The watershed summit in 2015 was far from perfect, but its impact so far has been significant and measurable
Ten years on from the historic Paris climate summit, which ended with the world’s first and only global agreement to curb greenhouse gas emissions, it is easy to dwell on its failures. But the successes go less remarked.
While it’s impossible to escape the emissions associated with flying, some travel methods are more carbon-intensive than others

As the Australian summer gets under way, many of us are planning holidays.
When it comes to limiting emissions associated with travel, a staycation or local holiday – by train, bus or car – remains the lowest-impact option. But overseas travel by Australians has been increasing in recent decades, with Indonesia, New Zealand, Japan, the United States and China among the top destinations, according to the Australian Bureau of Statistics.
There’s much more to do, but we should be encouraged by the progress we have made
Today marks the 10th anniversary of the Paris climate treaty, one of the landmark days in climate-action history. Attending the conference as a journalist, I watched and listened and wondered whether 194 countries could ever agree on anything at all, and the night before they did, people who I thought were more sophisticated than me assured me they couldn’t. Then they did. There are a lot of ways to tell the story of what it means and where we are now, but any version of it needs respect for the complexities, because there are a lot of latitudes between the poles of total victory and total defeat.
I had been dreading the treaty anniversary as an occasion to note that we have not done nearly enough, but in July I thought we might be able celebrate it. Because, on 23 July, the international court of justice handed down an epochal ruling that gives that treaty enforceable consequences it never had before. It declares that all nations have a legal obligation to act in response to the climate crisis, and, as Greenpeace International put it, “obligates states to regulate businesses on the harm caused by their emissions regardless of where the harm takes place. Significantly, the court found that the right to a clean, healthy and sustainable environment is fundamental for all other human rights, and that intergenerational equity should guide the interpretation of all climate obligations.” The Paris treaty was cited repeatedly as groundwork for this decision.
Research shows that the British colonial wealth extraction system still influences the region’s tourist industry
Luxury tourism in the Caribbean sells a kind of timelessness. A paradise of sun, sea and sand. But to step off the cruise ship or away from the all-inclusive resort is to see a more complex picture: a history of colonialism and a future of climate devastation. New research from the Common Wealth thinktank maps how, over the 400 years since the first English ships arrived in Barbados, empire engineered a system of wealth extraction that shapes the tourism economies of today.
Sir Hilary Beckles, Barbadian historian and chair of the Caricom Reparations Commission, describes Barbados as the birthplace of British slave society. Between 1640 and 1807, Britain transported about 387,000 enslaved west Africans to the island. Extraordinary violence, from whippings to amputations and executions, were a regular feature of their lives. On the Codrington Plantation in the mid-18th century, 43% of the enslaved died within three years of their arrival. Life expectancy at birth for an enslaved person on the island was 29 years old. This was the incalculable human cost of the transatlantic slave economy.
Fires are burning across NSW, with Tasmania also facing an emergency, while in the US, Washington state braces for floods
Bushfires have been ravaging Australia, with more than 50 burning throughout New South Wales, destroying homes and causing at least one death. Nine blazes remained out of control on Monday as flames ripped through homes and critical infrastructure. Scorching temperatures – peaking at 41C in Koolewong – combined with fierce, erratic winds to spread the fires rapidly and made them harder to control.
On Sunday night an Australian firefighter was killed after a tree fell on him while he worked on a fire near Bulahdelah, about 150 miles (250km) north of Sydney. The blaze scorched 3,500 hectares (8,600 acres) and destroyed four homes over the weekend. NSW, one of Australia’s most fire-prone regions, is particularly vulnerable because of its hot, dry climate and vast eucalyptus forests, which shed oils that become highly flammable.
Scientists say bears in southern Greenland differ genetically to those in the north, suggesting they could adjust
Changes in polar bear DNA that could help the animals adapt to warmer climates have been detected by researchers, in a study thought to be the first time a statistically significant link has been found between rising temperatures and changing DNA in a wild mammal species.
Climate breakdown is threatening the survival of polar bears. Two-thirds of them are expected to have disappeared by 2050 as their icy habitat melts and the weather becomes hotter.
An official report lays out different scenarios for the cost of transitioning away from fossil fuels to net zero by 2050
Britain’s official energy system operator has attempted to work out what achieving net zero carbon emissions will cost, with its figures showing surging spending in the coming years.
The scale and speed of the shift to a low-carbon economy, and how to fund it, are hotly debated by political parties.
Manchester Metropolitan University again wins top spot for climate and social justice in league table
More universities have severed ties with fossil fuel companies, banning them from recruitment fairs and refusing to advertise roles in the industry, according to the latest higher education league table.
The analysis found that eight more universities had signed up to end recruitment ties with the fossil fuel industry - an increase of 80% since last year. This means 18 higher education institutions, or 12% of the sector, now refuse to advertise roles with fossil fuel companies to their students.
After record flooding submerged Bor in South Sudan in 2020, the emergency response ended up turning it into a beacon of climate crisis adaptation
The three friends fill yellow jerrycans and help each other lift them on to their heads for the short walk home. Nyandong Chang lives five minutes from the water kiosk and is here up to six times a day. “It’s still hard work,” she says, “but at least nowadays water is available and clean.”
Until last year, women and children in Bor, the capital of South Sudan’s Jonglei state, faced a much tougher chore – going all the way to the filthy stretch of the White Nile that runs near the town to draw the family’s drinking, washing and cooking water and carry it back.
Cyclones like those in Indonesia, Sri Lanka and Malaysia that killed 1,750 are ‘alarming new reality’
The climate crisis supercharged the deadly storms that killed more than 1,750 people in Asia by making downpours more intense and flooding worse, scientists have reported. Monsoon rains often bring some flooding but the scientists were clear: this was “not normal”.
In Sri Lanka, some floods reached the second floor of buildings, while in Sumatra, in Indonesia, the floods were worsened by the destruction of forests, which in the past slowed rainwater running off hillsides.
Data from World Inequality Report also showed top 10% of income-earners earn more than the other 90%
Fewer than 60,000 people – 0.001% of the world’s population – control three times as much wealth as the entire bottom half of humanity, according to a report that argues global inequality has reached such extremes that urgent action has become essential.
The authoritative World Inequality Report 2026, based on data compiled by 200 researchers, also found that the top 10% of income-earners earn more than the other 90% combined, while the poorest half captures less than 10% of total global earnings.
Scientists issue urgent warning about chemicals, found to cause cancer and infertility as well as harming environment
Scientists have issued an urgent warning that some of the synthetic chemicals that help underpin the current food system are driving increased rates of cancer, neurodevelopmental conditions and infertility, while degrading the foundations of global agriculture.
The health burden from phthalates, bisphenols, pesticides and Pfas “forever chemicals” amounts to up to $2.2tn a year – roughly as much as the profits of the world’s 100 largest publicly listed companies, according to the report published on Wednesday.
Kolahoi is one of many glaciers whose decline is disrupting whole ecosystems – water, wildlife and human life that it has supported for centuries
From the slopes above Pahalgam, the Kolahoi glacier is visible as a thinning, rumpled ribbon of ice stretching across the western Himalayas. Once a vast white artery feeding rivers, fields and forests, it is now retreating steadily, leaving bare rock, crevassed ice and newly exposed alpine meadows.
The glacier’s meltwater has sustained paddy fields, apple orchards, saffron fields and grazing pastures for centuries. Now, as its ice diminishes, the entire web of life it supported is shifting.
