Countdown to an Ice-Free Arctic: New Research Warns of Accelerated ... gigatons of ice per year by 2100 in a scenario of high greenhouse gas emissions (SSP585), according to three ...
Using 300 computer simulations, scientists predicted that the Arctic's first ice-free day is guaranteed to occur within nine to 20 years regardless of how humans alter their greenhouse gas emissions.
This study highlights the role of deep Arctic lake sediments in greenhouse gas emissions, emphasizing their impact on permafrost carbon feedback mechanisms.
