You thought it was hot now! Scientists predict the UK's average weather in the year 2080
Britain is in the midst of for the year but it could be just a taster of what's to come in a few decades. Scientists predict that temperatures across the UK in 2080 will be high enough to trigger 'wide-scale mortality', much like the . In a single summer week in 2080, temperatures will hit 41C (105F) in while weekly averages will be 28C (82F) in large parts of southern England. This compares to London's peak summertime temperatures of 31C (87F) and southern England's weekly averages of 20C (68F) in the 1970s. Manchester, meanwhile, will push past 38C (100F) at least once a week during a 2080s summer, and Plymouth and Glasgow will likely hit 35C (95F) weekly. Last year, the UK of 40.3C (104.5F) but multiple regions will push past this on a weekly basis by 2080, the predictions show. Temperatures in the biggest cities, namely London, tend to be hotter than the rest of the UK and will continue to be so in the 2080s due to densely-packed buildings and more concrete and tarmac that absorb heat more quickly. The study was led by Professor David Coley at the University of Bath's Department of Architecture and Civil Engineering, who stresses that it is in the extremes of weather, not the mean climate, where much climate change risk lies. 'Climate change is normally discussed in terms of seasonal averages, as this is what is meant by the word climate,' said Professor Coley. 'I believe this a possible mistake, as few of us naturally grasp how even small differences in climate imply hugely different worlds.' The team cite the European heatwave of 2003, which killed 14,000 people in Paris alone, showing the dangers of extreme temperatures rather than average temperatures. In the last 20 years alone there has been a 54 per cent increase in heat-related mortality in people older than 65, with a total of 296,000 deaths in 2018. 'It's such heatwaves and cold snaps, and a lack of preparation for them, that will increasingly kill people,' said Professor Coley. 'We need to think about climate change in terms of changing weather.' For their study, Professor Coley and colleagues produced a series of detailed weather projections for 11,326 UK locations at 3-mile-square intervals for the year 2080. Using weather generator software and a newly developed algorithm, the team built upon Met Office climate predictions to create the projections. After inputting the climate prediction data into the software, the weather generator produced 3,000 examples of possible weather forecasts for 2080. By then looking for heatwaves and examining how they changed over time, they discovered that there will be heatwaves of similar form as the 2003 Paris event. However, these will be 'with even higher temperatures', suggesting the likelihood of 'largescale mortality'. The authors say climate change has the potential to undermine many of the gains in public health over the past 50 years, which will 'exacerbate existing inequities'. Vulnerable populations, such as the elderly or those with pre-existing medical conditions, will be disproportionally affected. 'Exposure to high temperatures impact individuals via various routes from heat stress and heatstroke to exacerbations of respiratory and cardiovascular disease,' they write. What's more, the UK is badly prepared for temperature increases as buildings and infrastructure . 'No temperature record exists of the internal conditions within the buildings in which the 14,000 deaths occurred in Paris in 2003,' the team say. 'The predicted situation in London is similar to that found in Paris, but with the peak temperature being higher in London and the night-time temperature in London being considerably higher. 'It would therefore not be unreasonable to conclude that in the future the UK can expect events with moralities of similar number as Paris suffered.' Weather files containing the extreme weeks for 11,326 locations have been prepared by the academics and , while the study has been published in the journal .
