A study of feedbacks and the formation of climate trends in the Arctic climate system
Abstract The role of the ocean in the response of the climate system to an increase in the atmospheric CO 2 concentration is investigated by using a system of numerical models, ICMMG-PlaSim. The results of this study are summarized as follows: a) the ocean, to some extent (up to 20%), contributes to...
