Alpine plants face extinction as melting glaciers force them higher, warns study

‘Escalator to extinction’ means aggressive species will eventually take over, threatening the entire mountain ecosystem

Alpine flowers could go extinct after glaciers disappear as more competitive species colonise terrain higher up the mountain, new research has warned.

Glaciers are retreating at historically unprecedented rates, exposing new land for plants to grow, which benefits delicate alpine species in the short term. However, these early pioneers – some of which are endemic – soon become endangered as more aggressive species take over, driving them out of their remaining habitat and decreasing overall biodiversity, according to the paper published in Frontiers in Ecology and Evolution.

Biden turns attention to climate crisis with new executive orders today – live updates

President, who has already cancelled Keystone XL pipeline, will address nation on the environment

While we’re waiting for a Covid-19 briefing, it’s worth remembering just how many people have gone through a year of pandemic without health insurance: likely at least 28.9 million.

The number of people who lacked health insurance rose through the Trump presidency, and grew by experts millions were added to the ranks of uninsured as the pandemic drove unprecedented job losses. A plurality of Americans rely on private health insurance through an employer.

WASHINGTON (AP) Fulfilling a campaign promise, President Joe Biden plans to reopen the HealthCare.gov insurance markets for a special sign-up opportunity geared to people needing coverage in the coronavirus pandemic.

Biden is expected to sign an executive order Thursday, said two people familiar with the plan, whose details were still being finalized. They spoke on the condition of anonymity because they were not authorized to discuss the pending order ahead of a formal announcement.

Hello – this is Jessica Glenza taking over from Martin Belam. Among the most high profile events happening in Washington DC today is the first Covid-19 briefing, which the Biden administration promised will be a regular feature of his administration.

At 11am ET, we’re expecting Biden’s first Covid-19 briefing. Here’s a closer look at what is expected:

(AP) - For nearly a year it was the Trump show. Now President Joe Biden is calling up the nation’s top scientists and public health experts to regularly brief the American public about the pandemic that has claimed more than 425,000 US lives.

Beginning Wednesday, administration experts will host briefings three times a week on the state of the outbreak, efforts to control it and the race to deliver vaccines and therapeutics to end it.

Humpback whales may be struggling to breed as climate crisis depletes food

Scientists say decline in calves born in past 15 years due to diminishing herring stocks in warming north Atlantic

Humpback whales could be struggling to breed due to rapid environmental change in the ocean caused by the climate crisis, a study suggests.

Scientists have confirmed a significant decline in the number of calves born to female humpbacks over the past 15 years in the Gulf of St Lawrence, Canada, an important summer feeding ground for migrating whales. They said the climate crisis has led to rapid sea temperature and sea level rise in this area of the north Atlantic, with knock-on effects for the ecosystem that include decreasing numbers of herring, a vital food source for humpback whales.

Alberta leader says Biden’s move to cancel Keystone pipeline a ‘gut punch’

Environmental groups in Canada applaud decision, but country’s western provinces left in disbelief

Joe Biden’s move to cancel a controversial pipeline project has hit Canada like “like a gut punch”, according to one political leader, and left the country to weigh the future prospects of its ailing oil and gas industry.

On 20 January, one of the US president’s first executive orders was to reverse approval of the Keystone XL pipeline, making good on a campaign promise to kill the project as part of a broader strategy to address the climate crisis.

Permanent PJs and pivoting designers: how the pandemic hit the fashion world

Our fashion editor on a year in which sweatpants soared, masks went designer, Topshop tumbled – and a pause fuelled hopes of a reset

I was on the Eurostar, somewhere between St Pancras and Paris, when a senior member of the Guardian team called and suggested that it might be a good idea for me to turn around at Gare du Nord and return to London.

It was 3 March 2020. This was not the plan. The plan had been to go to the Chanel show and report for the news pages. Instead, it was the beginning of all plans – work and otherwise – disintegrating.

As birth rates fall, animals prowl in our abandoned ‘ghost villages’

Human populations are set to decline in countries from Asia to Europe – and an unusual form of rewilding is taking place

For many years it seemed that overpopulation was the looming crisis of our age. Back in 1968, the Stanford biologists Paul and Anne Ehrlich infamously predicted that millions would soon starve to death in their bestselling, doom-saying book The Population Bomb; since then, neo-Malthusian rumblings of imminent disaster have been a continual refrain in certain sections of the environmental movement – fears that were recently given voice on David Attenborough’s documentary Life on our Planet.

At the time the Ehrlichs were publishing their dark prophecies, the world was at its peak of population growth, which at that point was increasing at a rate of 2.1% a year. Since then, the global population has ballooned from 3.5 billion to 7.67 billion.

How creating wildlife crossings can help reindeer, bears – and even crabs

Sweden’s announcement this week that it is to build a series of animal bridges is the latest in global efforts to help wildlife navigate busy roads

Every April, Sweden’s main highway comes to a periodic standstill. Hundreds of reindeer overseen by indigenous Sami herders shuffle across the asphalt on the E4 as they begin their journey west to the mountains after a winter gorging on the lichen near the city of Umeå. As Sweden’s main arterial road has become busier, the crossings have become increasingly fractious, especially if authorities do not arrive in time to close the road. Sometimes drivers try to overtake the reindeer as they cross – spooking the animals and causing long traffic jams as their Sami owners battle to regain control.

“During difficult climate conditions, these lichen lands can be extra important for the reindeer,” says Per Sandström, a landscape ecologist at the Swedish University of Agricultural Sciences who works as an intermediary between the Sami and authorities to improve the crossings.

UN warns most will live downstream of ageing large dams by 2050

Global study calls on governments to step up maintenance efforts to prevent failures, overtopping or leaks

By 2050 most people will live downstream of a large dam built in the 20th century, many of which are approaching the limits of the useful lifetime they were designed for, according to global research.

To avoid the potential for dam failures, overtopping or leaks, the dams will require increasing maintenance, and some may have to be taken out of service. Many governments have not prepared for these needs, warn the authors of a study by the United Nations University.

Electric vehicles close to ‘tipping point’ of mass adoption

Sales increase 43% globally in 2020 as plunging battery costs mean the cars will soon be the cheapest vehicles to buy

Electric vehicles are close to the “tipping point” of rapid mass adoption thanks to the plummeting cost of batteries, experts say.

Global sales rose 43% in 2020, but even faster growth is anticipated when continuing falls in battery prices bring the price of electric cars dipping below that of equivalent petrol and diesel models, even without subsidies. The latest analyses forecast that to happen some time between 2023 and 2025.

Small but mighty, Pacific states have led the charge for banning nuclear weapons | Emily Defina

A global treaty prohibiting nuclear weapons becomes international law today. But the fight to rid the world of these dismal weapons continues.

In 1995, thousands of people marched peacefully hand-in-hand through the Tahitian capital of Pape’ete. The palm-lined streets were awash with songs of protest.

On a nearby shorefront, Cook Islanders had just arrived by traditional voyaging canoe: a vaka. They were there to deliver a message of solidarity with their island neighbours, en route to the nuclear test site of Moruroa.

France passes ‘sensory heritage’ law after plight of Maurice the noisy rooster

Senators approve law to protect the noises and smells of the countryside following high-profile cases

From crowing roosters to the whiff of barnyard animals, the “sensory heritage” of France’s countryside will now be protected by law from attempts to stifle the everyday aspects of rural life from newcomers looking for peace and quiet.

French senators on Thursday gave final approval to a law proposed in the wake of several high-profile conflicts by village residents and vacationers, or recent arrivals derided as “neo-rurals”.
