Global ice-sheets are melting at an increased rate; Arctic sea-ice is disappearing much faster than recently projected, and future sea-level rise is now expected to be much higher than previously forecast, according to a new global scientific synthesis prepared by some of the world’s top climate scientists.

A monitoring campaign to better understand pollution produced by large conurbations will be carried out in the Paris area during the whole month of July.

Does ozone have an impact on the ocean’s role as a “carbon sink”? Yes, according to researchers from three IPSL laboratories. Using original simulations, they have demonstrated that the hole in the ozone layer reduces atmospheric carbon uptake in the Southern Ocean and contributes to the increase in ocean acidity.

New very high resolution ice cores analyses from Greenland reveal that the climate has changed very suddenly, within a few years, at the end of the last ice age, about 10 000 years ago.

Epoca aims to better understand ocean acidification, to study its effects on marine biology and to predict them for the next century, and especially to make recommendations to policymakers.

To predict the future evolution of greenhouse gases, to trace their evolutionary past, further and further over the time, is a major issue. In analyzing the Antarctic ice extracted during the EPICA ice drilling project, the French LGGE and IPSL scientists, together with several international partners, managed to push the existing limits.
