A new European network of young researchers to unveil past climate changes in Antarctica

Published on October 15, 2021

A network of international researchers launches a European collaboration on October 14th 2021. This collaboration will train a new generation of scientists to understand how past climate changes impacted Antarctica

Emilie Capron, paleoclimatologist at the IGE receives the AXA Prize for Climate Science

Published on August 10, 2021

Emilie Capron, researcher at IGE received the AXA Climate Science Award for her contribution to the understanding of future abrupt climate change.
Her work focuses on the study of polar ice cores to reconstruct past climate variations over the last 150,000 years, in order to improve our understanding of their causes and global impacts on the Earth system. Emilie Capron has been selected as one of the four winners of the AXA Climate Science Awards.

Release of the first volume of the IPCC Sixth Assessment Report, 2021 : The Physical Science Basis

Published on August 09, 2021

The IPCC (Intergovernmental Panel on Climate Change) is releasing today, August 9, 2021, the first volume of its sixth report, which summarizes the latest physical understanding of the climate system and climate change, bringing together the latest advances in climate science and combining multiple climate indicators.

Observing how water flows below glacier using using seismic observations

Published on July 09, 2021

Article published originally here
Author : Ugo Nanni - 09/07/2021
What is it about ?
We deployed a dense array of 98 seismic sensors on the surface of the d’Argentière glacier in the French Alps and recorded one month of seismic noise generated by subglacial water flow during the onset of the 2018 melt season. With and innovative approach we produce a two dimensional map of the subglacial drainage system and observe the evolution of water flows over time. Early in the observation (…)

When PhD students from IGE learn about scientific communication and take control of a Twitter account

Published on June 25, 2021

On Monday 14 June 2021, 9 PhD students were given the green light to post in turn on the @EnDirectDuLabo Twitter account.
@EnDirectDuLabo, what is it ?
This Twitter account invites researchers to share their daily lives and research. Each week, subscribers discover what is hidden in the labs and what "doing science" means. The public can discover the work of PhD students, engineers, university lecturer,researchers and technicians. Discovering the many facets of research in France is the (…)

ALPALGA : the search for mountain snow microalgae

Published on June 09, 2021
Press release CNRS / UGA / Météo-France / INRAE / CEA

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 : what temperature variations since the last ice age ?

Published on June 04, 2021
CNRS press release

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 (…)

A new project started at IGE : The Scale-Aware Sea Ice Project (SASIP)

Published on May 27, 2021

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.

New Horizon 2020 project advances our understanding of polar processes in the global climate system

Published on May 21, 2021

https://ige-intranet.osug.fr/spip.p...
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 (…)

Limit global warming to 1.5°C and halve the land ice contribution to sea level this century

Published on May 06, 2021

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 (…)
