A 308 year record of climate variability in West Antarctica
Geophysical Research Letters

We present a new stable isotope record from Ellsworth Land which provides a valuable 308 year record (1702–2009) of climate variability from coastal West Antarctica. Climate variability at this site is strongly forced by sea surface temperatures and atmospheric pressure in the tropical Pacific and related to local sea ice conditions. The record shows that this region has warmed since the late 1950s, at a similar magnitude to that observed in the Antarctic Peninsula and central West Antarctica; however, this warming trend is not unique. More dramatic isotopic warming (and cooling) trends occurred in the mid-nineteenth and eighteenth centuries, suggesting that at present, the effect of anthropogenic climate drivers at this location has not exceeded the natural range of climate variability in the context of the past ~300 years.

Je résume: le réchauffement que l’on voit dans l’Antarctique en ce moment n’est pas différent de celui qui a été observé depuis 300 ans. Il y a 300 ans on se déplaçait à dos de cheval, pas en VUS…

Il va de soi que cet article, publié dans un journal scientifique renommé, sera ignoré par nos médias. Parler de cet article équivaudrait à dire qu’il n’existe pas de consensus scientifique sur le réchauffement climatique…
