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. Ali in an article published on 24/11/2020 in "The conversation".
The researchers present the strong regional trends and more circumstantial factors that played a significant role in (…)

Brief published by CNRS-INSU - November 18, 2020

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.

IRD Press Release - November 18, 2020

Researchers from IRD, CNRS and UGA participated in a European study on sources of fine particles harmful to health, coordinated by the Paul Scherrer Institute (PSI, Switzerland). Their results, published in the journal Nature on November 18, 2020, reveal the harmful nature of fine particles in the atmosphere through their oxidizing potential. They suggest that this indicator should be taken into account in the future in air quality control measures for the health of people around the world. (…)

Like every fall since 2007, the French-Nepali joint expedition is about to depart for the Everest region to survey the mass balance of three glaciers. This field campaign is a joint project between French partners (Institut de Recherche pour le Développement/Institut des Géosciences de l’Environnement) and Nepali partners (Tribhuvan University/International Center for Integrated Mountain Development). Within four weeks, the team will trek to the glaciers and do the annual measurements of (…)

Over 99% of terrestrial ice is bound up in the ice sheets covering Antarctic and Greenland. Even partial melting of this ice due to climate change will significantly contribute to sea level rise. But how much exactly ? For the first time ever, glaciologists, oceanographers, and climatologists from 13 countries have teamed up to make new projections. Their modelling efforts, involving CNRS and CEA researchers, show that the Antarctic Ice Sheet may account for up to 30 cm of sea level rise (…)

Floods and river floods are among the most destructive natural disasters, resulting in many loss of life, infrastructure damage and economic hardship. Companies are now increasingly threatened by such floods, mainly because of the increasing exposure of goods and people in risk areas, but also because climate change is expected to change the magnitude, frequency and seasonality of floods. An accurate assessment of the flood hazard is therefore crucial for the sustainable development of (…)

An international team, involving French researchers from the Institute of Environmental Geosciences (IGE / OSUG, University Grenoble Alpes / IRD / CNRS / Grenoble INP), studied a particularly devastating flood event, caused by the sudden draining of a pro-glacial lake in the Bhotekoshi / Sunkoshi Valley, Nepal. Based on a particularly innovative observation technique based on the seismic analysis of soil vibrations, the authors bring unprecedented observational constraints on the physics of (…)
