    "Given the sheer enormity of climate change, it’s okay to be depressed, to grieve. But please, don’t stay there too long. Join me in pure, unadulterated, righteous anger."


    "I don’t want your hope. I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act. Once you start to act, the hope is everywhere."

    "Our best scientists tell us insistently that a calamity is unfolding, that the life-support systems of the Earth are being damaged in ways that threaten our survival. Yet in the face of these facts we carry on as usual."

    “We’ve got to stop burning fossil fuels. So many aspects of life depend on fossil fuels, except for music and love and education and happiness. These things, which hardly use fossil fuels, are what we must focus on.”

    A nejde o to, že na to nemáme dostatečné technologie, ty by na řešení použít šly, ale chybí nám vůle a představivost je využít. Zůstáváme při zemi, přemýšlíme až moc rezervovaně. Technologický pokrok to sám o sobě nevyřeší. Problém jsme my, ne technologické nástroje.

    Rostouci hladiny oceanu, zmena atmosferickeho proudeni, zmeny v distribuci srazek a sucha. Zmeny karbonoveho, fosforoveho a dusikoveho cyklu, okyselovani oceanu. Jake jsou bezpecnostni rizika a jake potencialni klady dramatickych zmen fungovani zemskeho systemu?

    Groundswell Part 2 : Acting on Internal Climate Migration
    https://openknowledge.worldbank.org/handle/10986/36248

    This new report builds on the scenario-based modeling approach of the previous Groundswell report from 2018, which covered Sub-Saharan Africa, South Asia, and Latin America. The two reports’ combined findings provide, for the first time, a global picture of the potential scale of internal climate migration across the six regions, allowing for a better understanding of how slow-onset climate change impacts, population dynamics, and development contexts shape mobility trends. They also highlight the far-sighted planning needed to meet this challenge and ensure positive and sustainable development outcomes. The combined results across the six regions show that without early and concerted climate and development action, as many as 216 million people could move within their own countries due to slow-onset climate change impacts by 2050. They will migrate from areas with lower water availability and crop productivity and from areas affected by sea-level rise and storm surges. Hotspots of internal climate migration could emerge as early as 2030 and continue to spread and intensify by 2050.

    Zimbabwe's climate migration is a sign of what's to come | MIT Technology Review
    https://www.technologyreview.com/2021/12/17/1041315/climate-migration-africa-zimbabwe/

    Mutero is just one of the 86 million people in sub-Saharan Africa who the World Bank estimates will migrate domestically by 2050 because of climate change—the largest number predicted in any of six major regions the organization studied for a new report.

    At the height of the most recent drought, which lasted from 2018 to 2020, only about half as much rain fell in Zimbabwe as usual. Crops were scorched and pastures dried up. People and livestock crowded around hand-pumped boreholes to find water, but the wells soon went dry. Some people in the driest areas had so little to eat they survived on the leaves and white, powdery fruit of baobab trees.

    More rain fell during the last growing season, but many farmers still feel uneasy about the future. Maize—Zimbabwe’s staple crop, which was aggressively promoted by the former colonial government beginning in the 1940s—is becoming impossible to grow.

    ...

    Over 5 million Zimbabweans—a third of the population—don’t have enough to eat, according to the World Food Program. A study in 2019 of how vulnerable countries were to agricultural disruption due to drought ranked Zimbabwe third, behind only Botswana and Namibia.

    ...

    As Mutero and other climate migrants know, conditions are somewhat better in the Eastern Highlands. This mountainous region stretches for around 300 kilometers along Zimbabwe’s border with Mozambique. Many of the region’s major rivers, including the Pungwe and Odzi, begin there as streams. The area’s climate and fertile soils are perfect for growing crops such as tea, coffee, plums, avocados, and a sweet pinkish-red fruit called lychee.

    When climate migrants started showing up in the Eastern Highlands a decade ago, they settled without permission on state land, and the government was swift to evict them. But they returned in even larger numbers, and officials have more or less given up trying to stop them.

    By 2015, the government estimated that more than 20,000 migrants had settled in the Eastern Highlands. Though no more recent official estimates exist, anecdotal evidence suggests the number has continued to climb.

    Today in some parts of the highlands, migrants occupy any vacant land they can find. In others, traditional or community leaders like the one helping Mutero, who are known in local dialect as sabhuku, have taken up the task of allocating land to migrants. The leaders—whose roles are largely ceremonial—are doing this in defiance of government orders. They’ve earned praise from migrants but disdain from local farmers who were there first.

    ...

    Leonard Madanhire, a farmer who lives in what’s known as the Mpudzi area in the Eastern Highlands, is worried. He grows mostly maize on his five hectares of land. His herd of cattle has dwindled from more than 20 a decade ago to five. Most nearby grazing lands, which he has long shared with other farmers, are now occupied by climate migrants.

    In September, Madanhire took me on a long hike along the banks of the Chitora River. Freshly built dwellings stood on land that was once pasture; other structures dotted the river’s banks. A couple of seemingly frustrated herdsmen were trying to steer cattle and goats through the narrow patches of pasture that remained.

    A few kilometers upriver, migrants had planted vegetable gardens on the river’s edges. Madanhire says farming along the banks that way causes erosion and puts more silt and debris in the water for everyone downstream.

    ...

    “As climate change intensifies, it is going to make some of these areas uninhabitable,” she says. “Rather than having to deal with a rushed mass migration, which will put severe pressure on the areas that people migrate to, we should be planning for a gradual evacuation of the most vulnerable areas now.”

