Hi Brumar89; I sometimes fret about the next big downturn in temperature but we've got tools our ancestors didn't have. If I were a farmer in Canada and became convinced that there was a chance that my growing season was going to be cut short due to snow cover, I'd consider plowing it under. This sort of thing would vastly increase the albedo of the fields and help the sun melt the snow. With the onset of cold weather and problems in growing crops the high price you'd get from fields you'd saved would easily pay for the diesel needed to go through an extra round of plowing. And if the snow was too deep for plowing, I'd spread carbon black or powdered charcoal or powdered coal. The amount needed, in kg/ha, is roughly equal to what farmers spread in terms of fertilizer but it's probably cheaper. This increases the rate at which snow goes away around 4x. If all this didn't work, then you'd have to build stuff above the snow level. It would mean that we'd be paying a much higher percentage of our income on food but I think we'd live. A society in that situation couldn't afford nearly as many hangers-on as we've got now, of course. -- Carl
