According to new data from the Rhodium Group analyzed by ProPublica and The New York Times Magazine, warming temperatures and changing rainfall will drive agriculture and temperate climates northward, while sea level rise will consume coastlines and dangerous levels of humidity will swamp the Mississippi River valley. Taken with other recent research showing that the most habitable climate in North America will shift northward and the incidence of large fires will increase across the country, this suggests that the climate crisis will profoundly interrupt the way we live and farm in the United States. See how the North American places where humans have lived for thousands of years will shift and what changes are in store for your county. - ProPublica

In the once-seedy district of Soho, about 10 minutes’ walk from New Scientist‘s London offices, a pump, a plaque and a pub commemorate one of the greatest ever breakthroughs in human history: a decisive step made almost 200 years ago towards conquering infectious disease. Our current global health crisis is a reminder of how little we want to return to the days when deadly infections carried away most of us. Yet also in some way, advances back then were a first step on a path towards planetary perdition. The success against infectious disease, alongside other major developments, dramatically improved our survival and set humanity’s numbers soaring, from little more than 1.25 billion people back then to 7.7 billion now. Now, climate change, biodiversity loss, the degradation of the biosphere and, yes, coronavirus are forcing us to consider the legacy of that success. The pandemic is becoming the latest focus for an old, uniquely contentious question: are there just too many of us on the planet? - New Scientist

In the 1960s, fears of overpopulation sparked campaigns for population control. But whatever became of the population bomb?- NYTimes

Every one and a half minutes, a child is born somewhere in Texas. At one hospital in North Texas, 107 babies were delivered over 96 hours this summer, shattering local records. At a hospital in San Antonio, more than 1,200 babies have been born this year, up nearly 30 percent since 2018. One of the nation’s fastest-growing states ends each day with about 1,000 more Texans, a net gain primarily made up of newborns. - NYTimes

Within eight years, Delhi is expected to surpass Tokyo to become the largest megalopolis in the world, making it the epicenter of a global phenomenon: Fifteen years ago, most of the world’s population lived in the countryside, and today, most live in cities. The U.N. says two-thirds of people will live in urban areas by 2050. Delhi is one of the most extreme barometers of this transformation. - NYTimes

China announced on Monday that its birthrate plummeted for a fifth straight year in 2021, moving the world’s most populous country closer to the potentially seismic moment when its population will begin to shrink, and hastening a demographic crisis that could undermine its economy and even its political stability. The falling birthrate, coupled with the increased life expectancy that has accompanied China’s economic transformation over the last four decades, means the number of people of working age, relative to the growing number of people too old to work, has continued to decline. That could result in labor shortages, which could hamper economic growth, and reduce the tax revenue needed to support an aging society.- NYTimes

Agriculture already uses almost half of the world’s vegetated land. It consumes 90 percent of all the water used by humanity and generates one-quarter of the annual global emissions that are causing global warming. And yet of the seven billion people living today, 820 million are undernourished because they don’t have access to—or can’t afford—an adequate diet.  “We have to produce 30 percent more food on the same land area, stop deforestation, [and] cut carbon emissions for food production by two-thirds,” says Waite in an interview.  All of that must be done while reducing poverty levels and the loss of natural habitat, preventing freshwater depletion, and cutting pollution as well as other environmental impacts of farming.​- National Geographic

The vast majority of land on Earth — a staggering 97 percent — no longer qualifies as ecologically intact, according to a sweeping survey of Earth’s ecosystems. Over the last 500 years, too many species have been lost, or their numbers reduced, researchers report April 15 in Frontiers in Forests and Global Change. Of the few fully intact ecosystems, only about 11 percent fall within existing protected areas, the researchers found. Much of this pristine habitat exists in northern latitudes, in Canada’s boreal forests or Greenland’s tundra, which aren’t bursting with biodiversity. But chunks of the species-rich rainforests of the Amazon, Congo and Indonesia also remain intact. - Science News

Limited access to clean water remains a struggle for millions of Americans. And lack of water access is expected to become an even greater problem in the coming years across the U.S. and around the world. In West Virginia, many households in McDowell County rely on collecting water from fresh springs, which might freeze over in the winter or run dry in the summer. Bob McKinney is the Appalachia Water Project manager for DigDeep, a nonprofit that works to provide water to Americans who wouldn't otherwise have access. He says he estimates that about half of McDowell's population doesn't have reliable running water in their homes. - CBS News

Warming waters & worsening storms caused by climate change have weakened the kelp forests. Sewage & sediment spill onto them from cities on the shore. Most significantly, the demise of important predators such as otters and sea stars has led to an explosion in the population of sea urchins, which eat kelp. Huge swaths of underwater forest are being replaced by urchin “barrens” — denuded landscapes, desolate but for the spiky, spherical animals. Eventually, even the urchins start to starve.  Humans have put our planet on a path toward disaster. If people keep polluting at the current rate, scientists say, climate change will cause prolonged droughts, devastating storms, collapsing ecosystems and vanishing species. Coastal cities will be deluged by sea level rise; widespread food and water shortages will lead to the deaths of millions. To avoid this fate, civilization must rapidly transform — cutting carbon emissions 40 percent by 2030 and reaching “net zero” by the middle of the century. - Washington Post
