Bhowmick, Mansi; Mishra, Saroj Kanta; Kravitz, Ben; Sahany, Sandeep; Salunke, Popat (2021): Response of the Indian summer monsoon to global warming, solar geoengineering and its termination. In Sci Rep 11 (1), p. 9791. DOI: 10.1038/s41598-021-89249-6. The response of the Indian Summer Monsoon (ISM) to global warming, solar geoengineering and its termination is examined using the multi-model mean of seven global climate model simulations from G2 experiment of the Geoengineering Model Intercomparison Project.

Bach, Lennart T.; Tamsitt, Veronica; Gower, Jim; Hurd, Catriona L.; Raven, John A.; Boyd, Philip W. (2021): Testing the climate intervention potential of ocean afforestation using the Great Atlantic Sargassum Belt. In Nat Comms 12 (1), p. 2556. DOI: 10.1038/s41467-021-22837-2. "Here, we analyse the CDR potential of recent re-occurring trans-basin belts of the floating seaweed Sargassum in the (sub)tropical North Atlantic as a natural analogue for ocean afforestation. We show that two biogeochemical feedbacks, nutrient reallocation and calcification by encrusting marine life, reduce the CDR efficacy of Sargassum by 20–100%." LINK
