    "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.

    Surging Methane Emissions Could Be a Sign of a Major Climate Shift - Inside Climate News
    https://insideclimatenews.org/news/28082024/surging-methane-emissions-major-climate-shift/

    A 2021 pledge by more than 100 nations to cut methane emissions from anthropogenic sources 30 percent by 2030 might not slow global warming as much as projected, as new research shows that feedbacks in the climate system are boosting methane emissions from natural sources, especially tropical wetlands.

    A new trouble spot is in the Arctic, where scientists recently found unexpectedly large methane emissions in winter. And globally, the increase in water vapor caused by global warming is slowing the rate at which methane breaks down in the atmosphere. If those feedbacks intensify, scientists said, it could outpace efforts to cut methane from fossil fuel and other human sources.

    What Trump 2.0 Could Mean for the Environment
    https://www.nytimes.com/2024/07/16/climate/trump-epa-regulation.html

    “President Trump made America a net exporter of energy for the first time because he cut red tape and gave the industry more freedom to do what they do best — utilize the liquid gold under our feet.” If elected, he would “cancel Joe Biden’s radical mandates, terminate the Green New Scam, and make America energy independent again,” she said.

    ...

    At various points, courts overturned the Trump administration’s attempts to relax restrictions on carbon-dioxide emissions from power plants; blocked a rule that would have limited what scientific studies the E.P.A. could use; and found the administration broke the law when it failed to enact nationwide standards to curb harmful ozone pollution. Judges also rejected attempts to take gray wolves off the endangered species list and to roll back rules that restricted methane leaks from oil and gas wells.

    ...

    The courts could also prove more sympathetic next time around. With three Supreme Court justices appointed by Mr. Trump, the court now has a conservative supermajority that has shown a deep skepticism toward environmental regulation. The court has sometimes blocked rules that were still being adjudicated in lower courts or before they were implemented.

    In June, the Supreme Court overturned the so-called Chevron doctrine, which for 40 years said that courts should defer to government agencies when a law is unclear. That ruling could undercut the regulatory authority of many federal agencies. The Supreme Court also halted E.P.A. rules that limited smokestack pollution blowing across state borders, overturned expanded protections for millions of acres of wetlands and narrowed the agency’s ability to regulate emissions from power plants.

    ...

    many environmentalists say that while they might block some moves, they can’t force a Trump administration to adopt policies that will cut greenhouse gases. And the window to limit global warming to relatively low levels is rapidly closing.

    “There’s no skeleton key that’s going to protect everything Biden has accomplished,” said Sam Ricketts, founder of S2 Strategies, a clean-energy consulting group. “I’d love to say that there is a fail-safe plan to protect the gains we’ve made should Trump be president again. There is not.”

    Rising methane could be a sign that Earth's climate is part-way through a 'termination-level transition'
    https://theconversation.com/rising-methane-could-be-a-sign-that-earths-climate-is-part-way-through-a-termination-level-transition-211211

    In the past few million years, Earth’s climate has flipped repeatedly between long, cold glacial periods, with ice sheets covering northern Europe and Canada, and shorter warm inter-glacials.

    When each ice age ended, Earth’s surface warmed by as much as several degrees centigrade over a few millennia. Recorded in air bubbles in ice cores, sharply rising methane concentrations are the bellwethers of these great climate-warming events. With each flip from a glacial to an interglacial climate there have been sudden, sharp rises in atmospheric methane, likely from expanding tropical wetlands.

    These great climate flips that ended each ice age are known as terminations. Each has a Roman numeral, ranging from Termination IX which happened about 800,000 years ago to Termination IA which initiated the modern climate less than 12,000 years ago. For example, around 131,000 years ago during Termination II, the British climate suddenly flipped from glaciers in the Cotswolds to hippopotami wallowing in what is now Trafalgar Square.

    Full terminations take several thousands of years to complete, but many include a creeping onset of warming, then a very abrupt phase of extremely rapid climate change that can take a century or less, followed by a longer, slower period during which the great ice caps finally melt. In the abrupt phase of the great change that brought about the modern climate, Greenland’s temperature rose by around 10°C within a few decades. During these abrupt phases, methane climbs very steeply indeed.

    ...

    Methane fluctuated widely in pre-industrial times. But its increasingly rapid growth since 2006 is comparable with records of methane from the early years of abrupt phases of past termination events, like the one that warmed Greenland so dramatically less than 12,000 years ago.

    There is already lots of evidence that the climate is shifting. Atlantic ocean currents are slowing, tropical weather regions are expanding, the far north and south are warming fast, ocean heat is breaking records and extreme weather is becoming routine.

