Depleted under Trump, a ‘traumatized’ EPA struggles with its mission

Depleted under Trump, a ‘traumatized’ EPA struggles with its mission

The New York Times reports: The nation’s top environmental agency is still reeling from the exodus of more than 1,200 scientists and policy experts during the Trump administration. The chemicals chief said her staff can’t keep up with a mounting workload. The enforcement unit is prosecuting fewer polluters than at any time in the past two decades. And now this: the stressed-out, stretched-thin Environmental Protection Agency is scrambling to write about a half dozen highly complex rules and regulations that…

New data show that light pollution is rapidly obscuring the night sky

New data show that light pollution is rapidly obscuring the night sky

Science News reports: The night sky has been brightening faster than researchers realized, thanks to the use of artificial lights at night. A study of more than 50,000 observations of stars by citizen scientists reveals that the night sky grew about 10 percent brighter, on average, every year from 2011 to 2022. In other words, a baby born in a region where roughly 250 stars were visible every night would see only 100 stars on their 18th birthday, researchers report…

An ancient farming technique could stabilize crop yields under changing conditions

An ancient farming technique could stabilize crop yields under changing conditions

Science Alert reports: As climates around the world grow harsher and increasingly unpredictable, concerns are increasing over our world’s food security. Already, yields of staple crops like maize and wheat are dropping in low-latitude tropical regions and in dry and drying regions such as African drylands and parts of the Mediterranean. Wealthy countries are far from immune. Australia experienced almost a 30 percent crop yield decline between 1990 and 2015 due to reduced rainfall. While studying food diversity in 2011,…

Why we will never be able to live on another planet

Why we will never be able to live on another planet

Arwen E Nicholson and Raphaëlle D Haywood write: For decades, children have grown up with the daring movie adventures of intergalactic explorers and the untold habitable worlds they find. Many of the highest-grossing films are set on fictional planets, with paid advisors keeping the science ‘realistic’. At the same time, narratives of humans trying to survive on a post-apocalyptic Earth have also become mainstream. Given all our technological advances, it’s tempting to believe we are approaching an age of interplanetary…

Europe is winning the energy war with Putin, but food prices are likely to rise

Europe is winning the energy war with Putin, but food prices are likely to rise

Politico reports: Halfway through the first winter of Europe’s energy war with Russia, only one side is winning. When Vladimir Putin warned in September that Europeans would “freeze” if the West stuck to its energy sanctions against Russia, Moscow’s fossil fuel blackmail appeared to be going exactly to plan. European wholesale gas prices were north of €200 per megawatt hour, around 10 times higher than they had been for most of 2021. Plans were drawn up to cut gas demand…

Human noise drowns out communication between dolphins

Human noise drowns out communication between dolphins

The New York Times reports: Mammals in the ocean swim through a world of sound. But in recent decades, humans have been cranking up the volume, blasting waters with noise from shipping, oil and gas exploration and military operations. New research suggests that such anthropogenic noise may make it harder for dolphins to communicate and work together. When dolphins cooperated on a task in a noisy environment, the animals were not so different from city dwellers on land trying to…

Rare earth mining may be key to our renewable energy future. But at what cost?

Rare earth mining may be key to our renewable energy future. But at what cost?

Carolyn Gramling writes: In spring 1949, three prospectors armed with Geiger counters set out to hunt for treasure in the arid mountains of southern Nevada and southeastern California. In the previous century, those mountains yielded gold, silver, copper and cobalt. But the men were looking for a different kind of treasure: uranium. The world was emerging from World War II and careening into the Cold War. The United States needed uranium to build its nuclear weapons arsenal. Mining homegrown sources…

Scientists report a dramatic drop in the extent of Antarctic sea ice

Scientists report a dramatic drop in the extent of Antarctic sea ice

Inside Climate News reports: The new year started with the familiar refrain of climate extremes, as scientists with the National Snow and Ice Data Center reported Jan. 3 that the sea ice around Antarctica dropped to its lowest extent on record for early January. “The current low sea ice extent … is extreme, and frankly we are working to understand it,” said Antarctica expert Ted Scambos, a senior research scientist with the Earth Science and Observation Center at the University…

