Grand Tour host says impact of global heating on lake bed in Cambodia was ‘genuinely alarming’

Greta Thunberg, time traveller? Girl in photo from 1898 resembles activist

Girl in viral image looks similar to activist in both the intensity of her stare and braided hair, prompting Twitter jokes

Could Greta Thunberg be a time traveller sent from the future to save humanity from the unfolding climate crisis? A cadre of Twitter users seem to think so, after the photograph of a young Klondike goldminer bearing a striking resemblance to the Swedish activist was discovered this week.

The now viral 1898 image of three children operating a goldmine in Canada’s Yukon territory is part of a sprawling collection by the documentary photographer Eric Hegg. Near the end of the 19th century, the Swedish American captured some of the most iconic images of people hoping to make their fortunes in the rugged north.

Light pollution is key ‘bringer of insect apocalypse’

Exclusive: scientists say bug deaths can be cut by switching off unnecessary lights

Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.

Artificial light at night can affect every aspect of insects’ lives, the researchers said, from luring moths to their deaths around bulbs, to spotlighting insect prey for rats and toads, to obscuring the mating signals of fireflies.

Australia fires: record-breaking temperatures fuel bushfires across the country

Temperatures top 40C in Victoria’s north as up to 11 properties hit by fire in South Australia, while NSW and Tasmania face difficult conditions

Record-breaking spring temperatures helped spark and fan bushfires across the country on Thursday, forecasting a potentially devastating bushfire summer.

In Victoria, 100km/h winds fanned more than 60 blazes, as an unprecedented heatwave moved north to south, drawing comparisons with the “worst conditions you’d see in February or March” from the state’s emergency services minister Lisa Neville.

One-third of tropical African plant species at risk of extinction – study

Experts say new approach to classify plants’ conservation status suggests 7,000 species at risk

A third of plant species in tropical Africa are threatened with extinction, a new study suggests. Plants are crucial to many ecosystems and life in general, providing food and oxygen, as well as being the source of myriad materials and medicines. However, human activities including logging, mining and agriculture pose a major threat.

While the extinction risk of animals around the world has been well studied, the risk facing many plants remains unclear: 86% of mammal species have been assessed by the International Union for Conservation of Nature (IUCN) for its Red List, compared with only 8% of plant species. Now experts say they have come up with a rapid approach to give a preliminary classification.

To eat or not to eat: 10 of the world’s most controversial foods

From beef to cod to avocados to soya, many of our best-loved foods raise big ethical and environmental questions. What do the experts say?

Deforestation. Child labour. Pollution. Water shortages. The more we learn about the side-effects of food production, the more the act of feeding ourselves becomes fraught with anxiety. How can we be sure that certain foods are “good” or “bad” for society and the planet? As Tim Lang, professor of food policy at City University of London and the co-author of Sustainable Diets, puts it: “When you come to ‘judge’ food, you end up with an enormous list of variables, from taste to health outcomes to biodiversity.” Here are some of today’s most controversial products – and some thoughts that may help you when shopping.

Global heating supercharging Indian Ocean climate system

Indian Ocean dipole events, linked to bushfires and floods, are becoming stronger and more frequent, scientists say

Global heating is “supercharging” an increasingly dangerous climate mechanism in the Indian Ocean that has played a role in disasters this year including bushfires in Australia and floods in Africa.

Scientists and humanitarian officials say this year’s record Indian Ocean dipole, as the phenomenon is known, threatens to reappear more regularly and in a more extreme form as sea surface temperatures rise.

Amazon deforestation ‘at highest level in a decade’

Almost 10,000 sq kms lost in year to August, according to Brazilian government data

Deforestation of the Brazilian Amazon has hit the highest annual level in a decade, according to new government data which highlights the impact the president, Jair Bolsonaro, has made on the world’s biggest rainforest.

The new numbers, showing almost 10,000 sq kms were lost in the year to August, were released as emboldened farm owners scuffled with forest defenders in Altamira, the Amazonian city at the heart of the recent devastation.

Scientists develop slippery toilet coating to stop poo sticking

Spray-on surface could prevent bacteria building up and reduce household water use

The toilet brush need never leave its holder again. Scientists have created a super-slippery coating that helps usher excrement on its way without leaving traces behind.

The spray-on coating, which is slipperier than Teflon, reduces adhesion of even tenacious faeces by up to 90%, tests suggest, so far less water is needed to flush them away and leave the toilet clean.

Scientists and climate advisers condemn Tory environmental record

Party under pressure on climate crisis as Corbyn says Johnson can not be trusted

The Conservative party’s record on tackling the climate crisis was condemned by leading scientists and former government advisers on Sunday, as Labour leader Jeremy Corbyn warned that the forthcoming election was the last chance to halt the escalating emergency.

Experts accused the Conservatives of copying rightwing politicians in the US by deliberately weakening environmental protections. Meanwhile, new analysis by Labour reveals that environmental policies put forward since 2017 and opposed by the Tories would have led to emissions reductions of over 70m tonnes a year by 2030 – more than the annual emissions of Portugal.

The vanishing: Ghana’s defenders face new perils in fight against overfishing

Illegal fishing by Chinese-owned trawlers is costing the country millions – and one of the officials trying to stop it has now been missing for months

In his cramped living room in an Accra backstreet, Bernard Essien pulls out a sheet of paper – a statement signed by his elder brother Emmanuel and addressed to the Ghanaian police. Two weeks before 28-year-old Emmanuel vanished at sea, his handwritten account and accompanying video footage alleged illegal fishing by a trawler he had been working on. If the allegation was proved true, the ship’s captain faced a minimum fine of $1m.

Emmanuel Essien was a fishing observer, one of Ghana’s frontline defenders against an overfishing crisis that is among the worst in west Africa. Illegal and destructive practices by foreign-owned trawlers are draining the Ghanaian economy of an estimated £50m a year. Along its 350-mile coastline, overfishing has driven small pelagic species known as “people’s fish”, the staple diet, to the verge of collapse.
