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]

Core Viewpoint - The necessity of carbon reduction is emphasized as a self-driven initiative for China, rather than a response to external pressures [1] Group 1: Understanding Carbon and Its Implications - "Carbon" in the context of carbon reduction refers to greenhouse gases, primarily carbon dioxide, which is closely linked to human activities [2] - The direct reason for carbon reduction is the threat of climate warming to human survival and civilization, with the UN warning of the direct link between increased greenhouse gas emissions and severe climate disasters [3] Group 2: International and Domestic Reasons for Carbon Reduction - Internationally, carbon reduction is essential for China to take on major country responsibilities and contribute to global environmental governance, enhancing its influence in the global environmental governance system [5] - Domestically, carbon reduction supports the green and low-carbon transformation of the economy, meeting the public's demand for a better ecological environment, and promoting sustainable development [6] Group 3: Economic and Environmental Benefits - The reduction of carbon emissions is linked to significant improvements in air quality, with PM2.5 concentrations in cities decreasing by over 30% from 2015 to 2023 [6] - China's renewable energy generation capacity is the largest globally, with a significant decrease in coal's share of energy consumption by 12.6 percentage points over the past decade [6] Group 4: Development and High-Quality Growth - The pursuit of carbon reduction aligns with the goal of achieving high-quality development, reflecting a transformation in development methods [8] - The commitment to carbon reduction remains steadfast despite some countries retreating from their commitments, indicating a focus on sustainable and high-quality growth [8]
