Minnesota's Lower Sioux Indian Community is pioneering green building with its fully integrated hempcrete facility - a first in the countryWhen Earl Pendleton first heard about building houses out of hemp more than a decade ago, it seemed like a far-fetched idea.To start, it was still illegal to grow hemp - the non-psychoactive strain of Cannabis sativa - in the US. Importing it from overseas was prohibitively expensive. But Pendleton, a member of the Lower Sioux Indian Community, was intrigued by early research that showed hemp could be transformed into non-toxic construction materials that allow for faster build times and result in low-carbon, energy-efficient houses.

As the soundscape of the natural world began to disappear over 30 years, one man was listening and recording it allRead more: World faces deathly silence' of nature as wildlife disappears, warn expertsThe tale starts 30 years ago, when Bernie Krause made his first audio clip in Sugarloaf Ridge state park, 20 minutes' drive from his house near San Francisco. He chose a spot near an old bigleaf maple. Many people loved this place: there was a creek and a scattering of picnic benches nearby.As a soundscape recordist, Krause had travelled around the world listening to the planet. But in 1993 he turned his attention to what was happening on his doorstep. In his first recording, a stream of chortles, peeps and squeaks erupt from the animals that lived in the rich, scrubby habitat. His sensitive microphones captured the sounds of the creek, creatures rustling through undergrowth, and the songs of the spotted towhee, orange-crowned warbler, house wren and mourning dove.

The 2013 documentary Blackfish turned orca trainers into pariahs in the US. Now some are hitting it big in ChinaSome people spend a long time deciding what they want to do in life. Hazel McBride feels lucky that she's always known. As a child in Scotland, she watched a VHS tape of Free Willy on repeat. That was the first time she felt a connection with killer whales. The second time was at age eight, on a trip to SeaWorld Orlando in 2000. Shamu was the animal world's greatest celebrity, and in the US, SeaWorld ads were ubiquitous. Kids wanted to see the killer whales, and after they saw them, they told their parents they wanted to become killer whale trainers. McBride actually did it.It wasn't easy. Scotland didn't have a SeaWorld, or warm water, or anywhere, really, where McBride could get experience with marine mammals. She had horses she cared for, and she was on the national swim team - a modest start. She sent out volunteer applications to local zoos and worked with California sea lions at a safari park. She reached out to trainers online and one told her a psychology degree would help, so she got one. Continue reading...

Loss of intensity and diversity of noises in ecosystems reflects an alarming decline in healthy biodiversity, say sound ecologistsRead more: No birdsong, no water in the creek, no beating wings: how a haven for nature fell silentSounds of the natural world are rapidly falling silent and will become acoustic fossils" without urgent action to halt environmental destruction, international experts have warned.As technology develops, sound has become an increasingly important way of measuring the health and biodiversity of ecosystems: our forests, soils and oceans all produce their own acoustic signatures. Scientists who use ecoacoustics to measure habitats and species say that quiet is falling across thousands of habitats, as the planet witnesses extraordinary losses in the density and variety of species. Disappearing or losing volume along with them are many familiar sounds: the morning calls of birds, rustle of mammals through undergrowth and summer hum of insects. Continue reading...

Supreme court ruling left more than 90% of state's surface waters with no pollution protections, since they don't run continuouslyNew Mexico's rivers, which include the Rio Grande, Gila, San Juan and Pecos, are America's most threatened waterways, according to a new report. This is largely due to a 2023 US supreme court decision that left more than 90% of the state's surface waters without federal protections from industrial pollution, according to state officials.Virtually all the rivers in New Mexico are losing clean water protections," said Matt Rice, the south-west regional director of American Rivers, the conservation group that publishes the annual list. It has the most to lose, and the threat is particularly acute there." Continue reading...

Indigenous groups see hope in the environmentally friendly process of bioremediation. But will cities pay attention?It almost looked like a garden. In Taylor Yard, a former railyard near downtown Los Angeles, volunteers knelt down to tend to scrubby plants growing in neat rows under the sweltering sun.But beneath the concrete of the 60-acre site overlooking the Los Angeles River, the soils were soaked with an assortment of hazardous heavy metals and petrochemicals like lead, cadmium, diesel and benzene. As the volunteers worked to dig up entire plants for closer study - some with roots nearly 12ft deep - they wore protective gear and carefully avoided inhaling or touching the toxic soil. Even a brief exposure to the contaminants could cause serious health consequences. Continue reading...

