Dans le quatrième rapport du GIEC, publié en 2007, on peut lire que le réchauffement climatique pourrait provoquer la disparition de nombreuses espèces:

Global Warming

There is medium confidence that approximately 20-30% of species assessed so far are likely to be at increased risk of extinction if increases in global average warming exceed 1.5-2.5 °C (relative to 1980-1999). As global average temperature increase exceeds about 3.5 °C, model projections suggest significant extinctions (40-70% of species assessed) around the globe.

En 2013, le Dr. Chris D. Thomas affirme dans la revue Nature que le réchauffement climatique pourrait augmenter la biodiversité:

Human activity changes the environment, as last week’s release of a report by the Intergovernmental Panel on Climate Change reminds us. But not all change is bad. […] Climate change tends to boost regional diversity, because diversity increases with temperature and precipitation, both of which are rising (on average, but not everywhere).

Malgré ces contradiction n’oubliez pas que la science est définitive, que le débat est clos et qu’il y a consensus…
