Core Viewpoint - Climate extremization has become a norm, with global warming leading to intensified rainfall and drought conditions in specific regions, resulting in sudden shifts between drought and flooding [1][3][8]. Group 1: Extreme Weather Events - Recent years have seen a significant increase in extreme weather events globally, with high temperatures, floods, and storms becoming more frequent and intense [5][6]. - In July, the average temperature in Henan Province reached 30.5°C, 3.2°C higher than the historical average, marking the hottest period in 64 years [2]. - Northern China experienced above-average rainfall, with Inner Mongolia recording the highest precipitation for this period since 1961 [2][3]. Group 2: Impact on Agriculture - Extreme weather is adversely affecting major grain-producing areas in China, with high temperatures and heavy rainfall impacting crop growth and increasing irrigation costs [3][14]. - The growth of winter wheat is particularly vulnerable to insufficient low-temperature periods, which can lead to premature ear formation and reduced yields [15]. - High temperatures can cause corn leaves to curl, affecting photosynthesis and increasing water requirements, thus raising irrigation costs for farmers [15]. Group 3: Future Projections and Preparedness - The ongoing climate crisis requires urgent action, with a need for five times the current effort to effectively address climate challenges [11]. - Transitioning to green renewable energy is essential, despite the associated costs, as it presents significant industrial opportunities while mitigating future disaster losses [11]. - The upcoming weather patterns indicate that northern regions may continue to face flooding, while southern areas will experience heightened drought conditions [12]. Group 4: Economic Implications - The volatility of agricultural prices due to extreme weather events is expected to persist, with "weather-related price hikes" becoming more common [16]. - Developing countries may be disproportionately affected by extreme climate events, leading to potential resource conflicts and social instability [17]. - Industries related to agriculture may need to adapt their insurance models and financial tools to better manage the risks associated with climate change [18]. Group 5: Urban Planning and Infrastructure - The concept of sponge cities is being emphasized, but their capacity to handle extreme rainfall is limited, necessitating additional strategies for flood management [19][20]. - Urban planning must evolve to incorporate designs that can effectively manage high temperatures and heavy rainfall, ensuring resilience against climate impacts [18][20].