    In glacial terminations, the entire climate system reorganises. In the past, this took Earth out of stable ice age climates and into warm inter-glacials. But we are already in a warm interglacial. What comes next is hard to imagine: loss of sea ice in the Arctic in summer, thinning or partial collapse of the ice caps in Greenland and West Antarctica, reorganisation of the Atlantic’s ocean currents and the poleward expansion of tropical weather circulation patterns. The consequences, both for the biosphere in general and food production in south and east Asia and parts of Africa in particular, would be very significant

    An expensive global climate experiment | DW Documentary
    https://youtu.be/MtsQPV49cAk


    Peatlands are very often the setting for chilling folklore. But they serve an important function - for the climate and biodiversity. They’re capable of absorbing and storing large amounts of carbon dioxide, thereby helping to mitigate the climate crisis. Nevertheless, bogs are still being destroyed all over the world.

    In Finland, peatlands are being drained to extract peat and generate energy. With dramatic consequences: less than half of all the country’s bogs are still intact. Tero Mustonen is a climatologist. He founded the organization Snowchange, to protect and save peatlands. Together with members of his village, Snowchange sued the energy company responsible for the destruction of the Linnunsuo wetland. Mustonen’s organization is now engaged in the worldwide fight to salvage and rewild biotopes.

    Greta Gaudig and Sabine Wichmann also campaign for the revitalization of peatlands. At the Greifswald Moor Center, the two conduct research on what’s known as paludicultures: plant species that can be farmed in wetlands. Gaudig and Wichmann want to recreate moorlands previously drained for agriculture. "We need to convince farmers," the agronomist Sabine Wichmann explains. After all, ultimately they are the ones who will need to invest if they are to continue living off their land.

    One of the world’s most expensive and far-reaching climate experiments is taking place in the US state of Minnesota: in the Marcell Experimental Forest. Here, co-founder Randy Kolka is working with scientists from all over the world. Together they’re studying the connection between peatlands and climate change. Their findings are included in reports by the Intergovernmental Panel on Climate Change, thereby impacting political decision-making.

    Global Warming in the Pipeline
    https://youtu.be/v-ArA_xYxfs


    Dr. Peter Carter, Paul Beckwith and Regina Valdez discuss a recent paper called ‘Global Warming in the Pipeline’ by James Hansen et al. The paper explains global warming will likely pierce the 1.5°C ceiling in the 2020s and 2°C before 2050 under the current geopolitical approach to dealing with anthropogenic greenhouse gas emissions.

    This video was recorded on May 24th, 2023, and published on June 18th, 2023.

    Some of the topics discussed:
    - How one of the key characteristics of climate change known for decades has always been inertia and momentum. This paper shows that at the current levels of greenhouse gases in the atmosphere, the planet is slowly moving towards a 10°C rise in global average temperature.
    - How James Hansen is a voice crying in the climate wilderness as he always seems to have been because the scientific community is not agreeing with him.
    - How one of the big feedbacks in the climate system is ice sheet albedo and its key role in leading us to a 10°C rise.
    - How the methane emissions feedback from the warming of the wetlands will be inevitable.
    - How a new draft of the paper was released on May 19th.
    - How the Global Climate Models (GCMs) have been under predicting the global average temperature rates of change and how by using the Equilibrium Climate Sensitivity (ECS), which is how much the climate warms for a doubling of CO2 levels, we can arrive at much more accurate prediction of global average temperature rise from paleoclimate data.
    - The enormity of consequences of climate change demands a return to a Holocene-level global temperature with the required actions that include: 1) A global increasing price on GHG emissions; 2) An East-West cooperation in a way that accommodates developing world needs; 3) Intervention with Earth’s radiation imbalance to phase down today’s massive human-made “geo-transformation” of Earth’s climate.
    - and much more. . .

    Water has to become a common good – two new reports show — Potsdam Institute for Climate Impact Research
    https://www.pik-potsdam.de/en/news/latest-news/water-has-to-become-a-common-good-2013-two-new-reports-show

    „We are now pushing the global water cycle out of balance, undermining the source of all freshwater – precipitation – upon which societies are completely dependent on,” Johan Rockström explains.

    The 32-pages GCEW report titled Turning the Tide: A Call to Collective Action, marks the first time the global water system has been scrutinized comprehensively as well as its value to countries — and the risks to their prosperity if water is neglected.

    The majority of countries depend on the evaporation of water from neighboring countries for about half of their water supply. This "green" water is held in soils and transpired from forests and other ecosystems. Countries are not only interconnected by transboundary blue water flows but also through green water, i.e., atmospheric green water flows of water vapor, flows which extend far beyond traditional watershed boundaries.

