    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.

    Chile Writes Its Constitution, Confronting Climate Change Head On
    https://www.nytimes.com/2021/12/28/climate/chile-constitution-climate-change.html

    After months of protests over social and environmental grievances, 155 Chileans have been elected to write a new constitution amid what they have declared a “climate and ecological emergency.”

    Their work will not only shape how this country of 19 million is governed. It will also determine the future of a soft, lustrous metal, lithium, lurking in the salt waters beneath this vast ethereal desert beside the Andes Mountains.

    ...

    Mining companies in Chile, the world’s second-largest lithium producer after Australia, are keen to increase production, as are politicians who see mining as crucial to national prosperity. They face mounting opposition, though, from Chileans who argue that the country’s very economic model, based on extraction of natural resources, has exacted too high an environmental cost and failed to spread the benefits to all citizens, including its Indigenous people

    And so, it falls to the Constitutional Convention to decide what kind of country Chile wants to be. Convention members will decide many things, including: How should mining be regulated, and what voice should local communities have over mining? Should Chile retain a presidential system? Should nature have rights? How about future generations?

    ...

    Anger boiled over into huge protests starting in 2019. A national referendum followed, electing a diverse panel to rewrite the constitution.

    On Dec. 19 came another turning point. Voters elected Gabriel Boric, a 35-year-old former student activist, as president. He had campaigned to expand the social safety net, increase mining royalties and taxes, and create a national lithium company.

    The morning after his victory, the stock price of the country’s biggest lithium producer, Sociedad Química y Minera de Chile, or SQM, fell 15 percent.

    ...

    Joaquin Villarino, president of the Mining Council, the industry lobby, said both could diminish Chile’s appeal to investors. He voiced particular worry that some of the Convention members appeared to be against mining altogether, though he didn’t name any. “I hope this is not what we will have in our Constitution,” he said, “because Chile is a mining country.”

    The Convention is also likely to make water a public good. But another question will bear on the industry even more: Is brine — the saltwater beneath the desert — technically water? Mining companies assert it is not, because it is fit for neither human nor animal consumption.

    ...

    Dr. Dorador is vying to be the convention’s president. She wants the constitution to recognize that “humans are part of nature.” She bristles when asked if lithium extraction is necessary to pivot away from fossil fuel extraction. Of course the world should stop burning oil and gas, she says, but not by ignoring yet unknown ecological costs. “Someone buys an electric car and feels very good because they’re saving the planet,” she says. “At the same time an entire ecosystem is damaged. It’s a big paradox.”

    Indeed the questions facing this Convention aren’t Chile’s alone. The world faces the same reckoning as it confronts climate change and biodiversity loss, amid widening social inequities: Does the search for climate fixes require re-examining humanity’s relationship to nature itself?

    ...

    “We have to face some very complex 21st century problems,” said Maisa Rojas, a climate scientist at the University of Chile. “Our institutions are, in many respects, not ready.”

    Climate change: Hurricanes to expand into more populated regions
    https://news.yahoo.com/climate-change-hurricanes-expand-more-174206391.html

    Poleward expansion of tropical cyclone latitudes in warming climates | Nature Geoscience
    https://www.nature.com/articles/s41561-021-00859-1

    Climate change will expand the range of tropical cyclones, making millions more people vulnerable to these devastating storms, a new study says.

    At present, these cyclones - or hurricanes as they are also known - are mainly confined to the tropical regions north and south of the equator.

    But researchers say that rising temperatures will allow these weather events to form in the mid-latitudes.

    The scientists involved say their work shows by the end of this century, cyclones will likely occur over a wider range than they have for three million years

    Doomsday Glacier in Antarctica Could Collapse Soon: New Research - Rolling Stone
    https://www.rollingstone.com/politics/politics-features/doomsday-glacier-thwaites-antarctica-climate-crisis-1273841/

    the West Antarctic ice sheet is one of the most important tipping points in the Earth’s climate system. If Thwaites Glacier collapses, it opens the door for the rest of the West Antarctic ice sheet to slide into the sea. Globally, 250 million people live within three feet of high tide lines. Ten feet of sea level rise would be a world-bending catastrophe. It’s not only goodbye Miami, but goodbye to virtually every low-lying coastal city in the world.

    ...

    Depending on various emissions scenarios in the latest Intergovernmental Panel on Climate Change report, we could have as little as one foot of sea level rise by the end of the century, or nearly six feet of sea level rise (of course, rising seas won’t stop in 2100, but that date has become a common benchmark). “The difference between those [models] is a lot of lives and money,” says Richard Alley, a glaciologist at Penn State University and one of the great ice scientists of our time. Alley adds: “The most likely place to generate [the worst scenario] is Thwaites.”

    Or to put it more urgently: “If there is going to be a climate catastrophe,” Ohio State glaciologist Ian Howat once told me, “it’s probably going to start at Thwaites.”

    ...

    “We just don’t know what the upper boundary is for how fast this can happen,” Alley says. “We are dealing with an event that no human has ever witnessed before. We have no analog for this.”

    ...

    “The current divergence among model predictions is actually a good sign because it means that scientists are probing different parameterizations, representations of processes, and hypotheses,” writes Jeremy Bassis, a geophysicist at the University of Michigan. Bassis suggests not focusing so much on the long-term uncertainty and highlighting instead what scientists know about the next few decades. “The skill of models in predicting sea level change on decadal time scales is high, and we already have actionable projections on these time scales. We should be emphasizing that fact in discussions with community members, stakeholders, and decision-makers, so they can move ahead with important adaptation and mitigation planning.”

    But in the long run, it is not clear that the dynamics of ice sheet collapse that are underway at Thwaites can be stopped. As glaciologist Eric Rignot put it in 2015, in Antarctica, “the fuse has been blown.” Even if we cut carbon emissions to zero tomorrow, warm water will continue to flow beneath the ice sheet for decades, destabilizing the ice and further pushing the glacier toward eventual collapse. This doesn’t means that cutting carbon pollution to zero isn’t an important goal — nothing, in fact, is more important or more urgent. “We may have a small safety margin in Antarctica, but not a large one,” says Alley. Even if the fuse is blown, cutting emissions fast could slow it all down to a millennium-long crack-up that will give us more time to adapt. One way or another, our future is written in ice.
