High temperatures a ‘wake-up call for climate change’

The Met Office has issued its first red warning for extreme heat.

The record temperatures predicted next week are a “wake-up call” for climate change, an expert has said.

On Friday, the Met Office issued its first red warning for extreme heat, predicting a 50% chance of temperatures reaching 40C somewhere in the UK early next week.

Professor Hannah Cloke, climate expert and natural hazards lecturer at the University of Reading, said: “I think these types of temperatures will be seen more often which is very worrying because many people will die.

“This is a wake-up call for climate change.

“We are going to see these worsening hot summers but we can stop it getting really, really bad if we do something now.

“This cannot be reversed. We are locked into climate change and we need to work out what we are going to do about it.”

Prof Cloke said heatwaves were becoming more frequent, more intense and were lasting longer.

She said adaptations would need to be made to cope with rising temperatures.

“The UK Government does need to take it more seriously than they are doing,” she said.

“New houses should be set up to deal with this kind of heat when they are built.”

Prof Cloke warned health services could be overwhelmed during the heatwave and there would be risks such as heatstroke and dehydration for everyone, but particularly for the vulnerable and elderly.

The Met Office said the likelihood of extremely hot days in the UK was increasing and would continue to do so during the course of the century.

Climate attribution scientist at the Met Office Dr Nikos Christidis said: “The chances of seeing 40C days in the UK could be as much as 10 times more likely in the current climate than under a natural climate unaffected by human influence.

“The likelihood of exceeding 40C anywhere in the UK in a given year has also been rapidly increasing, and, even with current pledges on emissions reductions, such extremes could be taking place every 15 years in the climate of 2100.”
