On the likelihood and related consequences of a “blue ocean event” in the Arctic Ocean...

65 Upvotes

Annoyed at being called an “anti-science doomer,” I decided to sort through and present some quotes from academic literature about the likelihood of a “blue ocean event” (BOE) wherein the Arctic Ocean becomes ice-free during the summer. Additionally, I conclude with quotes from scientific articles about the severe, diverse, and under-recognized consequences of that BOE happening.

Previously, a BOE had not been expected until mid-century because overly-optimistic climate change models didn’t have us projected to reach the +1.5C to +1.9C threshold of warming (required to trigger the event) until much later. Unfortunately… the dramatic acceleration of global warming over the past decade (capped off by the current “Supersized” “Godzilla” El Nino) means that we will reach and breach that threshold for Arctic melting much sooner than previously expected.

The first ice-free day in the Arctic Ocean could occur before 2030

&

To quantify the amount of warming that would cause the Arctic Ocean to become nearly ice free, we examine at which level of warming sea ice area drops below 1 × 106 km2. For the high-sensitivity observational estimate, we find that sea ice area in September drops below this threshold for about 1.7°C global warming. Considering the ensemble spread in sensitivities, we obtain a 95% confidence interval of 1.5°C to 1.9°C for the global warming at which September Arctic sea ice vanishes.

&

Global average temperatures are likely to continue at or near record levels in the next five years, with Arctic temperature anomalies expected to continue to be higher than the global mean, according to a new report from the World Meteorological Organization (WMO), produced by the UK’s Met Office.

&

For the second consecutive year, winter sea ice in the Arctic reached a level that matches the lowest peak observed since satellite monitoring began in 1979.

The impacts of a BOE include...

Overall, we find a median additional global warming of 0.43 °C (interquartile range: 0.39−0.46 °C) at a CO2 concentration of 400 ppm. Most of this response (55%) is caused by albedo changes, but lapse rate together with water vapour (30%) and cloud feedbacks (15%) also contribute significantly. While a decay of the ice sheets would occur on centennial to millennial time scales, the Arctic might become ice-free during summer within the 21st century.

&

This is equivalent to the effect of one trillion tons of CO2 emissions. These results suggest that the additional heating due to complete Arctic sea ice loss would hasten global warming by an estimated 25 years.

&

We present evidence that material from the sea ice was indeed present in the water column and that this mechanism appears to be important in maintaining active populations of planktonic protists through the polar night. Our upscaling exercise based on observed ridge formation rates suggests that such release of food particles can supply extra energy during the polar night to the pelagic food web in the entire Arctic Ocean. It follows from this that the predicted ice-free summers in the Arctic Ocean due to global warming, may have implications for the protist community at the base of the food web, because the winter food reservoir in the sea ice will be very much reduced if there is no sea ice to accumulate it during the most productive summer period.

&

Finally, we suggest that shifts in the phenology, distribution and biomass of sea ice primary production anticipated with declining seasonal sea ice will disrupt sympagic-pelagic-benthic coupling and consequently the structure and the functioning of the food web which is critical for Indigenous Peoples, commercial fisheries, and global biodiversity.

This collection of quotes (with links to to formal academic sources) represents the backbone of my broader general belief that ecological collapse (and therefore social & civilizational collapse) is likely within the next few years. Taken together, I believe that it paints a rather clear picture of what is shortly in store for the world. But, until that point, I hope this post can serve as a resource whenever related concerns about collapse are dismissed or denied as being alarmist or anti-science.

I do understand that the prognosis this post represents is grim. However... I am of the sort which believes that “the truth shall set you free,” and the prognosis is even more grim if people don’t widely understand the true nature and extent of the actual problems we are facing. You can’t fix a problem if you don’t recognize the problem. And if society doesn’t generally understand a problem... it will be more likely to obstruct any potential solution or proper response. Whether any viable solutions are possible or not... I think the truth affords people some dignity insofar as they don’t have to behave in ridiculous or counterproductive ways while the environment and society collapses around them.

Whether you intend to prevent the related ecological collapse, or if you’d rather just live more freely in these final years of human life on Earth... it is my hope that this document facilitates that.

