New set of human rights principles aims to end displacement and abuse of Indigenous people through ‘fortress conservation’

New set of human rights principles aims to end displacement and abuse of Indigenous people through ‘fortress conservation’

Many protected areas, including California’s Yosemite National Park, displaced Indigenous people in the name of protecting wildlands. Matthew Dillon/Flickr By John H. Knox, Wake Forest University For more than a century, conservationists have worked to preserve natural ecosystems by creating national parks and protected areas. Today the Earth faces a global biodiversity crisis, with more than 1 million species at risk of extinction. This makes it even more important to conserve places where at-risk species can thrive. In 2022, governments…

As climate change melts permafrost, microbes that we have never been exposed to will emerge

As climate change melts permafrost, microbes that we have never been exposed to will emerge

Valerie Brown writes: The popular image of the Arctic is as a “frozen North,” which it was for all of human history until a couple of centuries ago. In that view, intrepid explorers and scientists clatter over tundra and ice roads in dogsleds and decrepit trucks, risking everything to bring back important samples and wild tales of howling winds. But this vision is growing passé. The Arctic is warming four times as fast as the global average. While there are…

Human-caused ocean warming intensified recent hurricanes

Human-caused ocean warming intensified recent hurricanes

Yale Climate Connections reports: Human-caused climate change boosted the wind speeds of recent Atlantic hurricanes, making them more damaging and costly, according to a pair of scientific reports released today. Research published in the journal Environmental Research: Climate, “Human-caused ocean warming has intensified recent hurricanes,” found that between 2019 and 2023, the maximum sustained winds of Atlantic hurricanes were 19 mph (31 km/h) higher because of human-caused ocean warming. And a parallel report by Climate Central, a nonprofit scientific research…

Hiker discovers first trace of entire prehistoric ecosystem in Italian Alps

Hiker discovers first trace of entire prehistoric ecosystem in Italian Alps

The Guardian reports: A hiker in the northern Italian Alps has stumbled across the first trace of what scientists believe to be an entire prehistoric ecosystem, including the well-preserved footprints of reptiles and amphibians, brought to light by the melting of snow and ice induced by the climate crisis. The discovery in the Valtellina Orobie mountain range in Lombardy dates back 280 million years to the Permian period, the age immediately prior to dinosaurs, scientists say. Claudia Steffensen, from Lovero,…

Polar bears are getting horrific injuries because of climate change, researchers say

Polar bears are getting horrific injuries because of climate change, researchers say

Live Science reports: Polar bears are developing horrific wounds on their paws due to changing ice conditions in the Arctic, a new study reports. In the most severe cases, researchers describe two bears with crippling, dinner plate-size balls of ice stuck to their feet. Beneath the ice balls, the bears’ paw pads were covered in deep, bleeding cuts. “I’d never seen that before,” study lead author Kristin Laidre, a marine ecologist and associate professor at the University of Washington, said…

Humanity is on the verge of ‘shattering Earth’s natural limits’, say experts in biodiversity warning

The Guardian reports: Humanity is “on the precipice” of shattering Earth’s limits, and will suffer huge costs if we fail to act on biodiversity loss, experts warn. This week, world leaders meet in Cali, Colombia, for the Cop16 UN biodiversity conference to discuss action on the global crisis. As they prepare for negotiations, scientists and experts around the world have warned that the stakes are high, and there is “no time to waste”. “We are already locked in for significant…

Half of all global food threatened by growing water crisis, report says

Half of all global food threatened by growing water crisis, report says

NBC News reports: The world has a worsening water crisis and half of all food production will be at risk of failure by the middle of this century. That’s the worrying message from a report released Wednesday by a major international study. Half of the world’s population already faces water scarcity and that proportion is growing too, according to the Global Commission on the Economics of Water, which is funded by the Dutch government and facilitated by the Organization for…

Rain may have helped form the first cells, kick-starting life as we know it

How did early cells keep themselves distinct while allowing for some amount of exchange? UChicago Pritzker School of Molecular Engineering/Peter Allen, Second Bay Studios, CC BY-ND By Aman Agrawal, University of Chicago Pritzker School of Molecular Engineering Billions of years of evolution have made modern cells incredibly complex. Inside cells are small compartments called organelles that perform specific functions essential for the cell’s survival and operation. For instance, the nucleus stores genetic material, and mitochondria produce energy. Another essential part…

Trees and land absorbed almost no CO2 last year. Is nature’s carbon sink failing?

Trees and land absorbed almost no CO2 last year. Is nature’s carbon sink failing?

The Guardian reports: It begins each day at nightfall. As the light disappears, billions of zooplankton, crustaceans and other marine organisms rise to the ocean surface to feed on microscopic algae, returning to the depths at sunrise. The waste from this frenzy – Earth’s largest migration of creatures – sinks to the ocean floor, removing millions of tonnes of carbon from the atmosphere each year. This activity is one of thousands of natural processes that regulate the Earth’s climate. Together,…

Researchers parse the future of plankton in an ever-warmer world

Researchers parse the future of plankton in an ever-warmer world

Nicola Jones writes: Across the world’s oceans, an invisible army of tiny organisms has a supersized impact on the planet. Plankton are at the base of the ocean food chain, feeding fish that feed billions of people. They are responsible for half of the world’s oxygen supply and half of our planet’s annual carbon sink. Miniscule but powerful, their presence can help or hinder ecosystems — by soaking up greenhouse gas, for example, or by spewing toxins. Where plankton live,…

Navigation strategies studied in a lab may not replicate in real life

Sujata Gupta writes: On a trip to Siberia in 2019, cognitive scientist Pablo Fernandez Velasco attended a raffle drawing with the region’s Evenki reindeer herders. Prizes included a soccer ball, tea, a portable radio, a GPS unit and other knickknacks. A herder in Velasco’s group won the GPS. “I thought [that] was one of the fancier prizes,” says Velasco, of the University of York in England. “He was crestfallen.” The herder, who had been eyeing the radio, had no use…

The Northern Lights make music

The Northern Lights make music

Caspar Henderson writes: Old stories about the Northern Lights, or aurora borealis, show the full play of human imagination at work across the sky. In Greenland some said the lights were the spirits of children who had died at birth but were now dancing in the heavens. Others said they were made by spirits playing ball with the skull of a walrus—or by walrus spirits kicking around human skulls. To the Algonquin people of eastern Canada, the lights were the…

Hurricane Helene aftermath: Untold stories from the mountains

Hurricane Helene aftermath: Untold stories from the mountains

Since Hurricane Helene hammered Western North Carolina, media coverage of the aftermath has focused on the impact felt in Asheville. Having lived there from 2002 until 2020, I know the area very well. The stories from Asheville, Swannanoa, Black Mountain, and all the small towns dotted around Buncombe and the surrounding counties are heartbreaking. But beyond the towns, there are so many communities that are even smaller — places that might catch some momentary media attention because of an heroic…