    She says the government should do a nationwide land audit to figure out where space is available for migrants and create a process by which people can legally resettle there—perhaps with a bit of money or other support to get them started. While the government is doing a lot to properly relocate people from flood-prone areas, it’s doing little to relocate farmers from places prone to drought

    Texas' Gulf Coast Communities Are Fighting Against Big Oil and Gas
    https://www.texasobserver.org/the-export-boom/

    In the next few years, the city is poised to become one of the nation’s largest liquified natural gas (LNG) export hubs, piping in natural gas from the Permian Basin in West Texas, chilling it to subzero temperatures, and loading the gas, now in liquid state, onto tankers headed for Europe and Asia, where it will be burned in power plants. Exxon Mobil’s Golden Pass facility is under construction, and Sempra Energy is planning to move forward with its facility just up the river. When they’re both up and running, the plants will have a combined export capacity of nearly 30 million tons of LNG per year.

    Port Arthur isn’t alone. All along the nearly 400-mile stretch of Texas’ Gulf Coast, nearly a dozen oil and gas export terminals are slated to come online within the next decade. The Gulf Coast as a whole has long been a major energy hub, with nearly half of the nation’s existing oil and gas refining capacity already here. For decades, the facilities built here were import-oriented: The United States was consuming far more energy than the nation could produce. That began to change in 2008, when a revolution in fracking freed up millions of barrels of oil and gas trapped in shale formations in Texas, Pennsylvania, and North Dakota. Then, in 2015, Congress repealed a decades-old ban on crude oil exports, opening the floodgates of American oil and gas to the rest of the world.

    In towns like Port Arthur, coastal residents are fighting against the new wave of oil and gas export plants: challenging permits, staging protests at home or joining forces with activists abroad, and calling for an outright ban on all fossil fuel exports. Farther down the coast, communities are rallying to stop industry from entering their area altogether. In Brownsville, local opposition to two LNG export plants started when the proposals were first submitted for review seven years ago.

    By 2024, Texas’ LNG production capacity is on track to quadruple, from 30 million tons a year to nearly 120 million tons per year. Almost all of the United States’ oil exports already leave from the Gulf Coast, where pipelines and refineries crisscross the landscape.

    ...

    But the terminals will irrevocably change the coast’s ecology. Acres of sensitive wetlands, marshes, and prairies that provide safe shelter for millions of migratory birds and sea turtles will be disrupted or destroyed. Naturally shallow bays and inlets will be dredged to make room for some of the largest shipping containers in the world, burying oyster reefs and fisheries. The communities who live closest to the plants will breathe dirtier air as the plants emit thousands of pounds of toxic chemicals like benzene, volatile organic compounds, and carbon monoxide. When the exported oil or gas is burned for power halfway around the world, it will release vast amounts of greenhouse gases, which fuel climate change. The already vulnerable Texas coast will be even more prone to deadly heat waves, strong storms, and long droughts.

    “Communities on the Gulf Coast are already hit hard by climate disasters,” says Ethan Buckner, an organizer with the environmental watchdog group Earthworks. “They are impacted by the acute increase of emissions and pollution, and now they are being asked to take on the burden of new pipelines, storage terminals, processing plants, and dredging projects—it’s sacrificing the communities and the climate.”

    The movie Don’t Look Up is satire. But speaking as a climate scientist doing everything I can to wake people up and avoid planetary destruction, it’s also the most accurate film about society’s terrifying non-response to climate breakdown I’ve seen.
    The film, from director Adam McKay and writer David Sirota, tells the story of astronomy grad student Kate Dibiasky (Jennifer Lawrence) and her PhD adviser, Dr Randall Mindy (Leonardo DiCaprio), who discover a comet – a “planet killer” – that will impact the Earth in just over six months. The certainty of impact is 99.7%, as certain as just about anything in science.
    The scientists are essentially alone with this knowledge, ignored and gaslighted by society. The panic and desperation they feel mirror the panic and desperation that many climate scientists feel. In one scene, Mindy hyperventilates in a bathroom; in another, Dibiasky, on national TV, screams “Are we not being clear? We’re all 100% for sure gonna fucking die!” I can relate. This is what it feels like to be a climate scientist today.

    Fungi Are Capturing More Carbon Than We Thought | Discover Magazine
    https://www.discovermagazine.com/environment/fungi-are-capturing-more-carbon-than-we-thought

    Scientists had long thought it simply evaporated into the atmosphere. But that didn’t sit right with Davinia Salvachúa Rodríguez, a microbiologist at the National Renewable Energy Laboratory in Golden, Colorado. After 10 years of studying white-rot fungi, she demonstrated that it eats the carbon in lignin to fuel its growth, according to a March study in Proceedings of the National Academy of Sciences (PNAS). Rodríguez’s discovery flags white-rot fungi as a key player in sequestering lignin-derived carbon in soil.

    Similarly, Stanford University microbiologist Anne Dekas published a study in June in PNAS showing that parasitic fungi that live on tiny algae in oceans and lakes remove some of the carbon inside the algae, which might otherwise reenter the atmosphere.

    Conventional wisdom had maintained that all of the carbon inside the algae remained in a microbial feedback loop near the water’s surface, where microbes consumed the green plants and then released the C02. But Dekas and colleagues showed instead that the fungi siphon off up to 20 percent of the algae’s carbon. Then — because the fungi outsize the microbes in the feedback loop — the fungi become a more likely meal for larger species, which remove them from the loop. As the carbon makes its way up the food chain, it may eventually sink to the ocean floor, which also sequesters carbon, when the top species dies.

    A final decision has yet to be taken about where to store tens of thousands of tonnes of nuclear waste produced in German power plants. Experts say some material will remain dangerously radioactive for 35,000 generations.
