    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.

    PER2: cool

    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.

    A Synthesis of Ranch-Level Sustainability Indicators for Land Managers and to Communicate Across the US Beef Supply Chain - ScienceDirect
    https://www.sciencedirect.com/science/article/pii/S1550742421001020

    Our objective was to synthesize existing guidance on monitoring and assessing ranch-scale sustainability in the United States and to identify core ecological, social, and economic indicators that could identify well-managed ranching, support adaptive management, and demonstrate producers’ sustainability and continuous improvement to retailers and consumers. We evaluated 21 range and pastureland assessments from nongovernmental organizations, agencies, and academics that totaled 180 indicators. From this, we selected 20 commonly used “core” indicators (12 ecological and 8 socioeconomic). We identified indicators that are designed to detect change over time for management practices, common among many approaches, and/or critical indicators for outcomes of common interest to producers, companies, and consumers. The synthesis of indicators across many guidance documents offers insight into what a diverse set of range professionals and institutions see as critical to demonstrate and track ranch-level sustainability, and producers, consumers, and companies may find a subset of these indicators to be relevant for their operation and region, values, and/or company sustainability goals.

    The West’s Unprecedented Water Crisis Is Worsening - The Atlantic
    https://www.theatlantic.com/ideas/archive/2021/12/kansas-aquifer-ogallala-water-crisis-drought/621007/

    It is no secret that one of the worst droughts in 1,000 years is intensifying heat waves and megafires; that historic drops in surface-water levels coincide with historic spikes in demand as the region grows hotter, drier, and more populated; or that conflicts are escalating over who gets to use how much of what remains. Acute scarcity drives the search for water underground. But the West’s major aquifers are in trouble, too.

    Aquifers are essential resources for human survival. Groundwater provides the only source of drinking water for one-third of the world’s people and supports nearly half of the planet’s irrigated agriculture. Yet far more groundwater is being pumped out than can be naturally replenished. Most dry-area aquifers are vanishing. These include the two primary groundwater systems in the western United States: California’s Central Valley aquifer and the Ogallala Aquifer, which underlies America’s heartlands from South Dakota to Texas. If we lose these aquifers, we lose nearly 20 percent of the world’s grain crop, more than 40 percent of our nation’s beef production, and about 40 percent of the vegetables, nuts, and fruits consumed in the United States.

    ...

    Some consequences of aquifer loss are already visible in western Kansas, where I grew up and where my family has farmed for generations. Eight decades of intensive pumping caused the water table to plummet. Nearly all springs and streams have gone dry. Most wells have dwindled, and many have been emptied altogether. Now the same place that nurtured generations of my family has one of the world’s highest rates of aquifer decline.

    Today, the same deep-well irrigation that gave farmers like my great-grandfather a second chance after the Dust Bowl, in the 1930s, is exhausting the portion of the aquifer that remains. This poses a threat to the existence of many Plains communities, which have already been hit hard by the corporate takeover of farmland, declining populations, rising deaths from suicide and substance abuse, and racial and economic inequities. The profits of industrial agriculture flow from groundwater; so do our communities’ tax bases, land values, and budgets for hospitals, schools, and social services.

    ...

    As Earth warms and droughts intensify, these pressures will only increase.

    When groundwater runs out, myths of growth and profit collapse into dust. Drying aquifers can result in starvation, migration, and violence. Or they can prompt us to rethink our relationship to one another and to the irreplaceable natural resources that we share. Aquifers belong to everyone, and especially to future generations.

    Boulder, Colorado and surrounding towns

    A series of grass fires have evolved into a major situation in Colorado. The fire, called the Marshall Fire, is located just south of Boulder city limits. Fires started between 1100 and 1300 local time after wind gusts of over 105 miles per hour were recorded, bringing down power lines in the area. Wind gusts continue to fuel the fire, which has caused aerial tankers not to be able to assist ground units in firefighting operations. The towns of Superior (12,000 people) and Louisville (18,000 people) are under mandatory evacuation orders as fires threaten the two towns.