    Water is not just a casualty but also a driver of the climate crisis. Extreme water events cause an immediate loss of carbon uptake in nature. Droughts lead to fires and massive loss of biomass, carbon, and biodiversity. The loss of wetlands is depleting the planet's greatest carbon store, while the drop in soil moisture is reducing the terrestrial and forest ecosystem's ability to sequester carbon.

    Extensive global wetland loss over the past three centuries | Nature
    https://www.nature.com/articles/s41586-022-05572-6

    Wetlands have long been drained for human use, thereby strongly affecting greenhouse gas fluxes, flood control, nutrient cycling and biodiversity1,2. Nevertheless, the global extent of natural wetland loss remains remarkably uncertain3. Here, we reconstruct the spatial distribution and timing of wetland loss through conversion to seven human land uses between 1700 and 2020

    ...


    We estimate that 3.4 million km2 (confidence interval 2.9–3.8) of inland wetlands have been lost since 1700, primarily for conversion to croplands. This net loss of 21% (confidence interval 16–23%) of global wetland area is lower than that suggested previously by extrapolations of data disproportionately from high-loss regions. Wetland loss has been concentrated in Europe, the United States and China, and rapidly expanded during the mid-twentieth century

    Great illustration. Note, #wetlands have the highest #carbon storage per area (hectare or acre), no doubt, but #grasslands have vastly more area and are, in total, the largest terrestrial carbon store. We must never drain existing existing wetlands for anything, and certainly not for grazing, yet, ironically, when we graze properly along river banks and natural depressions, we can expand and recreate wetlands. This is exactly what many HM ranchers are doing, recreating wetlands. Yebo that.

    monbiot proti regenerativni pastve

    Perhaps the most important of all environmental issues is land use. Every hectare of land we use for extractive industries is a hectare that can’t support wild forests, savannahs, wetlands, natural grasslands and other crucial ecosystems. And farming swallows far more land than any other human activity.

    What are the world’s most damaging farm products? You might be amazed by the answer: organic, pasture-fed beef and lamb. I realise this is a shocking claim. Of all the statements in my new book, Regenesis, it has triggered the greatest rage. But I’m not trying to wind people up. I’m trying to represent the facts. Let me explain

    The truth about methane is that there is no stopping its accelerating growth.

    We can mitigate anthropogenic methane, but we can't do anything about wetlands, Siberia, ESAS clathrates and the latest, news about declining hydroxyl, the primary sink of methane, due to wildfires.

    Just to be clear, "accelerating growth" means a positive second derivative, which is evidenced by the recent "concave up" shape to the NOAA graph.

    Accelerating growth is emphatically NOT the same as exponential growth, which requires every derivative to be positive.

    The agenda methane has is one that is clear and to the point: methane is the ultimate vaccine for the planet, doing its job to heal the ecosystem from the virus that is humanity.

    Water is a stream of geopolitical force through history | Aeon Essays
    https://aeon.co/essays/water-is-a-stream-of-geopolitical-force-through-history

    A great river encircles the world. It rises in the heartland of the United States and carries more water than the Mississippi and Yangtze rivers combined. One branch, its oldest, streams over the Atlantic, heading for Europe and the Middle East. Another crosses the Pacific, flowing towards China. Countless tributaries join along the way, draining the plains and forests of Latin America, Europe and Asia.

    You probably have never heard of such a river, even though almost all of us draw from it. You cannot fish in it, float on it, drink from it. If you were to look, you would not find it: it is invisible. Yet there is no doubt that it flows.

    The river starts anywhere water feeds agriculture. But from there, physical water vanishes, replaced by a flow of crops that carry only the memory of the water used to produce them. Crops then travel along the shipping lanes of the global trade system, eventually displacing the water that would have otherwise been used to grow them locally. Thus, water flows from source to destination ‘embedded’ in its products. It is a flow of ‘virtual water’, an idea first developed in the 1980s by the late geographer Tony Allan.

    This great virtual river helps explain how nations exercise power over each other. It is far from a coincidence that its dominant source today is the waters of the Mississippi. Its current path was established when Franklin Roosevelt’s US replaced Britain as the world’s hegemon. The US began feeding an imploding, war-torn Europe with crops nourished by the rich waters of Old Man River, and the rest is history.

    ...

    All through the 20th century, trading the products of a country’s water resources was an act of power. When the US became the granary of the world, flooding food eastward, it also provoked a countercurrent of hard currency streaming back to pay for it, setting the stage for the Bretton Woods settlement.

    Lenin and Stalin paid for Soviet industrialisation with cereal production of Ukrainian, Russian and Central Asian fields, irrigated by canals built by thousands of Gulag prisoners. In China, Mao may well have measured the targets of the Great Leap Forward in tons of steel, but planned to fund their pursuit by irrigating the plains of the Yangtze and Yellow rivers.

