Core Viewpoint - The proposal by the U.S. Environmental Protection Agency to revoke the scientific finding on the dangers of greenhouse gas emissions to public health has sparked widespread controversy and opposition from the public, highlighting concerns over its scientific basis and alignment with public interest [1][5][20]. Group 1: Public Opinion - A majority of local residents interviewed expressed strong opposition to the proposal, citing a lack of scientific evidence and potential harm to public health and the economy [1][4][5]. - Residents emphasized the importance of environmental awareness and the negative implications of climate change for future generations, including issues like glacier melting and rising sea levels [7][9]. - There are concerns that the proposal serves the interests of a few wealthy groups rather than the public, potentially damaging the U.S.'s credibility in international climate negotiations [7][9]. Group 2: Government Actions and Policies - The U.S. government has been criticized for its lack of responsibility in addressing climate change, with actions such as withdrawing from the Paris Agreement and cutting federal funding for climate initiatives [12][18]. - The timing of the EPA's proposal coincides with commitments from other countries to purchase significant amounts of U.S. energy products, suggesting a focus on domestic political and economic interests [18][20]. - The proposal is seen as part of a broader trend of supporting traditional energy resources while dismantling previous administrations' green policies, which may lead to a reduction in environmental regulations [18][20]. Group 3: Legal and International Implications - Experts predict that the proposal will face significant legal challenges, with doubts about its scientific validity and potential backlash from the industrial sector [11][22]. - The U.S.'s withdrawal from global climate leadership could weaken international cooperation on climate issues, as other countries may use the U.S. stance as justification for their own inaction [24][26]. - The overall approach of the U.S. government is viewed as detrimental to global climate efforts, potentially undermining the collective goal of reducing greenhouse gas emissions [26].

Core Viewpoint - Climate change is a global challenge that impacts not only environmental protection but also energy security, social stability, and risk distribution [2] Group 1: Climate Change and Energy Security - The urgency and complexity of addressing climate change have intensified due to rising resource risks, trade protectionism, and sluggish global economic growth, particularly affecting underdeveloped regions [3] - Human activities have led to a global temperature increase of 1.2°C compared to pre-industrial levels, with a high probability of exceeding the 1.5°C threshold in the next five years [3] - Extreme weather poses systemic threats to energy systems, affecting wind power efficiency due to reduced wind speeds and increasing power supply tensions due to high temperatures and droughts [3] Group 2: Strategies for Energy Resilience - A model indicates that for every unit increase in the extreme climate risk index, total power generation will significantly decline, with wind power being the most affected [4] - Four strategies proposed to address these challenges include: 1. Establishing a climate risk monitoring and early warning system [4] 2. Optimizing diversified energy supply and promoting collaboration among wind, solar, hydro, and thermal power [4] 3. Creating an emergency mechanism for the electricity market under extreme climate conditions [4] 4. Innovating climate financial products, such as carbon asset insurance and green industry funds, to support energy resilience [4] Group 3: Comprehensive Development Goals (CDGs) - The report presented at the seminar critiques existing global development indicators, highlighting limitations in the Human Development Index (HDIs) and Sustainable Development Goals (SDGs) [5] - The new Comprehensive Development Goals (CDGs) framework emphasizes a "bottom-up, practice-driven" approach, focusing on "human development and social progress" across five dimensions: innovation, coordination, green development, openness, and sharing [5] - The CDGs report suggests incorporating natural capital into core indicators, increasing spatial dimension analysis, and utilizing AI technology for future trend predictions [6]

Core Viewpoint - The global insurance industry is facing a critical challenge as climate change leads to increasingly frequent extreme weather events, which may soon exceed the industry's capacity to provide coverage for financial services such as mortgages and investments [1][3]. Group 1: Insurance Industry Challenges - Allianz's board member, Gunther Thalinger, warns that the world is approaching a temperature level where insurance companies can no longer provide coverage for financial services like mortgages [3]. - Thalinger highlighted that losses from extreme weather are causing asset classes to "degrade in real-time," and the worsening climate crisis could potentially "destroy capitalism" [3]. - Approximately two-thirds of economic losses from natural disasters are currently uninsured, indicating a significant risk burden on individuals, businesses, and governments [3]. Group 2: Economic Impact of Natural Disasters - Zurich Insurance Group's report indicates that from 2014 to 2023, extreme weather events caused approximately $2 trillion in economic losses, with the frequency and intensity of disasters increasing due to long-term climate changes [4]. - The global insured loss growth rate (5.9%) has outpaced global economic growth over the past thirty years, suggesting a concerning trend for the insurance market [4]. - If the trend of increasing insured losses continues, insurance companies may need to raise climate-related premiums, which could affect individuals' and businesses' willingness and ability to purchase insurance [4].
