I have now removed links that I included here to the AMEG (Arctic Methane Emergency Group) website. I have taken this action, not because I disagree with their message on the acute situation regarding ice melt in the Arctic (on the contrary I couldn't agree with their findings more) but I cannot in any way condone or promote their plans for a geoengineering solution to the issue. These are very dangerous people whom I would now classify as the archetypical 'Mad Scientists'. I do not say that their crazy schemes would not work in some way but would ensure that we have a chance to continue to live, at least for a while longer, in a world just as fucked up as the one we have engineered for ourselves already. If we survive as a species at all then it would be better to not do anything more outrageous than we already have done to the planet.
All or most of us alive now, are going to die in one or more horrible ways, possibly not too far in the future. If I should be one of those who might survive, I do not want to have to live in a mad scientist's nightmare.
