Saving The Appearances Goes On Without Pause
Roy Spencer has a recent post suggesting a way that "deep ocean warming can bypass the surface" (for those trying to explain the "pause" in global mean surface temperature, without admitting their basic theory has been proven wrong by that "pause"). My response:
The comparison of temperatures in the atmospheres of Venus and Earth, at points of equal pressure over the range of Earth tropospheric pressures, shows that the Venus/Earth temperature ratio is precisely explained by the different solar distances of the two planets and nothing else. This proves there is no increase of temperature with increasing CO2, since Venus has 96.5% CO2 to Earth's .04%. And the comparison was done using temperature and pressure profiles obtained for Venus on one day (October 5, 1991, a long time ago now), compared with the same profiles as defined in the Earth Standard Atmosphere--so the comparison confirms the validity of the Standard Atmosphere as the real equilibrium state of Earth's troposphere, and as such, independent of any supposed changes in ocean heat content. And finally, since Venus and Earth differ so fundamentally in albedo, cloud cover, and planetary surface, the fact that their atmospheric temperature ratio is just precisely that expected from their different solar distances alone, tells any good physicist immediately (I realized it while writing my original posting, in November 2010, from one sentence to the next) that the troposphere is warmed, on the global scale, entirely by direct absorption of incident solar radiation (or radiation higher in the atmosphere), and not at all from the surface as today's academics universally believe and promulgate--so changes in the ocean heat content are irrelevant to the global mean surface temperature (just as it makes no difference that Venus's surface is all solid crust, while Earth's is 71% ocean). Climate scientists are, in my view, obviously chasing local and transient (and near-surface) effects--also called weather--and not global ones. All of this should have been learned and accepted years ago (as far back as 1979, when the first Venus data was obtained, which agreed with the 1991 data I used in my comparison). Empty speculation (such as that done by believers in the greenhouse effect) in order to "save the appearances" has a long history, and it is never good. The sooner the wider scientific community confronts and accepts the Venus/Earth comparison and the confirmation of an utterly stable, overarching equilibrium as the predominant reality in our atmosphere, the better for all of science (for every other earth and life science is also in need of fundamental rethinking, I assure you).
