific measurements that link atmospheric CO2 concentrations to atmospheric temperature changes. There are not even any decent lab studies that test that hypothesis. If I have missed one please point out the specific study.
CO2 does absorb heat in the form of infrared radiation peaking at 14 micrometers. It absorbs virtually nothing at a longer wavelength. This is recognised science demonstrated by actual experiments. The present levels of CO2 already absorb virtually all the energy at that wavelength. Increasing the level of CO2 therefore will have virtually no effect. This fact alone negates the whole argument that increase of man made CO2 will make any difference to the temperature of the earth, and makes all carbon taxes, sequestrations, reductions of emissions of CO2 a complete waste of time, money and resources.

All your reference are based on the "truism" that rising CO2 levels "must" cause linear rises in atmospheric temperatures without a single shred of evidence to support that. In fact the basic science directly refutes it. When their extrapolations start to get shaky they start adding in methane, water vapour and other odd gasses as "CO2 equivalents" to support their assumptions. While these other gases certainly have effects, directing action at CO2 emissions is completely pointless if it is not the actual cause.
That global temperatures have risen over a very geologically short period is not the question. That CO2 levels are rising is also not in question. What is in question is whether there is any real linkage between the two and even if there is which is the cause and which is the effect?
Every study that commences with the premise that increasing CO2 level in the atmosphere causes significant temperature rises is, in my opinion, based on faulty science and because of that it will always produce a faulty result. |
