Collapsing ice shelves will further accelerate global sea level rise

Very soon, a large portion of an ice shelf in Antarctica will break off and collapse into the ocean. The name of the ice shelf is Larsen C; it is a major extension from of the West Antarctic ice sheet, and its health has implications for other ice in the region, and sea levels globally.

How do we know a portion is going to collapse? Well, scientists have been watching a major rift (crack) that has grown in the past few years, carving out a section of floating ice nearly the size of Delaware. The speed of the crack has increased dramatically in the past few months, and it is nearly cracked through.

Exclusive: Walking or cycling to school is better for children’s health as cars are ‘boxes collecting toxic gases’ says David King

• Opinion: Smoking in cars is banned. But children still inhale toxic fumes in backseats

Children are at risk of dangerous levels of air pollution in cars because exposure to toxic air is often far higher inside than outside vehicles, a former government chief scientific adviser has warned.

Prof Sir David King, writing for the Guardian, says walking or cycling to school would be much better for children’s health. The warning comes as the UK government faces a third legal defeat for failing to tackle the country’s illegal levels of air pollution. Air pollution is known to damage children’s developing lungs but recent research also indicates it harms children’s ability to learn at school and may damage their DNA.

Epping Forest Yellow rattle steals nutrients from grasses, releasing butterfly-friendly plants from the oppression of shade

The poet John Clare crossed here 180 years ago seeking the “furze and clouds” of Buckhurst Hill, but I’m happy to linger on Whitehall Plain amid its dazzling drifts of buttercups. Natural grasslands are now rare in southern England – 98% of them were destroyed in the 50 years after 1945 – and too often seen as easily replicated green space. Not here in Epping Forest, though. Beneath its surface gloss of buttercups, this old pasture, which straddles London’s boundary with Essex, is complex and dynamic.

A tree planting project transforms a Bega Valley landscape; a young couple grinds out a living off just eight hectares; we turn unwanted fruit and veg into edible powder; and meet four-year-old dog trialler Alyssa Brown.

The short answer is, not a lot. Finkel promises savings of $92 a year by 2030, but most customer bills are going to jump $300 a year next month. Nothing much will change until utilities can match the cost of new technologies, rather than hiding behind regulatory barriers.

Dr Alejandro Hernández Cárdenas has developed a new technique to help identify corpses.

Elon Musk says all Tesla EV supercharging stations are being switched to solar and battery storage – "almost all" will disconnect from grid.

Frydenberg and Turnbull are trying to convince far right that coal will be OK under Clean Energy Target. But the reality is that wind and solar are cheaper, so any serious push to climate targets will spell doom for coal generation.

The earliest known script was a tool developed to help run the economy.

Di Natale says the Finkel report gets Australia no where near the temperature target commitment made in Paris and provides a long term lifeline to coal and gas.

DARTMOOR: The best way to see the country of the high moorland is, I am now convinced, from horseback. A docile eight-year-old mare carried me for three hours over Holne Moor and along the thickly wooded valley of the Dart and provided a morning of great delight. Early in the ride, descending from the moor to the river valley, we started a buzzard from the heather. The bird rose into the air and crossed the valley in gracious soaring and gliding. The silhouette of the buzzard is particularly appropriate to its function as a bird of prey – a menacing dark brown shape with broad wings upturned at the tips. Its loud mewing call which echoed in the confined valley was an eerie warning to small creatures on the ground.

Engineers call them nano-particles, and close to congested roads and busy airports, we inhale them in astonishing numbers

In 1996, the Scottish scientist Anthony Seaton put forward a new theory about the health problems from modern air pollution. Throughout our evolution, we have always lived with dusts, but Seaton suggested that the problems from modern air pollution were due to the sheer number of tiny pollution particles that we are now exposed to.

Use of wrasse to combat parasite threatens natural stocks, say experts

Salmon farmers have been accused of playing dirty by using fish caught in the wild to clean lice from Scottish fish farms. Marine conservation experts say that shipping tonnes of English-caught wrasse a year – to tackle lice infestations in salmon pens north of the border – is endangering natural stocks. English anglers have also warned wrasse is becoming harder and harder to find in local waters.

However, salmon farmers have rejected the charge. They say the use of wrasse as a “cleaner” fish is part of a long-term plan to replace chemicals – which are currently administered to pens to control lice infestations – with sustainable, biological controls.

South Uist The dominant hue will change gradually, as first one then another wildflower species comes to the fore on land left to lie fallow

The continuation of traditional crofting methods ensures that the island’s machair is still celebrated for the spectacular profusion of wildflowers that occurs in the summer. Yellows, whites, purples and blues are all present, though the dominant hue will change gradually, as first one then another species comes to the fore on the land left to lie fallow. But where, after their period of rest, different areas are put back under cultivation, there are other changes in colour.

This spring the grassland down at the end of the track that reaches the sea came under the plough, its green replaced by an expanse of pale open ground. Stretches of machair ready for planting are nothing like prepared fields seen elsewhere in Britain.
