Re: [geo] More on Arctic methane

2013-07-31 Thread Emily L-B
Hi thanks. Is the point here, that given warming, there is no currently known natural mechanism to prevent methane release? Therefore we must prevent release - even if this means using an anthropogenic mechanism? With my best wishes to everyone trying to sound the alarm and diffuse the bomb.

Hi helping to moderate temperature spikes could help corals buy time while co2 levels are reduced, but acidification will destroy corals in the longer term unless co2 levels reduce. Note that altering the quality of light reaching corals, through cloud cover changes may affect the corals

Yes, the contribution to arcus outlook deviates from the normally conservative MONTH approach. Perhaps it's just different researchers. Many organisations have a range of views within them and the Outlook is not very public. I have been told by government and ngos alike not to use info wich may

If some material could be added to the ice as it reforms in the winter, could a layer of ice-crete be formed in startegic places to them slow the melt and physical break-up of the ise the following summer, and use this to build multi-year ice again? Especially in the shallow coastal waters off

Hi all, I'd propose you put this hypothesis to Dan Laffolley (you can google him). There are so many responses to this I am overwhelmed and can't respond coherently. Apart from anything else, my understanding is that decay of ocean matter would release noxious gases. So while there may be O2,
