Press release, Bonn 14 December 2015

peter droege klein neuLast Saturday the 'climate negotiating parties’ in Paris achieved consensus on a binding set of agreements aiming at a maximum of 1.5 to 2 degrees temperature increase as target range. This was stated with such confidence that one could forget for a moment that the Earth's atmosphere has no thermostat: No one can control or assure an outcome, certainly not with resolutions alone, nor when there is already a greenhouse gas concentration far too high for the kind of relative climatic stability that has made human evolution possible. Methane venting from melting permafrost and destroyed rain forests and moorlands adds to the still rising greenhouse-gas stream from the combustion of coal, oil and gas. A 1.5-2 degrees Celsius target without a firm limit on emissions and an unwavering and bold commitment to 100% renewables is impossible to achieve. The Paris pledges are likely to put us above 2, if not 4 or 5 degrees.
