The life of the microscopic algae that inhabit snow at high elevations is still relatively unknown. Researchers from the CNRS, CEA, Météo-France, INRAE and the l’Université Grenoble Alpes have therefore created the ALPALGA consortium to study this little-known world, threatened by global warming. Scientists will publish their initial results in Frontiers in Plant Science on 7 June 2021, describing for the first time the distribution of dozens of mountain microalgae species according to elevation.

Antarctica has experienced substantial temperature changes, particularly since the last ice age. An international collaboration involving CNRS scientists has just challenged previously accepted estimates of these variations with new measurements published June 4, 2021 in Science. Their study highlights the differences between the functioning of East and West Antarctica, linked in particular to different variations in their altitude.
Scientists have produced the most reliable estimates to (…)

Last month, a new project coordinated by the IGE has started. With 10 international partners from France, Norway, the United States, Italy, the United Kingdom and Germany, the SASIP project aims to develop a new model for sea ice - the large sheet of ice floating on the surface of the polar oceans - capable of resolving the complexity of its dynamics in order to improve its representation in the future generation of climate models. SASIP also aims to provide a new perspective on our understanding of the impact of global warming on the Arctic and Antarctic sea ice covers, and the numerous feedback loops involved in controlling the climate at larger scale.

The CRiceS project, or Climate relevant interactions and feedbacks : the key role of sea ice and snow in the polar and global climate system, will contribute to a more precise understanding of the ocean-ice-snow-atmosphere system to deliver improved models that describe polar and global climate.
This project is coordinated by Risto Makkonen (Finnish Meteorological Institute).
Jennie Thomas (IGE-CNRS) is the scientific coordinator of the project. (…)

We can halve the contribution of land ice to sea level rise this century, if we increase the ambition of our emissions commitments sufficiently to meet the goals of the Paris Agreement
The latest Special Report on Ocean and Cryosphere Change in a Changing Climate (SROCC) prepared by the Intergovernmental Panel on Climate Change (IPCC) in 2019 projects a global average surface atmospheric warming in 2100 of between 1°C and more than 4°C relative to the period 1986-2005 depending on the (…)

Sea level has been going up and down in the last millennia and while moving a camp wasn’t a big deal for our ancestors, moving today Venice or New-York is a different story. Sea level is currently rising at an accelerated rate due to the melt of land-based ice : glaciers, the Greenland and the Antarctic ice sheet. How high is the sea level going to be in 10 years, 50 years, 80 years, 500 years ? How do we calculate how much the seas are going to rise ?

The entire Sahelian region was affected by unusually high flooding, from the Atlantic coast to Ethiopia and Somalia. What happened this summer, particularly in the middle Niger River, has all the characteristics of an entry into a new hydroclimatic era," explains T. Lebel, G. Panthou, T. Vischel and A. Lebel.

The three Greenlandic glaciers Jakobshavn Isbræ, Kangerlussuaq and Helheim are the largest contributors to the loss of mass in Greenland. However, they alone contain enough ice to raise the global sea level by 1.3 m if they were to disappear completely.