    Ibn Saud knew that oil might make him wealthy, but only water to irrigate Saudi Arabia would give him power, so the former paid for the latter. And the 1970s postcolonial competition for regional influence over water reached a peak when the pan-Arabism of Egypt’s president Gamal Abdel Nasser collided with Israel’s claims over the Jordan River, seeding conflicts that – from the Arab Spring to the Syrian crisis – have contributed to shaping the contemporary world.

    Yet the geopolitical value of water ended up hidden from view. A thick layer of 20th-century industrialisation concealed the force of water behind countless dams and vast embankments, replumbing the planet and fooling people into believing that modernity had emancipated their life from concerns about water.

    ...



    The drying of the Colorado River, the decimation of the forests of the Amazon and Congo basins, the flood-ridden plains of the Rhine and Yellow rivers, the disappearing wetlands of the Murray-Darling River are all evidence that a vast agricultural trade system continues to transform the face of the planet. And water continues to be its blueprint.

    You cannot see the great virtual river, even if it continues to grow. But, unseen, it still matters. It shapes the environment we all live in. It creates powerful dependencies between nations. Above all, it is an expression of power. You might not be able to see it, but its shadow stretches behind you in time.

    Rising methane: is there a methane emergency?
    https://royalsocietypublishing.org/doi/full/10.1098/rsta.2021.0334

    The atmospheric methane burden rose rapidly in 2020: more rapidly than at any previous time in the observational record. The causes of this rise are complex and not well understood. It is likely much of the growth is driven by increased emissions from biological sources, such as natural wetlands, agriculture and landfills, especially in the Tropics and sub-Tropics. Other processes such as declining methane sinks may also be contributing.

    The methane budget is not closed. In the overall estimates by Saunois et al. (2020), there are wide uncertainty margins in each sub-category and huge discrepancies between Top-Down and Bottom-Up assessments. Moreover, in seeking to track methane, we are chasing a very fast-changing target—the global methane budget in 2021 is very different from the budget in 2010.

    ...

    Is the warming feeding the warming? Will methane emissions rise in response to climate warming? The answer is not known: it depends on what exactly is driving growth. A warmer world is also a wetter world. Wetland emissions grow both with temperature and with wetland area. Thus, a feedback is likely and expected. Tropical and Boreal/Arctic wetland sources will most probably emit more methane.

    As the planet warms, becoming wetter and hotter, and the Tropics expand, tropical farming will become more productive. An increase in human agriculture will likely occur with more ruminants, more crops and crop waste fires, more use of fertilizer running off into wetlands, all leading to methane emission.

    Fossil fuel methane emissions may also respond to climate warming. Although warmer winters in the North may lead to a decline in the use of gas for heating, warmer Tropical and sub-Tropical summers will occur. Air conditioning is now very widespread across the tropics and sub-tropics and will drive rising demand for electricity, much of it currently gas- or coal-fired with attendant methane emissions

    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.”

    While the report includes some positive trends — like record increases in the use of solar and wind energy, and institutions divesting money from the fossil fuel industry — it paints a generally bleak picture of the future, accentuated by ongoing surges in climate-related disasters like floods, hurricanes, wildfires and heat waves, the authors wrote. The planet may also be about to pass (or has already passed) critical natural tipping points — such as the Amazon rainforest becoming a carbon source rather than a carbon sink — from which it will be hard to recover, the team added.

    ...

    To accomplish this task, the team suggests a three-pronged near-term policy approach: 1) Implement a "significant" global carbon price to reduce emissions; 2) phase out and eventually ban fossil fuels; and 3) restore and protect key carbon-rich ecosystems, like forests and wetlands, to preserve the planet's largest carbon sinks and protect biodiversity.

    #methane #doomed

    We would have expected elevated methane in areas with wetlands,” Froitzheim says. “But these were not over wetlands but on limestone outcrops. There is very little soil in these. It was really a surprising signal from hard rock, not wetlands.” The carbonates in the outcroppings date back 541 million years to the Paleozoic era, according to the US Geological Survey.
    ...
    The biggest sources of methane in the world are agricultural, such as rice growing, and leaks and flares from oil and gas operations, such as in the US Permian Basin in Texas and New Mexico where production has soared in the past decade.
    ...
    The study said that gas hydrates in the Earth’s permafrost are estimated to contain 20 gigatons of carbon. That’s a small percentage of all carbon trapped in the permafrost, but the continued warming of gas hydrates could cause disruptive and rapid releases of methane from rock outcrops.
