![]() With changes evident at even 1.5☌ of global warming this is a reminder that even with the most optimistic global emissions mitigation scenarios there is still a need for adaptation, long-term planning and risk assessment activities across sectors in the UK. “Importantly, the paper shows that the increase in high-impact weather is reduced if global warming is kept as low as possible, showing that efforts to reduce human-induced climate change will curb the most severe impacts of future weather in the UK.” Severe weather can impact us in a number of ways, from our health, to flooding, food availability and transport issues. ![]() Lead author Dr Helen Hanlon, said: “Our research clearly shows that the more we warm the planet through human-induced climate change, the more severe weather we can expect in the UK. More frequency and severe long-term droughts, with droughts at least as severe as seen in 2010 increasing by 146%, at a 4.0☌ level of global warming and 86% more frequent by 2.0☌.With a 2.0☌ rise we’d expect to see around 34 days (range 27-44 days) per year. In a world that has increased to 4.0☌, the UK would expect to record 12 days (range 9-21 days) per year. The number of days when temperatures fall below 0.0C are likely to become less frequentĬurrently there are around 50 days (range 45-56 days per year) where temperatures dip below 0.0☌ each year in the UK.Under a 2.0☌ rise in global temperature it is expected England and Wales will receive 9 days (range 8-10 days) of intense and prolonged rainfall. The number of days of high-impact heavy rainfall in the UK leading to severe weather warnings could rise by three days per yearĬurrently, there are around 7 days per year (range 6-9 days) in England and Wales with intense and prolonged rainfall that could lead to river flooding. With a 4.0☌ rise in global temperature this could rise to 11 days per year (range 10-13 days).With a 2.0☌ rise in average global temperature the number of days exceeding 25.0☌ is calculated to be 18 days per year. Posing increasing risk to human health from extreme heat. The number of extremely hot days in the UK could increase four-foldĬurrently days exceeding 25.0☌ could rise from around 10 days a year now (range 8-11 days) to 37 days (range 32-46 days with a 4.0☌ rise in global warming.Visit the microsite here.The study, published in the journal Climatic Change, found that the higher the level of global warming, the projected increase in frequency or severity or both will be stronger for hot weather, droughts and flooding in the UK. These high-impact weather events can cause significant disruption across the UK affecting sectors such as health, transport, agriculture and energy. Read more about the Raising Risk Awareness initiative here. This can help decision-makers and the public to prioritise adaptation solutions and reduce vulnerability. ![]() It allows scientists to make quantitative statements about how climate change has altered the risk of extreme weather events occurring. Here, Raising Risk Awareness presents the Swahili version of an infographic which sets out why attributing extreme weather events is critical and how the process works. The Raising Risk Awareness initiative brings together scientists, vulnerability experts and knowledge brokers to understand the role of climate change in extreme weather events to help prepare for future ones.
