A massive landslide on the west coast of Canada has had unprecedented impacts on one of the country’s giant fjords. The slide has wiped out salmon habitat in Bute Inlet, British Columbia, but also cooled the inlet’s waters, reversing the recent and worrying warming caused by a potent marine heatwave.
The landslide is a lesson in the sometimes-surprising nature of climate change’s effects across various ecosystems, says oceanographer Jennifer Jackson of the Hakai Institute.* “There could be interesting feedbacks that we haven’t considered,” says Jackson, who has been monitoring Bute Inlet’s conditions in monthly expeditions. In this case, climate change melted a glacier, which encouraged a landslide, which pushed glacial lake water into an otherwise-warming fjord. In other words, climate change first caused the inlet to warm—and then cooled it.
