Doctors are calling New Delhi's air pollution levels a medical emergency.

Until recently the battle to avert catastrophic climate change – floods, droughts, famine, mass migrations – seemed to be lost. But with the tipping point just years away, the tide is finally turning, thanks to innovations ranging from cheap renewables to lab-grown meat and electric airplanes

‘Everybody gets paralysed by bad news because they feel helpless,” says Christiana Figueres, the former UN climate chief who delivered the landmark Paris climate change agreement. “It is so in our personal lives, in our national lives and in our planetary life.”

But it is becoming increasingly clear that it does not need to be all bad news: a series of fast-moving global megatrends, spurred by trillion-dollar investments, indicates that humanity might be able to avert the worst impacts of global warming. From trends already at full steam, including renewable energy, to those just now hitting the big time, such as mass-market electric cars, to those just emerging, such as plant-based alternatives to meat, these trends show that greenhouse gas emissions can be halted.

Figures show nearly 3 million potatoes a day are wasted, at a cost of £230m a year

Nearly half of the edible fresh potatoes bought by UK householders each day are thrown away - nearly 2.7 million of them per day, and at a “staggering” annual cost of £230m, figures show.

The humble spud is the second most wasted food in the UK, behind bread, according to new official figures released on Wednesday. The new research was offered in support of a government campaign to encourage consumers to reduce their domestic food waste.

So you've installed rooftop solar – but is it performing as well as you expected? A new APVI web-based survey aims to help improve the quality of PV system components, installations and system designs.

Flinders Island's Hybrid Energy Hub is already taking the previously diesel powered Tasmanian island to levels of 80% renewables, and should manage to supply 100 per cent of demand before the year is out.

From the Apollo spacesuits to the Mars rovers, women behind the scenes have stitched vital spaceflight components.

Latest analysis from Lazard points to continuing falls in cost of wind and solar, and a growing divide between renewables and fossil fuels. And the cost of storage is falling too.

Consumers paying more on their electric bills is that’s exactly what might happen if the US Department of Energy gets its way with a recent request that bails out uneconomic coal plants.

Coal and Allied Pty Ltd will commit over $2 million as part of an enforceable undertaking entered into following a contravention of Australia’s national environment law, the Environment Protection and Biodiversity Conservation Act 1999.

Warmer and more acid seas cause huge blooms of jellyfish, but scientists are working on ways to convert them into something useful

The combination of climate change and overfishing is causing a population explosion in jellyfish. Since there are fewer fish to eat them, they appear off the British coast in vast swarms. This is a threat to nuclear power stations – because they can block the intake of cooling water – and to fish farms, where thousands get caught in the netting, sometimes killing hundreds of salmon by depriving them of oxygen.

Some species are poisonous, and so caution is required when jellyfish float next to you in the sea or are stranded on beaches. Their sting can be powerful.

Exclusive: Miner separates itself from call for environmental groups to be restricted to using 10% of funding for advocacy

BHP has said it will not support the Minerals Council’s bid to strip environmental groups of their ability to advocate for policy change.

The surprising move comes amid increasing pressure on Australia’s biggest miner to distance itself from the Minerals Council, which has taken a hardline position against any form of credible action on climate change. The government will soon table a bill aimed at limiting the ability of any charity to use donations raised from overseas on advocacy in Australia.

Overuse of antibiotics in animals is contributing to growing drug resistance in humans with serious health implications, says global health body

Farmers must be prevented from using powerful antibiotics on animals reared for food, the World Health Organisation (WHO) has warned, because of the serious risks to human health that result.

New guidelines from the global body suggest farmers should stop using any antibiotics routinely to promote growth and prevent disease in animals that are otherwise healthy, a common practice in some parts of the world, including Asia and the US. Such routine use is banned in Europe, though campaigners fear the rules are sometimes flouted.
