montée des eaux : révision en cours

[Jean-Luc P]

Bonjour, commentaire d'un article de Science par news@nature :

La montée des eaux est estimés au mieux à 88 cm d'ici 2100 par l'IPCC, reprise par le GIEC (Groupe International d'étude du climat).

On parle de plus en plus d'un ordre de grandeur en mètres, de l'ordre de 5 mètres.

So, what can we expect?

In 2001, the Intergovernmental Panel on Climate Change (IPCC) predicted that sea levels would rise by a maximum of 88 centimetres by 2100. It added that further warming could trigger polar ice-cap melting, which might result in sea-level rises of more than 5 metres by the year 3000.

But Overpeck and colleagues' work, published in this week's Science1,2, indicates that metres of rise could happen much more quickly, potentially within the next 100 years.
