‘We are perilously close to the point of no return’: climate scientist on Amazon rainforest’s future

> At what level will the Amazon hit a tipping point?
We estimate that a tipping point could be reached if deforestation reaches 20-25% or global heating rises to 2.0-2.5C [above preindustrial levels].

> What is the situation today?
It is very, very serious. Today, 18% of the Amazon has been cleared and the world has warmed by 1.5C and is on course to reach 2.0-2.5C by 2050.

The Guardian · ‘We are perilously close to the point of no return’: climate scientist on Amazon rainforest’s futureBy Jonathan Watts

We are destroying our only home.

The 🌍 #Earth — once wild, vibrant, and full of life — is now choking under the weight of our #pollution, our #greed, and our silence.

The #climatecrisis is not a distant threat. It’s here. In the rising seas, in burning forests, in vanishing species, in every breath of toxic air.

We cannot keep turning away. We are not separate from #nature — we are part of it. And when we destroy it, we destroy ourselves.

This is a call to action. Not tomorrow. Not “one day.” Now.

🌱 Reduce. 🌿 Restore. 🛑 Resist.
Speak up. Vote for the planet. Support #climatejustice. Protect what remains.

Because there is no planet B.
Because #sustainability is not a trend — it’s survival.

Thank you.

Ursula von der Leyen amputates the Green Deal to save its life

Last year’s European election reshaped #EU politics. The Commission president must acknowledge a new alternative right-wing majority even as she fights to preserve her signature political achievement.
Europe’s #GreenAgenda is under attack from a motley coalition of corporate #lobbyists, #FarRight rabble rousers and von der Leyen’s own political family, the center-right European People’s Party (#EPP).

Von der Leyen, the top EU executive and a medical doctor before she entered politics, is adamant she wants to save the patient, even if that means removing some of its minor limbs.

POLITICO · Ursula von der Leyen amputates the Green Deal to save its lifeBy Karl Mathiesen

Slipped up and posted comments on three channels on YouTube re. Washington Post/Joe Rogan climate fallacies. Linked to sources, quoted scientists they’re referring to, and said the motives of the WP and Bezos should be questioned. Nothing personal or attacking. Shadow banned.

"Already, international climate scientists have called out the Prime Minister for ignoring scientific evidence by exploring dodgy accounting tricks for measuring methane emissions from livestock. It is the first time in Luxon’s political or business career that he has made the front page of the Financial Times - and it was humiliating. He should expect more international criticism to come."

On June 11, the Toronto Community Bikeways Coalition set up cameras on the second floor of Curbside Cycle and counted every vehicle that passed over an imaginary line in the road during peak travel times. While Doug Ford claims that only 1.2% of Torontonians commute by bike, the study showed that during the afternoon rush hours, bikes, including e-bikes and other micro mobility devices, represented over 50% of all vehicular traffic.

@tobeB

I am deeply cynical of #CarbonCredits and offsetting. It’s a licence to carry on ‘business as usual’, with minimal integrity attached to company claims. Do any of the players who use these schemes to amp up their green credentials actually do their own due diligence on the integrity of these schemes?Of course not, because they don’t care about the #ClimateCrisis, just their bottom line and selling to the next generation of consumers.

"#Florida's housing market is experiencing something it hasn't experienced since 2008 - a correction is in full steam.

🚨Inventory is exploding, sellers are cutting prices, & we now have >181K homes for sale.

That's up 62% from the long-run average.

#Jellyfish Keep Attacking #NuclearPowerPlants

By Gabriel Geiger
November 2, 2021

"Jellyfish are continuing to clog the cooling intake pipes of a nuclear power plant in Scotland, which has previously prompted a temporary shutdowns of the plant.

"The #TornessNuclearPowerPlant has reported concerns regarding jellyfish as far back as 2011, when it was forced to shut down for nearly a week—at an estimated cost of $1.5 million a day—because of the free-swimming marine animals.

"In a short comment to Motherboard, #EDFEnergy, which runs the Torness plant, said that 'jellyfish blooms are an occasional issue for our power stations,' but also said that media reports claiming the plant had recently been taken offline because of jellyfish are 'inaccurate.' '[There were] no emergency procedures this or last week related to jellyfish or otherwise,' a spokesperson said. [Um, did they previously work for #TEPCOLies?]

" 'Like many other seaside power plants, the Torness plant uses seawater to prevent overheating. While there are measures in place to prevent aquatic life from entering the intake pipes, according to the #BulletinOfTheAtomicScientists, they are no match for the sheer number of jellyfish that come during so-called 'jellyfish blooms.'

" 'Usually, screens prevent aquatic life and similar debris from being drawn into the power plants’ cooling system,' the Bulletin of the Atomic Scientists wrote in a 2015 blog post. 'But when sufficiently large volumes of jellyfish or other aquatic life are pulled in, they block the screens, reducing the volume of water coming in and forcing the reactor to shut down.'

