sorry, still don't believe in back radiation, there is no evidence to support it.
Ian, sorry for the delay getting to your post. Do you believe that back radiation is absorbed by the surface?
And do you believe back radiation is heat?
What happens when you step outside and the summer sun shines on you?
And if you'd like a little more technical evidence of a DIRECT FUCKING MEASUREMENT OF BACKRADIATION:

P1.7
Measurements of the Radiative Surface Forcing of Climate
W.F.J. Evans, North West Research Associates, Bellevue, WA; and E. Puckrin
The earth's climate system is warmed by 35 C due to the emission of downward infrared radiation by greenhouse gases in the atmosphere (surface radiative forcing) or by the absorption of upward infrared radiation (radiative trapping). Increases in this emission/absorption are the driving force behind global warming. Climate models predict that the release of greenhouse gases into the atmosphere has altered the radiative energy balance at the earth's surface by several percent by increasing the greenhouse radiation from the atmosphere. With measurements at high spectral resolution, this increase can be quantitatively attributed to each of several anthropogenic gases. Radiance spectra of the greenhouse radiation from the atmosphere have been measured at ground level from several Canadian sites using FTIR spectroscopy at high resolution. The forcing radiative fluxes from CFC11, CFC12, CCl4, HNO3, O3, N2O, CH4, CO and CO2 have been quantitatively determined over a range of seasons. The contributions from stratospheric ozone and tropospheric ozone are separated by our measurement techniques. A comparison between our measurements of surface forcing emission and measurements of radiative trapping absorption from the IMG satellite instrument shows reasonable agreement. The experimental fluxes are simulated well by the FASCOD3 radiation code. This code has been used to calculate the model predicted increase in surface radiative forcing since 1850 to be 2.55 W/m2. In comparison, an ensemble summary of our measurements indicates that an energy flux imbalance of 3.5 W/m2 has been created by anthropogenic emissions of greenhouse gases since 1850. This experimental data should effectively end the argument by skeptics that no experimental evidence exists for the connection between greenhouse gas increases in the atmosphere and global warming.
This is the fourth time - at least - that Evans 2006 has been posted. Where do you get the fucking cojones to claim there's no evidence to support back radiation?
Frank, JC, why do you think this post is funny? It makes you look like fools.
Because you think it says the last 2PPM of CO2 added to the atmosphere are causing earthquakes and heating the oceans 700m down, that's what's funny
