Core Viewpoint - The article emphasizes that global warming is a reality driven primarily by human activities, leading to increasingly extreme weather events and significant impacts on the environment and society [2][4]. Group 1: Causes of Global Warming - The scientific consensus is that human activities, particularly the emission of greenhouse gases like carbon dioxide and methane, are the main drivers of global warming, with current warming rates being 50 times faster than natural cycles [4]. - Industrial emissions and livestock farming, especially cattle, contribute significantly to greenhouse gas emissions, with methane being a major byproduct of cattle digestion [4][5]. Group 2: Effects of Global Warming - Global warming leads to more frequent and severe extreme weather events, including droughts, floods, and heatwaves, due to increased evaporation and changes in atmospheric moisture [8][9]. - The melting of glaciers and ice caps contributes to rising sea levels, but the more immediate concern is the increase in extreme weather patterns, which can lead to both droughts and floods [8][9]. - The phenomenon of "critical points" is highlighted, where irreversible changes, such as the melting of ice sheets and the release of methane from permafrost, could accelerate global warming and lead to more extreme climate conditions [12][13]. Group 3: Potential Benefits and Adaptations - One potential benefit of global warming is the northward shift of precipitation patterns, which could lead to increased rainfall in certain areas, although this does not guarantee improved agricultural conditions due to increased evaporation rates [14][15]. - The article discusses the possibility of adapting to extreme weather by changing living patterns, such as relocating to cooler regions during extreme heat [16]. Group 4: Societal Implications - Extreme weather events pose direct threats to vulnerable populations, exacerbating social inequalities and impacting livelihoods [16]. - The article notes that efforts in climate change mitigation, such as reforestation and renewable energy deployment, are crucial and highlights China's proactive measures in addressing global warming [16].

Core Viewpoint - The article discusses the increasing frequency and intensity of extreme weather events in China, including record high temperatures and heavy rainfall, attributed to climate change and the behavior of the subtropical high-pressure system [1][5][9]. Group 1: Extreme Weather Trends - China has experienced the hottest June on record, with extreme heat and heavy rainfall occurring simultaneously in different regions [1]. - The National Climate Center reports a general increase in extreme heat records and rainfall intensity across most regions in China over the past few decades [1][5]. - The average annual warm days in China have increased by approximately 6.7 days every decade, indicating a lengthening of the warm season [5]. Group 2: Climate Change Impacts - The article highlights that global warming is a significant factor contributing to the observed warming and increased humidity in northern China [5][9]. - The average relative humidity in Beijing has risen by 5% from 2013-2022 compared to 2003-2012, indicating a trend towards a warmer and more humid climate [3][4]. - The subtropical high-pressure system's behavior has changed, leading to earlier and more intense heat waves in northern regions [7][8]. Group 3: Weather Forecasting Challenges - There is a discrepancy between reported temperatures and public perception due to differences in measurement standards and personal experiences of weather [2]. - Future weather forecasts may increasingly focus on "feels-like" temperatures rather than just air temperature, addressing public concerns more effectively [2]. Group 4: Regional Weather Patterns - The article describes how the subtropical high-pressure system influences weather patterns, causing drought in some areas while leading to heavy rainfall in others, creating a "drought in a large area, flood in a narrow line" phenomenon [6][10]. - The intensity and frequency of localized extreme rainfall events are increasing, with significant implications for flood management and infrastructure [10][11]. Group 5: Adaptation and Preparedness - The article emphasizes the need for improved disaster preparedness and water resource management in light of increasing extreme weather events [12]. - It suggests that alongside disaster mitigation, there should be a focus on utilizing rainfall during flood seasons for water conservation in drier months [12].
