Researchers from a Quebec university suggested Wednesday that global warming has caused changes in Canada's most northerly lake. Aquatic life in Ward Hunt Lake — located on a small island north of Ellesmere Island in Canada's High Arctic — has gone through substantial changes in the past two centuries. "The speed and range of these transformations — UNPRECEDENTED in the lake’s last 8,000 years — suggest that climate change related to human activity could be at the source of this phenomenon." The research suggests the lake was permanently frozen in the past, but changes in the aquatic life "indicate that current conditions make the lake a more favourable location for algae growth than it was in the past.
Adapting to the damaging effects of climate change, plants are gradually moving to where temperatures are cooler, rainfall is greater, f...
