Greek capital is first in Europe to create role, which will involve finding new ways to cool the city

Athens has appointed a chief heat officer to protect people from soaring temperatures and try to find ways to adapt the city to the heatwaves and extreme weather that are striking the capital more frequently as the result of the climate emergency.

The appointment, made on Friday by the mayor of Athens, Kostas Bakoyannis, is the first in Europe and believed to be only the second in the world, after Miami-Dade county in Florida appointed a chief heat officer earlier this year.

• California official: ‘Water stealing has never been more severe’

• Water taken from hydrants, homes, rivers and wells

Extreme and prolonged drought in the American west is prompting water thieves to tap into other people’s scarce supplies.

More than 12bn gallons of water have been stolen in California in the past eight years, according to state officials, but the issue has been further exacerbated by the ongoing drought and recent searing early summer heatwaves.

Researchers suggest net increase would mostly occur in renewables sector, with decline in fossil fuels

If some politicians are to be believed, taking sweeping action to meet the goals of the Paris climate agreement would be calamitous for jobs in the energy sector. But a study suggests that honouring the global climate target would, in fact, increase net jobs by about 8 million by 2050.

The study – in which researchers created a global dataset of the footprint of energy jobs in 50 countries including major fossil fuel-producing economies – found that currently an estimated 18 million people work in the energy industries, which is likely to increase to 26 million if climate targets are met.

Unesco says ‘the facts are the facts and the science is the science’ after its recommendation is ignored

The Great Barrier Reef will not be placed on a list of world heritage sites “in danger” after a global lobbying effort from Australia against the proposed listing.

The 21-country World Heritage Committee on Friday ignored a scientific assessment from the UN’s science and culture organisation, Unesco, that the reef was clearly in danger from climate change and so should be placed on the list.

From fossil fuels to carbon offsetting, the British government must practise what it preaches if it is to inspire others to step up

This summer alone has seen scorching heat domes smother parts of the US and Canada with record temperatures, and blistering heatwaves sweep across Pakistan. Torrential rain has caused devastating floods in China, as well as India, Germany, Belgium and Austria. And while fires are raging in Siberia, Madagascar is experiencing the world’s first famine caused solely by the climate crisis. Even here in the UK, the first extreme heat warnings were issued earlier this week.

New extreme-weather events linked to the climate crisis have become rolling news. Their destruction and death tolls are a daily reminder that the UK-hosted Cop26 this autumn isn’t just the most important climate conference ever held, but the most important international summit of all time.

With 100 days to go to crucial UN crisis summit in Glasgow, PM is accused of lack of leadership

Protesters will fill London’s Parliament Square on Friday morning, calling on the prime minister, Boris Johnson, to make the climate crisis his top priority, as the UK prepares to host UN talks that will determine whether the world tips into environmental catastrophe this decade.

Rescuers pulled inflatable boats in flood waters gushing through streets of Turkey's Black Sea district of Arhavi on Thursday to bring those stranded to safety.

Footage released by the country's interior ministry showed distressed residents being evacuated from flooded homes. Access to dozens of villages in Arhavi were blocked and rescue efforts were under way - with officials saying 200 people had been evacuated.

Floods are common along Turkey's Black Sea coastal region at this time of year. Last week, at least six people were killed and two others went missing in flood waters in Black Sea province of Rize

Sulphur-crested cockatoos’ ability to pry open bins has spread across 44 suburbs in only two years

Sulphur-crested cockatoos are learning from each other to open wheelie bins in order to scavenge for food and the behaviour is rapidly catching on across Sydney, according to new research.

With help from the public, Australian and German ecologists have documented cockatoos learning the bin-diving behaviour through social interactions, with reported sightings of the behaviour growing across Sydney in recent years.

Sulphur-crested cockatoos are learning to pry open bins, with researchers finding the new skill has caught on in 44 Sydney suburbs in just two years. With help from the public, Australian and German ecologists have documented cockatoos learning the bin-diving behaviour through social interactions. The research, published in the journal Science, also found differences in the cockatoos’ bin-opening technique between different suburbs, arising from 'local subcultures'.

