Can rights of nature laws make a difference? In Ecuador, they already are

Can rights of nature laws make a difference? In Ecuador, they already are

Katie Surma writes: Until recently, so-called “rights of nature” provisions that confer legal rights to rivers, forests and other ecosystems have been mostly symbolic. But late last year, Ecuador’s top court changed that. In a series of court decisions, the Constitutional Court translated the country’s 2008 constitutional rights of nature provisions into reality, throwing the future of the country’s booming mining and oil industries into question. The most important of the decisions came in the Los Cedros case, where the…

World spends $1.8tn a year on subsidies that harm environment, study finds

World spends $1.8tn a year on subsidies that harm environment, study finds

The Guardian reports: The world is spending at least $1.8tn (£1.3tn) every year on subsidies driving the annihilation of wildlife and a rise in global heating, according to a new study, prompting warnings that humanity is financing its own extinction. From tax breaks for beef production in the Amazon to financial support for unsustainable groundwater pumping in the Middle East, billions of pounds of government spending and other subsidies are harming the environment, says the first cross-sector assessment for more…

The staggering ecological impacts of computation and the Cloud

The staggering ecological impacts of computation and the Cloud

Steven Gonzalez Monserrate writes: Screens brighten with the flow of words. Perhaps they are emails, hastily scrawled on smart devices, or emoji-laden messages exchanged between friends or families. On this same river of the digital, millions flock to binge their favorite television programming, to stream pornography, or enter the sprawling worlds of massively multiplayer online roleplaying games, or simply to look up the meaning of an obscure word or the location of the nearest COVID-19 testing center. Whatever your query,…

U.S. sea levels will rise rapidly in the next 30 years, new report shows

U.S. sea levels will rise rapidly in the next 30 years, new report shows

CNN reports: A new report provides an alarming forecast for the US: Sea level will rise as much in the next 30 years as it did in the past 100 — increasing the frequency of high-tide flooding, pushing storm surge to the extreme and inundating vulnerable coastal infrastructure with saltwater. The interagency report, led by the National Oceanic and Atmospheric Administration, shows how scientists are increasingly confident that US coasts will see another 10 to 12 inches of sea level…

Wood burners emit more particle pollution than traffic, UK data shows

Wood burners emit more particle pollution than traffic, UK data shows

The Guardian reports: Wood burning in homes produces more small particle pollution than all road traffic in the UK, according to revised government data. The new data significantly cuts the estimated proportion of small particle pollution that comes from wood burners from 38% to 17%. But wood burning pollution remains a “major contributor” to particle pollution, another government report said. Road transport is responsible for 13% of particle pollution. The data shows tiny particle pollution, called PM2.5, produced by wood…

Pharmaceutical drugs have dangerously polluted the world’s rivers, scientists warn

Pharmaceutical drugs have dangerously polluted the world’s rivers, scientists warn

The Guardian reports: Humanity’s drugs have polluted rivers across the entire world and pose “a global threat to environmental and human health”, according to the most comprehensive study to date. Pharmaceuticals and other biologically active compounds used by humans are known to harm wildlife and antibiotics in the environment drive up the risk of resistance to the drugs, one of the greatest threats to humanity. The scientists measured the concentration of 61 active pharmaceutical ingredients (APIs) at more than 1,000…

Conservation has a human rights problem. Can the new UN biodiversity plan solve it?

Conservation has a human rights problem. Can the new UN biodiversity plan solve it?

Inside Climate News reports: For decades, if not centuries, Maasai cattle farmers in Northern Tanzania have reared their animals alongside iconic wildlife species like cheetahs, lions and black rhinos. But that may change this year for a Maasai community living in the Ngorongoro Conservation Area, a park adjacent to Serengeti National Park and about the size of Rhode Island and Delaware combined. The Tanzanian government, citing the growth in population of the Maasai and their cattle as the main threat…

How fires across the world have grown weirder

How fires across the world have grown weirder

Daniel Immerwahr writes: The hundreds of bush fires that hit southern Australia on 7 February 2009 felt, according to witnesses, apocalyptic. It was already hellishly hot that day: 46.4C in Melbourne. As the fires erupted, day turned to night, flaming embers the size of pillows rained down, burning birds fell from the trees and the ash-filled air grew so hot that breathing it, one survivor said, was like “sucking on a hairdryer”. More than 2,000 homes burned down, and 173…

