New Zealand’s budget needed to allocate more than small change to the climate crisis | Robert McLachlan and Paul Callister

Climate politics is a long game but people must see more positive changes to really appreciate the benefits of ending fossil fuels

The New Zealand emissions trading scheme (ETS), now in its fourteenth year of operation and much criticised for (so far) failing to cut emissions, is the centrepiece of the government’s climate action. Judging from Budget 2021, it will remain that way for years to come.

Auctioning of emissions units began in March, and 2022 will see the introduction of a falling cap on net emissions of long-lived greenhouse gases. (The precise level of the cap will be announced later in the year.)

Climate crisis behind drastic drop in Arctic wildlife populations – report

Posted on by

Native shorebirds and caribou among species at risk as survival strategies are upended

A drastic drop in caribou and shorebird populations is a reflection of the dire changes unfolding on the Arctic tundra, according to a new report from the Arctic Council.

The terrestrial Arctic spans approximately 2.7m sq miles (7m sq km), marked by extreme cold, drought, strong winds and seasonal darkness. Species living in this environment have adapted to thrive in the harsh conditions. But the climate crisis has upended such survival strategies, according to the State of the Arctic Terrestrial Biodiversity report, published by the council’s Conservation of Arctic Flora and Fauna (Caff) working group.

Climate disasters ‘caused more internal displacement than war’ in 2020

Posted on by

Refugee organisation says 30m new displacements last year were due to floods, storms or wildfires

Intense storms and flooding triggered three times more displacements than violent conflicts did last year, as the number of people internally displaced worldwide hit the highest level on record.

There were at least 55 million internally displaced people (IDPs) by the end of last year, according to figures published by the Norwegian Refugee Council’s Internal Displacement Monitoring Centre (IDMC).

Nasa leads push for electric planes in next frontier of cutting emissions

Flying on batteries presents major technological challenges but companies will be demonstrating their best efforts over the next year in California

Over the next year, at a research site on the fringes of the Mojave desert in California, Nasa will hunt for a breakthrough against one of the climate crisis’s most stubborn challenges – how to eliminate carbon pollution from aviation via a new generation of electric airplanes.

Prodded by Joe Biden’s quest to slash the US’s planet-heating emissions to net zero, Nasa is corralling companies to demonstrate improved ways to power aircraft via batteries rather than jet fuel, with the aim of phasing in electric flights for Americans within the next 15 years.

Greenland ice sheet on brink of major tipping point, says study

Posted on by

Scientists say ice equivalent to 1-2 metres of sea level rise is probably already doomed to melt

A significant part of the Greenland ice sheet is on the brink of a tipping point, after which accelerated melting would become inevitable even if global heating was halted, according to new research.

Rising temperatures caused by the climate crisis have already seen trillions of tonnes of Greenland’s ice pour into the ocean. Melting its ice sheet completely would eventually raise global sea level by 7 metres.

US climate envoy says people will not have to give up quality of life to achieve some of net zero goals

The US climate envoy, John Kerry, has said 50% of the carbon reductions needed to get to net zero will come from technologies that have not yet been invented, and said people “don’t have to give up a quality of life” in order to cut emissions.

He said Americans would “not necessarily” have to eat less meat, because of research being done into the way cattle are herded and fed in order to reduce methane emissions.

‘I’m seen as the fool’: the farmers putting trees back into the UK’s fields

Posted on by

It’s hoped a 12-year trial in Devon will persuade policymakers to back silvopasture to benefit the soil, livestock and climate

Andy Gray stands beside an enormous hill of bare red earth and smiles with a hint of mischief. This is his best field, its soils known as Crediton red land. The region was once known for producing swedes prized by Covent Garden market. Now, every six metres, planted in rows 14 metres apart, stands a tree guard shielding a young oak, aspen or alder.

“You can grow anything on it and I’m planting trees,” says Gray, a 16th-generation Devon farmer. “I’m seen as the fool on the hill. One neighbour said ‘you might as well concrete it over and build houses’. They could be right. Who knows?”

Voting at the oil giant’s annual meeting this week could see Follow This activists making trouble over emissions

Shell is braced for its largest climate rebellion this week as shareholders face the choice between backing the oil giant’s carbon-cutting plans or siding with an activist investor who is calling for tougher emissions targets.

