I propose we destroy all wetlands. Hey, its a good thing we drive cars around rather than horses/cows/ donkeys etc. Otherwise think of all of the methane! Fart city. I wonder if anyone has correlated localized "global warning" with any festivals like beer-drinking or chili cook-offs. Seriously I think the research on the felled trees and their contribution to global warming is like a zit on the ass of an elephant. It will just go unnoticed in the grand scheme of things. What make this research a real waste? OMFG, they grow back! And perhaps now that a bunch of homes are ruined and people have moved elsewhere, more trees will take their place and absorb even more CO2 fertilizer. Whats even more crazy about this poor science is the fact that by the time these felled trees are fully rotted, young saplings will already be absorbing/scrubbing the air of CO2 at (a wild guess here) a similar rate at which is is being released. Unless of course we decide to turn all of those trees into a parking lot or a series of 1 million mowed lawns instead. Of larger impact is the various large fires around the world this year, which pumped an immediate surge of heat and CO2 into the atmosphere. Still a zit, but a larger one than a bunch of felled trees. However, they will grow back too, and with proper land and forest management, may have a significant effect on removing the CO2 and heat they produced in the near future. Young forests, not mature forests, are the best absorbers of CO2. -LS LS - I don't really know the science on CO2 absorption/emissions and trees. But your comments here are ignoring the whole questions of the 320 million dead and rotting trees giving off methane, aren't you? And isn't methane a greenhouse gas that's some 20 times more potent than CO2? So that the young saplings you're talking about would need to be absorbing about 20 times more CO2 as they grow to maturity as the dead trees will be giving off in methane as they decay? Methane does not exist very long in the atmosphere, it is broken down into CO2 and water via interaction with UV and oxygen. Essentially a slow burn. It does take a while (a lot of factors such as temperature/ pressure/etc), but considerably less time than CO2 can stay in the atmosphere. Well, that doesn't equate well, since CO2 can stick around a very long time, but it does break down quickly. Someone more knowledgeable about the half-life of Methane in the atmosphere could chime in here... It may be in the order of days, not years. It is a decay process however, so dump in a lot of Methane, it takes a lot of time to go back down to 1% of the original amount. When you burn the wood, it just speeds the process considerably. Goes straight from wood to CO2 water and other trace stuff. Keeps my feet toasty. -LS |

Most forest managers with half a skull know that clear-cutting is only a short-term cash cow for "cut and run" a-holes. After that, it takes a long time to get money back from the land again. Selective cutting has a lot less money per harvest year, but over many years, it has a much better net gain. Not only that you have a healthier forest with a much more diverse set of wildlife due to the varying ecosystems and cover provided by the leftover tree tops, you also can grow more wood per acre due to a variety of natural factors. Of course some bozo has to come up with some kind of willow (shrub) that can produce more energy per acre than wood so we may wind up with a lot of mono-culture land like corn in the interest of "saving the world" from ourselves. -LS |

Here we go again I am and you are definitely not I note that Roger does not reply. Chemist, I can't speak for Roger. But speaking for myself, it seems the breadth and scope of your claims about CO2 and methane, which repudiate mainstream science on this subject for the past century or so, suggests that if you're correct in your claims, you're really another Einstein or Galileo figure. Another Copernicus. If your claims are correct, they will rock the scientific world and mark a major shift in how CO2 and methane are understood. Again, I can't speak for Roger, but I'm just not qualified to debate science with another Einstein or another Copernicus. So I don't. Hats off to you if you're one day proven right and are written up in the history books for it, chemist. In the meantime, though, I think most of us will stick with the mainstream view on CO2 and methane as articulated by NOAA, the National Academy of Sciences and the IPCC. The experiments that are supposed to prove that CO2 is a greenhouse gas show that methane is not. It is as simple as that. The American Professor who is responsible for one of the greenhouse gas experiments, the German PhD responsible for another one and Roger Coppock are all unable to offer an explanation for these facts but not one them has called me a liar. (only the tail chewer does that ) |
