Court blocks a vast Alaskan oil drilling project, citing climate dangers

The New York Times reports: A federal judge in Alaska on Wednesday blocked construction permits for an expansive oil drilling project on the state’s North Slope that was designed to produce more than 100,000 barrels of oil a day for the next 30 years. The multibillion-dollar plan, known as Willow, by the oil giant ConocoPhillips had been approved by the Trump administration and legally backed by the Biden administration. Environmental groups sued, arguing that the federal government had failed to…

How water shortages are brewing wars

How water shortages are brewing wars

Sandy Milne writes: Speaking to me via Zoom from his flat in Amsterdam, Ali al-Sadr pauses to take a sip from a clear glass of water. The irony dawning on him, he lets out a laugh. “Before I left Iraq, I struggled every day to find clean drinking water.” Three years earlier, al-Sadr had joined protests in the streets of his native Basra, demanding the authorities address the city’s growing water crisis. “Before the war, Basra was a beautiful place,”…

First-ever water cuts declared for Colorado River in historic drought

First-ever water cuts declared for Colorado River in historic drought

CNN reports: The federal government on Monday declared a water shortage on the Colorado River for the first time, triggering mandatory water consumption cuts for states in the Southwest, as climate change-fueled drought pushes the level in Lake Mead to unprecedented lows. Lake Mead, the largest reservoir in the US by volume, has drained at an alarming rate this year. At around 1,067 feet above sea level and 35% full, the Colorado River reservoir is at its lowest since the…

Russia’s vast wildfires could pump a record amount of climate-warming CO2 into the atmosphere

Russia’s vast wildfires could pump a record amount of climate-warming CO2 into the atmosphere

The Wall Street Journal reports: The smoke from the fires in Russia’s northeast is so thick it has blotted out the sun, plunging swaths of the region into darkness during the brief summer. A state of emergency has been declared in the city of Yakutsk, where freezing winter temperatures have given it the reputation of being the coldest constantly inhabited city on the planet. Residents have been told to stay indoors while volunteers and firefighters brave temperatures surpassing 100 degrees…

The complexity of the biodiversity crisis

The complexity of the biodiversity crisis

Nature reports: Scientists say it’s clear that there’s a biodiversity crisis, but there are many questions about the details. Which species will lose? Will new communities be healthy and desirable? Will the rapidly changing ecosystems be able to deal with climate change? And where should conservation actions be targeted? To find answers, scientists need better data from field sites around the world, collected at regular intervals over long periods of time. Such data don’t exist for much of the world,…

New research finds time spent among trees might help kids’ brains grow and develop

New research finds time spent among trees might help kids’ brains grow and develop

Science Alert reports: As a child grows and develops, the neurons in their brain are said to branch like trees. Being around this very type of foliage could actually help the process along. A long-term study among 3,568 students in London, between the ages of 9 and 15, has found those kids who spent more time near woodlands showed improved cognitive performance and mental health in adolescence. On the other hand, other natural environments, like grasslands or lakes and rivers,…

Space tourism is a waste

Space tourism is a waste

Gizmodo reports: Bezos’ New Shepard rocket, made by his company Blue Origin, runs on a combination of liquid oxygen and liquid hydrogen. Though neither of those emit carbon when they’re burned, producing liquid hydrogen usually does. Compressing and liquifying the oxygen for the fuel is also an energy-intensive process that, if not done using renewables, results in carbon pollution. Refining and burning these fuels isn’t just the equivalent of a tank of gas for your car. They’re not even necessarily…

Across Siberia, extreme summer heat is feeding enormous fires, thawing the permafrost

Across Siberia, extreme summer heat is feeding enormous fires, thawing the permafrost

The New York Times reports: For the third year in a row, residents of northeastern Siberia are reeling from the worst wildfires they can remember, and many are left feeling helpless, angry and alone. They endure the coldest winters outside Antarctica with little complaint. But in recent years, summer temperatures in the Russian Arctic have gone as high as 100 degrees, feeding enormous blazes that thaw what was once permanently frozen ground. Last year, wildfires scorched more than 60,000 square…

Brazil’s Amazon is now a carbon source, unprecedented study reveals

Brazil’s Amazon is now a carbon source, unprecedented study reveals

Mongabay reports: The Amazon has long done its part to balance the global carbon budget, but new evidence suggests the climate scales are tipping in the world’s largest rainforest. Now, according to a study published July 14 in Nature, the Amazon is emitting more carbon than it captures. “The Amazon is a carbon source. No doubt,” Luciana Gatti, a researcher at Brazil’s National Institute for Space Research (INPE) and lead author of the study, told Mongabay. “By now we can…

The ocean is full of tiny plastic particles – we found a way to track them with satellites

Plastic fragments washed onto Schiavonea beach in Calabria, Italy, in a 2019 storm. Alfonso Di Vincenzo/KONTROLAB /LightRocket via Getty Images By Christopher Ruf, University of Michigan Plastic is the most common type of debris floating in the world’s oceans. Waves and sunlight break much of it down into smaller particles called microplastics – fragments less than 5 millimeters across, roughly the size of a sesame seed. To understand how microplastic pollution is affecting the ocean, scientists need to know how…

EPA approved toxic chemicals for fracking a decade ago, new files show

The New York Times reports: For much of the past decade, oil companies engaged in drilling and fracking have been allowed to pump into the ground chemicals that, over time, can break down into toxic substances known as PFAS — a class of long-lasting compounds known to pose a threat to people and wildlife — according to internal documents from the Environmental Protection Agency. The E.P.A. in 2011 approved the use of these chemicals, used to ease the flow of…

How marginalized communities in the South are paying the price for ‘green energy’ in Europe

CNN reports: Andrea Macklin never turns off his TV. It’s the only way to drown out the noise from the wood mill bordering his backyard, the jackhammer sound of the plant piercing his walls and windows. The 18-wheelers carrying logs rumble by less than 100 feet from his house, all day and night, shaking it as if an earthquake has taken over this tranquil corner of North Carolina. He’s been wearing masks since long before the coronavirus pandemic, just to…
