MagpieblogRed cedars and more than a dozen other native fir trees in the Pacific Northwest are dying as their ranges move uphill in response to warming temperatures caused by climate change. The die-off is also affecting Douglas firs, the region's most important commercial tree species.

Climate change is hastening the demise of Pacific Northwest forests
Iconic red cedars — known as the “Tree of Life” — and other tree species in the Pacific Northwest have been dying because of climate-induced drought, researchers say. In recent years, at least 15 native tree species in the region have experienced growth declines and die-offs, with 10 linked to drought and warming temperatures, according to recent studies and reports. Many researchers say these drought-driven die-offs are the beginning of a much larger and long-predicted shift in tree growing ranges due to climate change. Trees have growing ranges largely determined by climate factors, namely moisture and temperature.
DoomsdaysCWA climate-related mass #dieoff leaves over 100 tons of dead #fish collecting at a Greek port

VOLOS, #Greece (AP) — "More than 100 tons of dead fish were collected in and around the port of #Volos in central Greece after a mass die-off linked to extreme weather fluctuations, authorities said Thursday.
"The dead #FreshwaterFish filled the bay 320 kilometers (200 miles) north of #Athens, and nearby rivers. Water levels were swollen by #floods in 2023, followed by months of #SevereDrought.
"The die-off has hit local businesses along the seafront, reducing commercial activity by 80% in the past three days, according to Volos’ Chamber of Commerce.
"Fishing trawlers have been chartered by the regional authorities, along with earthmovers, to scoop the dead fish out of the sea and load them onto trucks bound for an incinerator.
"The fish came from #LakeKarla in central Greece, a body of water drained in the early 1960s and restored in 2018 to combat the effects of drought.
“'There are millions of dead fish all the way from Lake Karla and 20 kilometers (12 miles) eastward,' Anna Maria Papadimitriou, the deputy regional governor of the central #Thessaly area, told state-run television.
"'Right now, there is a huge effort underway to clean up the millions of dead fish that have washed along the shorelines and riverbanks … an effort that involves multiple contractors,' she said.
"Water levels rose abruptly in fall 2023 during a #DeadlyStorm that caused extensive flooding in central Greece, but have since receded due to low rainfall and successive summer #heatwaves ."

A climate-related mass die-off leaves over 100 tons of dead fish collecting at a Greek port
Authorities say more than 100 tons of dead fish have been collected in and around the port of Volos, in central Greece, following a mass die-off linked to extreme climate fluctuations. The dead freshwater fish filled the bay, 320 kilometers north of Athens, and nearby rivers after water levels were swollen by floods last year, followed by months of severe drought. Fishing trawlers have been chartered by the regional authorities, along with earthmovers, to scoop the dead fish out of the sea and load them onto trucks bound for an incinerator.
A 'catastrophe' in [#Florida's] #LowerKeys: Summer #heatwave wipes out iconic #ElkhornCoral 😢
WLRN Public Media | By Jenny Staletovich
Published August 16, 2024
"The blistering summer heat wave that hammered South Florida’s coral reefs last year wiped out the last wild stands of its iconic elkhorn coral in the Lower Keys, the National Oceanic and Atmospheric Administration [#NOAA] announced this week.
"The deaths amounted to a 77% loss in genetic diversity needed to help sustain a vanishing coral that once blanketed Florida reefs.
"That’s left scientists who have been working for decades to restore the antler-shaped coral struggling with what to do next.
"'The community wasn't expecting this kind of off-a-cliff #catastrophe,' said Ilsa Kuffner, a research biologist with the U.S. Geological Survey. 'There were already declines that were pretty pronounced in the last 20 years. So this was a big ratcheting down of that.'
"When the heat wave hit, scientists were already struggling to keep up with efforts to grow and plant coral on an ailing reef under attack from a new disease that cropped up in 2014 near Miami. That disease had intensified restoration efforts and focused work on breeding a new resilient coral that could both tolerate heat and disease. The unexpected heat wave was like a fire alarm.
"By July, prolonged heat that began rising three months earlier was wilting coral, causing them to begin expelling their life-sustaining algae, turn white and die."

A 'catastrophe' in the Lower Keys: Summer heatwave wipes out iconic elkhorn coral
Despite the dedicated efforts of scientists, the National Oceanic and Atmospheric Administration announced this week that no wild elkhorn — a species valued for its tough wave-shredding antlers and listed as an endangered species — could be found south of the Upper Keys.

#Florida’s Record-Breaking Sea Temperatures Affecting #Coral
Story by Catrin Einhorn and Jason Gulley, July 31, 2023
"With #climateChange ravaging Florida’s beloved reef, people who’ve devoted their careers to restoring coral in the sea are now racing to get it out of the water, to tanks on land. They’re pushing through feelings of grief and fear over the future to save what genetic material and young corals they can. But in the background, an existential question looms: How can they restore reefs if the ocean is getting too hot for coral to live there?
"While marine #heatwaves occur naturally, the eye-popping sea temperatures recorded off the Keys this month (one reading hit 101 degrees Fahrenheit, or just over 38 Celsius) have been made worse by global warming, according to the National Oceanic and Atmospheric Administration. The world’s oceans have absorbed 90% of the additional heat unleashed by people burning fossil fuels and razing forests. Currently, about 44% of the #global #ocean is in a #heatwave.
"The mass coral bleaching happening throughout the Keys is the most severe in the state’s history, Derek Manzello, the coordinator of NOAA’s Coral Reef Watch program, said. Surveys over the next few months are needed to understand how much coral has died.
"'I fear for the worst,' he said."

This is all quite normal, I am sure. #Texas #fish #dieoff CBS: Beach crews spent the weekend clearing up thousands of dead fish along the Texas Gulf Coast, shore officials said. The fish began washing up on Friday because of "a low dissolved oxygen event" https://www.cbsnews.com/news/thousands-dead-fish-texas-gulf-coast-quintana-beach-oxygen/
Thousands of dead fish wash up along Texas Gulf Coast
Low oxygen levels in the water caused thousands of dead fish to wash up along the shores of the Texas Gulf Coast over the weekend, officials said.
🇺🇦 Sean Prophet ⚛This idea that's been gaining currency that "#populationcollapse" due to declining birth rates is a "problem," is beyond perverse.
#Overpopulation remains near the top of the list of world crises. It's only overshadowed by #ClimateChange which is partially the *result* of past overpopulation.
We're deeply into population #overshoot in terms of having crashed through about 5 of the 9 #planetary boundaries. So yes, there will be a population collapse and it won't just be from declining birth rates.
It's likely to be far more unpleasant than that--competition over scarce resources leading to war, mass migrations, and famines.
#dieoff is the appropriate term. And it applies to humans just as any other species that's overfilled its ecological niche.
It would be possible for Earth to support 10 billion or more people, if we lived more sustainably. But that's way easier said than done. People want what they want and they will kill and die to get it. To say nothing about the devastating impacts of global income inequality.
We should be so lucky, as to "only" face a crisis of a greying population and not enough young people. If that were the case, #automation would be able to handle any worker shortages, provided we put in place the wealth redistribution and basic income needed to offset the decline of compensated labor.
What's actually likely to happen is we'll continue to make all the wrong decisions due to the #fascist / #nationalistic political insanity that's sweeping the globe.
We're out of runway to keep making repeated bad decisions, without consequences that will be terribly disruptive to #civilization as we once knew it.

Please read; the most important piece I've written. Mass poisoning has suddenly killed off most sea life for 30 miles by the Tees. The govt claims it's natural; ind scientists warn it's manmade. The govt is desperate not to inquire too deeply as its freeport policy is at stake.
