Researchers discover what triggered Earth's last ice age — source — 30 April 2023 (LINK)
— The ocean gateways in the Canadian Arctic Archipelago served as a vital linchpin, determining whether ice sheets could form or not. The simulations indicated that as long as the ocean gateways in the Canadian Arctic Archipelago were open, the Northern Hemisphere's cooling due to Earth's orbital configuration allowed ice sheets to develop in Northern Canada and Siberia, but not in Scandinavia. The scientists conducted a second study where they created a simulation to investigate the impact of marine ice sheets blocking the waterways in the Canadian Arctic Archipelago. The diversion caused the North Atlantic deep circulation to weaken and freshen, leading to the expansion of sea ice and cooler conditions in Scandinavia. The simulation results indicated that this scenario was adequate to initiate the growth of ice in Scandinavia. Sediment records also demonstrated strong indications of a weakened deep ocean circulation before the formation of glaciers in Scandinavia, which closely mirrored the results obtained from the simulation.
The study proposes that even minor disturbances in the Earth's climate system could result in substantial and abrupt changes in ice sheet size and distribution, with far-reaching effects on sea level increase, ocean currents, and global climate patterns.
