[QUOTE="Channel Hopper, post: 1063331, member: 175144"] Ice ages occur once every few hundred million years and absolutely no lifeforms survive intact when one comes. A glacial period, even a 'mini' one is going to be decades long, the chance of modern design tins surviving more than ten years intact is virtually zero. The management of animals and plants for consumption is certainly not a skill humans can do better than nature so in a time of austerity the only solution is going to be a dramatic thinning of the herd, potentially back to the numbers of previous cold snaps. Natural selection will actually be assisted initially by migration to the predicted sunny spots, then by the panic caused by man made conflicts once news gets out of the small numbers that could be sustained when the planet in the main freezes over. I don't think there are accurate accounts -yet - of the true frost lines accompanying each previous ice age, nor how to predict the region of the next one so there is cartainly not going to be management and orderly control. One technology that might allow pockets of humans a reprieve would be geothermal, for the artificial lighting for crops underground. Disused mines carefully modified after making safe could be converted for cultivation, though most of the energy would need to be used for scrubbing the atmosphere of contaminants including the water and waste generated by the eco farming community. There would be no chance of doing similar for livestock however, any meat would be sourced from the oceans and be in very limited supply owing to the smallest blocks in the natural food chain being squeezed to a region around the equator. Sea levels everywhere will change dramatically once the ice starts spreading from the higher latitudes, there is no accurate prediction by how much or even if it is to be a global drop or rise this time round. Thoughts of escaping to islands that already has the infrascructures predicted for surviving is a non starter since the ice will lock most of the regions together. [/QUOTE]
