New study suggests 2021 heat wave triggered shellfish die-off

LOS ANGELES, June 22 (Xinhua) -- The 2021 heat wave in the United States triggered the shellfish die-offs in Washington and British Columbia, according to a new study published earlier this week.

An excruciating heat wave blanketed the Pacific Northwest in late June 2021. Temperatures in Oregon, Washington and British Columbia soared to well above 100 degrees Fahrenheit (37.8 degrees Celsius), with Seattle setting an all-time heat record of 108 degrees Fahrenheit (42.2 degrees Celsius) on June 28, according to the research published in the journal Ecology.
