Could bringing Neanderthals back to life save the environment? The idea is not quite science fiction | James Bradley

The Guardian - Mon, 2020-04-27 12:47

The climate emergency is unsettling our future, and erasing what we thought was certain about the past

In 2015, flooding exposed the frozen bodies of two cave lion cubs in the Yakutia region of Russia. Members of a species that vanished at the end of the last Ice Age, the pair were buried approximately 12,000 years ago when the roof of their den collapsed and trapped them in the frozen ground. In photos, their faces are so well-preserved one might almost believe they are only sleeping.

Yet despite their unusually perfect condition, the cubs are not the only such relics to have appeared in recent years. Throughout the Arctic and subarctic, animals and artefacts buried for thousands of years are reappearing, liberated from their frozen graves by the rapid warming in the region. In the Alps and elsewhere, bodies of people lost for decades in the mountains are emerging from the ice as glaciers melt. In Australia, towns submerged for generations are resurfacing as dam levels fall due to drought and heat.

Zali Steggall calls for investigation of Coalition plan to underwrite gas, hydro and coal power

The Guardian - Mon, 2020-04-27 03:30

Independent MP says scheme lacks transparency and government has no authority to introduce it

Independent MP Zali Steggall has asked the auditor general to investigate a Morrison government scheme to underwrite gas, hydro and coal power, saying it lacks transparency and citing legal advice that the Coalition had no constitutional or legislative authority to introduce it.

Announced in late 2018 after the government abandoned Malcolm Turnbull’s proposed national energy guarantee, the underwriting new generation investment (Ungi) scheme promises public support for new dispatchable power generation projects to increase competition in the electricity grid. Twelve projects have been shortlisted, including six pumped hydro plants, five gas generators and an upgrade to the Vales Point coal-fired power plant.

The first wild stork chicks to hatch in Britain for centuries are expected to emerge next month after three pairs of the huge white birds built nests in West Sussex.

Disdaining platforms constructed especially for them, the storks have created their stick nests in the heights of oak trees on the Knepp estate, the centre for a reintroduction project.

What can be better for the soul than logging the first cuckoo of spring? | Rob Penn

The Guardian - Sun, 2020-04-26 17:15

Tracking life in our garden or backyard is turning many of us into nature diarists

I heard the first cuckoo on Wednesday evening. I was outside the back door splitting logs when the song floated down from the copse on Bryn Arw, the hill behind our house in the Black Mountains. Cuckoos have been coming to the same copse for as long as we have lived here and I have always written down the date of their arrival from Africa. It is an important moment in the turning year, as the lyrics to the traditional medieval round attest: “Sumer is icumen in/ Lhude sing cuccu.”

My recordings of cuckoos have always been haphazard, though. Some years, because the weather is dreadful or I am working hard and chained to a desk, I fail to get outside. I might first hear the male’s distinctive song, which gives the bird its onomatopoeic name, days after his actual arrival.

Why Britain’s 2.5 billion paper coffee cups are an eco disaster

The Guardian - Sun, 2020-04-26 16:05

With only one in 400 cups recycled, and even those barely ‘green’, the hunt is on for an alternative

Britain gets through 2.5 billion of them every year, and the number is set to increase. But despite a growing clamour for coffee chains to make their cups more environment-friendly, the vast majority are used only once, which critics say is a considerable waste of natural resources.

One company vying to produce a truly recyclable alternative claims that the UK’s caffeine addiction is responsible for the felling of a million trees a year. An independent study it commissioned suggests that almost 1.5 billion litres of water go into making the cups the UK uses annually.

The Guardian - Sun, 2020-04-26 00:05

With Covid-19 keeping eastern Europeans away, furloughed British workers are signing up to fill seasonal vacancies – but will there be enough of them?

The first time poet Craig Santos Perez encountered a bird native to his homeland of Guam it was in a cage at San Diego zoo.

Growing up on Guam in the 1980s and 90s, Perez, a native Chamorro, had learned about the island’s lost birds at school. Children studied pictures and listened to audio recordings of their calls – but by then, the island’s forests were silent.
