Needing no soil or sun, an underground farm in Liverpool challenges traditional methods

Beautifully arranged rows of bok choi, parsley, tarragon and basil alongside dozens of variety of lettuce grow together in harmony under the pink glow of an LED light in a former sugar factory.

Water infused with nutrients trickles on to the green towers, keeping the rosettes hydrated and fed. This is a technically advanced indoor vertical farm buried deep in a basement at a former Tate & Lyle warehouse and now the Liverpool Life Sciences UTC.

Event may need to be played at night or in shoulder season as climate crisis exposes players and fans to unprecedented levels of extreme heat

The Melbourne Boxing Day Test may have to be played at night or moved away from Christmas to November or March as the number of extreme heat days rises over coming decades, a new report says.

The analysis by the Monash Climate Change Communication Research Hub says the climate crisis is already disrupting Australian cricket, citing the cancellation of club matches on hot days and the abandonment of a Big Bash game in Canberra after bushfire smoke reduced air quality and visibility.

With stocks rebounding, regulators have reopened a groundfish habitat off the west coast – with environmentalists’ support

A rare environmental success story is unfolding in waters off the US west coast.

After years of fear and uncertainty, bottom trawler fishermen – those who use nets to catch rockfish, bocaccio, sole, Pacific Ocean perch and other deep-dwelling fish – are making a comeback here, reinventing themselves as a sustainable industry less than two decades after authorities closed huge stretches of the Pacific Ocean because of the species’ depletion.

The creatures have thrived for 450 million years and possess some remarkable characteristics

The common starfish, Asterias rubens, is inedible, useless as bait and has zero commercial value. Such is the damning verdict of shoreline anglers on a species that has been thriving for 450 million years. After winter storms they are often seen stranded on beaches but otherwise in summer are found by delighted children in rock pools around British coasts. Also known as sea stars because of their five arms, specimens are usually orange or brown and grow to 10 to 30cm (11.8 inches) across, although sometimes larger depending on the food supply.

They are strange creatures, spiny on top and able to move around on small bumpy tubes on their underside. They have cells that “smell” prey and detect light. Chop them up and each piece will regrow into new starfish provided a part of the central core remains in each piece. But perhaps their most remarkable feature is the ability to turn their stomachs inside out through the mouth to absorb prey and then suck the stomach back into the body.

Kate Barker on a blueprint to boost flood resilience across the country, Roger Abbott on a simple fact about rivers that seems to be consistently ignored and Pete Dorey on residents’ suffering

The call by leaders from the north and Midlands for an overhaul of how flood defence activity is funded and organised (Report, 23 December) will strike a chord with many across the country. Currently, 1m homes in the UK have a higher than 1% chance of flooding in any given year, and recent months have shown the devastating impact of flooding on households and businesses.

Looking beyond what the effective emergency response is, we must do more to plan how to adapt to climate change and not continue with the current cycle of reactive funding that typically follows floods.

Mini, Vauxhall Corsa and Fiat 5oo will join rapidly expanding European EV market

Europe’s carmakers are gearing up to make 2020 the year of the electric car, according to automotive analysts, with a wave of new models launching as the world’s biggest manufacturers scramble to lower the carbon dioxide emissions of their products.

Previous electric models have mostly been targeted at niche markets, but 2020 will see the launch of flagship electric models with familiar names, such as the Mini, the Vauxhall Corsa and the Fiat 500.

A barge carrying 2,000 litres of diesel has sunk at a dock on San Cristóbal Island in the Galápagos archipelago. The incident occurred as workers attempted to load a container on a barge with the crane and both somehow tipped, destabilising the vessel which turned on its side. Barge workers began to jump into the water to escape the sinking vessel. A clean-up operation has begun and environmental impact is unclear
