The heatwave in the Pacific Northwest, Canada, killed more than 1 billion sea creatures: researchers

As extreme weather events intensify in intensity and frequency around the world, wild animals are often the first to be affected.

An estimated 3 billion animals have been killed in Australian bushfires from 2019 to early 2020.

In California, officials have warned that protected salmon populations may not survive the sweltering summer season. Millions of salmon were transported from the California Department of Fish and Wildlife using special trucks.

In Florida, hundreds of fish have spilled onto the beaches of Tampa Bay and St. Petersburg, and the Florida Fish and Wildlife Conservation said the fish killings should be linked to the red tide.

Red tides caused by algal blooms have been lethal in the area in the past. Other animals, including dolphins, sea turtles, and manatees, died during a similar outbreak in 2018.

Although the reason for the fish’s death is a matter of debate and polluted sewage could be the culprit, NPR reported that blooms are rarely seen in the summer and in the Tampa Bay area.

According to the Environmental Protection Agency, warmer waters, a change in salinity, more carbon dioxide, changes in rainfall, and rising sea levels all combine to provide a hospitable environment for blooms.

Yet when University of British Columbia professor Christopher Harley announced that more than 1 billion sea creatures were killed off the coast as a heat dome discovered over the Pacific Northwest and Canada earlier this month, it was still a shock.

“So far, my students and I have recorded dead animals on beaches that stretch over hundreds of kilometers of coastline,” the marine biologist told E&E News Thursday. “Eventually, parts of the British Columbia coast may become more like Hong Kong and other warm parts of the world, where many of the intertidal species die every single summer.”

Harley’s team estimated that 1 million mussels had died in a space the size of a tennis court and 100 million barnacles had died in an area of ​​1 kilometer.

According to Live Science, the latest heat-induced mass killing of shellfish occurred in California’s Bodega Bay in 2019.

Northeast of Vancouver, temperatures hit three digits during the heatwave, with Lytton, British Columbia recording a high of more than 121 degrees Fahrenheit, according to Environment Canada British Columbia’s Twitter account.

Later, that village’s nearly 1,000 residents fled for their lives as a fire tore apart their community, destroying most of their homes.

One man said he saw his parents die when a power line fell on them as they tried to escape the flames.

Hundreds in the United States were killed by excessive heat, and the National Oceanic and Atmospheric Administration (NOAA) later reported that June was the hottest month on record in North America.

According to a US Drought Monitor update on July 8, nearly 78 million people were in a drought area in the contiguous United States, with 57.52 percent of the region marked “Abnormally Dry” to “Exceptional Drought”.

That number is up from nearly 44 percent of the American continent in drought in early June.

Harley warned that the loss of intertidal animals such as mussels could have a negative effect on the region’s biodiversity, noting that many have reported observations of deaths up and down the mainland coast.

“For most of the weird and wonderful creatures that call the mussel bed home, we don’t even know enough about them to know how many have been lost and if and when they will recover,” he lamented.

Fox News reached out to Harley for further comment, but did not immediately receive a response.

In its National Climate Assessment, NOAA wrote that the fact that the Earth’s climate is changing is “apparent in the United States in a wide range of observations.”

“Global warming over the past 50 years is mainly due to human activities, mainly the burning of fossil fuels,” the agency said, noting that “stronger evidence confirms” that an increase in extreme weather and climate events such as waves of heat is related to human activity. activities.

“Human-induced climate change is expected to continue and accelerate significantly if global emissions of heat-trapping gases continue to rise,” NOAA warned.
