I am not ignoring the re-emission of energy but you seem to want to ignore its re-absorbtion by other CO2 (and other GHG)molecules. You also want to ignore the transfer of kinetic energy (conduction) to non-GHGs molecules.
But when you try to ignore the speed at which CO2 re-emits energy in order to try and change the subject to kinetic energy instead of radiation energy
When you will not answer a question which is highly relevant to your position...
when you pick and choose relevance based not on numbers but on which is beneficial to your argument...
well, thank you for the debate.
The heat is radiated back into space. If a 15 um wavelength of that heat meets up with a molecule of CO2 (or water vapor) it will be absorbed and re-emitted in a random direction. That's a 50% probability that it will return to earth (assuming a low enough altitude for the planet to be considered a plane... just to take care of any nit-pickers) and add to the heat received.
“Earlier we found torch-like structures like this but they were only tens of metres in diameter. This is the first time that we’ve found continuous, powerful and impressive seeping structures, more than 1,000 metres in diameter. It’s amazing,” Dr Semiletov said. “I was most impressed by the sheer scale and high density of the plumes. Over a relatively small area we found more than 100, but over a wider area there should be thousands of them.”
Scientists estimate that there are hundreds of millions of tonnes of methane gas locked away beneath the Arctic permafrost, which extends from the mainland into the seabed of the relatively shallow sea of the East Siberian Arctic Shelf. One of the greatest fears is that with the disappearance of the Arctic sea-ice in summer, and rapidly rising temperatures across the entire region, which are already melting the Siberian permafrost, the trapped methane could be suddenly released into the atmosphere leading to rapid and severe climate change.
Dr Semiletov’s team published a study in 2010 estimating that the methane emissions from this region were about eight million tonnes a year, but the latest expedition suggests this is a significant underestimate of the phenomenon.
I am talking about absorption of energy, not gasses.
Just curious at the response on reabsorption of the gases. Are you suggesting it may not be as bad as some predict? Because that would be good, yet would it not lend to other problems?
Last July, a record melting occurred on the Greenland ice sheet. Even in some of the highest and coldest areas, field parties observed rainfall with air temperatures several degrees above the freezing point. A month before, it was as though Greenland expert Jason Box had a crystal ball; he predicted this complete surface melting in a scientific publication. Box's research then got broader public visibility after climate activist and writer Bill McKibben covered it in Rolling Stone magazine.
The basic premise of Box's study was that observations reveal a progressive darkening of Greenland ice. Darkening causes the white snow surface to absorb more sunlight which in turn increases melting. Given that this process is likely to continue, the impact on Greenland melt, and subsequent sea level rise, will be profound.
Arctic sea ice, another key measure of global heating, is now 60 years ahead of worst-case projections from the last report by the Intergovernmental Panel on Climate Change in 2007. Arctic snow cover on land has also been declining more rapidly than projected, even faster than sea ice. While mass loss of the enormous Greenland sheet is difficult to measure, satellite data indicate it has doubled in the last decade. If this acceleration continues, sea level rise could be even higher this century than the 1 or 2 meters that mainstream scientists now project – possibly much higher.
