Core Viewpoint - The recent heatwaves in Europe and North America are attributed to climate change, leading to unprecedented high temperatures and extreme weather events, with predictions of more frequent occurrences in the future [2][10][12]. Group 1: Temperature Trends - ECMWF forecasts indicate that temperatures in most parts of Europe will be significantly above average in the coming days [2]. - June 2023 is recorded as the hottest June in England's history, with London temperatures expected to reach 35 degrees Celsius [6]. - In France, temperatures are reported to be 10 to 14 degrees Celsius higher than historical averages, with some areas reaching 46 degrees Celsius [8]. Group 2: Extreme Weather Events - The "double heat dome" phenomenon is causing prolonged high-pressure systems, leading to extreme heat, wildfires, and flooding [9]. - The European Centre for Medium-Range Weather Forecasts (ECMWF) indicates that many regions in Europe are experiencing daily average temperatures that align with typical July and August conditions, suggesting a trend towards more extreme weather [8]. Group 3: Climate Change Implications - Climate change is causing heatwaves to become more frequent and intense, affecting broader geographical areas [8][12]. - Current climate models are not fully capturing the effects of human-induced warming on weather patterns, leading to a need for updated models to predict future events accurately [10][11].

Core Points - The "heat dome" phenomenon is currently affecting millions in the Northern Hemisphere, particularly in Europe and the United States, leading to dangerously high temperatures [1][2] - Climate scientists report that the intensity and duration of such extreme atmospheric events have nearly doubled since the 1950s [1] - The UK experienced its hottest June on record, with temperatures in London expected to reach 35°C, while parts of the US saw temperatures exceed 40°C [1][4] Group 1 - The "heat dome" is characterized by high-pressure systems that trap hot air in a region, preventing cooler air from entering, resulting in heat waves [1][2] - In Europe, countries like Greece, Spain, and France are facing unprecedented heat, with temperatures deviating from seasonal averages by 10°C to 14°C [2] - The phenomenon is linked to human-induced climate change, which has increased greenhouse gas levels, making it harder for the Earth to release excess heat [2][10] Group 2 - Research indicates that the frequency of atmospheric blocking events, which lead to heat waves, wildfires, and floods, has increased significantly over the past 70 years [8] - The current "double heat dome" phenomenon is associated with persistent fluctuations in jet streams, which are not fully captured by existing climate models [10] - Experts warn that typical summer weather patterns are becoming a thing of the past, with extreme temperature and precipitation events becoming the norm [10]
