Taking down the fossil fuel industry requires taking on the institutions that finance it. Even during a pandemic, this movement is gaining steam

1970 was a simpler time. (February was a simpler time too, but for a moment let’s think outside the pandemic bubble.)

Simpler because our environmental troubles could be easily seen. The air above our cities was filthy, and the water in our lakes and streams was gross. There was nothing subtle about it. In New York City, the environmental lawyer Albert Butzel described a permanently yellow horizon: “I not only saw the pollution, I wiped it off my windowsills.” Or consider the testimony of a city medical examiner: “The person who spent his life in the Adirondacks has nice pink lungs. The city dweller’s are black as coal.” You’ve probably heard of Cleveland’s Cuyahoga River catching fire, but here’s how the former New York governor Nelson Rockefeller described the Hudson south of Albany: “One great septic tank that has been rendered nearly useless for water supply, for swimming, or to support the rich fish life that once abounded there.” Everything that people say about the air and water in China and India right now was said of America’s cities then.

Planet of the Humans film has had 5m views on YouTube and has enraged renewable energy experts who are demanding an apology

Planet of the Humans is an environmental documentary that has enraged renewable energy experts and environmentalists, with some calling for its high-profile executive producer, Michael Moore, to apologise.

It was released for free less than two weeks ago, and at the time of writing had had close to 5m views on YouTube.

Revealed: records show law enforcement has called demonstrators possible ‘domestic terrorism’ threats

US law enforcement officials preparing for fresh Keystone XL pipeline protests have privately discussed tactics to stop activists “by any means” and have labeled demonstrators potential “domestic terrorism” threats, records reveal.

Internal government documents seen by the Guardian show that police and local authorities in Montana and the surrounding region have been preparing a coordinated response in the event of a new wave of protests opposing the controversial Keystone XL tar sands pipeline, which would carry crude oil from Canada to Montana, South Dakota and Nebraska.

The oil industry saw its opening and moved with breathtaking speed to take advantage of this moment

I’m going to tell you the single worst story I’ve heard in these past few horrid months, a story that combines naked greed, political influence peddling, a willingness to endanger innocent human beings, utter blindness to one of the greatest calamities in human history and a complete disregard for the next crisis aiming for our planet. I’m going to try to stay calm enough to tell it properly, but I confess it’s hard.

The background: a decade ago, beginning with indigenous activists in Canada and farmers and ranchers in the American west and midwest, opposition began to something called the Keystone XL pipeline, designed to carry filthy tar sands oil from the Canadian province of Alberta to the Gulf of Mexico. It quickly became a flashpoint for the fast-growing climate movement, especially after Nasa scientist James Hansen explained that draining those tar sands deposits would be “game over” for the climate system. And so thousands went to jail and millions rallied and eventually Barack Obama bent to that pressure and blocked the pipeline. Donald Trump, days after taking office, reversed that decision, but the pipeline has never been built, both because its builder, TC Energy, has had trouble arranging the financing and permits, and because 30,000 people have trained to do nonviolent civil disobedience to block construction. It’s been widely assumed that, should a Democrat win the White House in November, the project would finally be gone for good.

Campaigners welcomed Wednesday’s ruling as a victory for tribal rights and environmental protection

The controversial Keystone XL tar sands pipeline has been dealt a major setback, after a judge revoked a key permit issued by the US army corps of engineers without properly assessing the impact on endangered species.

In a legal challenge brought by a coalition of environmental groups, a federal judge in Montana ordered the army corps to suspend all filling and dredging activities until it conducts formal consultations compliant with the Endangered Species Act.

Conservation groups are fighting the creation of 3,500 gas wells in Wyoming that threaten a 170-mile path

The Path of the Pronghorn is a 170-mile migration route that the antelope-like creatures have traveled annually for 6,000 years. It is one of North America’s last remaining long-distance terrestrial migration corridors.

And it is at risk. This week conservation groups filed a legal petition challenging the Trump administration’s plan to allow 3,500 new gas wells in south-western Wyoming that would block the route.

Nuclear Regulatory Commission keen to allow material to be disposed of by ‘land burial’ – with potentially damaging effects

The federal agency providing oversight of the commercial nuclear sector is attempting to push through a rule change critics say could allow dangerous amounts of radioactive material to be disposed of in places like municipal landfills, with potentially serious consequences to human health and the environment.

Researchers analyzed patient data from 10 countries. The team found a correlation between low vitamin D levels and hyperactive immune systems. Vitamin D strengths innate immunity and prevents overactive immune responses. The finding could explain several mysteries, including why children are unlikely to die from COVID-19.