Hairy-nosed otters and cats that catch fish are among the startling diversity of creatures making their home in threatened habitatsOne of the most comprehensive biodiversity surveys ever carried out in a mangrove forest has revealed that an astonishing array of wildlife makes its home in these key, threatened habitats.Hundreds of species - from bats to birds and fish to insects - were identified during the study of the Peam Krasop sanctuary and the adjacent Koh Kapik Ramsar reserve in Cambodia. Hairy-nosed otters, smooth-coated otters, large-spotted civets, long-tailed macaques and fishing cats, as well a wide range of bat species, were among the residents recorded by the survey, which was funded by the conservation group Fauna & Flora International. The variety of wildlife has staggered biologists. Continue reading...

Decision by European court of human rights around vulnerability of older women to heatwaves marks significant shiftA landmark legal ruling at the European court of human rights could open the floodgates for a slew of new court cases around the world, experts have said.The Strasbourg-based court said earlier this week that Switzerland's failure to do enough to cut its national greenhouse gas emissions was a clear violation of the human rights of a group of more than 2,000 older Swiss women. The women argued successfully that their rights to privacy and family life were being breached because they were particularly vulnerable to the health impacts of heatwaves. Continue reading...

Alliance says there's not enough ambition in proposed laws to prevent extinctions, as promised by the environment minister

Company is fighting Dutch court ruling that says it must emit 45% less CO2 by 2030 than in 2019Shell has argued that it lobbies for, not against, the energy transition" on the final day of its appeal against an important climate ruling.The fossil fuel company is fighting the decision of a Dutch court in 2021 that forces it to pump 45% less planet-heating CO into the atmosphere by 2030 than it did in 2019.

El Nino weather phenomenon has contributed to warm, dry conditions in US, leading to more fires much earlier in the yearThe US midwest typically spends the start of spring emerging from snow. But this year, after a warm winter left landscapes parched, the region instead was primed to burn. Hundreds of blazes ignited in recent months in states more accustomed to dealing with just dozens for this time of year, as extreme fire behavior defied seasonal norms.Experts say the unusually early and active fire season was a symptom of El Nino, a climate pattern characterized by warmer surface temperatures in the Pacific Ocean that was predicted to supercharge global heating and extreme weather. But the climate crisis turned up the dial, and helped create conditions in the midwest where winter temperature records were not only broken - they were smashed. Continue reading...

Millions of years ago, animals adapted to become warm-blooded amid huge climactic changes. Now scientists hope these clues from the past could help us understand what lies aheadIn Chicago's Field Museum, behind a series of access-controlled doors, are about 1,500 dinosaur fossil specimens. The palaeobiologist Jasmina Wiemann walks straight past the bleached leg bones - some as big as her - neither does she glance at the fully intact spinal cord, stained red by iron oxides filling the spaces where there was once organic material. She only has eyes for the deep chocolate-brown fossils: these are the ones containing preserved organic matter - bones that offer unprecedented insights into creatures that went extinct millions of years ago.Wiemann is part of the burgeoning field of conservation palaeobiology, where researchers are looking to the deep past to predict future extinction vulnerability. At a time when humans could be about to witness a sixth mass extinction, studying fossil records is particularly useful for understanding how the natural world responded to problems before we arrived: how life on Earth reacted to environmental change over time, how species adapted to planet-scale temperature changes, or what to expect when ocean geochemical cycles change.

Government recovery fund stipulates affected areas must be less than 150 metres from a main' riverFarmers who have their entire cropping land submerged underwater have found they are ineligible for a government flooding hardship fund - because their farms are too far from a major river.According to the Met Office, 1,695.9mm of rain fell from October 2022 to March 2024, the highest amount for any 18-month period in England since the organisation started collecting comparable data in 1836. Scientists have said climate breakdown is likely to cause more intense periods of rain in the UK. Continue reading...

Rules celebrated for reducing exposures, but experts say it's not enough and will lead to an endless game of Whac-A-Mole'Strong new limits for some PFAS compounds in drinking water set by the US Environmental Protection Agency this week are being celebrated for how far they go in reducing exposures to the dangerous chemicals.But public health advocates say the rules merely represent a first step that is limited in its impact on the broader PFAS crisis because they do not directly prevent more pollution or force the chemical industry to pay for cleanup.
