Then he delivers a lecture on why the scientific community is so sure that climate change even exists. He speaks of a "purely physical" effect caused by concentrations of greenhouse gases in the earth's atmosphere that heat up the planet by a single degree Celsius. "What's more," says Jochem Marotzke, the head of the German Climate Consortium, "there is the affect of water vapor, which accounts for at least another degree."
Next Friday, Marotzke will travel to Berlin once again for a preparatory meeting at the Environment Ministry ahead of the next World Climate Conference in Durban, South Africa, at the end of November. He almost sounds as if his audience of politicians and ministers had never heard of climate change, as though thousands of them hadn't thronged together at more than a dozen World Climate Conferences over the last two decades.
Marotzke, also the director of the Hamburg-based Max Planck Institute for Meteorology, has no illusions about the current importance of climate policy. "The interest in Berlin and elsewhere has cooled off palpably," he says. The topic counts as one that doesn't necessarily need to be addressed, he adds, "because citizens are also turning away (and) no great pressure to act is placed on the politicians."
Still, the widespread indifference stands in disturbing contrast to the grim facts. According to the latest calculations of the US Department of Energy, CO2 emissions are rising sharply. Some 512 million more tons of greenhouse gases were emitted from smoke stacks, exhaust pipes and agricultural land.
