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

California water officials have moved to stop Nestlé from siphoning millions of gallons of water out of California’s San Bernardino forest, which it bottles and sells as Arrowhead brand water, as drought conditions worsen across the state. The draft cease-and-desist order, which still requires approval from the California Water Resources Control Board, is the latest development in a protracted battle between the bottled water company and local environmentalists, who for years have accused Nestlé of draining water supplies at the expense of local communities and ecosystems. - HCN

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

Interstate water disputes are as American as apple pie. States often think a neighboring state is using more than its fair share from a river, lake or aquifer that crosses borders.  Currently the U.S. Supreme Court has on its docket a case between Texas, New Mexico and Colorado and another between Mississippi and Tennessee. The court has already ruled this term on cases pitting Texas against New Mexico and Florida against Georgia.  Climate stresses are raising the stakes. Rising temperatures require farmers to use more water to grow the same amount of crops. Prolonged and severe droughts decrease available supplies. Wildfires are burning hotter and lasting longer. Fires bake the soil, reducing forests’ ability to hold water, increasing evaporation from barren land and compromising water supplies. - HCN

Wracked by drought, climate change and overuse, a key reservoir on the Colorado River could sink to historically low levels later this year, new US government projections show, potentially triggering significant water cutbacks in some states as early as next year.  The projections released by the US Bureau of Reclamation show that Lake Mead, largest reservoir in the US and a vital water supply to millions across the Southwest, could fall later this year to its lowest levels since it was filled in the 1930s. - CNN

Just 10 miles off the coast of Los Angeles lurks an environmental disaster over 70 years in the making, which few have ever heard about... until now.   Working with little more than rumors and a hunch, curiosity guided David Valentine 3,000 feet below the ocean's surface. A few hours of research time and an autonomous robotic submersible unearthed what had been hidden since the 1940s: countless barrels of toxic waste, laced with DDT, littering the ocean floor in between Long Beach and Catalina Island. - CBS

Australia’s leading scientists made a significant global-scale declaration about the fight to deal with the climate crisis this week – but you could be forgiven if you missed it.  In what it described as a landmark report, the Australian Academy of Science painted a picture of what could happen to the country under 3C of global heating, including ecosystems made unrecognisable, food production being compromised and people’s ability to exist and survive in hotter and longer heatwaves regularly tested.  The central message? There is no time to wait.  But lying within the report was another substantial claim – that limiting global heating to 1.5° C was now “virtually impossible”. - Guardian

In Phoenix, two cities are emerging: one is water-rich, the other water-poor  Every two weeks, Dawn Upton floods her lawn. She treks into her back yard, twists open two valves big as dinner plates, and within minutes is ankle-deep in water.  “You have to have irrigation boots, girl,” she says during a video tour of her property in Mesa, a suburb of Phoenix, Arizona. She flips her camera to reveal green grass, then tilts her phone skyward at four towering palm trees. As she walks, she pans across pecan, pomegranate, and citrus trees – lemon, orange, a grapefruit sapling. A tortoise, between 80 and 100lb, lumbers toward her, chewing. “There’s Simba,” Upton says. “Hey buddy! What is that, Simba? You can’t eat it.” She pats him affectionately on the head. - Guardian

State officials are putting farmers in south-central Arizona on notice that the continuing drought means a “substantial cut" in deliveries of Colorado River water is expected next year.  A statement issued Friday by the state Department of Water Resources and the Central Arizona Project said an expected shortage declaration “will result in a substantial cut to Arizona’s share of the river, with reductions falling largely to central Arizona agricultural users." - AZ Family

Fossil fuel-backed anti-protest laws have been passed in 14 states and are making their way through statehouses in several more states, including six different bills in Minnesota, the only state with a big pipeline fight this year: Line 3. Researcher Connor Gibson joins to talk us through how this all started and where it's at. (36 minutes.  Warning: This will make you angry.)  - Drilled Podcast (