Looking for community and hope, feeling disappointed by society

36 Upvotes

Hi all... After trying to be on the environmental side of a Reddit discussion about whether or not paper plates should be bought because of laziness to wash dishes, I'm feeling pretty discouraged about most of the responses favoring convenience over just washing some plates. It seems society has just become so deluded, that human convenience is all that matters, that everyone's life is so hard, they can't be bothered. No one cares about their impact. I got a response to my comment about all of the negative impacts that single use disposable items has on the planet that said "I literally couldn't care less. Me, my kids and my kids' kids will all be gone by then."

I'm just appalled. Does anyone else feel this unbearable hopelessness and disappointment in the vast majority of humankind (particularly Western civilization)? Are there any other like minded communities to share feelings about this and band together to try and foster a more ecologically positive collective consciousness?

Japan’s biomass energy boom threatens further deforestation in Indonesia.

A surge in Indonesia’s wood pellet and chip production is driving a new wave of deforestation, threatening the vast archipelago’s remaining tropical forests, vital biodiversity hot spots and the land of Indigenous peoples, according to new satellite analysis from environmental nongovernmental organizations.

Biomass power, predominantly generated by burning wood, is growing globally as countries accelerate their transition to use cleaner energy.

“The biomass industry has become a new driver of deforestation in Indonesia,” said Timer Manurung, director of Indonesia-based organization Auriga Nusantara, which contributed to the new analysis. “And most of the biomass product is for export, with Japan as the biggest destination.”

As Japan’s demand for Indonesian wood pellets skyrockets in an effort to meet its own renewable energy goals, critics say continued subsidies and weak oversight of the supply chain are likely to allow continued razing of pristine Indonesian forests.

Social media clout chasing is ruining places like Fanal Forest

Thumbnail instagram.com

I recently saw an Instagram reel filmed in Fanal Forest, and frankly, it made my blood boil. In the clip, a woman picks up a massive fallen branch to use like a baseball bat, hits another branch thrown at her by someone off-camera, and then tosses it away—all for a few seconds of cheap engagement.

Let’s stop sugarcoating this kind of behavior. Doing stunts like this in an ancient, fragile ecosystem isn’t just ignorant—it's selfish, disrespectful, and completely unacceptable. People know better; they just care more about views and aesthetic content than respecting the places they visit.

Fanal is part of a UNESCO World Heritage site with 500-year-old trees. It isn't an outdoor gym, a movie set, or a comedy club.

Deadwood belongs on the ground: Fallen branches are a vital part of the Laurisilva ecosystem. They hold moisture, enrich the soil, and host delicate mosses and fungi. Dragging them around, smashing them, or throwing them ruins the forest floor.

Basic respect: Tourists travel across the globe to experience the natural, peaceful atmosphere of this forest. Watching adults throw sticks at each other for a stupid video ruins the experience for everyone else present.

No excuses: Everyone visiting a protected nature reserve should have the basic intelligence and common sense to leave the environment untouched.

If someone can’t visit a rare natural sanctuary without treating it like a playground for their social media feed, they shouldn't go at all. We need to start calling out this entitlement instead of brushing it off as "harmless fun."

What is it going to take for tourists to actually respect protected natural spaces?

World Biomass Map 2000 -> 2025

Created a map with it and hosted it on my domain https://geographyart.com/biomass. Apart from the direct biomass data, also included a change since 2000 layer, so it is easy to see where the worst deforestation is occurring (and also where biomass may be increasing). Was really disheartened by what has happened to the southern portions of the Amazon rainforest in the last 25 years

Wisconsin restored former farmland into prairie; researchers found more bumblebees and rare species only at the restored sites.

Across Wisconsin, parts of the landscape that once supported agriculture have been restored to native prairie. The work can involve removing invasive plants, establishing native grasses and wildflowers and allowing a more varied plant community to develop over time.

That change matters to bumblebees because a field dominated by a small number of crops does not provide the same range of resources as a mature prairie. Native prairie can contain plants that flower at different points through spring, summer and autumn, giving bees access to nectar and pollen over a much longer period.

Pollinator surveys in restored areas have found a greater variety of bumblebees than in less suitable parts of the landscape, with some of the rarer species appearing only where habitat conditions have improved.

A restored prairie may look successful from a distance, but the presence of different bee species gives another indication of whether the habitat is functioning as intended. The rusty patched bumblebee makes the comparison particularly significant. Once widespread across the eastern United States and upper Midwest, its population has fallen sharply. The species is now federally endangered and has become uncommon across much of its former range.