"While the case in Scotland has once again spotlighted concerns regarding the jellyfish and potential power plant shutdowns, these concerns are far from new. In 2008, a swarm of jellyfish shut down a nuclear power plant [#DiabloCanyon -- which had another incident in 2024] in #California, and three years later the same occurred at a plant in Japan [#Shimane]. In 2017, jellyfish clogged a power plant in Israel [#Hadera]."

VICE · Jellyfish Keep Attacking Nuclear Power PlantsBy Gabriel Geiger

#Jellyfish are taking over the world – and #ClimateChange could be to blame

"For 500 million years, jellyfish have been part of the maritime #ecosystem, but now they’re poised to take over the earth.

"They have no brain, no eyes, no spine, not even blood, but they have a remarkable capacity to reproduce and can pack an impressive sting, both literally and figuratively.

"Most recently, vast numbers of bluebottle jellyfish were pushed ashore by unusually strong winds and spells of hot weather in #QueenslandAustralia, stinging thousands of people and forcing the closure of popular swimming spots. About 13,000 stings were recorded in the past week.

"In June last year, over the course of just one week, over 1,000 people were stung in Volusia County, #Florida, following a period of exceptionally prolific jellyfish blooms. The explosion in their numbers has been attributed to warming seas and even increased pollution; unlike many other marine creatures, jellyfish can cope with reduced oxygen levels.

Small but deadly – at least some of the time

"Typically, jellyfish range in size from 1cm to 40cm. But they can be significantly larger – the #LionsManeJellyfish, for example, can reach 1.8 metres wide, with tentacles over 15 metres long.

"For the most part, the sting of a jellyfish is more unpleasant than it is harmful. The pain comes from venom delivered via millions of microscopic barbs in the creatures’ tentacles. Most jellyfish stings will only have a localized effect on the victim – redness, swelling, and discomfort where the barbs make contact with the skin.

"Some, however, will prompt a systemic, whole body, reaction. These may take several hours to emerge and can include symptoms such as headaches, nausea and drowsiness.

"In rare cases, the sting can be fatal. This is true of the #BoxJellyfish, which is spreading into waters that had previously been too cool to support it; its venom causes a severe reaction that can cause death within minutes.

A force of destruction

"But these booming jellyfish populations are doing far more harm than ruining people’s trips to the beach. In fact, the scope of their disruption has extended far beyond the water’s edge.

"In 2011, both reactors at the #TornessNuclearPowerPlant in #Scotland were shut down after an invasion of jellyfish started blocking the cooling filters. Two years later, the jellyfish struck again – this time in #Sweden. They forced the closure of the #OskarshamnNuclearPowerPlant, which contains the world’s largest boiling-water reactor.

"The island of Luzon, home of the Phillippines’ capital Manilla, suffered a blackout in 1999 due to jellyfish, and in 2006 the #USSRonaldReagan, a nuclear-powered aircraft carrier, was brought to a standstill by thousands of the little creatures. And while these events may stand out as exceptions, they are increasing in both scale and frequency.

"From sea-bed diamond mining in Namibia to salmon farming in Ireland, even jeopardising the sustainability of beluga caviar farming in the Caspian Sea, jellyfish are as destructive as they are abundant. And that abundance is being caused by a variety of factors, many of which are related to human activity.

Some like it hot

"Over the last hundred or so years, the average surface temperature of the world’s seas has risen by about 0.9°C. As the oceans get warmer, marine animals are able to spread into areas that had historically been too cold. Oxygen levels in the sea have fallen by around 2% over the last 50 years, due to rising temperatures and #pollution [including #NuclearOceanDumping, which reduces oxygen levels]

"Jellyfish can thrive in areas with lower oxygen levels, where other animals suffer. But there are other factors at work, too. Fishing has depleted the global stocks of some of the jellyfish’s natural predators – such as #tuna and #swordfish – and some they compete with for food – such as anchovies. With more food and fewer predators, some jellyfish populations can grow unchecked.

"In the #BlackSea, unchecked population growth is precisely what’s happened. #AnchovyFishing in the region had caused harm to the Black Sea’s ecosystem by the time stowaway jellyfish made the journey there from the eastern seaboard of the USA. Most likely transported in the ballast water of ships that made the crossing, 1982 saw the arrival of the warty comb jelly. By 1990, there were 900 million tons of them in the Black Sea.

"There are believed to be around 200 different species of jellyfish, not all of which can sting, and some are considered edible. This could offer one potential, and creative, approach toward dealing with an over-abundance of jellyfish – co-opting them onto our dinner plates." [That's one way to deal with invasive species -- eat them into extinction!]

#Jellyfish are taking over the #oceans due to #ClimateChange

"Climate change and human activity have impacts that ripple through all ecosystems. Their negative effects can lead to population imbalances across these various #ecosystems. While populations of many species are declining because they are unable to survive the rapid #EnvironmentalChanges, this is often not the case for venomous aquatic life like #SeaUrchins and jellyfish. In fact, these populations are increasing across the globe, with damaging effects on other living #AquaticOrganisms and human activity."
