Over the past two months, the UK has endured two heatwaves that shattered long-standing temperature records, a phenomenon unseen since 1911. The current June heatwave will dissipatedissipate/ˈdɪsɪpeɪt/L3逐渐消散或消失，尤指热量、云层或能量等逐渐减弱直至消失的过程to gradually disappear or disperse, especially in the context of heat, clouds, or energy losing intensity and vanishing over the weekend, but models indicate further spikes later in the summer. Forecasters have issued a three-month outlook suggesting higher-than-normal chances of hotter weather, with 'significant bursts' of heat expected. The weather rollercoaster began in May with a heat dome that set a new May record of 35.1°C in Kew Gardens. This was followed by a wet June and then another intense heatwave that broke the June all-time record. A red extreme heat warning was issued for only the second time since 2021, prompting school closures and transport strain.
Human-inducedhuman-induced/ˈhjuːmən ɪnˈdjuːst/L3由人类活动引起的，强调人为因素导致某种变化或现象caused or influenced by human activities, especially in the context of environmental or climatic changes climate change is shifting the baseline temperature higher, making heatwaves hotter, more frequent, and longer-lasting. Met Office scientists note that the likelihood of exceeding 40°C in the UK is accelerating; the first such occurrence was in July 2022 at Coningsby (40.3°C). Projectionsprojections/prəˈdʒɛkʃənz/L3基于现有数据或趋势对未来情况的预测或估计，尤指科学或统计上的推断estimates or forecasts of future situations based on current data or trends, often used in scientific or statistical contexts suggest that if global warming continues, temperatures in the mid-forties could become a serious possibility by 2050. World Weather Attribution concluded that the extreme June heat across Western Europe would have been 'impossible just a few decades ago.' Dr Theodore Keeping stated that the link is 'settled,' adding that continued fossil-fuel emissions are directly responsible for the disruption.
El Niño, the climate pattern that elevates global temperatures, has been officially declared in the Pacific Ocean. Occurring every two to seven years and lasting about a year, it typically raises global temperatures by 0.2°C. Some scientists predict it could become a 'Super El Niño,' defined by sea surface temperatures exceeding 1.5°C above average. However, its impact on weather patterns lags several months, so it is not expected to boost UK heatwaves this summer. For the UK, there is no discerniblediscernible/dɪˈsɜːrnəbəl/L3可察觉的、可辨别的，指能够通过观察或分析清楚识别出某种联系或差异able to be noticed, perceived, or clearly distinguished, especially in terms of a connection or difference link between summer heatwaves and El Niño. The most recognised impact is to slightly raise the likelihood of a colder winter, according to Dr James Pope.
