A recent post say the decrease of the Arctic ice will increase global warming due the lack of reflection of light back into space. So my question is: How much is man contributing to global warming by the removal of snow?
I look over my yard and I see the driveway and street may take up 20% of the surface area of our plot. If you include the roof of the house (which accelerates the melting snow) and the planting of trees were once was grass (and thus preventing the light from returning to space), how much more light is absorbed versus return to space? Add in all the extra cities, roads, highways and malls, etc that have been built in the last 200 years, how much has global warming been increased by the removal of snow?
