He showed us how heat was felt on skin as we stood well back; Unlike hydrogen like when the Hindenburg, a great Zeppelin burnt up in NJ where heat didn't radiate back like that. He explained this was because carbon was not in H2 gas that made Zeppelins fly. What's happening in sky at high altitude I'd imagine is on same order able of being felt..<br />Something to avoid at all cost in my estimation..Dale Lananhttps://www.blogger.com/profile/05409842680440987251noreply@blogger.comtag:blogger.com,1999:blog-3046701423623795423.post-18068752798856046552012-10-16T01:46:27.415-07:002012-10-16T01:46:27.415-07:00Good points, Mike, I agree that the preindustrial ...Good points, Mike, I agree that the preindustrial methane level of about 0.7 ppm should be a safe target. I often say that, on a mass-to-mass basis, methane is 105 times as potent as carbon dioxide over 20 years and even more potent over a shorter period, as described in <a href="http://arctic-news.blogspot.com.au/2012/05/video-and-poster-methane-in-arctic.html" rel="nofollow">Methane in the Arctic</a>. Methane's potency as a greenhouse gas underlines both the need to reduce global methane emissions and the need to avoid further emissions (as are threatening to occur in the Arctic), as well as the need to work on methods such as decomposition as described in the post.

1...Just a couple of things on the opening numbers:<br /><br />1. Global warming potential (GWP) is calculated on a per unit mass of emission basis (and it is mass of the gas, so of CO2 and CH4), whereas the atmospheric concentrations are in parts per million by volume (so number of molecules per million molecules of air). To make that correction, since methane has a molecular weight of 16 and CO2 is 44, one needs to multiply the GWP of methane by 44/16 to use it as a multiplier to get the equivalent effect of a methane concentration in terms of CO2. So, that makes the problem of methane worse than you suggest.<br />2. In your multiplying, you use a methane concentration of 2 ppm. The problem here is the baseline needs to be subtracted off if you are going to do a comparison of human influences. The preindustrial baseline was about 0.7 ppm, and the present global value is about 1.8 ppm, so the human increment is about 1.1 ppm, not 2. So, this reduces the human influence, though not the overall methane influence, but it would be very hard to get the global concentration of methane back to zero.<br /><br />Together, the rising methane concentration is indeed a problem--this is all just some fine tuning of the analysis.Anonymoushttps://www.blogger.com/profile/06423206958360648447noreply@blogger.comtag:blogger.com,1999:blog-3046701423623795423.post-13721718568226162382012-10-14T16:21:15.167-07:002012-10-14T16:21:15.167-07:00Energy needs depend on the concentration of methan...Energy needs depend on the concentration of methane in the targeted area, and on the levels the methane is to be brought down to in the respective area. Energy produced at night at offshore wind turbines could be used to power the necessary facilities. In that way, such 'enhanced methane decomposition' methods go hand in hand with clean energy projects, as also discussed <a href="http://methane-hydrates.blogspot.com/2012/03/large-areas-of-open-ocean-starved-of.html" rel="nofollow">in this post</a>. A lot of testing is needed and such tests should bring up further answers as well as further questions, which is a good thing, it will bring about a lot of jobs and investment opportunities in clean technologies.Sam Caranahttps://www.blogger.com/profile/12376449209858411775noreply@blogger.comtag:blogger.com,1999:blog-3046701423623795423.post-15108649617203633832012-10-14T05:59:10.265-07:002012-10-14T05:59:10.265-07:00How much energy will it take to get side band freq...How much energy will it take to get side band frequency disturbance upon CH4 concentrated for effect and wouldn't infrastructure mean jobs creation like crazy once go ahead decision is made? CH4 once released is like a veil of an electric heating blanket wrapped around Earth stuck on high with jump of voltage going up, up. I don't think people grasp urgency of heat increasing force of CH4 or job opened to counter.Dale Lananhttps://www.blogger.com/profile/05409842680440987251noreply@blogger.com