With its annual meeting planned for Tuesday, the Anglo-Dutch company has called on its investors to vote against a shareholder resolution from campaign group Follow This in favour of its own plans to reduce its emissions to “net zero” by 2050.

Food-growing areas will see drastic changes to rainfall and temperatures if global heating continues at current rate

A third of global food production will be at risk by the end of the century if greenhouse gas emissions continue to rise at their current rate, new research suggests.

Many of the world’s most important food-growing areas will see temperatures increase and rainfall patterns alter drastically if temperatures rise by about 3.7C, the forecast increase if emissions stay high.

Exclusive: Thinning indicates profound impact of humans and could affect satellites and GPS

Humanity’s enormous emissions of greenhouse gases are shrinking the stratosphere, a new study has revealed.

The thickness of the atmospheric layer has contracted by 400 metres since the 1980s, the researchers found, and will thin by about another kilometre by 2080 without major cuts in emissions. The changes have the potential to affect satellite operations, the GPS navigation system and radio communications.

Mayor overseeing a green regeneration in city where temperatures can already surpass 40C

Like every Athens mayor, Kostas Bakoyannis is acutely aware of the illustrious heritage of one of the world’s oldest cities. After all, he says, it is busts of Pericles and his mistress Aspasia that adorn the entrance of the neoclassical town hall. From the windows of his cavernous office, he can glimpse the Parthenon through the jumble of concrete buildings and antennas.

But Bakoyannis prefers to talk about the present, not least his plans for fountains, parks and trees – antidotes to the afflictions of more modern times.

Are there too many people? All bets are off

For decades, scientists and economists have been making wagers about the outcome of human population growth. Now, more than ever, their speculations need to be taken seriously

In 2011, when the global population hit 7 billion, economist David Lam and demographer Stan Becker made a bet. Lam predicted food would get cheaper over the next decade, despite continuing population growth. Becker predicted that food prices would go up, because of the damage humans were doing to the planet, which meant that population growth would outstrip food supply. Becker won and, following his wishes, Lam has just written out a cheque for $194 to the Vermont-based nonprofit Population Media Center, which promotes population stabilisation internationally.

$194, about £140, equates to the amount by which a basket containing five food types – oils and fats, cereals, dairy, meat and sugar – and worth on average $1,000 in the decade to 2010, increased in price over the following decade, according to the UN Food and Agriculture Organization’s Food Price Index (FFPI) and allowing for inflation.

‘Decades ahead of his time’: history catches up with visionary Jimmy Carter

Posted on by

A new film rejects the popular narrative and recasts the former president, 96, as hugely prescient thinker, particularly on climate change

When I reach Jimmy Carter’s grandson by Zoom, he answers wearing a Raphael Warnock campaign T-shirt. Jason Carter is a lawyer and politician himself, mid-40s, animated and well-read, with blue eyes reminiscent of his grandfather’s. He’s just got off the phone with his 93-year-old grandmother, Rosalynn. It’s a special day; Joe Biden is on his way to the Carter house in Plains, Georgia.

“My grandfather has met nearly everyone in the world he might want to,” Jason Carter says. “Right now, he’s meeting with the president of the United States. But the person he’d say he learned the most from was Rachel Clark, an illiterate sharecropper who lived on his family’s farm.

Glacial lakes threaten millions with flooding as planet heats up

Posted on by

More than 12,000 deaths have already been attributed to glacial lake outburst floods worldwide

An increasing number of people are being threatened by flooding caused by glacial lakes bursting, scientists have warned.

As the planet warms and glaciers recede, meltwater accumulates and forms lakes, often as a result of ice or moraine acting as a dam. Since 1990, the volume, area and number of these glacial lakes has increased by 50% globally. When these lakes become too full there is a risk that they may breach or overflow, releasing huge volumes of water and causing catastrophic flooding.

Older people will have to make sacrifices in the fight against climate change or today’s children will face a future of fighting wars for water and food, the EU’s deputy chief has warned.

Frans Timmermans, vice-president of the EU commission, said that if social policy and climate policy are not combined, to share fairly the costs and benefits of creating a low-carbon economy, the world will face a backlash from people who fear losing jobs or income, stoked by populist politicians and fossil fuel interests.
