Cautious optimism among experts that emissions from energy use may have peaked as net zero mission intensifies

Global efforts to slow a runaway climate catastrophe may have reached a critical milestone in the last year with the peak of global carbon emissions from energy use, according to experts.

A growing number of climate analysts believe that 2023 may be recorded as the year in which annual emissions reached a pinnacle before the global fossil fuel economy begins a terminal decline.

Disastrous events included flash flooding in Africa and wildfires in Europe and North America

The hottest year in recorded history casts doubts on humanity’s ability to deal with a climate crisis of its own making, senior scientists have said.

As historically high temperatures continued to be registered in many parts of the world in late December, the former Nasa scientist James Hansen told the Guardian that 2023 would be remembered as the moment when failures became apparent.

Conservationists say government strategy to recover England’s degraded temperate rainforest is a good start but want a target to double the area by 2050

Conservationists have praised the launch of a new government strategy to revive the remaining fragments of the vast temperate rainforests that were once “one of the jewels of Britain’s nature crown”.

Temperate rainforest, also known as Atlantic woodland or Celtic rainforest, once covered most of western Britain and Ireland. The archipelago’s wet, mild conditions are ideal for lichens, mosses and liverworts. But centuries of destruction have meant that only small, isolated pockets remain.

The best of this week’s wildlife photographs from around the world

Conservationists celebrated findings but warned that species and habitats are in overall decline in Britain

Spectacular feeding frenzies of Atlantic bluefin tuna, surging numbers of glowworms, and a record-breaking breeding season for pied flycatchers are among the British wildlife highlights of 2023.

But conservationists warned that overall wildlife continued to decline, with one in six species at risk of extinction – and that wildlife was being challenged in new ways by global heating, disease and other destructive human activities.

Escaping poverty, violence and the climate crisis are factors, but the main driver is rich societies demanding cheap labour

We seem to be living in times of unprecedented mass migration. Images of people from Africa crammed into unseaworthy boats desperately trying to cross the Mediterranean, asylum seekers crossing the Channel into Britain, and “caravans” of migrants trying to reach the Mexico-US border all seem to confirm fears that global migration is spinning out of control.

A toxic combination of poverty, inequality, violence, oppression, climate breakdown and population growth appear to be pushing growing numbers of people from Africa, Asia and Latin America to embark upon desperate journeys to reach the shores of the wealthy west.

Hein de Haas is professor of sociology at the University of Amsterdam, and the author of How Migration Really Works

Khai Cowley, 15, was killed by a suspected great white shark off Ethel beach on the Yorke Peninsula

A teenage boy killed in a shark attack off the coast of South Australia has been remembered as a talented and dearly loved member of the surfing community.

The 15-year-old, identified by friends and a family member as Khai Cowley, was mauled by a suspected great white while surfing off the remote Ethel beach on the Yorke Peninsula west of Adelaide about 1.30pm on Thursday.

Finding the elusive species in far north Queensland is a unique challenge for birders. But the search demands extraordinary enthusiasm

For 100 years, the night parrot was the undisputed mystery bird of Australian ornithology. Until the discovery and subsequent study of a tiny population in Queensland’s far west in 2013, two specimens found by the side of remote outback roads in 1990 and 2006, also in Queensland, were the only hard evidence of its continued existence.

With the parrot now present and accounted for, there remains one Australian bird that has never been photographed: the buff-breasted buttonquail.

Air quality improvements 2019-2022 from lowering vehicle emissions came even before scheme’s expansion to whole of city

More toxic air pollution has been averted by London’s ultra-low emission zones than is produced by the capital’s airports or its river and rail transport combined, according to a new analysis of the effects of the Ulez.

The report showed that improvements in air quality between 2019 and 2022 from lowering motor vehicle pollution – even before the expansion of the Ulez throughout the capital since August – rivalled the potential savings from entirely cleaning up London’s aviation or industrial and commercial heat and power generation.

When we started out, we didn’t dare dream it would lead to this: expanded rainforest, a beaver release, and rewilding at Balmoral

Sid Rawle, the 1960s peace campaigner and infamous “King of the Hippies”, once remarked that if land ownership in Britain were to be divided equally, we would each get about an acre. Surprisingly, this thought experiment would just about hold true today.

The UK measures 60m acres in total and is home to around 67 million of us. There is something rather beguiling about such extreme egalitarianism – impractical though it might be. One person, one vote, one acre. But there’s also something about it that rather helps clarify the mind should you ever find yourself, as I have done recently, trying to reform the mind-bogglingly large amounts of land owned by the British royal family.

Households will be able to drop off cables and other electrical waste in-store or have home collections, says Defra

British households will benefit from improved routes for recycling electronic goods from 2026, under government plans to have producers and retailers pay for household and in-store collections.

