Climate scepticism is a killer


The small city of Silopi in Turkey’s Şırnak province made unwanted history on 25 July 2025 when temperatures surged to 50.5°C (122.9F) – a record not only for Turkey but for continental Europe. 

This broke the country’s previous record of 49.5C set just two years earlier and came amid a wider pattern of searing heat across the region. 

But just as the atmosphere cracked under the weight of heat and smoke, a parallel blaze of apathy dominated the comments of social media posts. 

This is not just weather. It is signal and the fact that so many brush it off as meaningless should alarm us as much as the rising mercury.

The numbers are startling:

•    50.5C in Silopi, verified by Turkish meteorological authorities, marking the hottest temperature ever recorded in the country

•    132 weather stations reported record highs or lows across the country on the same day

•    in cities like Bursa and Karabuk, more than 3,500 residents were evacuated due to wildfires

•    over 80 blazes burned simultaneously in southern and western provinces

•    the death toll – still rising at the time of writing – included firefighters, volunteers and civilians, some overcome by flames, others by the heat itself.

Turkey was not an isolated flashpoint but more akin to the leading edge of a continental burn. In Greece, Italy and across the eastern Mediterranean, similar conditions have prevailed. 

And yet: “Just a hot day.”

Scrolling through the UK Met Office’s Facebook post about Turkey’s record heat, one might expect concern, curiosity or even a sober call for concerted action. 

Instead the voices of indifference seem to shout loudest with many of the top comments veering toward minimisation:

    “It’s Turkey. It’s always hot.”
    “It’s summer. Get over it.”
    “Every year you say it’s the hottest ever – so what?”

Such remarks aren't surprising anymore but they are disappointing and dangerous.

What we’re seeing isn’t a few keyboard cynics. It’s a growing climate indifference – a conditioned reflex to ignore or downplay events that no longer feel shocking. 

It’s as if the extremes scientists have warned about have become background noise. But to those on the ground – displaced, grieving, choking in smoke – it’s all very real.  

Climate context
This summer’s heat in the northern hemisphere is part of a wider and well-documented trend:

•    Europe is warming twice as fast as the global average.

•    the frequency and duration of heatwaves across the Mediterranean has tripled in the past 20 years.

•    attribution science has made it clear – events like Turkey’s 50.5C day are virtually impossible in the short term without human-induced climate change.

So, no, this is not just “a hot day” for the record books. It is part of a pattern that is remaking our seasons, our safety and our stories of the future. 

Survivability
As global temperatures rise, there’s a growing and often overlooked truth: above certain thresholds, the human body simply cannot survive for long without artificial cooling. 

It is widely accepted that a 35C wet-bulb temperature – a combination of heat and humidity – marks the upper physiological limit for humans. 

Beyond this, sweating becomes ineffective, the body can no longer cool itself and death can occur within hours, even in the shade. In dry heat, conditions above 45-50C without shade, ventilation or hydration can lead to heatstroke, organ failure, and death. 

Turkey’s new record is dangerously close to these thresholds and in a world where access to air conditioning and reliable electricity is not universal, especially in rural or low-income communities, this is no longer just a matter of discomfort.  

Complicit indifference 
It’s tempting to see social media as a misinformation sideshow. But the stories we tell – and the ones we ignore – shape public discourse and political will. 

If each new heat record becomes a meme or a punchline, we lose the urgency. And without urgency, we lose momentum. Indifference breeds delay. Delay costs lives.

That’s why this blog post is not just about numbers. It’s about meaning – about connecting the dots before the hairline cracks become fault lines.

In a moment like this, it's not enough to track the rising heat. We must also track the rising silence – the space where concern should be but isn’t. If records like Turkey’s 50.5C don’t register as wake-up calls, what will?

This is not hyperbole. It’s our future history and the tragedy is already unfolding more quickly than was predicted.

Transformation, if it comes, will demand not just awareness but imagination – a capacity to think far beyond fossil futures and current lifestyles.

Global connections

As temperatures across the UK soared again this week it is worth taking note of how meteorological events in one part of the world can trigger weather on the opposite side of the globe.

Last weekend the UK recorded a total of 62,277 lightning strikes as storms moved in from Spain and France.

This followed a mini heatwave which enveloped most of the country, bringing with it temperatures in the low 30s and by far the hottest day of the year so far.

And all this was because of a storm thousands of miles away - super typhoon Negouri which had been churning across the north west Pacific in the first week of July.

As well as bringing strong winds and heavy rain to Japan it also dragged a mass of tropical air northwards and gave the jet stream a kick in the process.

That set off a ripple effect along the jet stream, running across the Pacific and extending its influence out across the Atlantic, forcing the jet stream there to swing northwards across Europe.

This is what allowed the exceptionally warm and humid air - known as a Spanish plume - to spread up and across the UK, bringing a brief heatwave before breaking down with severe thunderstorms.

So, a storm over the north west Pacific can set off thunderstorms 10 days later some 10,000 miles away - illustrating in a very real way how the weather in one part of the globe is often directly influenced by what is happens elsewhere.

We’ve also had news this week - data released by NOAA (the National Oceanic and Atmospheric Administration) - that last month was Earth's warmest June since records began in 1880. It marked the second month in a row the world has set a warm-temperature record.

The average temperature over global surfaces for June 2014 was 1.3 degrees above the 20th century average of 59.9 degrees. In May, the Earth's temperature was 1.33 degrees above the average of 58.6 degrees.

"The warmth was fueled by record warm ocean temperatures," explained Jessica Blunden, a NOAA climate scientist.

"Large parts of the Pacific Ocean and most of the Indian Ocean hit record-high temperatures or were much warmer than average for the month."

Most of the world's land areas saw warmer-than-average monthly temperatures, with record warmth measured across part of southeastern Greenland, parts of northern South America, areas in eastern and central Africa, and sections of southern and southeastern Asia.

Every continent except Antarctica set temperature records and overall Earth's land areas in June were the seventh-warmest on record. It was also the 352nd consecutive month that the global temperature was above average.

So far, this year is tied with 2002 as the third warmest year on record, with a global temperature about 1.21 degrees above average.

According to NOAA, the last below-average global temperature for June was in 1976 and the last below-average global temperature for any month was February 1985.

It seems likely more records will be broken in the coming months as global warming combines with an emerging El Niño (see Countdown to El Niño).

NOAA currently puts the chance of El Niño forming at about 70% during the northern hemisphere summer and close to 80% during the autumn and early winter.
