A new survey of nearly 130,000 people across 125 countries has found that there is widespread support for climate action around the world. But, people often don’t realise how much support there is.
The open access article, published in the journal Nature Climate Change, presents new, large-scale evidence of a global mandate for climate action, while shining a light on the pervasiveness of climate ‘perception gaps’. The headline findings across the global dataset show that:
However, this ‘actual’ support for climate action was at a mismatch with what people ‘perceived’ the levels of support to be. Around the world, people “systematically underestimate the willingness of their fellow citizens to act”.
And these discrepancies matter. If we don’t believe there’s a mandate for green policies, inertia slows the pace of the green transition. ‘Perception gaps’ like these have consequences.
Following months of sweltering heatwaves, record-breaking wildfires and five regions in drought, this week it was provisionally confirmed that 2025 was the UK’s hottest summer on record.
While this new record was made ‘70 times’ more likely by climate change, the overwhelming sentiment is that the country is not prepared for more summers like this. The UK’s official climate advisors, practitioners who work on the frontline of the heatwave response, and the British public all agree that the UK isn’t ready for more extreme weather,worsening heat, and compounding risks like water scarcity and wildfires.
At the same time, there are important perception gaps to address. Despite the alarming statistics about heat-related deaths in the UK, many people were looking forward to the first heatwaves this summer. Lots think that heatwaves will only become a problem for the UK in the future. And many believe that hot weather poses more of a risk to other people, not themselves.
In this context there are important conversations now happening about how to grapple with the growing climate risks in the UK, including the sudden lurch towards air conditioning (despite its potential to make heat risks worse).

A climate of silence in the UK?
New analysis from Climate Barometer reveals more than half of Britons say they ‘rarely’ or ‘never’ share their opinions on climate change in everyday conversations.
