Blackwater, Norfolk Pollinated flowers means more plants next year – and more thistles means more bees

After explaining to a visitor the lengths to which I go to encourage marsh and spear thistles on my fen, I was amused to hear her describe the troubles she takes to keep them from her garden. I know they’re prickly customers, but why do people dislike them?

What I cherish most is the sheer architectural grandeur of the summer plant. Each fully open flowerhead has a kind of declarative beauty – a blend of spine-fringed awkwardness and inner sensuous velvet. No wonder nations have hitched their wagons to the thistle’s star-like bloom. Even in autumn, when they are desiccated and devoid of seed floss, and possibly enwrapped in old spider’s web, they retain an aura of dignity.

Resources minister tells Q&A audience Adani’s Queensland mine would not stop Australia meeting its Paris climate change commitments because the coal is burned overseas

The federal minister Matthew Canavan has defended government support for Adani’s Carmichael mine by saying coal burned overseas will not stop Australia meeting its Paris climate commitments.

Canavan also denied the prime minister, Malcolm Turnbull, had politicised the defence force by using a backdrop of masked soldiers to announce plans to enable military handling of domestic terrorist threats, telling the ABC’s Q&A program it wasn’t a “campaign announcement”.

An ambush by local rebel forces led to five deaths in the Okapi Wildlife Reserve, while another ranger died in Virunga

Four Congolese park rangers and one porter have been killed in an ambush in the eastern Democratic Republic of the Congo.

A large group of journalists and park rangers were attacked on Friday 14 July in the Okapi Wildlife Reserve by an armed local rebel group. It is believed that the journalists – one from the US, two Dutch, and one Congolese – were covering a story about the work of the rangers in the forest.

We produce 300m tonnes of plastic a year – 5m tonnes of which ends up in the oceans. How easy is it to ditch the excess packaging and learn to love shampoo in solid bars?

It’s in shampoo bottles, toothbrushes, clothes and biros. It’s even in teabags. Plastic is everywhere.

In some cases this brings clear benefits – plastic has brought advances including domestic pipes, composite materials for lighter aircraft and wind-turbines, as well as blood bags – but, for consumers, it is largely cosmetic: a cheap signifier of hygiene and a mainstay of convenience.

En Guatemala está uno de los mayores depósitos de plata del mundo; a sus dueños canadienses les proporciona millones de dólares, pero para los campesinos locales pone en peligro sus tierras y, a veces, sus vidas

Lean esta historia en inglés

A grandes profundidades, enterrado en las exuberantes colinas del sur de Guatemala, se encuentra un verdadero tesoro: toneladas de plata que forman uno de los mayores depósitos del mundo.

Sin embargo, lo verdaderamente peligroso sucede en la superficie. En una carretera polvorienta, aproximadamente 50 campesinos rezan en círculo, una especie de barricada para que no pasen los camiones que se dirigen a la mina. La policía ya los ha dispersado por la fuerza con gases lacrimógenos. Ahora tienen miedo de que llegue el ejército.

Stop obsessing with how personally green you live – and start collectively taking on corporate power

Would you advise someone to flap towels in a burning house? To bring a flyswatter to a gunfight? Yet the counsel we hear on climate change could scarcely be more out of sync with the nature of the crisis.

The email in my inbox last week offered thirty suggestions to green my office space: use reusable pens, redecorate with light colours, stop using the elevator.

Each shed here contains 42,000 chickens. The conditions are all in line with government regulations, but there are around 17 birds per square metre

In a valley in rural Herefordshire, near the village of Kington, four industrial sheds lie partly covered in trees, with an apple orchard on the approach. From the top of the hill there is no odour, but nearer to the sheds – 100m long by 20m wide, with 42,000 chickens in each – the sweetish, sickly smell is overpowering. The broiler chickens, grown for meat, are stocked at around 17 birds per square metre. Birds are packed as far as the eye can see within the buildings, making it impossible to see the floor.

Whether you are concerned about the welfare of animals or the businesses of small farmers, we’d like to hear from you

The rise in mega farms, which can house thousands of animals indoors, has caused concern among farmers and residents.

Key issues in intensive livestock farming include the lack of accountability, noise and smell as well as the way the farms are industrialising and transforming the countryside. Whether you’re involved in the planning process, work at a mega farm, or live near one we’d like to hear how you have been affected.

Exclusive: US-style intensive factory farming of poultry, pigs and cattle is sweeping across the British countryside – raising concerns over animal cruelty

• How have you been affected?
  

Nearly every county in England has at least one industrial-scale livestock farm, with close to 800 US-style mega farms operating across the UK, new research reveals.

The increase in mega farms – which critics describe as “cruel and unnecessary” – is part of a 26% rise in intensive factory farming in six years, a shift that is transforming the British countryside.

I propose that people take indefensible positions like climate denial and Trump support simply out of fear

This story picks up where an earlier post left off a few weeks ago. Then, I discussed some of the political realities associated with inaction on climate change. In that post, I said I would revisit the question of why so many people deny the evidence of a changing climate. Now is the time for that discussion.

What continually befuddles people who work on climate change is the vehement and indefensible denial of evidence by a small segment of the population. I give many public talks on climate change, including radio and television interviews and public lectures. Nearly every event has a few people who, no matter what the evidence, stay in a state of denial. By listening to denialist arguments, I find they fall into a few broad categories. Some of them are just plain false. Examples in this category are ones like:

The Havasupai are attempting to fight back against the operation of a uranium mine that they say could contaminate their sole water source

Ed Tilousi knelt down next to the crystal-clear turquoise creek. The only sounds were the gurgling of the current and the sawing of cicadas in a pecan nut tree as the hot sun made the red rock canyon walls towering above him glow.

