Trial is notable for highlighting land and nature defender murders that ordinarily go unpunished

The sentencing on Thursday of seven men accused of murdering the Honduran environmentalist Berta Cáceres is only partial justice, but it should inspire anyone committed to ending the slaughter of land and nature defenders around the globe.

A court in Tegucigalpa handed down guilty verdicts on all but one of the eight accused, including two employees of the hydro-electric dam company that the indigenous Lenca woman had been campaigning against before her assassination on 2 March 2016.

Environmental campaigners against electric plant and pipeline say Samir Flores Soberanes’s murder is a ‘political crime’

A Mexican environmental activist has been murdered before a referendum on a controversial thermal-electric plant and pipeline that he opposed.

Samir Flores Soberanes, an indigenous Náhuatl, was killed in his home during the early hours of Wednesday in the town of Amilcingo in Morelos state, 80 miles south of Mexico City. He was a human rights activist, producer for a community radio station and long-time opponent of the Proyecto Integral Morelos (the integral project for Morelos) – which includes the plant and pipeline.

Nation replaces Brazil for first time in annual list of murders compiled by Global Witness

The Philippines has replaced Brazil as the most murderous country in the world for people defending their land and environment, according to research that puts a spotlight on the administration of President Rodrigo Duterte.

More than three defenders were killed across the world every week in 2018, according to the annual toll by the independent watchdog Global Witness, highlighting the continued dangers facing those who stand up to miners, loggers, farmers, poachers and other extractive industries.

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.

Economic reconstruction is a chance to speed up decarbonisation, and the pandemic has shown a different kind of politics is possible

We’re already being swamped with ideas about “reforms” needed to recover from the pandemic crisis. But the word reform is like gift wrap – a handy cover for any offering, thought-through or otherwise.

Perhaps we should ditch the word entirely, and with it the forest of feelpinions about what governments “must” do to advance an author’s previously-held ideological positioning in the post-corona world.

Welsh plan to reopen stores offers hope for UK-wide industry closed in prime sales season

Garden centres are preparing for a surge in plant and flower sales that could help salvage a catastrophic year for the horticulture industry.

The UK’s 2,000 garden centres and nurseries were forced to close in March because, unlike DIY chains such as B&Q and Homebase, they were not granted “essential” retailer status. The shutdown came at a critical time of year, with 70% of sales rung up in spring, forcing devastated growers to throw away millions of plants.

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.

Energy companies have leased 9.9m acres from the administration – and the fossil fuels extracted could equal half a year of emissions from China

The Trump administration has offered oil companies a chunk of the American west and the Gulf of Mexico that’s four times the size of California – an expansive drilling plan that threatens to entrench the industry at the expense of other outdoor jobs, while locking in enough emissions to undermine global climate policy.

Energy companies have leased 9.9m acres from the unprecedented 461m acres put up for rent by the Trump administration, according to a new analysis from the Wilderness Society.

Utah aims to reduce emissions over air quality concerns as other red states are also starting to tackle global heating

In a move to protect its ski slopes and growing economy, Utah – one of the reddest states in the nation – has just created a long-term plan to address the climate crisis.

Even as Broadway shows were shuttered and Disneyland was closed due to the Covid-19, most US national parks were open for business on Tuesday, confounding public health officials and worrying park staff who did not want to be exposed to the virus.

National parks have become a haven over the past week as the public seeks places to go during spring break. One park employee reported on Facebook that a visitor center at Big Bend national park was full on Monday with hundreds of people. Another shared a photo of shoulder to shoulder crowds at Zion national park waiting to board shuttle buses. (The park closed its shuttle bus system later in the day.)

Bank of England governor warns of financial collapse linked to climate emergency

• Top asset managers oversee $300bn fossil fuel investments
• Why are asset managers investing in fossil fuel companies?

Companies and industries that are not moving towards zero-carbon emissions will be punished by investors and go bankrupt, the governor of the Bank of England has warned.

Mark Carney also told the Guardian it was possible that the global transition needed to tackle the climate crisis could result in an abrupt financial collapse. He said the longer action to reverse emissions was delayed, the more the risk of collapse would grow.

For more than a month, coronavirus has brought cleanup of a 586-square-mile decommissioned nuclear production complex in south-eastern Washington state to a near standstill.

Most of the more than 11,000 employees at the Hanford site were sent home in late March, with only essential workers remaining to make sure the “most toxic place in America” stays safe and secure.