Oil, gas exploration and deforestation threaten Africa’s great carbon sink

Oil, gas exploration and deforestation threaten Africa’s great carbon sink

Olivia Rosane writes: In the center of the African continent, an immense and vital forest currently thrives. As the world’s second-largest tropical rainforest, the Congo Basin covers six countries and around 500 million acres–an area one-fourth the size of the contiguous U.S. It is a haven for both human and natural diversity, hosting more than 150 different ethnic groups and one-fifth of all Earth’s species. It directly supports the livelihoods of the 60 million people who live in or near…

The vanishing wild: Life on Earth in midst of sixth mass extinction, scientists say

The vanishing wild: Life on Earth in midst of sixth mass extinction, scientists say

  60 Minutes reports: In what year will the human population grow too large for the Earth to sustain? The answer is about 1970, according to research by the World Wildlife Fund. In 1970, the planet’s 3 and a half billion people were sustainable. But on this New Year’s Day, the population is 8 billion. Today, wild plants and animals are running out of places to live. The scientists you’re about to meet say the Earth is suffering a crisis…

Nearly 200 countries approve a biodiversity accord enshrining human rights and the ‘rights of nature’

Nearly 200 countries approve a biodiversity accord enshrining human rights and the ‘rights of nature’

Inside Climate News reports: Nearly 200 countries have signed off on an agreement that embeds the promotion of human rights and the “rights of nature” into a plan to protect and restore biodiversity through 2030. The 14-page document, while nonbinding, was adopted on Dec. 19, 2022 at COP15, a 12-day conference convened in Montreal under the auspices of the U.N. Convention of Biological Diversity. It is the first international agreement to give credence to a growing movement that recognizes that…

Brazil’s Lula picks Amazon defender for environment minister

Brazil’s Lula picks Amazon defender for environment minister

The Associated Press reports: Brazil´s President-elect Luiz Inácio Lula da Silva announced Thursday that Amazon activist Marina Silva will be the country´s next minister of environment. The announcement indicates the new administration will prioritize cracking down on illegal deforestation even if it means running afoul of powerful agribusiness interests. Both attended the recent U.N. climate conference in Egypt, where Lula promised cheering crowds “zero deforestation” in the Amazon, the world’s largest rainforest and a key to fighting climate change, by…

As a climate change-induced drought wears on, wildlife, livestock and people face deadly consequences

As a climate change-induced drought wears on, wildlife, livestock and people face deadly consequences

Georgina Gustin writes: A wildebeest has toppled into a ditch at the edge of a dusty track, its shoe-box-shaped head twisted upward, a single gaping chomp out of its flank. Isack Marembe and Kisham Makui study the animal’s body and everything around it, doing a roadside postmortem. “A hyena,” Marembe says. But the culprit wasn’t a hyena. The hyena just happened to pass by and take a bite from the dead wildebeest’s side. The killer was—it is—an enduring drought driven…

Life in Fukushima offers a glimpse into our contaminated future

Life in Fukushima offers a glimpse into our contaminated future

Maxime Polleri writes: As a farmer, Atsuo Tanizaki did not care much for the state’s maps of radioactive contamination. Colour-coded zoning restrictions might make sense for government workers, he told me, but ‘real’ people did not experience their environment through shades of red, orange and green. Instead, they navigated the landscape one field, one tree, one measurement at a time. ‘Case by case,’ he said, grimly, as he guided me along the narrow paths that separated his rice fields, on…

Degrowth can work — here’s how science can help

Degrowth can work — here’s how science can help

Jason Hickel et al, write: The global economy is structured around growth — the idea that firms, industries and nations must increase production every year, regardless of whether it is needed. This dynamic is driving climate change and ecological breakdown. High-income economies, and the corporations and wealthy classes that dominate them, are mainly responsible for this problem and consume energy and materials at unsustainable rates. Yet many industrialized countries are now struggling to grow their economies, given economic convulsions caused…

British place names resonate with the song of missing birds

British place names resonate with the song of missing birds

Michael J Warren writes: In one of the oldest poems in English literature, there is a beautiful moment when a lone sailor, battling against stormy winter seas and his troubled soul, describes how birds have replaced human company for him on the ‘ice-cold way’ – an admission that carries both comfort and sardonic misery. His entertainment is the ‘swan’s song’, men’s laughter is now ‘the gannet’s sound and curlew’s cry’, and the warming tonic of mead is echoed in the…
