  • ‘These are human fires, not wildfires’: Dunwich reflects on the devastation

    As residents, nature wardens and experts consider the damage to the heathland and how to restore it, the climate crisis is foremost in their minds

    A local community pulling together, emergency services saving homes and caravan parks from catastrophe, and farmers and nature reserve wardens working to rapidly create fire breaks to halt a marauding fireball 40 metres high – there was plenty to praise the week after a swathe of east Suffolk burned.

    But local people were also in tears at the blackened, ruined state of more than 112 hectares (277 acres) of Dunwich Heath, mourning the devastation of a much-loved nature reserve alongside neighbouring Minsmere. The rare birds that inhabit the reserve have lost crucial habitat, while the rare invertebrate species there will have been “decimated”, according to the reserve staff.

  • Plastics contamination an ‘overlooked’ concern in food waste schemes, experts say

    Researchers find microplastics can persist in compost, leaching into agricultural soils

    Plastic contamination should be a central concern in efforts to deal with food waste, which campaigners call one of the most overlooked problems of the climate crisis, researchers have said.

    This is despite the fact that, as the chef, author and activist Max La Manna puts it, food waste management is “one of the few climate problems where everyone wins”.

  • Country diary: We’ve had fires here in the Cairngorms before. This one has changed things | Amanda Thomson

    Abernethy: It’s been a period of heartbreak and gratitude, mourning the scorched landscape and staying away from home when the smoke got too close

    Parts of the Cairngorms have been on fire for over three weeks. Many places I take for granted that I can walk to are off-limits. Huge swathes of moorland that should be purple with heather, understoreys that should be thick with blaeberries, granny pines and younger trees, are scorched black. In places, the fires has burned down into the tree root system and the peat layer, and may smoulder for weeks.

    It’s been a period of uncertainty and despair. I’ll never forget the day the wind changed direction and a huge plume of smoke rose behind the trees immediately beyond our house. We waited to see if we would be evacuated, gathered passports, important documents, medicines, and packed a bag of clothes. When residents of nearby Nethy Bridge were advised to evacuate, we stayed with a friend just outside the perimeter for the night, something I never imagined having to do.

  • ‘I couldn’t breathe’: the deadly health burden of wildfire smoke

    Scientists race to untangle complex links between exposure and mortality as fire weather grows more prevalent

    A thousand kilometres from the infernos gorging on northern Ontario’s boreal forests, Erin O’Connor watched the sky above Canada’s biggest city turn an “almost post-apocalyptic” orange as it filled with light-scattering particles of soot and ash. Stepping outside the halls of Toronto General hospital, where air filters were keeping patients safe from the worst of the fumes, she was struck by a smell so strong it felt like standing by a campfire.

    “It really hit you in the face as soon as you walked outside,” said O’Connor, who runs University Health Network’s emergency department and saw a rise in patients presenting with allergies and shortness of breath. “As the days progressed, it was like that everywhere. It seemed even inside you could smell that burning.”

  • Sadiq Khan calls on Andy Burnham to commit to climate action as pressure grows over North Sea oil

    London mayor points to ‘terrifying scenes’ this summer amid speculation Burnham may back Jackdaw and Rosebank projects

    Sadiq Khan has called on the government to commit to revamped climate action and to reduce the UK’s reliance on oil and gas, as the UK endures a summer of drought, wildfires and heatwaves.

    Writing in the Guardian, the mayor of London said that Andy Burnham’s administration must reaffirm its commitment to net zero and make clear it will continue to reduce the UK’s reliance on oil and gas “to get Britain back on track.”

  • ‘Fearless and quietly astonishing’: the dragonfly that migrates further than any other insect

    Wandering gliders are descended from some of the earliest known insects – and breed as one global population

    Revealed: the top 10 invertebrates of the year

    All hail the wandering glider, a citizen of the globe, an insect for all of us.

    Whenever we see a dragonfly zipping through the airspace and devouring tiny insects with aplomb, we can appreciate they are so timelessly effective that they have barely needed to tweak their way of life in 200m years. Odonates are directly descended from some of the earliest winged insects, known as griffin flies, which evolved around 317m years ago.

    It’s invertebrate of the year again! From August 3-12, every day we’ll be profiling one of the thousands of amazing invertebrates that our readers have nominated, and then, when you’ve got to hear about all of them, we’ll open the voting so you can choose your favourites. Don’t hesitate to get in touch with thoughts and ideas: email us at [email protected] with Invertebrate in the subject line.

  • The ornithological artist drawing 1,000 birds by hand – all for an app that wants you off your phone

    The mission of the Flock app is quietly subversive: to encourage users to ditch their screens and explore the wonderful world of birding

    On a brilliantly bright afternoon in his gallery and studio in Bolinas, a small town on the northern California coast, Keith Hansen was putting the finishing touches on a watercolor of an almost improbably flamboyant painted bunting.

    With an ultra-fine sable brush, he made a few intricate additions to the cobalt blue plumage on the bunting’s head, and, satisfied with his work, slipped the watercolor into a stout binder that every few days welcomes a new addition.

  • Avoid rare species and only take what you need: how to forage and save money on your food shopping

    While there are fears that people harvesting their food could put pressure on habitats, some ecologists suggest responsible foraging can boost conservation and biodiversity

    Angus Morton crouches behind a cricket pavilion in a London park to snip stinging nettles from an unkempt patch of greenery.

    “They’re so abundant and they’re so good,” says Morton, a regenerative gardener who pops out once a week to forage bits for dinner. “I use them in pesto, tea … I’ve even seen someone putting them in croquetas.”

    We all love bumblebees. Not only are they beautiful, busy and social, they perform pollination services that are crucial for plants, crops and human civilisation.

    Any bumblebee would be a worthy winner of invertebrate of the year but a gorgeous giant ginger bumblebee fondly known as the flying mouse? Come on!

  • Blame game as Brussels builds ‘Europe’s largest frying pan’ instead of shady square

    Architect’s vision for redevelopment of heart of EU quarter unrealised amid political wrangling and rising costs

    The redevelopment plan for Schuman Square at the heart of the EU quarter in Brussels was very ambitious. From a traffic-clogged, nondescript roundabout, it would become “an urban agora”, a greener, calmer meeting place, nothing less, said a former head of the Brussels government, than “a symbol that beats as the heart … of the European project”.

    It did not turn out that way. The result, say critics, is Europe’s largest frying pan, a concrete expanse with little greenery or shade. While the number of cars has reduced and the space is remodelled with smart grey paving, the centrepiece – a steel canopy with a green roof – was never built.
