Zoology professor Christopher Harley estimates that a billion oysters and other sea creatures may have died in a heat wave in Vancouver last week.
The West Coast of North America has been observed maximum temperature حرارة It will end in June.
Now it Extreme heat has reached Death Valley in the United States, but until then it was set Temperature records in both the United States and Canada for several consecutive days. Temperatures peaked at 47.8 degrees in Hermston, Oregon, and 49.5 degrees in Lytton, British Columbia.
he drives harley lab It looks at the effects of climate change along the coast. On Sunday, June 27, he noticed dead mussels lying and rotting on Kitsalano Beach in Vancouver.
– It was a disaster
– I could smell the beach before I got there, because there had already been many dead animals since the day before, which were the warmest. I just started checking out my local beach and thought “this can’t be good.”
Heat wave: here it measures 54.4 degrees
The next day, he and a student took a trip to Lighthouse Park in West Vancoucer, a place he’s visited regularly for the past twelve years or so.
– It was a disaster there. He told CNN it was a very extensive oyster bank that covered the coast and most of the animals died there.
Too hot for missiles
According to the professor, the shells stick to rocks and other surfaces that are usually exposed to air and sun at low tide. But they cannot withstand temperatures above 38 degrees for a very long time.
In downtown Vancouver, temperatures hovered between 37 and 39 degrees this weekend. It should be warmer on the beaches.
Using a heat-seeking camera, Harley and the student observed surface temperatures of about 52 degrees.
When the low tide coincides with the hottest time of the day, the animals cannot survive until the water rises again, according to Harley.
It is estimated that up to a billion shells and other marine animals died in the oceans and straits around Vancouver Island.
danger warning تحذير
Marine biologist Brian Hellmuth of Northwestern University also told CNN that when mussel banks die like corals, this is a marine health warning that can have significant ripple effects.
When we see mussel banks dying, they are like trees in a forest that provide a home for other species. So it’s very clear that the oyster shell is dying, he says.

Correction: An earlier version of this case stated that there were extreme temperatures on the west coast of North America in late July. We’re not quite there yet, so the right thing to do is the end of June. The bug was fixed on 11.07.21 at 11.58.
