Is This ‘The Coldest Summer Of The Rest Of Our Lives’?

The part of the UK I’m in is about to experience about a week’s worth of 30°C+ weather, meaning we’re in for yet another official heatwave.

This comes after March temperatures so high that they broke not one, but two records, and the hottest UK June day we’ve ever noted. Schools closed during the last heatwave; wildfires raged; trains were cancelled, and buses caught on fire.

All this is taking place while an El Niño intensifies. It’s part of a decades-long warming trend that seems to be getting worse, not better.

So is it right to say, as I’ve heard expressed in various online spaces and various publications, that this is “the coldest summer for the rest of our lives”?

The sentence rightly points to the indisputable fact that global warming is going to get more dangerous if we don’t intervene. Heatwaves have already become more likely and more extreme.

But climate is different from weather – on a summer-by-summer basis, are we going to experience conditions worse than these every year? And what does it mean if we don’t?

We asked climate experts to share their thoughts.

“This is definitely the ‘least extreme weather’ we will experience”

Speaking to HuffPost UK, Professor Lorraine Whitmarsh, MBE, the director of the Centre for Climate Change and Social Transformations (CAST) and a Professor of Environmental Psychology at the University of Bath, said 2026 will probably pale in comparison to future weather events.

“I would say this is definitely the ‘least extreme weather’ we will experience,” Prof Whitmarsh told us.

“This is how Prof Hayley Fowler puts it, who is an expert in climate impacts.”

The professor was referring to 2025′s National Emergency Briefing by Professor of Climate Change Impacts at Newcastle University, Prof Hayley Fowler.

Still, Prof Whitmarsh added, “there’s no guarantee every year will see a hotter summer than the one before, but the general trend is certainly hotter over time”.

″‘This is the coldest year for the rest of our lives’ is very unlikely to be true”

HuffPost UK also spoke to climatologist Prof Friederike Otto, a Professor in Climate Science at the Centre for Environmental Policy at Imperial College London and the leader of World Weather Attribution (WWA).

She told us, “I think [the idea that] ‘this is the coldest year for the rest of our lives’ is very unlikely to be true, but what is certain is that unless we stop burning fossil fuels extremely rapidly and global mean temperatures are stabilised around 1.5°C, this is one of the cooler summers for the rest of our lives.”

While there may be cooler summers, and even colder overall years, ahead, in the bigger picture, 2026′s endless heatwaves might go down as a regular – even moderate – example of a “new normal”.

This is especially true if we do not urgently address climate change.
