 A sky with a feverThe thermostat never negotiated. The insurers read it first. Phoenix has now strung together a hundred consecutive days above one hundred degrees. Maricopa County counted hundreds of heat deaths in the summer that began the run, most of them indoors, most of them poor, most of them invisible to anybody with air conditioning and a car. James Hansen told a Senate committee in June 1988 that the greenhouse effect had been detected and was already changing the weather. The hearing was staged to be uncomfortable, windows open and the room hot, and the performance was covered widely and then forgotten. Hansen had been publishing on the subject since the early 1980s and his numbers have held up uncomfortably well against three decades of measurement. The physics is unremarkable and was understood in the nineteenth century: add carbon dioxide to an atmosphere and it traps outgoing heat. What took time was accounting for consequences, and that is where the warnings stacked up — a warming curve, a sea-level curve, then a list of tipping elements including ice sheets, permafrost, ocean circulation and tropical forests, each with a threshold beyond which change becomes self-sustaining. Johan Rockström and a network of Earth-system scientists mapped those boundaries and found the planet already outside several of them. Measurement has since caught up with theory in the most literal way available. The warmest years ever instrumented now fall in the middle of this decade, and one of them became the first calendar year in which the global average sat more than one and a half degrees above the pre-industrial baseline. Reefs suffered the largest bleaching event on record, and ocean heat content set new highs, which matters because the sea absorbs most of the excess energy and then hands it back through storms. At national scale the events have names. A hurricane stalled over the Carolinas and drowned a mountain town considered a climate refuge.* A wind-driven firestorm erased a Hawaiian town in an afternoon. In 2025 alone the country absorbed a hill-country flash flood that killed more than a hundred people overnight and a January firestorm that consumed thousands of structures in Los Angeles. The federal disaster tally passed two dozen billion-dollar events in a single year, a count that used to be anomalous and is now baseline. Heat is the quieter killer and it registers in mortality statistics few people read. Farmworkers, roofers, delivery drivers and the elderly die in numbers that surface only in county reports. Occupational regulators drafted a heat rule and are still arguing about it while the thermometer does the persuading. Meanwhile the megadrought that has gripped the Southwest since the turn of the century, the driest stretch in more than a thousand years by tree-ring reconstruction, has begun to be described not as a drought but as the climate. Money is where the warning stops being environmental and becomes financial, because insurers are the fastest readers of a changing atmosphere — they price the future annually. Two of California’s largest carriers stopped writing new homeowner policies after a run of fire seasons, then negotiated a return with concessions on how risk may be modelled. In Florida, a string of undercapitalised insurers went insolvent and the state-backed carrier became the largest in the market, which is another way of saying the public is now the insurer of last resort. Federal flood cover, underpriced for decades, was repriced through a risk-based system that revealed how many homes were quietly subsidised by everyone else. When a house becomes impossible to insure, getting a mortgage becomes harder, and selling it can be just as difficult. Municipal bond markets have started to notice which towns depend on a tax base sitting in a floodplain.   Animas River in flood three days later A river divided by men who saw a floodA compact written in a wet decade, and a grid built for a smaller country. In 1922 seven men sat down to divide a river using the wettest decade in a thousand years of record. The Colorado River Compact allocated roughly sixteen and a half million acre-feet annually among the basin states and, later, Mexico, a figure the river has failed to meet in most years since. The signatories were not careless; they were measuring a flood and calling it a norm. A century later the reservoir behind Hoover Dam fell to its lowest level since the 1930s, and the one behind Glen Canyon dropped by roughly two-thirds, exposing drowned canyons and a bathtub ring of mineral stain that serves as a national progress bar. Federal officials have spent the decade negotiating emergency agreements that shave a few hundred thousand acre-feet here and there, each announced as historic and each insufficient to close the structural gap. Arizona farmers lost allocations under the first tier of shortage, and one unincorporated community outside Scottsdale became a national emblem when its water supply was physically severed, leaving homeowners with wells that could not legally be replenished. The negotiation over post-2026 operating rules is the closest thing the American West has to a constitutional convention, and irrigated agriculture, the largest user by far, will end up being paid to fallow land. Groundwater is the other reservoir, invisible and therefore mined. The Ogallala aquifer underlies the Great Plains and supports a substantial share of national irrigation; in parts of Kansas more than a third of the usable water is already gone, and local management districts have begun rationing. California’s Central Valley sank as much as a foot in some years as farmers drilled during drought, and a 2014 groundwater law now forces retirement of farmland, because there is less water than there are fields. Cities inherit pipes older than their populations. Flint’s lead crisis poisoned a hundred thousand people and took years to become official; Jackson’s system failed repeatedly, leaving a state capital on boil notices; Newark replaced tens of thousands of lead lines in a hurry and became the counterexample. The pattern never varies much — deferred maintenance, fiscal squeeze, emergency, then a federal cheque arriving after the damage. Electricity has its own version of the same story and it is more acute, because demand had been flat for fifteen years and then stopped being flat. A winter storm in Texas in 2021 knocked out power to more than four million homes and killed between two hundred and two hundred and fifty people, most quietly, from hypothermia in houses that could not be heated. The state’s grid operator, celebrated for its independence from federal oversight, became the centre of a national argument about whether reliability is worth the price of connection, and then faced summer after summer of record demand. The new load is data. Machine-learning clusters and cloud campuses draw power like small industrial cities, and the concentration is extreme: a handful of counties in northern Virginia host more data-centre floor space than most nations. Regional capacity auctions cleared at prices several times the previous year’s, and that translates directly into household bills. Grid operators who spent a decade planning for retirements are now planning for growth nobody had anticipated, and utilities are extending the life of coal and gas plants they had scheduled to close. Water enters the calculation too, since a large campus can consume millions of gallons a day for cooling, and the newest facilities in the South have been sited beside rivers for exactly that reason, sometimes with local residents noting that the intake is upstream and the discharge is not. Three consequences are close to settled. Interstate water litigation will reach the Supreme Court, because the compact’s ambiguities have never been fully tested and the parties now have irreconcilable needs; the Southwest will undergo a compression in which irrigated acreage, golf courses and population growth negotiate against one another, with the third usually losing; and electricity pricing becomes the dominant household cost story, displacing petrol, because the grid is being asked to run a century-old country and a brand-new compute economy on transmission lines that are largely middle-aged. Water and power do not negotiate. * I lived in Black Mountain, near Asheville North Carolina when Hurricane Helene caused flooding and mudslides. Excerpts from: 10 Warnings Experts Have Issued About America’s Future by John Walter, Oct. 21, 2026 -------------------- My own present efforts for Climate Change awareness and building community is to join a book group of other Unitarian Universalists on line to discuss Radically Reframing Climate Change: A Guide to Saving Ourselves by Will Hackman. I don't have the book yet, but will start as soon as it arrives, after ordering from a local bookstore. (I haven't done so yet because of the rain storms on Oct. 22 when I wrote this. But I will as soon as possible.) I also admit to beginning a climate conversation at a recent social event, where the question started with "What's the plan following the midterm elections when the Democrats win?" I continue to bring that question around to how will climate change issues be addressed? Funded? Talked about more? If we don't help this earth - healthier than today - all the efforts to just remove the damages made in our government will not bring any improvement from two years ago when the craziness began. Fossil fuels must be addressed! Farming support and practices need attention. Ecological and environmental focus must become part of the norm. Stopping all the uses of fossil fuels. Saving our waters. Sustainability is a word needing to be on platforms for candidates for offices. How will we see our grandchildren's lives if we don't pay attention to climate change issues?  —————-