Government urged to speed up transition to green energy as Australia’s biggest market shifts away from LNG and coal

A Japanese pledge to wind down gas and coal-fired electricity much faster than previously planned has sparked warnings Australia needs to speed up a transition away from fossil fuel exports.

A draft revised energy mix released by Japanese officials on Wednesday said the country – Australia’s biggest market for liquefied natural gas (LNG) and thermal coal – would cut gas-fired electricity generation nearly in half and reduce coal power by more than a third by 2030.

The Australian government pushed back fiercely against Unesco’s recommendation – and the world is watching

This year, Australia’s big tourism drawcard celebrates its 40th year as a UN world heritage site – a list where more than 1,100 of humanity’s most important spots go for acknowledgement and protection.

But on Friday, a committee of 21 countries will decide if it wants to listen to the advice of the UN’s science and culture organisation, Unesco, and put the Great Barrier Reef on its list of places that are “in danger”.

Climate Change Committee head says firms must invest in ‘scaleable’ offsets such as carbon capture

The aviation industry must pay for costly carbon removal technologies rather than rely on using the planting of trees to claim they are reducing emissions, the head of the Climate Change Committee has said.

Chris Stark said aviation, unlike other transport sectors, was unlikely to meet targets for net zero by 2050. He said instead the industry had to use “scaleable” offsets that matched ongoing emissions into future decades, but that these should be used as a last resort after directly cutting emissions.

A removal project aims to reduce numbers of the unwelcome arrival that has quickly become prevalent

Non-native lionfish have become increasingly common in parts of the Mediterranean in recent years, threatening local ecosystems and posing a hazard to humans through their venomous spines.

Marine biologist Prof Jason Hall-Spencer first saw a lionfish off the coast of Cyprus in 2016. It was just an individual, but the species – which produce about 2 million eggs each year and lack natural predators in their new environment – have quickly become prevalent. “In some places, I’ve seen 40 on one dive,” said Hall-Spencer, from the University of Plymouth.

Researchers find ‘significant relationship’ between stony coral tissue loss disease and nearby shipping

A virulent and fast-moving coral disease that has swept through the Caribbean could be linked to waste or ballast water from ships, according to research.

The deadly infection, known as stony coral tissue loss disease (SCTLD), was first identified in Florida in 2014, and has since moved through the region, causing great concern among scientists.

The politics of this new, extreme individualism will make collective responses to social crises impossible

Soon, a few of the more shameless newspaper commentators will urge the rest of us to “learn to live” with climate breakdown. Soon, a couple of especially sharp-elbowed cabinet ministers will sigh to the Spectator that, yes, carbon emissions should ideally be slashed – but we must make a trade-off between “lives and livelihoods”. Soon, a little platoon of Tory backbenchers will respond to TV pictures of another devastating flash flood or deadly heatwave by complaining about “fearmongering”. “Why is the BBC so doomy?” they’ll ask, as the death toll rises.

Soon, shockingly soon, the cheap shots, the brazen stat-bending and the coprophagic cynicism that have warped British discourse since March 2020 will migrate from Covid to an even bigger and more lethal crisis: the climate emergency. And just as they have helped shape the self-inflicted catastrophe that England has embarked upon this week, so they will work their terrible influence on that one.

A new study shows carbon pollution on the same route can vary sharply but consumers currently cannot make informed choices

Commercial flying is a real carbon bomb as emissions from commercial aviation are growing rapidly and are on track to triple by 2050, when they could make up about a quarter of the global carbon budget.

But now a new study shows how people could reduce their emissions while still flying on airplanes, if they were able to choose the most carbon-friendly routes.

We have an opportunity to reorient our lives back towards nature, reshaping our economy to benefit all Australians – human and non-human

Australian wildlife. Koalas, platypus, wallabies. We use them as our emblems, put them on our coins, name our sporting teams after them and companies use them as logos. Echidnas, dingoes, kangaroos. They are part of the fabric of our national identity. And so they should be. Most of them are found nowhere else on Earth. Wombats, numbats, bettongs. This continent is home to an amazing diversity of plants and animals, not to mention the unique landscapes they call home. They make Australia what it is and were here long before humans arrived. Antechinus, quolls, phascogales. But do we actually care about them? Of course we do! But can we honestly say that, if we judge ourselves by our actions?
