Copenhagen, 9 December 2009 Independent analyses of current mitigation proposals on the table in Copenhagen by Nicholas Stern, the United Nations Environment Programme (UNEP), the Potsdam Institute for Climate Impact Research (PIK), Ecofys, Climate Analytics, the Sustainability Institute (C-ROADS), the European Climate Foundation and ClimateWorks (Project Catalyst) all point to the same conclusion: the negotiations must deliver the high-end of current proposals, and stretch beyond them, if the world is to have a reasonable chance of containing warming to below 2°C above pre-industrial levels, or the 1.5°C goal of many developing nations.
There is a narrow window of opportunity to have the possibility of achieving the global political and scientific consensus of avoiding a global warming of more than 2°C above pre-industrial levels or the 1.5°C goal of 100 developing nations. The concentrations of greenhouse gases in the atmosphere is increasing everyday and, without significant reductions in emissions, will soon reach levels at which the consequent changes in the Earth’s climate will have very serious, and potentially disastrous and irreversible, impacts.
