Unfortunately I was unable to find anything therein that can be described as, "actual measurement of the climate forcing by CO2 and other greenhouse gases." Might I have missed it? Maybe you could be so kind as to cut and paste something from the text that specifically substantiates this assertion? Thanks in advance for your response.

Top of page The evolution of the Earth's climate has been extensively studied1, 2, and a strong link between increases in surface temperatures and greenhouse gases has been established3, 4. But this relationship is complicated by several feedback processesmost importantly the hydrological cyclethat are not well understood5, 6, 7. Changes in the Earth's greenhouse effect can be detected from variations in the spectrum of outgoing longwave radiation8, 9, 10, which is a measure of how the Earth cools to space and carries the imprint of the gases that are responsible for the greenhouse effect11, 12, 13. Here we analyse the difference between the spectra of the outgoing longwave radiation of the Earth as measured by orbiting spacecraft in 1970 and 1997. We find differences in the spectra that point to long-term changes in atmospheric CH4, CO2 and O3 as well as CFC-11 and CFC-12. Our results provide direct experimental evidence for a significant increase in the Earth's greenhouse effect that is consistent with concerns over radiative forcing of climate.

The title that you supplied here specifically refers to inference, not measurement. Possibly you have mistakenly considered inference and measurement to be interchangeable terms. I assure you they are not. Would you now like to make a retraction of your claim regarding, " . . . actual measurement of the climate forcing by CO2 and other greenhouse gases?" All things considered I think it would be best if you did. > > John E. Harries, Helen E. Brindley, Pretty J.

You seem to have trouble with the basic science. I expected many people on this forum would, that is why I included the following link in my original post: To get a grip on global warming science, Here are some lectures recorded in a classroom at a world class university: http://www.youtube.com/view_play_list?p=FA75A0DDB89ACCD7 On Aug 1, 1:58 pm, Claudius Denk <claudiusd...(a)sbcglobal.net> wrote: > On Aug 1, 1:33 pm, Roger Coppock <rcopp...(a)adnc.com> wrote: > > > On Aug 1, 1:21 pm, Claudius Denk <claudiusd...(a)sbcglobal.net> wrote: > > > > On Aug 1, 1:16 pm, Roger Coppock <rcopp...(a)adnc.com> wrote: > > > > > An actual measurement of the climate forcing by > > > > CO2 and other greenhouse gases, and an estimate > > > > of the growth of that forcing over time. > > > > >http://www.nature.com/nature/journal/v410/n6826/abs/410355a0.html > > > > I read your link thoroughly.