Downstream, the creek becomes a 100ft-high waterfall, tumbling into a brilliant blue pool then making more cascades before it empties into the Colorado river running through the Grand Canyon.

Sandsend, North Yorkshire It’s not a jellyfish but a ctenophore, one of a group thought to be more than 500m years old

Close to dead calm on the Yorkshire hem of the North Sea today. The waves are barely 10cm high and the water is so clear that, standing knee-deep between each half-hearted surge, I can see sand grains shifting on the bottom.

A rare sighting of a red-backed shrike, notorious for its habit of impaling its victims in a grisly larder

The first sign of autumn appeared the moment we arrived. A spotted redshank, resplendent in its dusky breeding plumage, stopping off on my Somerset coastal patch as it headed south from its Arctic nesting grounds.

But the start of July is far too early for any songbird migrants. So along with my companion Daniel, whom I met on our very first day at grammar school, almost half a century ago, I simply enjoyed the fine weather, and its associated marbled white and meadow brown butterflies.

A Victorian garden sensation has become a sensational invasive nuisance. Contact with its toxic sap causes burns and blisters that can take months to heal

It’s a monster towering up to 20ft tall, leaves spreading out like giant hands and flowers arranged in clusters the size of dinner plates. This is the giant hogweed, and the tabloids have been running alarming headlines recently, claiming an explosion in numbers of “Britain’s most dangerous plant” is creating havoc as it spreads in the hot weather this summer.

In reality, the plant only spreads by seed, each plant producing up to 50,000 seeds released from late August onwards and cast into the wind or water. But the giant hogweed is undoubtedly a dangerous plant, armed with highly toxic sap and just brushing past it with bare skin is enough to cause painful skin burns, which blister when exposed to ultraviolet rays in daylight, and can take months to heal. Even years afterwards the skin remains sensitive to sunlight.

Inside the Lancashire protest camp aiming to disrupt new Cuadrilla wells with direct action tactics

It is a battle that has gone on for years, pitting tireless local residents and environmentalists against a major gas exploration company hoping to get rich – and solve a future energy crisis – by fracking under the Fylde coast.

Last October the government overruled Lancashire county council and gave Cuadrilla the green light to begin drilling, but anti-fracking activists have refused to give up their fight.

The UK’s first geothermal plant could come online as soon as 2020 – research suggests the technology could one day generate a fifth of the nation’s power

A pioneering project to produce power from hot rocks several kilometres under the ground in Cornwall will begin drilling early next year, if a multimillion-pound fundraising drive succeeds.

Abundance, a crowdfunding platform overseen by the main City regulator, will this week launch a bond to raise £5m for the UK’s first commercial geothermal power station, located near Redruth.

Around Yellowstone national park, mining companies anticipate the end of the Obama-era moratorium, but local businesses are fighting back

• Help support the Guardian’s coverage of the government’s public land sell-off

Bruce Gordon’s Cessna Centurion floats off the runway south of Livingston, Montana, quickly escaping the confines of Paradise Valley, walled on both sides by the Absaroka and Gallatin mountain ranges. Snaking through the alfalfa fields, cottonwood thickets and ranches below, the Yellowstone river is still surging with late spring snowmelt.

As soon as we crest the ridges, the whole of Yellowstone national park is visible to the south, with Grand Teton towering on the far horizon. Places that would take hours to drive between – because of impassable mountains and roadless wilderness – are revealed to be only a handful of miles apart. The nearly 1 million acres of the Absaroka-Beartooth Wilderness is spread out to the east, teeming with unseen elk herds, mountain lions, and grizzly bears. Gordon, who runs the nonprofit EcoFlight, based in Aspen, Colorado, pilots flights like this one to help people understand conservation issues with a view from above. “We’re coming up on Emigrant Gulch now,” Joe Josephson, sitting in the co-pilot’s seat, says over the intercom as we fly over the green-roofed buildings of Chico Hot Springs resort, skirting the conical 10,915ft Emigrant Peak. Josephson, an avid mountaineer who recently summited Emigrant Peak to celebrate his 50th birthday, is the Montana Conservation Associate for the Greater Yellowstone Coalition, a nonprofit devoted to defending the 20 million-acre Yellowstone ecosystem from degradation.

Britain is an international leader in animal welfare and now, fortunately, the message is beginning to spread – importantly to China

Animal welfare is one of the UK’s most successful exports. When the late Peter Roberts, a Hampshire dairy farmer, founded the charity Compassion in World Farming (ciwf.org.uk) 50 years ago, he rightly feared that industrialised farming would wreak havoc on animals and the planet. Even he couldn’t have envisaged today’s numbers: 70 billion animals are reared globally for meat, milk and eggs each year and two thirds of farm animals are reared intensively. We call it factory farming. The mission of CIWF is to bring it to a halt.

The concept of animal welfare didn’t have an equivalent in Mandarin or Cantonese.

Simultaneous harvest failures in key regions would bring global famine, says the Met Office

Governments may be seriously underestimating the risks of crop disasters occurring in major farming regions around the world, a study by British researchers has found.

The newly published research, by Met Office scientists, used advanced climate modelling to show that extreme weather events could devastate food production if they occurred in several key areas at the same time. Such an outcome could trigger widespread famine.
