Ist es ein Wunder, dass Entscheidungsträger immer weniger Vertrauen in die Verlautbarungen dieses politschen Vereins haben? The UN’s chief climate change negotiator has predicted that a Barack Obama victory next month would jump-start progress toward global limits on carbon emissions. Dr Rajendra Pachauri, head of the UN intergovernmental panel on climate change (IPCC), said yesterday that other nations would solidify their position on emissions caps after watching how the new American president approaches the issue. The IPCC’s mandate states that its reports on climate science should remain “policy neutral”, giving a ring of the unexpected to Pachauri’s remarks on the US political scene. He made no similar remarks about the climate-change policy of Republican nominee John McCain.
