... et PLEIN d'autres sujets dans Cryosphère : permafrost, impact sur les glaciers, mesures, modèles, balance d'énergie et de masse...

Une autre ligne de conférences traite du Climat passé, actuel, futur. Il y a juste trop de sujets pour que je les reprenne ici... j'ai juste aperçu un abstract sur des relevés sous-marins de Waddhams en Arctique en 2007...

Bref, il y a des dizaines de papiers récents sur le climat et l'arctique.

(et si un autre post en parle dans les topics Climat j'ai juste l'air d'un c... default_wink.png/emoticons/wink@2x.png 2x" width="20" height="20"> )

Bref, comme j'aime à dire : enjoy, servez-vous !

Résumé intéressant dans la rubrique "ocean sciences" :

The role of anthropogenic forcing on the recent increase in Antarctic sea ice extent

J. Turner

British Antarctic Survey, Cambridge, UK (J.Turner@bas.ac.uk / Fax: +44 1223 221279)

The time series of Antarctic sea ice extent computed with an improved Bootstrap

algorithm indicates that the increasing annual trend is significant at less than the

5% level. The trend is dominated by the changes in the autumn and in the Ross

Sea sector. There has been a trend towards enhanced cyclonic atmospheric circulation

over the Amundsen-Bellingshausen Sea resulting in greater northerly flow

down the Antarctic Peninsula and stronger southerly flow off the Ross Ice Shelf.

These changes are apparent in the ECMWF reanalysis fields and in the ensemble

mean of the IPCC Assessment Report 4 climate models, when integrated through

the late Twentieth Century with increasing greenhouse gases and depletion of

stratospheric ozone. These changes are statistically significant when compared

to pre-industrial control runs, demonstrating that the sea ice has increased as a

result of anthropogenic activity. Experiments with an atmosphere-only climate

model indicate that depletion of stratospheric ozone has contributed most to the

circulation changes.
