Marine cloud whitening, and other ideas. We have precious little to show for nearly 20 years of efforts to prevent global warming. Promises in Rio de Janeiro in 1992 to cut carbon emissions went unfulfilled. Stronger pledges in Kyoto five years later failed to keep emissions in check. The only possible lesson is that agreements to reduce carbon emissions are costly, politically arduous and ultimately ineffective. But this is a lesson many are hell-bent on ignoring, as politicians plan to gather again—this time in Copenhagen, Denmark, in December—to negotiate a new carbon-emissions treaty.

Striking the right balance between preventing global warming and adapting to its effects is one of the most important – and most vexing – policy questions of our age. It is also often ignored. (...)

Rhetorical excess undercuts the case against global warming. By John Vinocur. 

The Reuters article about Poznan quotes Lomborg's article that was published one day before in Forbes: (...) Meanwhile, Bjorn Lomborg, author of the "Sceptical Environmentalist" writes in the business magazine, Forbes, that rather than wasting money on meetings to decide global agreements which will inevitably be ignored, the world's poorest would be better served by improvements to their living conditions now. "Interventions like improving malnutrition and child health in the Third World deserve a much higher priority than carbon cuts to battle climate change," he says.

Český prezident Václav Klaus se na něj při boji proti zastáncům rychlé akce, která by zabránila globálnímu oteplování, už nejspíše nebude odvolávat. Celebrita v debatě o klimatické změně, dánský akademik Lomborg, změnil dres. Globální oteplování nyní považuje za akutní problém, který však může jako kapitán flotily plachetnic hravě vyřešit.
