Hi Alvia, It is so pathetic, on Friday NSIDC informed that the ice volume had once again shrank to new low. Despite the ice area being bigger than last year, it was only result of more extensive break up and sea ice scattering. The more widely scattered sea ice then absorved more heat from water and melted thinner than ever before. No the ice is becoming paper thin and the latest images show how much the autumn storms are fracturing and scattering this paper thin ice even now.Another twist on story is that the timing of Greenland glaciation has gone tatters, we were aware this since last spring. The Pleiostocene 2-3 myr age has been pushed back to Oligocene 23 myr. We have been questionning the methodology for some time and pushing the Danes to check it out. FIPC think that after the ice-free Arctic Ocean, Greenland ice is melting everywhere on surface extensively and flash floods making that even worse dumping 10-20 cm of rain during electric storms like on the south dome in July 2007. We expect this meltwater fall under ice and it to float on land on its own meltwaters and the ground connectivity loss leading to ice sheet land contaiment failure within a few years of ice-free Arctic Ocean (as referred back to UN General Assembly back in 1992). I would rather correct: "The World Ends in 2020 (at least Greenland ice ends). Are You Prepared?" Rgs, Albert Frozen Isthmuses' Protection Campaign of the Arctic and North Atlantic Oceans
From: [EMAIL PROTECTED]: [EMAIL PROTECTED]: [geo] The World Ends in 2300. Are You Prepared?Date: Mon, 6 Oct 2008 11:36:03 -0400 This paper courtesy of Renaud de Richter, mostly based on a set of models used to assess the impacts of stratospheric aerosols in the year 2300. What about the 21st century? Or didn't the models give the "desired" result for 2100? I note that in Table 2, the global precipitation decrease for 2100 using the AER0 scenario, where temperature is held constant from the year 1900, is only one third that for 2300. I have no problem with worst casing geoengineering, as long as more reasonable and realistic scenarios are also considered or at least mentioned. That doesn't seem to be standard practice, however. And in this piece of research, skipping over 300 years to point out problems could have been part of the study, but it didn't have to be the entire study and is very misleading, especially since it assumes we are still burning coal as a primary power source for electricity production in 2300. >From the summary: "In summary, we have found that climate change mitigation using stratospheric aerosol emissions is associated with high risks which will persist for centuries and even millenia. Therefore, this geoengineering option cannot be seen as a solution to the problem of human-made climate change. Assessment of this option and its consideration as a sort of emergency brake in case climate change becomes too dangerous must not distract the scientific mainstream from searching for sustainable approaches to diminish economic dependence on fossil fuels. There is a long way to go, but this is the only secure way to avoid the high risks of dangerous anthropogenic climate change in the future."_________________________________________________________________ Make a mini you and download it into Windows Live Messenger http://clk.atdmt.com/UKM/go/111354029/direct/01/ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "geoengineering" group.
