Dr. Leonard Barrie reflects on the observable impacts of climate change both at home and in the Arctic. He notes significant changes in the timing of the sugaring season in southern Quebec, with maple tapping starting earlier due to warmer temperatures. Barrie also highlights the drastic reduction in multi-year ice fraction in the Arctic Ocean, leading to the projection that the Arctic Ocean will become a seasonal lake by the middle of this century, with implications for atmospheric chemistry and ocean dynamics. He discusses the turbulence over open water, sea salt deposition into the snowpack, and the profound effects of diminishing sea ice on Arctic communities and subsistence hunting practices.
