Worse than Worst Case

Worse than IPCC Worst Case Scenario


Excerpts from: http://mwcnews.net/content/view/20133&Itemid=1


"Thus data from 2 independent sources (see: "Recent CO2 rises exceed worst case scenarios", New Scientist, 2007) reveal that actual rates of carbon dioxide (CO2) emission are the same or worse than in the worst case IPCC scenario A1F1 that, according to the 2007 IPCC Summary, will lead to catastrophic, long-term stabilization at (upper estimates) 790 ppm CO2, and a 6 degree centigrade higher temperature and 3.7 meter sea level rise relative to pre-industrial levels; i.e., CO2 catastrophically at twice today's level of 385 ppm , temperatures 4-5 degrees Centigrade above today's and sea level 0.8-3.5 metres above today's.


The latest scientific findings are that the IPCC 2007 Report has greatly under-estimated the rate of melting of Arctic Ice, including that of Greenland - water from melted ice is lubricating and speeding up the movement of glaciers to the sea; the so-called "albedo flip" involving converting light-reflecting, white ice to light-absorbing, dark sea is dramatically speeding up loss of Arctic sea ice; and the consequent increase in temperature in the Arctic provides a positive feedback to increase sea ice and Greenland ice sheet melting (for analysis and dramatic images of Arctic ice melting."


" The essence of "Climate Code Red" ( http://www.climatecodered.net/) is that the World is facing a Climate Emergency and a Sustainability Emergency because we have passed crucial atmospheric CO2 "tipping points", "Climate Code red" further declares that, as demanded by Dr James Hansen, we need not "CO2 emissions reduction targets" or "zero CO2 emissions" but NEGATIVE CO2 EMISSIONS to return the Planet to a safe, sustainable 300-350 ppm CO2.


"At this Melbourne Climate Convergence meeting various activist groups decided to form a Climate Emergency Coalition to urgently spread the message and to lobby for a Declaration of a State of Emergency in Australia and the World to meet the Sustainability Emergency. As Dr Hansen has said (see above), we urgently need a lowering of atmospheric CO2 to about 300-350 ppm and a major step now must be an immediate moratorium on coal power - we must keep fossil fuels in the ground to save Humanity and the Biosphere."
