由于气候变化,印度的水利部门正面临着水资源日益变化和不可预测的问题。储水和配水基础设施不足,以及将气候适应能力纳入水管理政策不足,加剧了这一问题。IPCC第六次评估报告强调了这一点。主要威胁包括极端天气事件、气温上升、不稳定的季风和海平面上升,影响农业、工业、生态系统和整体水安全。
在南里奥格兰德州连续一周降雨量破纪录后,巴西正在经历一场环境和人道主义悲剧。洪水造成的死亡人数有几十人。失踪人数已超过100人。数百人受伤,数千人流离失所。近150万人受到影响。每一个关于生与死的故事都深深地打动着我们。匿名英雄不断涌现,他们的故事激励着我们。
极端的洪水和风暴、干旱和热浪等气候冲击对多个政策部门和系统具有复杂、相互关联和深远的影响。其他系统的冲击,如金融或健康危机,反过来也会影响气候挑战。对气候变化采用系统方法有助于决策者理解被单独处理的问题之间的联系,并在城市中提出跨部门、多学科的解决方案。本文提出了一个四管齐下的政策框架,以区分城市中经济、社会、环境和其他系统的不同要素,最大限度地利用共同利益,管理系统间的权衡,并在城市中建立系统的气候适应能力。报告概述了城市政策工作组和区域发展政策委员会对经合组织关于“在向低碳经济过渡中建立气候和经济复原力”的横向项目的贡献。
德国气象局(Deutscher Wetterdienst,DWD)发布了2023年夏季报告。PIK研究员Fred Hattermann评论道:“今年的降水量无法弥补过去几年积累的降水量不足。”
经过几十年的无所作为,世界终于开始解决如何支付帮助发展中国家社区应对气候危机影响所需的不断增加的成本。但这些社区将如何获得资金的问题仍然是一个悬而未决的问题。
March 20 marked the release of the final installment of the Intergovernmental Panel on Climate Change’s (IPCC) Sixth Assessment Report (AR6), an eight-year long undertaking from the world’s most authoritative scientific body on climate change. Drawing on the findings of 234 scientists on the physical science of climate change, 270 scientists on impacts, adaptation and vulnerability to climate change, and 278 scientists on climate change mitigation, this IPCC synthesis report provides the most comprehensive, best available scientific assessment of climate change. , It also makes for grim reading. Across nearly 8,000 pages, the AR6 details the devastating consequences of rising greenhouse gas (GHG) emissions around the world — the destruction of homes, the loss of livelihoods and the fragmentation of communities, for example — as well as the increasingly dangerous and irreversible risks should we fail to change course.
气候变化正在加剧全球自然灾害的数量、频率和持续时间,使减少灾害风险和建立抗灾能力成为未来最紧迫的挑战之一。传统决策者(如政府或科学家)与成为气候风险和抵御能力知识共同生产者的社区之间建立了伙伴关系。因此,与更传统的参与过程不同,通过合作制作,公民不仅得到咨询,而且通过他们的价值观、需求、观点和优先事项积极制定决策,以改善他们的现实。[8]第一个是使现有的洪水相关数据流可见,第二个是通过让公民参与在地方一级生成新类型的数据,第三个是将公民生成的数据与其他数据相结合。因此,该方法允许将自上而下的数据(专业中心产生的大数据)与自下而上的数据相结合,这些数据提供了有关社区物理和社会特征的基本信息。“合作生产和城市应对气候变化的能力”,同上,第1-2页。[16]联合国人居署,世界城市论坛第七届会议:发展中的城市公平——生命之城。WUF7报告,2015年3月,第54-55页,https://wuf.unhabitat.org/sites/default/files/2022-06/files/wuf7_report%20medellin%20colombia%202014.pdf.[17] Jon Coaffee、João Porto de Albuquerreque和Vangelis Pitidis,“合作生产中的风险和复原力管理”,同上,第545页。[18]David Satterthwaite等人,“在非正规住区建立应对气候变化的复原力”,《同一个地球》,第2卷,第2期(2020年2月21日),第143-156页,https://doi.org/10.1016/j.oneear.2020.02.002.[19] 格拉斯哥大学城市大数据中心网站:防水数据,https://www.ubdc.ac.uk/research/research-projects/urban-sustainability-participation/waterproofing-data.

When India’s federal government announced a public health lockdown on March 24, 2020 in response to the COVID-19 pandemic, it generated desperate scenes. Economic activity ground to a halt. Millions of migrant workers traveled back to their home states. , In the eastern Indian state of Odisha, it quickly became clear to officials that they were facing not only a public health emergency, but a potentially catastrophic unemployment and poverty crisis.
The planet has already warmed by 1.1 degrees C (2 degrees F) due to human-induced climate change. Millions of people today are facing the real-life consequences of higher temperatures, rising seas, fiercer storms and unpredictable rainfall. Rapidly reducing emissions is essential to limit temperature rise and secure a safer future for us all, as is making major investments to protect communities from severe impacts that will continue to worsen. , Yet collective efforts to curb greenhouse gas emissions and adapt are currently not enough to tackle the speed and scale of climate impacts, meaning that some losses and damages from climate change are inevitable. How countries handle these losses and damages has been a key issue at UN climate negotiations and beyond.
