Heatwaves are expected to more than double in duration after a one-degree rise in temperatures across the UK, an expert has warned. Professor Liz Bentley, executive director of the Royal Meteorological Society, explained that heat waves have fallen from an average of five days to 13 days. Speaking to GB News, Professor Bentley said: âTemperature records are quite high and the hottest years have occurred since the turn of the century.
âOur top 10 records have been broken in the past 20 years and we have seen a one-degree warming in the past 50 years.
âOne degree doesn’t sound like a lot, but it does mean we’re going to see more extreme heatwave episodes.
âThe frequency of heat waves will increase, the duration will increase.
âWe have noticed that over the past 30 years, the length of time has gone from about five days on average to 13 days on average to have episodes of extreme heat.

“We’re starting to see more tropical nights, this is where the temperature doesn’t drop below 20 Â° C.”
She added: “Temperatures in the UK could exceed 40C over the next decade. Small changes in average temperature mean very big changes in extreme heat waves such as heat waves and heat waves. flooding which we are likely to see continue in the future. “
It comes as the UK must prepare for both increasingly frequent floods and droughts and invest in “more capacity to store water when it rains,” an infrastructure expert said.
The call comes on the day leading meteorologists warn the UK will experience an increase in extreme weather events due to the climate crisis.
Data published in The State Of The UK Climate 2020 report revealed that last year was the third hottest, fifth wettest and eighth sunniest year on record – the first to make the top 10 for the three variables.
National Infrastructure Commission Chairman Sir John Armitt told Radio 4’s World at One about the need to prepare for more floods and droughts after being asked about recent flash flooding in the UK United.
He said: “It’s not just the floods, of course we are facing drought, and we have to get used to using less water, each of us at the same time, because we have to invest in more. capacity to store water when it rains. “
The commission chaired by Sir John said the government will only meet its climate change obligations if it commits to using new technologies to reduce carbon emissions.

But when asked if the new technology could include spraying seawater into the atmosphere, mirrors reflecting sunlight back into space, or other proposed solutions, Sir John called these of “fantastic”.
He said the government should instead encourage the adoption of existing technology that would help reduce carbon emissions.
Sir John said: “Some of these futures seem to be pretty fancy.”
He added: âThere are a lot of uncertainties, so in a sense the most important thing we can do is manage the things that we know, for example the electrification of vehicles, and making sure the opportunity is there for everyone in the next 10 years will get used to having an electric car instead of a gasoline car. “
