What is the impact of Arctic sea ice loss on global warming patterns?

Estimates suggest that the loss of Arctic sea ice, together with reductions in snow cover over the boreal land areas, will exacerbate global warming by 25-40% as the darker Arctic surfaces on water and land absorb more solar energy (Duan, Cao, and Caldeira, 2019; Pistone, Eisenman, and Ramanathan, 2014).
