Global warming causes permafrost - the planet’s permanently frozen ground - to melt, and it also causes carbon to be released. This mechanism could release up to twice the amount of CO2 as the atmosphere currently contains. The French and Canadian team at the Takuvik laboratory, created by the French centre for scientific research (CNRS) and Laval University in Quebec, have launched the APT (see asterisk)

(asterisk) APT: Acceleration of Permafrost Thaw by Snow-Vegetation Interactions.
project to better understand this process by involving the Inuit community in its work: it will be informed and its schools will be directly involved in taking ground-temperature readings.

Around 20,000 to 10,000 years ago, the planet was emerging from the last ice age. This natural rise in temperatures, associated with an increased atmospheric concentration of greenhouse gases plus a rise in sea levels, affects the environment in a number of ways. The FATES (see asterisk)

(asterisk) FAst Climate Changes, New Tools To Understand And Simulate The Evolution of The Earth System.
project aimsto study, date and precisely log these changes by analysing natural climate archives (polar ice, marine and continental sediments, etc.). These data will be used to test the reliability of digital models currently used to predict the future of our climate. Coordinated by the French climate and environmental science laboratory (CNRS/CEA/UVSQ), this project will bring together multidisciplinary research teams from the Université Paris-Saclay over a three-year period.

By studying past climate evolutions, some of which have been abrupt, we can learn about current climate change and the relationship between natural variation and human disturbance. The aim of the CPATEMP (see asterisk)

(asterisk) Continental PAst TEMPeratures since the last glacial cycle and recently developed organic biomarkers.
project, of the European Centre for Environmental Geoscience Research and Education (CEREGE, CNRS/Aix-Marseille Université/IRD/Collège de France), in partnership with research teams in Europe and Africa, is to help improve knowledge about our climatic past by studying recently discovered bio-markers: glycerol dialkyl glycerol tetraethers (GDGTs). Found in the sediments of some lakes, they can be used to recreate the climatic conditions at the time the sediments were deposited.