Consumers would be able to have electrical waste (e-waste) – from cables to toasters and power tools – collected from their homes or drop items off during a weekly shop, the Department for Environment, Food and Rural Affairs (Defra) said in a consultation published on Thursday. The ambition is for retailers, rather than the taxpayer, to pick up the tab for these new ways of disposing of defunct, often toxic products safely. The measures are due to come into force in two years’ time.

Exclusive: Developers still unwilling to put forward schemes despite change to planning rules in September

No new plans for onshore wind have been accepted in England since the government claimed it had “lifted” the de facto ban, new analysis reveals.

Renewable energy organisations warned at the time that this was likely. Despite the levelling up secretary, Michael Gove, having changed planning rules introduced in 2015 by the then prime minister, David Cameron, to stop onshore wind projects being blocked by a single objection, they still face higher barriers than every other form of infrastructure, including waste incinerators.

Monitoring what comes out of an animal is a vital part of keeping an eye on its health

I thought convincing my husband of the merits of my returning to study just as he had retired would be a tricky sell. So his enthusiasm for the idea caught me by surprise.

He helpfully suggested several interesting topics: sea turtles, dugongs and coral reefs. If it involved a boat in a warm climate, he was behind me 100%.

Successive Australian governments have kicked the can down the road when it comes to the climate crisis – and colourful activism has followed them every step of the way

Switzerland’s KlimaSeniorinnen are taking the government to the European court of human rights for doing too little to tackle the climate crisis

The women, mostly in their 70s, strode up the mountain with dogged grace. Clacking their hiking poles against sun-cooked rocks, they set sure feet on shaky stones and held hands to cross slippery streams. They knew the heat and strain were a threat to their health – they were perhaps uniquely aware of the risks – but they did not plan to let it limit their lives.

“I’m a mountain climber,” said 73-year-old Pia Hollenstein, brushing away the hand I offered to help her down a big rock. “I can manage.”

Countries less able to rebuild or who have contributed least to climate crisis suffer worst, research reveals

A list of the 20 costliest climate disasters of 2023 has revealed a “global postcode lottery stacked against the poor”, according to an analysis.

The research by the charity Christian Aid found that devastating wildfires and floods are hitting those who can least afford to rebuild, and the countries that have contributed least to the climate crisis by burning far fewer fossil fuels than wealthy nations, which have faced fewer climate disasters.

Climate Defiance, trying to make the climate crisis a top issue in 2024 election, isn’t afraid to anger ‘cowards’ and ‘criminals’

A climate protest group backed by a cadre of Hollywood film-makers is preparing to take action against “cowards” and “criminals” of all political stripes as the 2024 election approaches.

Climate Defiance, which disrupted events featuring a string of Biden administration officials this year, and targeted Darren Woods, CEO of ExxonMobil, in December, will consider protesting at events staged by both Democrats and Republicans on the campaign trail after concluding that its “very disruptive” action was bearing fruit.

International Ski Federation urged to cut emissions, while activists warn of damage through heavy use of snowmaking

After promising early dumps of snow in some areas of Europe this autumn, the pattern of recent years resumed and rain and sleet took over.

In the ski resorts of Morzine and Les Gets in the French Alps, the heavy rainfall meant that full opening of resorts was delayed until two days before Christmas, leaving the industry and the millions of tourists planning trips to stare at the sky in hope.

Platypuses have not been seen in the Torrens since the 1880s, but now the river may be healthy enough to support the species again

In May 1872, Adelaide’s doctors were surveyed about the “noxious effluvia” emanating from the River Torrens, the South Australian Advertiser reported. John Burn wrote to the paper to say he endorsed their condemnation of “the filthy state of Adelaide – a city of stenches”.

“If any of our citizens be sceptical, I would suggest his taking a stroll along King William Street on to the Morphett Street Bridge, where he might tarry a wee bit for the inhalation of the horridly pestiferous vapours there to be enjoyed,” Burn wrote.

Amid all the hysteria about ChatGPT and co, one thing is being missed: how energy-intensive the technology is

What to do when surrounded by people who are losing their minds about the Newest New Thing? Answer: reach for the Gartner Hype Cycle, an ingenious diagram that maps the progress of an emerging technology through five phases: the “technology trigger”, which is followed by a rapid rise to the “peak of inflated expectations”; this is succeeded by a rapid decline into the “trough of disillusionment”, after which begins a gentle climb up the “slope of enlightenment” – before eventually (often years or decades later) reaching the “plateau of productivity”.

Given the current hysteria about AI, I thought I’d check to see where it is on the chart. It shows that generative AI (the polite term for ChatGPT and co) has just reached the peak of inflated expectations. That squares with the fevered predictions of the tech industry (not to mention governments) that AI will be transformative and will soon be ubiquitous. This hype has given rise to much anguished fretting about its impact on employment, misinformation, politics etc, and also to a deal of anxious extrapolations about an existential risk to humanity.
