Group 1 - The article emphasizes that extreme weather events are becoming a norm due to climate change, with significant impacts on agriculture, urban operations, and daily life [3][4][6] - The average temperature in Henan province reached 30.5°C in July, which is 3.2°C higher than the historical average, marking the hottest period in 64 years [1][2] - The article highlights the urgent need for scientific understanding and effective responses to climate change challenges, as the current preparations are insufficient [11][12] Group 2 - The frequency of extreme weather events has increased significantly, with a notable rise in climate-related disasters over the past two decades [4][6] - The article discusses the dual impact of global warming, leading to more severe droughts and floods, which poses a threat to major grain-producing areas in China [3][8][16] - The agricultural sector is facing challenges such as increased irrigation costs and crop growth disruptions due to extreme temperatures [17][19] Group 3 - The article suggests that the transition to green energy is essential, requiring five times the current efforts to mitigate future disaster losses [12][13] - It points out that the agricultural infrastructure needs significant upgrades to adapt to extreme weather, including improved irrigation and drainage systems [20] - The potential for "weather-related price hikes" in agricultural products is highlighted, with extreme weather already causing fluctuations in global commodity prices [21][22] Group 4 - The article indicates that extreme weather will increasingly affect various industries, necessitating new financial tools for agricultural insurance [23] - It mentions that sectors like renewable energy and urban planning must adapt to the challenges posed by extreme weather events [24][25] - The need for a long-term strategy to combat climate change is emphasized, with a focus on adhering to national carbon neutrality goals [26]

Core Insights - The report from the Australian Institute of Marine Science indicates a significant decline in hard coral cover on the Great Barrier Reef due to climate change and other factors [1] Summary by Categories Coral Coverage - The average hard coral cover in the monitored areas of the Great Barrier Reef is projected to decrease by approximately 14% to 30% from 2024 to 2025, with some reefs experiencing declines of over 70% [1] Causes of Decline - The primary cause of the decline in hard coral coverage is attributed to a heatwave during the summer of the Southern Hemisphere in 2024, which led to widespread coral bleaching and mortality [1] - Other contributing factors include cyclonic impacts, flooding, and the activity of crown-of-thorns starfish, which exert additional pressure on coral survival [1] Coral Bleaching Phenomenon - Coral bleaching occurs when corals lose their symbiotic algae or the algae lose their pigmentation due to environmental stress, resulting in a loss of color [1] - While coral bleaching does not necessarily lead to coral death, reduced stress levels can allow corals to recover their color [1] Importance of the Great Barrier Reef - The Great Barrier Reef, located off the northeast coast of Australia, spans over 2,000 kilometers and is recognized as the world's largest coral reef system and one of the most complex natural ecosystems on Earth [1]

中化新网讯 近日，美国环境保护署(EPA)宣布了一项提议，建议撤销对温室气体的"危险认定"，即官方 不再认定温室气体对人类健康和福祉构成威胁。如果该提案最终获得通过，美国所有温室气体法规都将 失去法律依据，这可能会对未来应对全球变暖的努力造成毁灭性打击。 泽尔丁还估计，通过废除包括汽车排放标准在内的所有温室气体法规，取消其危险性认定，每年可节省 540亿美元的成本。泽尔丁援引了最高法院去年的一项裁决作为其废除法案的依据，该裁决认定EPA无 权监管温室气体。不过，他同时表示，如果国会修改《清洁空气法》，明确规定政府有义务监管温室气 体，EPA将遵守该裁决。 当地环保组织强烈反对该提案，批评称在全球变暖的负面影响愈加严重的情况下，美国应对气候变化的 途径将会中断。根据多个团体、部分州以及法律专家的说法，预计未来将有人提起诉讼，挑战该项提 案。 EPA署长泽尔丁在美国印第安纳州的一场活动上宣布该项提议，他与能源部长赖特一同出席了此次活 动。泽尔丁认为，此举反映了选民对监管机构保护经济的要求。泽尔丁表示"在特朗普总统的领导下， 我们将选择一条平衡环境保护与经济增长的道路"。 ...

日本气象厅说，日本气温再创新高缘于全球变暖，以及偏西风覆盖地区更靠北，带来温暖空气。 2024年，日本富士山顶11月初才出现积雪，比常年晚一个多月，创130年来最迟纪录。长期来看，日本 平均气温每100年上升1.4摄氏度，上世纪90年代以来，其升温趋势尤其明显。在日本年均气温最高的10 个年份里，2019至2024年占了6个。 北京商报综合报道 7月31日，日本大阪梅田区，早高峰通勤者在喷雾降温装置下等候公交车。 日本气象厅数据显示，7月30日当天，全国914处观测点中，271处气温超过35摄氏度；39处刷新高温纪 录。 极端天气给农业生产带来不利影响。由于高温少雨，福井县、新潟县和长野县等水稻产地严重缺水，水 稻长势受影响。丹波市农业协会的工作人员说，目前正值当地特产小豆的播种季节，已经有农户报告高 温缺水导致小豆不出芽。如果高温持续，可能严重影响收成。 先前高温纪录出现于2020年8月的静冈县浜松市和2018年7月的埼玉县熊谷市，均为41.1摄氏度。 日本气温多日来"高烧不退"，全国多地7月30日出现40摄氏度及以上高温，并创下高温新纪录。共同社 等日本媒体援引日本气象厅数据报道，7月30日这天，西部兵库 ...

北半球正值盛夏，多地正在经受高温炙烤。美国国家气象局7月30日对美国多个地区发布高温预警，超 1.4亿美国人受到影响。 29日，纽约拉瓜迪亚机场气温达到100华氏度（约37.8摄氏度），打破1949年创下的97华氏度的高温纪 录；佛罗里达州靠近墨西哥湾的海滨城市坦帕也在近日以100华氏度的气温打破当地高温历史纪录。气 象学家警告称，极端高温天气容易诱发健康问题，建议民众多饮水并待在较为凉爽的房间内。 近年来，美国乃至全球在夏季频繁出现极端高温天气，但是部分美国政客却频繁否认气候变化和全球变 暖。美国环境保护署在29日公布一项提案，拟撤销对于"温室气体排放危害公众健康和福祉"的科学认 定，准备为温室气体排放大开绿灯。对于美国的做法，一些外国游客给出了不同的答案。 德国游客尼古拉斯·托伊舍：全球变暖、气候危机，我知道美国人，尤其是美国政府不相信这些，但是 在我看来，情况越来越糟。极端高温绝对是我们在经历的气候变暖还有全球气候危机的一部分。 墨西哥游客塞萨尔·亚历杭德罗：极端高温肯定是因为全球变暖。我来自墨西哥城，那里的气温也高了 很多。空气又干又热，好像烧起来一样，不像是普通的热浪，空气热得像燃烧起来一样，这肯定 ...
