A billion marine animals died off the Pacific coast of Canada due to the temperature

An estimated one billion marine animals, including mussels, oysters and sea stars, died after a record-breaking heat wave along Canada's Pacific coast in late June, highlighting its effects on an ecosystem unaccustomed to extreme weather events, according to the newspaper. New York Post".

A recent heat wave has turned some of Canada's Pacific waters into a marine cemetery. On Denman Island in the Pines Sound, mussels, oysters and sea stars are plucked fresh from the water, but they're dead from the heat.

Clam picker Dale Warren was shocked to see so many dead oysters unfit for consumption due to the normal temperature, saying: "We knew the heat might have been bad but we didn't expect to see what we saw."

This part of the Canadian coast is known for its refreshingly cool waters and ideal conditions for oysters to grow, he says, but now the changing weather can only mean disaster for many like him in the industry.

A team of researchers estimates that more than a billion marine animals along the coast were killed by extreme temperatures after a record heat wave in June that also killed hundreds of people in the Pacific Northwest.

According to one study, a heat wave would have been "virtually impossible" without climate change. Scientists say climate change has increased the likelihood of such a heatwave occurring in the region 150 times.

They also warned that the extreme event could start every five to 10 years by 2040 if current greenhouse gas emissions continue.
