The warming effect of BC is in the Arctic of the same magnitude as CO2. <br />Once the arctic is sea-ice free in summer there will be a lot of feedbacks coming into play. There is the decrease of albedo of course. There will be a gigantic rise in three of the strongest greenhouse gases: water vapor, CO2 and methane. <br />The heat from the tropics, brought up North by the Ocean Conveyor Belt, will be able to help melting Greenland in stead of being released into space.Leonhttps://www.blogger.com/profile/10683125984623063867noreply@blogger.com