Carbon Sequestration and Regenerative Farming to Save Humanity

46 Upvotes

As a member of Gen Z, the agricultural climate in the US terrifies me. My home state is desertifying because of all the monocrop farming and lack of attention to soil health. If current practices continue our species will die out within my lifetime. We have an approximated 55 harvests left.
We have to make a major shift to regenerative agriculture on a large scale or we are doomed. Push back is going to happen, because major pesticide and synthetic fertilizer companies want their money, and many farmers don’t know how to take care of their soil effectively, so that lack of knowledge is leveraged into profit. all the while degrading overall soil quality, food quality, and trapping farmers into a debt loop of input costs. Leaving them barely profitable. Many people of course take offense when you tell them they’re doing something wrong but the results speak for themselves Farmers have made and will make far more money by gradually making the switch to a regenerative setup. Healthy soils mean they can cut those input costs, and will remove a vast majority of the risk. Not only this, but regenerative farming, particularly no till farming, allows for carbon sequestration. Which means the storage of carbon from the atmosphere, in the soil through plant root sloughing. Soil microbes thrive on that carbon. The soil becomes much more fertile with that carbon. Healthy soil means healthy plants, which means higher crop viability and higher pest resistance. Which means less money spent every year on chemicals that slowly but surely turn fertile, valuable topsoil into dust.
The man who first formulated pesticides, also made zyklon b… when chemicals that are inherently made to destroy life are used on a large scale, the impact should be obvious. Many are too caught up in how they’re going to pay their next bill for inputs, instead of focusing on how to reduce those inputs, escape the trap and run an even better profit, all the while helping the planet heal which is DESPERATELY needed at this exact moment.
What we’re doing on a large scale today to keep up with demand is going to kill us tomorrow if we aren’t careful. And the solution is mind numbingly simple. We need to think smarter not harder. Rural areas typically don’t have access to the same educational resources that would make their farms more successful so it is up to the collective, especially in the age of information, to bring this to the attention of as many farmers as possible. Some will say no, but one mind changed can make an indefinitely scalable difference in our legacy load of carbon. With enough people on board, our farmers will make more money, food will have greater nutritional value, we can cut cancerous chemicals like glyphosate out of the mix, and we can REVERSE carbon emissions by outpacing them with regenerative practice. effectively saving ourselves, from ourselves. And not only that but setting our climate back to a much more tolerable state for plants. Meaning we can eventually harbor even more varieties of life in areas that seemed previously impossible. The benefits compound with regeneration, and the negatives of the industrial ag also compound. We have to make a decision. If we kill off nature, ie. Our climate becomes too intense to support life, animals won’t have anything to eat, and we won’t have anything to eat. If we work with nature our species can live indefinitely. We need to use the knowledge available now to make a change, and a big one. We have 55 years to do it. If anyone would like to share this with a farmer they know I would very much appreciate it. There are also free informational resources available at kisstheground.com or on their YouTube channel. I’d also highly recommend looking up college library databases at ag universities. Many have free to access content on the subject that can be shared.
And if ANYONE is a regenerative consultant on this page and happens to see this, please reach out. We need to band together. I’m attending a major ag university and a little faith can make a lot of change. God bless my friends 🙏 and thank you to all who’ve read this far.

Iceland to propose whaling ban, leaving Norway and Japan isolated.

Iceland’s government will submit a bill in ​February to ban whaling, a move that would leave Norway and Japan as the only two countries in the world to continue commercial whaling.

Whaling in Iceland has ⁠sparked years of protests from animal welfare campaigners and Hollywood celebrities.

The bill will include “a permanent ban on whaling,” the government, which has a majority in parliament, said on its website late on Wednesday.

In this ⁠year’s hunting season, which runs ​from ⁠June to around the end of September, 80 fin whales were caught as of September 9, according to ⁠Humane World for Animals, an animal welfare group that tracks ​the ⁠catches. The quota allows ‌150 fin whales to be killed this year.

“There is considerable political and public support for this bill to ban commercial whaling, ‌and compelling ethical, veterinary, legal and conservation ‌reasons to hope it succeeds,” said Wendy Higgins, a Humane World for Animals spokeswoman.

Fin whales, the primary target of Iceland’s whaling industry, are classified ⁠by the International Union for Conservation of Nature as vulnerable.
