the hard stuff

ON ONE side of the world, fires have turned Australia’s skies black and menaced the country’s largest city, Sydney (see page 7). On the other, floods in England have killed a woman and triggered emergency evacuations. While UK prime minister Boris Johnson said severe flooding was “almost certainly” happening more often because of climate change, Australian prime minister Scott Morrison refused to answer questions on global warming. Despite increasing calls from citizens for action, political will on climate change is still uneven. One bright spot came last week, when New Zealand became the latest country to pass a law to reduce carbon emissions to net zero by 2050. Such goals are vital, not just because they are what the science demands for us to avoid catastrophic warming, but also because they draw…

australian emergency

WILDFIRES are ravaging Australia’s eastern coast. As New Scientist went to press, at least three people had died, 100 people had been injured and 150 homes and buildings had been destroyed by the blazes. The situation looked set to worsen as hot and dry winds pick up in strength. A week-long state of emergency has been declared in New South Wales, giving emergency services the power to shut off electricity and evacuate people from their homes. Some 600 schools have been shut down over safety concerns. David Elliott, the New South Wales minister for police and emergency services, said the country faced what “could be the most dangerous bushfire week this nation has ever seen”. The fires come after Australia’s hottest summer on record, and an unusually hot and dry winter. “When…

could fracking yet resume in england?

JUST days after the UK’s Conservative government halted fracking for gas in England, the civil service put out a document stating that “future applications will be considered on their… merits”. That document, dated 4 November, was obtained by the i newspaper. In it, the government doesn’t rule out accepting new applications for fracking operations. A Conservative party spokesperson told the i that the ban doesn’t technically prevent applications, but it does mean they will be refused. The opposition Labour party has called the ban an election stunt.…

vaping nearly killed uk boy, say doctors

A TEENAGER in the UK almost died from respiratory failure linked to e-cigarettes, according to medical staff. Ewan Fisher had been vaping for four to five months before he was taken ill aged 16. He had developed hypersensitivity pneumonitis – an allergic reaction to something breathed in which results in inflammation of lung tissue (Archives of Disease in Childhood, doi.org/dd2f). Jayesh Mahendra Bhatt at Nottingham University Hospitals NHS Trust, who treated Ewan, said: “The evidence… showed that [vaping] was to blame.”…

the largest ever ape

STANDING at least 2.5 metres tall, Gigantopithecus lived in the forests of South-East Asia between 2 million and 300,000 years ago. It was larger than any living great ape, but all we have found of it so far are teeth and fragments from jawbones (see picture), so we know little about its appearance or behaviour. Now we have been able to glimpse its family tree, which suggests it split from orangutan-like cousins around 11 million years ago. To create the family tree, Frido Welker at the University of Copenhagen in Denmark and his colleagues studied a 1.9-million-year-old Gigantopithecus tooth discovered in southern China. The climate in this region is subtropical, with an average temperature of around 20°C. In such warm and wet conditions, DNA soon breaks down, so it isn’t possible to read…
