Bjørn Lomborg  Ne niant ni la réalité du changement climatique, ni le fait qu'il résulte de l'activité humaine, l'auteur estime toutefois trop élevé le coût des politiques préconisées dans le cadre du protocole de Kyoto pour des résultats sans doute très modestes. Rappelant que l'on meurt globalement plus de froid que de chaud sur Terre, il suggère notamment que le réchauffement climatique est susceptible de sauver davantage de vies que d'en détruire.

Art arda düzenlenen iklim konferanslarının aslında pek de bir yararı olmadığını savunanlar da var. Bunlardan biri de Danimarkalı entelektüel Björn Lomborg. 

CLIMATE | 22.09.2009 Cutting carbon emissions won't stop climate change, expert says  As world leaders meet at the UN to discuss climate change, Bjorn Lomborg tells DW he expects little to come from the talks.

09-21-2009: Climate Change: A Perilous Path

Our costly ''solutions'' could be more harmful than global warming itself. Evidence is growing that relatively cheap policies like climate engineering and non-carbon energy research could effectively prevent suffering from global warming, both in the short and long term. Unfortunately, political leaders gathering at a special meeting of the United Nations in New York this week will focus on a very different response. (...) 

When world leaders meet for the climate-change summit in Copenhagen this December, they will make decisions that will affect the world for many generations. Three months before that meeting, there is an alarming absence of serious discussion about what these decisions should be. What passes for debate is usually a shouting match between those who believe that climate change is not real and those who believe that it will end life on Earth. We are all, it seems, either "deniers" or "believers." (...) 

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. (...)    

Cutting future emissions is much cheaper than slashing present ones, argues Bjorn Lomborg
