Core Insights - The North China rainy season has been notably prolonged this year, lasting 55 days as of August 28, compared to the average of 30 days, marking the earliest start since 1961 [1][2][4] - The rainy season has been characterized by increased rainfall, with cumulative precipitation exceeding the normal value by 131% as of August 25 [1][2] - Multiple factors contribute to the extended duration and intensity of the rainy season, including abnormal sea surface temperatures in the equatorial Pacific and a strong subtropical high pressure system [4][5][6] Rainfall Characteristics - There have been 29 significant rainfall events since the onset of the rainy season, with 10 classified as strong and 2 as exceptionally strong [2] - Notable rainfall amounts include over 250 mm in certain areas, with specific locations like Beijing's Miyun District recording 573.5 mm and Baoding in Hebei reaching 605.8 mm [2][5] Climate Change Implications - The record-breaking rainy season is seen as a local manifestation of global climate system changes, with increasing frequency and intensity of extreme weather events [6][7] - Experts suggest that the duration of the rainy season may continue to exhibit interdecadal variability, with a trend of increasing duration observed since 2011 [6][7]

Core Viewpoint - The article highlights the increasing frequency and intensity of extreme weather events due to climate change, emphasizing the urgent need for global action to mitigate these effects and achieve the 1.5°C temperature control target [2][3][17]. Group 1: Extreme Weather Events - The World Meteorological Organization (WMO) reported that the past decade has been the hottest on record, with human activities significantly altering climate patterns and increasing the occurrence of extreme weather events [3][17]. - A study indicates that children born after 2020 are likely to experience extreme weather events 2 to 7 times more than those born in 1960, depending on the type of climate disaster [18][19]. Group 2: Impact of Air Pollution on Snowfall - Research from the University of Tartu found that industrial aerosols can enhance snowfall by affecting cloud properties, leading to increased snowfall in polluted areas [5][6][11]. - The study identified 67 locations where pollution sources, primarily industrial facilities, influenced cloud formation and snowfall, with one event covering an area of 2,200 square kilometers and resulting in 15 mm of snowfall [6][9]. Group 3: Mediterranean Hurricanes and Flooding - The Mediterranean hurricane "Daniel" caused unprecedented flooding in Libya, with rainfall reaching 400 mm in 24 hours, 267 times the average daily rainfall for September [15][16]. - Climate change has intensified Mediterranean hurricanes, increasing their strength and likelihood of landfall, which poses significant risks to arid regions like Libya [14][16]. Group 4: Urgency of Global Climate Action - A study published in Nature outlines three global warming scenarios, indicating that without significant policy changes, the world could see a temperature rise of 2.7°C by 2100, far exceeding safe limits [21][22]. - The article calls for immediate action from countries and individuals to transition to renewable energy, innovate green technologies, and implement policy changes to combat climate change effectively [21][22].

Core Insights - The research published in the journal "Nature" indicates that approximately 52% of individuals born in 2020 will face unprecedented heatwave exposure risks under a 1.5°C warming scenario, compared to only 16% of those born in 1960 [1][3]. Group 1: Research Findings - The study predicts that under current mitigation policies aiming for a 2.7°C increase by 2100, the exposure risk for those born in 2020 will double compared to those born in 1960 [3]. - Among the 1960 cohort, about 16% (13 million people) will face unprecedented lifetime heatwave exposure risks, while for the 2020 cohort, this figure rises to approximately 52% (62 million people) if warming reaches 1.5°C, and up to 92% if it escalates to 3.5°C [3][4]. Group 2: Broader Implications - The study expands its analysis to include five additional extreme climate events (crop failure, wildfires, droughts, river flooding, and tropical cyclones), finding that exposure levels will significantly increase with each successive birth cohort [4]. - It highlights that within each birth cohort, the socio-economically vulnerable groups are more likely to face higher degrees of exposure to extreme climate events compared to their less vulnerable counterparts [4].
