Switching 50km/h speed limits to 30km/h would protect cyclists while barely affecting commutes, research finds

Posted on by

One expert says a cyclist hit by a car travelling 50km/h has about a one-in-ten chance of surviving, while at 30km/h it was a nine-in-ten chance

Reducing residential speed limits from 50km/h to 30 km/h would protect cyclists from danger and make riding less stressful while not causing traffic delays for cars, according to new research.

Researchers from RMIT University rated traffic stress levels for every road in greater Melbourne and modelled the effect of lower speed limits on bicycle and car travel.

Carmakers chose to cheat to sell cars rather than comply with emissions law, ‘dieselgate’ trial told

Posted on by

Mercedes, Ford, Renault, Nissan and Peugeot/Citroën face group action in which damages could exceed £6bn

Car manufacturers decided they would rather cheat to prioritise “customer convenience” and sell cars than comply with the law on deadly pollutants, the first day of the largest group action trial in English legal history has been told.

More than a decade after the original “dieselgate” scandal broke, lawyers representing 1.6 million diesel car owners in the UK argue that manufacturers deliberately installed software to rig emissions tests.

New Zealand accused of ‘full-blown climate denial’ over cuts to methane reduction targets

Posted on by

Farmers praised the move, but scientists and opposition parties criticised it as ‘weak’ and ‘unambitious’

Environmental campaigners have accused New Zealand’s government of “full-blown climate denial” after it slashed targets for reducing emissions of methane, a potent greenhouse gas that contributes to global warming.

New Zealand’s right-leaning coalition government outlined plans on Sunday to reduce methane emissions by between 14 and 24% by 2050, compared to 2017 levels.

A 2% blend of low-carbon gas injected into gas grid to fuel Brigg power station in North Lincolnshire is a UK first

Energy companies have injected green hydrogen into Britain’s gas grid and used the low-carbon gas to generate electricity, in a landmark development for the UK’s climate ambitions.

For the first time in the UK, a 2% blend of green hydrogen was injected into the gas grid and blended with traditional gas to fuel the Brigg power station in North Lincolnshire which generated electricity for the power system.

Planet’s first catastrophic climate tipping point reached, report says, with coral reefs facing ‘widespread dieback’

Posted on by

Unless global heating is reduced to 1.2C ‘as fast as possible’, warm water coral reefs will not remain ‘at any meaningful scale’, a report by 160 scientists from 23 countries warns

The earth has reached its first catastrophic tipping point linked to greenhouse gas emissions, with warm water coral reefs now facing a long-term decline and risking the livelihoods of hundreds of millions of people, according to a new report.

The report from scientists and conservationists warns the world is also “on the brink” of reaching other tipping points, including the dieback of the Amazon, the collapse of major ocean currents and the loss of ice sheets.

Australia’s household energy bills will halve by 2050, modelling suggests

Posted on by

Grattan Institute report argues fall in costs will provide federal government room for more action on climate

Australian household energy bills will halve by 2050 as solar panels, batteries and electric cars and appliances become the norm, reducing pressure on the federal government over living costs and creating room for more climate action, a thinktank study suggests.

Modelling by the Grattan Institute finds that cutting greenhouse gas emissions from electricity generation in line with the goal of reaching net zero emissions by 2050 will cut average household energy costs from about $5,800 today to about $3,000.

Number of endangered butterfly species also surging amid habitat destruction and global heating, finds study

The number of wild bee species in Europe at risk of extinction has more than doubled over the past decade, while the number of endangered butterfly species has almost doubled.

The jeopardy facing crucial pollinators was revealed by scientific studies for the International Union for Conservation of Nature (IUCN) red list of threatened species, which found that at least 172 bee species out of 1,928 were at risk of extinction in Europe.

Crocodile made famous by Steve Irwin ‘wrongfully arrested’ and should be returned to wild, traditional owners say

Exclusive: ‘Old Faithful’ was captured after Queensland authorities deemed him ‘a problem crocodile’, but Rinyirru Aboriginal Corporation says the government is mistaken

Traditional owners have called on the Queensland environment minister to return an iconic saltwater crocodile to the wild, arguing his capture was a “wrongful arrest” – but that his case could prove “a landmark” in redefining consultation with First Nations people and the management of crocodiles.

Rinyirru (Lakefield) Aboriginal Corporation chair, Alwyn Lyall, wrote to the environment minister, Andrew Powell, on Friday saying the removal of a crocodile longer than 4 metres, known as “Old Faithful”, from Rinyirru – or Lakefield national park – last month was based on a “flawed and outdated” test of his behaviour and highlighted “a bigger problem in how crocodiles are managed”.

Grisly recording reveals bat catching, killing and eating robin mid-flight

Before the Spanish study, some scientists had been sceptical about the mammals attacking migratory birds

Bats are generally viewed as harmless, if spooky, creatures of the night. But scientists have revealed a more savage side, after witnessing a greater noctule bat – Europe’s largest bat species – hunting, killing and devouring a robin mid-flight.

The grisly recording reveals the bat as a formidable predator, climbing to 1.2km (4,000ft) before embarking on a breakneck-speed dive in pursuit of its prey. On capture, the bat delivered a lethal bite and subsequent chewing sounds, recorded between echolocation calls, indicated that the bat consumed the bird continuously during flight for 23 minutes without losing altitude.
