Unheralded environmentalist: Jimmy Carter’s green legacy

Unheralded environmentalist: Jimmy Carter’s green legacy

Kai Bird writes: The angry Alaskans gathered in Fairbanks to burn the president’s effigy. It was early December 1978 and President Jimmy Carter was that unpopular in Alaska. A few days earlier Carter had issued an unusual executive order, designating 56 million acres of Alaskan wilderness as a national monument. He did so unilaterally, using a little known 1906 Antiquities Act that ostensibly gave the president the executive power to designate buildings or small plots of historical sites on federal…

How to buy a piece of a lawsuit and impoverish a country

How to buy a piece of a lawsuit and impoverish a country

Inside Climate News reports: When a foreign mining company sued Greenland in 2022, the government’s lead lawyer thought he was prepared. Paw Fruerlund had handled similar cases before, and he believed the law and facts were on his side. When he arrived at one of the first hearings, however, Fruerlund stared across the table at 12 corporate lawyers from two firms representing his opponent, an Australian company called Greenland Minerals. There were so many, they spilled across two rows of…

Our morals change with the seasons

Our morals change with the seasons

Alice Sun writes: The seasons have been shown to influence many elements of our psyches and behavior: mood, color preferences, how charitable we are, even cognitive performance. But recently, researchers found they may also affect what we tend to consider among our most profoundly held convictions: how we decide what is right and wrong. A team of researchers looked at a decade’s worth of responses to an online survey about morals and analyzed how these responses changed from one season…

To escape extreme heat, farmers and fisherfolk worldwide are adopting overnight hours

To escape extreme heat, farmers and fisherfolk worldwide are adopting overnight hours

Modern Farmer reports: Every morning, for years, Josana Pinto da Costa would venture out onto the waterways lining Óbidos, Brazil, in a small fishing boat. She would glide over the murky, churning currents of the Amazon River Basin, her flat nets bringing in writhing hauls as the sun ascended into the cerulean skies above. Scorching temperatures in the Brazilian state of Pará have now made that routine unsafe. The heat has “been really intense” this year, said Pinto da Costa…

The alchemy that powers the modern world

The alchemy that powers the modern world

December 13, 2024 by Sarah Scoles The astronomer Carl Sagan once said, “If you wish to make an apple pie from scratch, you must first invent the universe.” That universe must then invent the first atoms, which will make up the first stars, which will fuse those initial elements into larger ones. Stars will explode and die and crash into each other, those cataclysms building heavier elements. Eventually, billions of years later, the universe will produce an Earth whose insides…

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…

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…