Extreme heat in oceans ‘passed point of no return’ in 2014

Extreme heat in oceans ‘passed point of no return’ in 2014

The Guardian reports: Extreme heat in the world’s oceans passed the “point of no return” in 2014 and has become the new normal, according to research. Scientists analysed sea surface temperatures over the last 150 years, which have risen because of global heating. They found that extreme temperatures occurring just 2% of the time a century ago have occurred at least 50% of the time across the global ocean since 2014. In some hotspots, extreme temperatures occur 90% of the…

The great Amazon land grab – how Brazil’s government is turning public land private, clearing the way for deforestation

The great Amazon land grab – how Brazil’s government is turning public land private, clearing the way for deforestation

A satellite captured large and small deforestation patches in Amazonas State in 2015. The forest loss has escalated since then. USGS/NASA Landsat data/Orbital Horizon/Gallo Images/Getty Images By Gabriel Cardoso Carrero, University of Florida; Cynthia S. Simmons, University of Florida, and Robert T. Walker, University of Florida Imagine that several state legislators decide that Yellowstone National Park is too big. Also imagine that, working with federal politicians, they change the law to downsize the park by a million acres, which they…

Rare and ancient trees are key to a healthy forest

Rare and ancient trees are key to a healthy forest

Science reports: About 800 years ago, a giant oak tree in England’s Sherwood Forest helped shelter Robin Hood from the corrupt sheriff of Nottingham. Though the tale is likely a myth, the tree is not: It still stands as one of the world’s oldest oaks. Such ancient trees—some dating back more than 3000 years—are key to the survival of their forests, new research shows. Rare trees—some so scarce scientists have yet to find them—are also critical to forest health, another…

A federal judge canceled major oil and gas leases over climate change

A federal judge canceled major oil and gas leases over climate change

NPR reports: Late last year, just days after pledging to cut fossil fuels at international climate talks in Glasgow, Scotland, the Biden administration held the largest oil and gas lease sale in U.S. history. On Thursday, a federal judge invalidated that sale in the Gulf of Mexico, saying the administration didn’t adequately consider the costs to the world’s climate. The administration used an analysis conducted under former President Donald Trump that environmental groups alleged was critically flawed. The decision represents…

The Great Unconformity has baffled geologists for a century

The Great Unconformity has baffled geologists for a century

Motherboard reports: Scientists can reconstruct incredible details about bygone eras in Earth’s history using fossils, rocks, and other clues preserved in its crust. But sometimes, the absence of geological records is just as telling as their presence. The Great Unconformity, a missing chunk of time that appears in rocks across the world, is the ultimate example of this phenomenon. This giant lapse in Earth’s memory exceeds one billion years in some places, resulting in 550 million-year-old rocks sitting atop ancient…

Earth is now a coalmine, and every wild bird is a canary

Earth is now a coalmine, and every wild bird is a canary

Kim Heacox writes: When the poet Mary Oliver wrote “Instructions for living a life,” she reminded us: “Pay attention. Be astounded. Tell about it.” This past autumn, wildlife officials announced that a bird, a male bar-tailed godwit, flew nonstop across the Pacific Ocean 8,100 miles from Alaska to Australia in just under 10 days. Fitted with a small solar-powered satellite tag, the godwit achieved “a land bird flight record”. But of course godwits have been doing this for centuries. Come…

Did a mega drought topple empires 4,200 years ago?

Did a mega drought topple empires 4,200 years ago?

Nature reports: The missing earthworms were a sign. As archaeologist Harvey Weiss and his colleagues excavated a site in northeast Syria, they found a buried layer of wind-blown silt so barren there was hardly any evidence of earthworms at work during that ancient era. Something drastic had happened thousands of years ago — something that choked the land with dust for decades, leaving a blanket of soil too inhospitable even for earthworms. The drought hit in roughly 2200 BC, when the…

Scientists find hints of a hidden mass extinction 30 million years ago

Scientists find hints of a hidden mass extinction 30 million years ago

Inside Science reports: Nearly two-thirds of mammal species in Africa and the Arabian Peninsula may have died off about 30 million years ago, a mass extinction that escaped detection for decades until now, a new study finds. During a time span known as the Eocene-Oligocene transition between 40 million and 34 million years ago, Earth’s climate shifted dramatically, with the planet growing cooler, ice sheets expanding and sea levels dropping worldwide. During the Eocene, Antarctica was covered by lush forests,…
