Spain could face extreme heat conditions by 2070 if climate trends continue

It’s no longer just scientists talking in graphs and percentages. New climate projections are now showing, in a very real way, what the world could look like by 2070 – and for many places, including Spain, and the mediterranean Region, the changes could be hard to ignore.
We’re talking about cities that feel like deserts for months on end, rising sea levels creeping into coastal areas, and daily life shaped by heat, water stress and extreme weather. And the uncomfortable part? This isn’t some distant future. The path we’re on now is already pointing in that direction.
Why scientists are increasingly worried about the next few decades
For years, climate change has been explained through reports that most people never fully read. But the message behind them has been getting more direct.
The scientific consensus today is clear: if greenhouse gas emissions continue at the current pace, global temperatures will keep rising – and faster than many had expected just a decade ago.
Recent climate assessments suggest that key temperature thresholds could be crossed within the next ten years. That might sound like a technical detail, but it comes with very real consequences.
We’re talking about growing pressure on food production, ecosystems struggling to cope, and entire regions becoming harder to live in. Some research even suggests that by 2070, around a third of the world’s population could be living in climate conditions similar to what you’d find today in parts of the Sahara.
It’s not just about hotter summers. It’s about how entire environments shift.
From abstract data to real-life images: why this hits differently now
What’s changed recently is how this future is being shown.
Instead of just numbers, researchers are now using visual projections – realistic images and simulations – to help people understand what these changes actually mean.
Projects like Picturing Our Future, developed by Climate Central, compare two possible scenarios. One where emissions continue largely as they are, leading to around 3°C of global warming. And another where strong action is taken, keeping warming closer to 1.5°C.
Seeing the difference between the two is striking.
Cities like Seville or coastal areas in southern Europe look dramatically different depending on the path taken. In one version, heat dominates daily life, infrastructure is under pressure and coastlines shift. In the other, the changes are still there – but less extreme, more manageable.
It’s a simple idea, but an effective one. Because while most people can’t really picture what a “2 or 3 degree increase” means, they can understand what it looks like when familiar places start to feel unfamiliar.
What this could mean for people living in Spain
For anyone living in Spain – especially expats who chose the country for its climate and lifestyle – this hits close to home.
Spain is already feeling the effects. Summers are getting hotter, heatwaves are lasting longer, and water shortages are becoming more common in certain regions.
Looking ahead to 2070, the concern isn’t just about comfort – it’s about how daily life might change.
In cities like Alicante, Malaga or Valencia, higher average temperatures could make summers more intense and prolonged. Outdoor life, which is such a big part of living in Spain, could become more difficult during peak months.
Coastal areas, meanwhile, may have to deal with gradual sea-level rise. Not overnight flooding – but slow, steady changes that affect infrastructure, property and local economies over time.
For expats, that raises practical questions. Will homes need to adapt? Will energy costs rise as cooling becomes essential? Will some areas become less attractive to live in?
These aren’t questions for 2100. They’re questions that could start to matter within decades.
A future that isn’t completely fixed
And yet, despite how unsettling some of these projections are, there’s an important nuance.
None of this is set in stone.
The more optimistic scenario – the one where warming is limited to around 1.5°C – shows that the worst impacts can still be reduced. Cities remain liveable, extreme heat is less frequent, and the pressure on resources is more manageable.
That’s the part researchers are trying to highlight.
The goal of these visual projections isn’t just to alarm people – it’s to make the consequences easier to grasp, and to show that choices made today still matter.
In the end, what makes these images powerful isn’t just how dramatic they look.
It’s how familiar they feel. Because when you start to recognise your own city in those projections – or imagine your daily life under those conditions – the future suddenly stops feeling abstract.
And starts feeling a lot closer.
