Earth’s oceans just broke a heat record. The implications will be massive
By Anthony Edwards, Aug 23, 2026
"Earth’s oceans were warmer than any day in recorded history Friday due to a combination of long-term human-caused global warming and short-term effects of #ElNiño.
The average sea surface temperature of 21.1 degrees Celsius, or 70 degrees Fahrenheit, breaks the old record of 21.09 degrees Celsius set many times in early 2024 during the most recent El Niño.
" 'There is quite a big certainty that sea surface temperatures globally are now higher than even the last warm period before the last ice age,' #LeonSimons, a climate systems analyst and executive director of the #ClubOfRome Netherlands, said during a webinar Sunday.
"Measurements are based on data from satellites, buoys and ships between 60 degrees south and 60 degrees north latitude and analyzed by the Copernicus Climate Change Service. Daily measurements date back to 1979, though July sea surface temperatures were the warmest month globally since at least 1854."

😢 A #MarineHeatWave caused seabird deaths off California. El Nino could worsen the die-off
‘We don’t know how bad this is going to get’
By JULIE WATSON
Updated 1:25 PM EDT, July 1, 2026SAN DIEGO (AP) — "Within minutes of walking on a #SanDiego beach, marine ornithologist Tammy Russell found the feathered carcasses — one after another.
Some were mixed in with washed up kelp. Others were under rocks."Each month, scientists and volunteers conduct surveys of dead #seabirds and find what Russell describes as a grim assessment of the impact of a massive marine HeatWave that has lingered for months off parts of the California coast.
"The surveys that have been carried out by various organizations for decades help build a baseline of information on beached sea life to detect threats and their impact.
"Many seabirds, including California #BrownPelicans, #loons and #grebes, starved to death in recent months as record-setting ocean temperatures decreased the band of cold, nutrient-rich surface water where #krill, #anchovies and #sardines thrive near the shore, said Russell, a postdoctoral scholar at the University of California, San Diego, Scripps Institution of Oceanography.
"We’ve been seeing #cormorants walk to shore and then just die within the hour. I mean one time it happened within 15 minutes, and I’ve never seen that before,” Russell said. 'That has been heartbreaking for me and we’re seeing this happening across the whole coast.'
"Scientists fear the die-off could worsen with the recently formed El Nino, the natural warming of parts of the central Pacific that alters weather worldwide and spikes global temperatures."

#Algal #Toxins emerge as a new concern in #Alaska’s Northern Bering Sea
Locals who depend on the sea for food and culture are trying to understand the risks to traditional foods and wildlife populations in a region undergoing myriad changes
by Yereth Rosen, Alaska Beacon, May 31, 2026 via #ICTNews
Excerpt: "For countless generations, people of the #BeringStrait region have relied on the food they harvest from the sea without worrying about #HarmfulAlgalBlooms [#HABs] that threaten seafood eaters in warmer and more southern latitudes.
"Now, as the Northern Bering Sea undergoes cascading effects of a warming climate, algal risks pose a new challenge.
"The change has been dramatic.
"And it has prompted a change in the way #Nome youth grow up learning about collecting food from the waters around their home. In early April, Nome high school students traveled to Bethel with their science teacher, where they presented their research at the Western Alaska Interdisciplinary Science Conference held by Alaska Sea Grant.
"Algal toxins were present, at very low but detectable levels, in fish they eat.
"Sophomore Audrey Bruner-Alvanna was among the group of student researchers. She said young people are concerned about algal blooms, which proliferate in warmer conditions, and their potential effects on wild food resources.
" 'Because, you know, as the climate changes, as the world gets warmer and stuff, there’s going to be more of these toxins and stuff during summer,' she said. 'I feel like a lot of people that I’ve talked to have been wondering about how our subsistence is going to change in the future based on all of that.'
"The student research came about after one of the nation’s densest and biggest concentrations of toxin-producing Alexandrium algae ever documented burst forth in the waters of the Bering Strait region in 2022.
"Until the appearance of the 'massive bloom, the most toxic bloom, the longest-persisting bloom in the U.S.,' local people barely knew what harmful algal blooms or #Alexandrium are, said Emma Pate, president of the Nome Eskimo Community, the local tribal government.
" 'So we had to figure things out and learn really fast,' Pate said during an October 'Strait Science' presentation hosted by the University of Alaska Fairbanks’ Nome campus."

More victims of #ClimateChange and #WarmingOceans. Also, #KrillHarvesting has got to STOP!
Scientists Alarmed as #Whales Suddenly Going Silent
"When you really break it down, it’s like trying to sing while you're starving."
Aug 1, 10:27 AM EDT by Victor Tangermann
"Researchers are alarmed after noticing a significant drop in the number of vocalizations from #BlueWhales.
"As National Geographic reports, scientists used specialized underwater hydrophones, meaning the aquatic version of microphones, to record and trace the sounds of marine life, allowing them to analyze the impact human activity is having on various species.
"However, as detailed in a study published in the journal PLOS One, devastating heat waves have triggered worrying changes over the past decade, allowing #ToxicAlgae to bloom and undermine food sources for whales.
" 'It caused the most widespread poisoning of marine mammals ever documented,' coauthor and Monterey Bay Aquarium Research Institute biological oceanographer John Ryan told NatGeo. 'These were hard times for whales.'
"As a result, blue whale vocalizations dropped by almost 40 percent, according to the study, with populations of #krill and #anchovy collapsing.
" 'When you really break it down, it’s like trying to sing while you're starving,' Ryan explained. 'They were spending all their time just trying to find food.' "

Six rare #sawfish deaths in 7 days have scientists baffled amid bizarre #Florida fish behavior
“There is no concrete, conclusive proof of what is happening yet and that is still to be determined, which is quite terrifying.” said Gregg Furstenwerth, a lifelong diver in the Florida Keys. “If it continues, it is going to be the end of this #ecosystem as we know it.”

"Most tests for toxins have been negative, but scientists have seen an unusually high number of #algae called gambierdiscus that can produce a wide variety of #neurotoxins that can be harmful to fish and dangerous to humans.
#Gambierdiscus is normally found in tropical and subtropical waters all around the world, but the algae can grow quickly when waters are warmer than usual. The climate crisis has brought record hot temperatures to the waters around southern Florida."
