Re: Recent methane spikes in the arctic

Oh well, he was only off by a factor of a thousand. The business as usual position seemingly seeks to ignore this kind of data. If Mr. Beckwith is correct and civilization will collapse in less than 10 years due to catastrophic climate change then business as usual would be the rational response; it's far far too late to reverse the trend now so lets enjoy the little time we have left. But is Mr. Beckwith correct? Beckwith seems to base his apocalyptic prediction from data provided by Natalia Shakhova, she made a measurement of methane at 8000 parts per billion (not million), but Patrick Crill was on a Swedish icebreaker at the same time and at almost the same place and was also taking methane measurements and he only saw about a quarter as much methane. So either the methane release was very localized or somebody made a mistaken measurement. And it's true that methane is a powerful greenhouse gas, but unlike CO2 methane breaks down in the atmosphere in just a few years so to have a strong effect on the climate you'd need to release the methane rapidly and continuously for a long time. Thanks to Greenland's ice we have a record of Earth's atmosphere going back hundreds of thousands of years, and we know that during the interglacial period 125,000 years age the arctic got a lot warmer very quickly, but the methane in the air increased only slightly, nothing like the dramatic increase Beckwith is predicting. But why doesn't the increasing temperature melt the methane hydrates and rapidly release lots of methane and cause a disastrous positive feedback effect? Because methane hydrates can only form hundreds of meters below the arctic sea floor and it would take thousands of years for the surface heat to get down that low. Beckwith, like most environmentalists, is a fear monger. Shortly after the huge Joplin Missouri tornado in 2011 Beckwith said: In our “new climate” (in which there is much less sea ice in the Arctic) this type of tornado [EF-5 the strongest type] will be much more probable Well take a look at chart showing the number of EF-5 tornado since 1950 and you tell me if we should panic.

Re: Recent methane spikes in the arctic
The business as usual position seemingly seeks to ignore this kind of data. After all it is rather inconvenient for the position that they hold that: either no warming is going on; or else all measured warming is just the result of some hypothetical mysterious natural cycle that has little to do with industrial era emissions.And if all of that fails then to the fall back position of warming... it is good for the planet.
