Sea surface temperatures and deeper water temperatures reached a new record high in 2024

A new study published in Advances in Atmospheric Sciences has found that ocean warming in 2024 has led to new record high temperatures. The ocean is the hottest it has ever been recorded by humans, not only at the surface temperature but also for the upper 2000 meters.

Hot river water curbs output at French #NuclearPlant

August 2, 2024

PARIS, Aug 2 (Reuters) - "Electricity production at the #Golfech nuclear plant in southern #France was reduced by 1 gigawatt (GW) on Friday, EDF data showed, after the utility said high #WaterTemperatures on the #GaronneRiver could mean reduced output until Aug. 10.

"The restrictions are the first this year linked to high temperatures, which typically represent less than one percent of annual production.

"Nuclear output in France has been relatively consistent this year, following years of disruption caused by extended maintenance.

"EDF sometimes limits production when temperatures are near a threshold that varies depending on the nuclear plant.
On Thursday it extended a warning of possible reduced output that had been expected to end on Saturday.
EDF was not immediately available for comment.
LSEG data showed that the 28°C (82.4 Fahrenheit) temperature limit for the River Garonne that cools Golfech was breached once on July 31.

"Only one of several forecasts showed temperatures surpassing that level over the next week."

"'Dropping temperatures in France should ease the pressure and allow the plant to return to normal generation levels sooner. However, the beginning of next week has temperatures rising once again and problems could start once again,' LSEG analyst Ulrich Weber said."

#ClimateChange Contributes to Shift in #LakeErie’s Harmful #AlgalBlooms

Blooms over the past decade have started earlier in July and had longer peaks, according to #NOAA researchers.

"Lake Erie’s harmful algal blooms have started sooner and had longer peak periods over the past decade compared to earlier years, newly released data shows. Warming temperatures linked to climate change are a cause, according to researchers for NOAA’s National Centers for Coastal Ocean Science, with interactions among species likely playing a role as well.

"The NOAA scientists discussed the shift and forecast a moderate to above-moderate algal bloom for the lake’s western basin this summer during a briefing last month at Ohio State University and Ohio Sea Grant’s Stone Laboratory, off the coast of Put-in-Bay on Lake Erie.

"Algal blooms occur when #cyanobacteria, or blue-green algae, grow out of control due to a combination of excess #nutrients, #weather patterns and other #ecological factors. The blooms can be a serious public health problem because some types of cyanobacteria produce toxins. #Microcystin, for example, can lead to skin rashes, gut problems and liver and kidney issues. Relatively high levels of it in August 2014 prompted a two-day shutdown of #Toledo’s public #WaterSupply, which comes from Lake Erie."

"What is causing this?
Things to know about FDA warning on paralytic shellfish poisoning in Pacific Northwest

by CLAIRE RUSH
Updated 5:29 PM EDT, June 10, 2024

"A 'very large' #algal bloom has resulted in “unprecedented levels” of PSP toxins along Oregon’s coast, Matthew Hunter, shellfish program manager for the Oregon Department of Fish and Wildlife, said during a briefing.

"The toxins have accumulated in the shellfish, sickening some people who have eaten them.

"While the factors that create harmful algal blooms are not well understood, certain factors — resulting from both natural processes and human activities — are believed to play a role, according to the National Oceanic and Atmospheric Administration.

“'Studies show that many algal species flourish when wind and water currents are favorable,' the agency says on a webpage dedicated to explaining harmful algal blooms. Some blooms, it says, stem from 'sluggish water circulation, unusually high #WaterTemperatures, and #ExtremeWeather events like #hurricanes, #floods, and #drought.'

"Algae growth can also increase when nutrients used in #fertilizers, mainly phosphorus and nitrogen, flow into bodies of water, according to the agency."

FDA warns on paralytic shellfish poisoning in Pacific Northwest. What to know

The U.S. Food and Drug Administration says consumers should avoid eating shellfish from Oregon and Washington state as they may be contaminated with toxins that cause paralytic shellfish poisoning. The federal warning follows shellfish harvesting closures in both states. Oregon authorities say elevated levels of toxins were first detected in shellfish along its coast on May 17. Since then, state health officials say at least 31 people in Oregon have been sickened. Paralytic shellfish poisoning is caused by a neurotoxin that's produced by algae. Symptoms range from numbing sensation to full respiratory paralysis. According to federal authorities, the Pacific Northwest shellfish industry employs more than 3,000 people and generates more than $270 million a year.

