“…In the same year, the world faced large impacts from the COVID-19 pandemic [5,6]. In 2021, North America experienced unusual high temperatures, with July becoming the hottest month on record globally, while Europe faced record-breaking rainfall and flooding [7,8]. In the summer of 2022, the Northern Hemisphere was hit by exceptionally high temperatures, with a European heatwave causing over 1000 deaths, multiple countries declaring emergencies, and the UK issuing its first-ever "extreme heat" red warning [9].…”

Global energy consumption is growing rapidly, with the frequency and intensity of extreme events constantly increasing, posing a long-term threat to power supply and consumption. Therefore, analyzing the spatiotemporal characteristics of electricity consumption and quantitatively assessing the impact of extreme events on electricity consumption are of great significance. Based on fine-grained electricity consumption data from Europe for the years 2019–2022, this paper employs a data mining perspective and four methods including Z-score, Isolation Forest, Local Outlier Factor, and Autoencoder to detect abnormal electricity consumption during extreme events. Additionally, it combines indicators such as elastic loss, vulnerability, and duration to measure the impact of extreme events on electricity consumption. It is found that low temperatures could lead to abrupt changes in electricity consumption, with Northern Europe being more significantly affected by low temperatures. The COVID-19 pandemic had the most significant impact on electricity consumption in Europe, with the middle part of Europe being the hardest hit during the first wave of the pandemic. Electricity anomalies during the pandemic period were related to national pandemic control policies and exhibited some lag. High temperatures persisted for a longer duration in the middle part of Europe.

Concentrations of greenhouse gases reached record levels in 2022 and energy continued to accumulate in the climate system. Despite the cooling influence of ongoing La Niña conditions, globally 2022 was the fifth or sixth warmest year on record. We give a summary of the global climate with a focus on the United Kingdom and Europe. Notably, the United Kingdom had its warmest year on record, including a brief record‐breaking heatwave in which multiple stations exceeded 40°C for the first time. The previous maximum temperature record of the United Kingdom was surpassed by the considerable margin of 1.6 degC on 19 July.
