Every heatwave occurring today is made more likely and intense by human-caused climate change. Early estimates by the UK Met Office suggest that days over 40°C have become ten times more likely to happen in the UK as a result of the rising global temperature.
But even this may be a significant underestimate, as models have underrated increases in the occurrence of extreme heat events before. And we know that climate change has increased the likelihood of new high-temperature records more than any other extreme weather phenomenon.