And yeah... Even #Maine isn't immune.

Increasingly early ice-outs on Maine waters open up new environmental problems, experts say

As Maine wraps up one of its warmest winters in recorded history, lakes and ponds across the state are seeing ice-outs earlier than ever. Experts say that's affecting everything from #algae to moose.

by Dylan Tusinski
March 15, 2024

"Earlier ice-outs have severe impacts on everything from algae blooms and trout populations to moose calves and snowmobilers, according to Mark Latti, communications director for the Maine Department of Inland Fisheries and Wildlife.

"One of the most serious symptoms of early ice-outs is the increased frequency and intensity of algae blooms in recent years, according to Whitney King, an environmental chemist and professor at Colby College in Waterville.

"Blooms in recent years have been more severe and widespread, King said. Though algae blooms are a natural occurrence in the spring and summer, they can be toxic for humans and animals, damaging to natural ecosystems, and near-impossible to get rid of.

"Algae blooms’ size and toxicity are often worsened by bright sunlight, warm waters and intense storms, King said. This means that earlier ice-outs are causing earlier and more severe algae blooms, he said.

"'Across the state, we’re seeing an interesting ecological feedback cycle where the physics of the climate control when the open water period starts and ends,' he said. 'If you have shorter ice-in periods, you have longer open water periods, and these longer open water periods are allowing increased growth rates in our lakes — more plankton and less oxygen.

"'Basically, our lakes have a longer growing season and that is not always an ecologically good thing.'"

Why isn't this sounding alarms?!! This is happening globally!

Harmful #algae detected in #OaklandCalifornia's #LakeMerritt could be 'an ominous sign for the Bay'

"Earlier this month, signs posted around Oakland’s Lake Merritt made some joggers stop in their tracks. 'Avoid water contact,' they cautioned in bold letters. 'Harmful algae may be present.'

"The warnings came after a mysterious red substance emerged in the water between the Lake Merritt Sailboat House and the Rotary Nature Center on March 7, as the Oaklandside first reported. Subsequent lab testing by the California Department of Public Health and #SanFranciscoBay Regional Water Quality Control Board last week confirmed the presence of Heterosigma akashiwo in the water — the same species of harmful algae responsible for the Bay Area-wide red tides and mass #FishKills reported in 2022 and 2023.

"But Eileen White, executive officer for the San Francisco Bay Regional Water Quality Control Board, told SFGATE on Tuesday that the current bloom has not reached those levels. 'The good news right now is the lake is looking good, and the red tide we originally observed has dissipated,' she said.

"White added that she runs around the lake just about every day, but did not observe any dead fish in the weeks since the algae was detected. The water has also returned to its usual color, she said.

"'But we’re still trying to understand what caused it. It was a little surprising, because we’ve had so much rain, and we typically associate these harmful blooms with warmer temperatures and less wind activity,' White said.

"'H. akashiwo has been documented across the world, but is most commonly found west of North America in #Japan, #NewZealand and #BritishColumbia, Canada. The species was first observed blooming in the central part of San Francisco Bay in July 2002, and was also spotted near Sausalito in 2004, depleting oxygen levels in the water and causing fish to asphyxiate en masse."

#GoldenAlgae toxin blooms to blame for fish kills at #Saguaro, #CanyonLakes

BY DAMON ALLRED
Mar 17, 2024

PHOENIX — "Golden algae toxin blooms are behind recent #FishKills at Saguaro and Canyon lakes, the Arizona Game and Fish Department confirmed Friday.

"Golden algae, which can be harmful to gill-breathing animals such as fish, has affected Salt River chain lakes — Saguaro, Canyon and Apache — since 2003, the AZGFD said in a press release.

"Over the years, humans and other non-gill-breathing wildlife have not displayed negative health impacts after coming into contact with a golden algae toxin bloom.

"Hundreds of fish — mostly of the threadfin shad species — were observed to be dead or dying. Other species such as largemouth bass, bluegill and catfish were also affected."

I'm seeing a pattern here...

"'On March 14, the Minnesota Department of Natural Resources responded to a fish die off on Traverse Lake in southwest #Minnesota near the city of Wheaton. DNR staff collected fish samples and checked dissolved oxygen in the water. The cause of the die off appears to be gas supersaturation trauma, also known as gas bubble disease, likely the result of an #AlgaeBloom in the lake,' a spokesperson for the Minnesota Department of Natural Resources told Newsweek in an email."
