2022-04 Unraveling the link between Indian Monsoons and Arabian sea upwelling
Anta-Clarisse Sarr from CEREGE finally discovers that missing link: It is the East African uplift and Arabian emergence that increased the deflection of the Somali Jet responsible for upwelling and monsoons. This result from numerical simulations of upwelling and climate works perfectly with the timing of proxies.

2021-10-22. Climate variability and biome distribution
Delphine Tardif used climate models to explore the greenhouse to icehouse transition when the world turned cold 50 to 34 million years ago. She finds that short astronomical (“Milankovitch”) cycles, although usually not considered, have had a strong effect. They have radically changed the geographic distributions of climates and biomes. This can explain major changes such as the famous “Grande Coupure” that completely redefined Europe and Asian fauna and flora.
Tardif, D., Toumoulin, A., Fluteau, F., Donnadieu, Y., Le Hir, G., Barbolini, N., Licht, A., Ladant, J.B., Sepulchre, P., Viovy, N., Hoorn, C., and Dupont-Nivet, G. (2021).
