ishitar comments on Iceberg 4 miles wide breaks off from Greenland glacier: "And so here we come to the coup de grace. At any time it seems the house of cards could come tumbling due to all these converging factors and modern society would collapse, perhaps resulting in the deaths of hundreds of millions to billions. Bad, but maybe survivable for the human race. However, in geologic time we have detected prior mass extinctions and the mechanisms for these extinctions is not well understood. Both AGW deniers and “believers” have been intimately focused on CO2: massive historical CO2 concentrations, sunspots, Maunder minimums, little ice ages. Few people focus on the methane - and we look above and see how many feedbacks with methane there are and the fact that methane is 86 times more potent a greenhouse gas in large burps as CO2 (25 times as bad accumulated over 100 year period) and we say ruh roh.
