Image from our coring and modern sample campaign of the largest freshwater lake in the Caucasus, Lake Sevan. I will run GDGTs, pollen, and XRF analyses to reconstruct Sevan's Holocene climate and lake-level history and the impact of these changes on humans living here. #CEPAM #ISEM #LGLTPE

In 2020, only 3.6% of the world’s population lived outside their country of birth. Imagine when 33% of humanity have to migrate.

Rather crazy situation unfolding in northern #Quebec. Thunderstorms, some potentially severe, having the potential to ignite new #wildfires. Conditions pretty dry already. Maximum temperature forecasted on wednesday: 29°C (Check the date...October 2nd...)
