Core Viewpoint - The article discusses the normalization of heatwaves globally, emphasizing their impact on human health, economic security, and ecological systems, driven primarily by human-induced greenhouse gas emissions [2]. Economic Impact of High Temperatures - Extreme heat has led to significant labor hour and income losses, with direct impacts on production systems, including industrial power restrictions and increased logistics costs due to lower water levels [3]. - Indirect effects include supply chain disruptions, rising energy costs, and food inflation due to agricultural losses [3]. Tourism Sector Changes - Historical data indicates that for every 1°C increase in temperature, tourist arrivals decrease by approximately 8.1%, leading to a 6% drop in tourism revenue [4]. - High temperatures are shifting consumer preferences from sightseeing to wellness tourism, a trend likely to persist as extreme heat events become more frequent [4]. Renewable Energy Demand - The surge in electricity demand during heatwaves is stimulating the growth of renewable energy installations, particularly solar power, which aligns with peak electricity usage during sunny periods [7]. - The integration of meteorological data with industrial operations is crucial for optimizing energy supply and demand during extreme heat events [5][6]. Regional Challenges and Opportunities - Coastal regions face challenges such as increased temperature control costs in high-end manufacturing, while opportunities exist in developing smart energy networks and heat-resistant materials [9]. - The central and western agricultural regions must address irrigation shortages and crop yield reductions, with potential growth in solar agriculture and climate-resilient crops [9]. Infrastructure and Policy Recommendations - Recommendations for urban planning include creating green spaces, enhancing building energy efficiency, and developing smart grids to manage electricity resources effectively [10]. - In agriculture, promoting efficient irrigation techniques and developing heat-resistant crop varieties are essential strategies to mitigate the impacts of extreme heat [10]. Learning from Global Practices - Successful international practices include Cambodia's drought-resistant crop initiatives and Spain's weather index insurance for crops, which could be adapted to improve resilience in China [11][13]. - The EU's push for renewable energy transition serves as a model for reducing reliance on fossil fuels [12][14].

Group 1 - The phenomenon of heatwaves has become a normalized trend globally, posing threats to human health, economic security, and ecological systems [3][7] - Human activities, particularly greenhouse gas emissions since the Industrial Revolution, are identified as the primary drivers of extreme temperature changes [4][5] - In China, the average number of high-temperature days has increased by 25% over the past decade, with extreme heat events evolving into continuous compound disasters [6][24] Group 2 - High temperatures have led to significant income losses globally, with potential labor hours and income losses reaching new highs [8] - Direct impacts of extreme heat on the economy include physical shocks to production systems, such as industrial power restrictions and increased logistics costs due to lower water levels [9][10] - Indirect impacts manifest through supply chain disruptions and rising food inflation due to agricultural losses and transportation issues [10][11] Group 3 - The tourism industry is experiencing shifts, with a decrease in visitors to traditional scenic spots and an increase in demand for summer retreat destinations, as temperatures rise [13][15] - Historical data indicates that for every 1°C increase in temperature, tourist arrivals decrease by approximately 8.1%, leading to a 6% reduction in tourism revenue [13] Group 4 - The extreme heat has stimulated demand for renewable energy installations, particularly solar power, as high temperatures coincide with peak electricity demand [22] - Collaborative mechanisms between climate and energy departments are being established to predict and manage electricity demand during heatwaves [18][19] - The pressure from high temperatures is accelerating the development of smart energy networks and the adoption of heat-resistant materials in coastal regions [25][21] Group 5 - Different regions in China face unique challenges and opportunities in responding to high temperatures, with coastal areas focusing on high-tech solutions and the central and western regions addressing agricultural water shortages [24][26] - Infrastructure improvements, such as urban planning and agricultural adaptations, are essential to mitigate the impacts of extreme heat on economic development [27][29] - Learning from international experiences, China can enhance its agricultural resilience through drought-resistant crop varieties and innovative insurance mechanisms [31][36]
