Here in Edmonton we just had a reasonable but not excessive dump of snow - two to three inches, bringing the total depth on uncleared surfaces to about five inches. In Britain, an inch of snow can bring transport to halt. I remember that when I worked in Inverness that a rumour that the Drummochter Pass might be closed by snow led to the shelves of the local supermarkets being cleared of bread and toilet paper. In Britain the cost of having fleets of heavy-duty snow clearing equipment on hand for the two or three days when there is a heavy snow fall just does not make economic sense. Several years ago, one Saturday, here in Edmonton we spotted way more than usual more people out walking on the streets after a heavy-ish snow fall. It took a while for the reason for this to dawn on yours truly. It was going to take 15 minutes to dig cars out of the snow. People who hop in their cars to make a journey which on foot would take 10 minutes decided it was quicker to walk than dig out their vehicle. There were a depressing number of people here who leap into their pollution spewing cars to drive two or three streets. The cars would have to be dug out to go to work on Monday but a Saturday car journey to buy a carton of milk just wasn't worth all that digging. I wonder if it snowed every Saturday of the year how much that would cut global warming.
