The Guardian: Listen to Britain’s Dawn chorus of 1976, illustrating the Dramatic Loss of Birdsong in 50 years

The Guardian: Listen to Britain’s dawn chorus of 1976 – the dramatic loss of birdsong in 50 years.

The Guardian recreated a decade-by-decade audio landscape of what the past morning symphonies of birds sounded like before 73 million of them were lost over the past five decades in Great Britain. The story also mentions a ‘shifting baseline syndrome’, a gradual shifting of accepted norms that applies, in this case to the natural environment, be it habit loss, species decline or the rapidly rising temperatures brought on by the climate crisis.

“What we have is a shifting baseline,” said Dr Rob Robinson, a senior scientist at the BTO who researches wild bird populations. “People engaging in nature today are going to think the numbers they are seeing are normal, particularly children. But if you go back 50 years, they would have been able to experience a much richer environment.”

And

This “shifting baseline syndrome” – a gradual shifting of the accepted norm when it comes to the natural environment – is, said nature writer Robert Macfarlane, an “enormously powerful and I think very pernicious, psychological mechanism whereby each new generation measures loss from the degraded baseline that it grew up into. We’re part of a web. We’re wired into the wild world. Birds help us remember that, and they can do it in a very everyday way.”

Give it a listen – possibly the most mindful 35 seconds you’ll experience today.

Western Europe records its hottest June after searing heatwave

It’s Official – Copernicus: Western Europe records its hottest June after searing heatwave

It was also the second hottest June ever for the planet as a whole. The Copernicus Climate Change Service’s report for the month is here.

A summary from France24’s report:

The EU’s climate monitor said Thursday that Western Europe this year experienced its hottest month of June on record as an intense heatwave swept across the world’s fastest-warming continent. A “heat dome” weather effect – a high-pressure system acting like a lid on a boiling pot – led to all-time and monthly temperature records in several countries.

The report comes as a new heatwave is battering Europe this week, following a record-breaking one in June and an unusually early spring hot spell in May.

The average temperature in western Europe reached 20.74C in June, more than 3C above the 1991-2020 norm, according to the European Union‘s Copernicus Climate Change Service. It broke the region’s previous record set in June 2025.

“We will see more heatwaves in a warmer world,” said Samantha Burgess, strategic climate lead at the European Centre for Medium-Range Weather Forecasts (ECMWF), which operates Copernicus.

“They will be more intense and they will last longer, and they will impact more geographical areas,” Burgess told AFP.

The Atlantic: The Ticks are Winning – Gift Link

From a report published in 2023, on no longer not-so-hidden powers of tick saliva:

The secret behind tick stealth is tick saliva—a strange, slippery, and multifaceted fluid with no biological peer. It keeps the pests’ bites bizarrely itch- and pain-free, and allows them to feed unimpeded by their hosts’ immunity. As climate change remodels the world, spit is also what’s helping ticks enter new habitats and hosts—bringing with them the many deadly viruses, bacteria, and parasites they so often import.

NYT: How Heat Affects the Brain – Gift link

NYT: How Heat Affects the Brain – Gift Link

This week’s NYT Climate Forward newsletter surveys recent research into how brain function changes when temperatures rise.

A growing body of research has shown that our brains work differently when temperatures spike. Test scores fall and drivers honk more often. The good news is that we’re learning a lot more about how heat affects the brain. In fact, hundreds of peer-reviewed papers on the connection between heat and health have been published in recent years.

But there are longer-term effects of exposure to heat to consider, too. Recent research has found that hotter weather may make the brain more vulnerable to air pollution, increasing the risk for dementia and Parkinson’s disease.

And this, on the impacts of the air pollution and heat combination:

Exposure to particulate air pollution, known as PM 2.5, is associated with Alzheimer’s disease and dementia in older adults, they wrote. It can also affect brain development in young people, increasing the risk of anxiety and depression. The report cited an estimate that one in four dementia deaths is attributable to air pollution.

France records 2,025 excess deaths from heatwave, but data remains incomplete

France National Health Service Reports: France records 2,025 excess deaths from heatwave, but data remains incomplete.

