Voici ce qu’on disait en 2009 à propos du réchauffement dans l’Arctique:

A new report says Arctic climate change is happening faster than anyone anticipated and may soon be forcing more rapid warming on the rest of the planet. “It is a tipping point,” said Craig Stewart of the World Wildlife Fund, which was to release the report Wednesday in London. The report is an attempt to update the work of scientists involved in the 2007 Intergovernmental Panel on Climate Change.

Voici ce qu’on dit en 2011 à propos du réchauffement dans l’Arctique:

Danish researchers analysed ancient pieces of driftwood in north Greenland which they say is an accurate way to measure the extent of ancient ice loss. Writing in the journal Science, the team found evidence that ice levels were about 50% lower 5,000 years ago. They say changes to wind systems can slow down the rate of melting. They argue, therefore, that a tipping point under current scenarios is unlikely.

Et on voudrait nous faire croire que le débat scientifique sur le réchauffement climatique est terminé parce que nous avons un consensus fort…