Le Monde reports (subscription only):

A rapid-fire communication was aimed at quashing all speculation over deaths related to France’s record-breaking June heatwave, even if it meant presenting a partial picture that could get worse. In an update published on Friday, July 3, Santé publique France, the French national public health agency, estimated that 2,025 additional deaths were recorded between June 22 and June 28 compared to the previous week, an increase of 29.1%. While these figures should be interpreted with caution due to incomplete data, they offer a first snapshot of the fatal effects of the historic heatwave that swept across the country.

And from The Guardian’s report:

Public Health France said on Friday there had been “an increase of 29.1%, corresponding to 2,025 additional deaths compared with the previous week”. It said the figure was probably an underestimate and “mortality will rise further”.

Watch ‘Only a Child’, Oscar-shortlisted Visual Poem Celebrating 12-year-old’s 1992 Rio Summit Speech

In case you missed it, this is ‘Only a Child’, the 2022 Oscar-shortlisted animated short directed by Simone Giampaolo who brings together 20 animation directors to give shape, color, vibrance and a renewed urgency to the powerful speech delivered by Severn Cullis-Suzuki at the 1992 Earth Summit in Rio. She was 12 at the time and her presentation garnered worldwide attention.

”I’m only a child, yet I know we are all part of a family — five billion strong; in fact, 30 million species strong — and borders and governments will never change that. I’m only a child, yet I know we are all in this together and should act as one single world towards one single goal.”

Today in Nice – 29 June 2026

The heatwave that has been baking Europe for the last week is creeping eastward, but it still hit 34C (93F) late this afternoon in Nice and 33C (91F) in Monaco. And the airconditioning on the crowded 18:06 train from Monaco between the two wasn’t working. One passenger measured the temperature at 42C (108F). I watched passengers whose breathing labored. It was stifling.

World Weather Attribution report: Fossil fuel emissions have rapidly worsened European heatwaves in just a few decades

World Weather Attribution report: Fossil fuel emissions have rapidly worsened European heatwaves in just a few decades.

A study by World Weather Attribution released on Friday (26 June) shows that the heatwave that is currently baking much of Europe is the continent’s worst so far, in terms of heat stress and temperatures, and that the recipe of conditions that created it would have been virtually just 50 years ago. Brought to you by fossil fuels.

Some of the major findings:

  • Heatwaves cause more deaths in Europe than all other natural hazards combined
  • Vulnerability to heat has shifted over time, from primarily elderly people living alone to populations facing socioeconomic disadvantage and chronic illness, including homeless people and migrants, highlighting the need for adaptive, equity-focused heat-health policies.
  • In 1976, when some of the previous European records were set, the 2026 temperatures would have been virtually impossible to occur in June, while also highly unlikely at any time of the year. In 2003, the first major heatwave of this century, daytime heat like this would still have been very rare, about 10 times less likely than today, while nighttime temperatures such as this June would have been more than a hundred times less likely in 2003.
  • Across large parts of Western Europe, June is warming faster than any other month. In addition, daily maximum temperatures are warming faster than night time temperatures, though both are warming much faster than global warming. The hottest daily temperatures are warming at about triple the rate of global warming and night time temperatures at about twice the rate. Many capital cities are experiencing not only their hottest June 3-day period but also the hottest three-day period since 1950, according to the ERA5 dataset. However, due to global warming these temperatures are now no longer unusual during the summer months in many capitals.
  • This means that a similar heatwave in June would have been about 3.5°C cooler during the day in 1976 and about 2°C cooler in 2003. The nighttime temperatures would have been about 2.4°C cooler in June 1976 and about 1.3°C cooler in June 2003.
  • This June 2026 heatwave occurred under a circulation pattern broadly similar to historical analogues – Southerly Flow. However, a similar circulation pattern now produces significantly hotter temperatures than it did in the mid-20th century because the climate baseline has warmed.

And

  • This summer shows that at 1.4°C of global warming, extreme heat is already reaching the limits of our societies’ ability to cope. Our analysis here shows that intense heat is increasing rapidly even in living memory, with such events tens to hundreds of times more likely since only 2003 and virtually impossible just 50 years ago. A rapid phase-out of fossil fuels is critical if we are to avoid even higher temperatures and their consequences in the future.
