概括
极端高温带来气候正义风险,特别是在城市冷却空间. 这项研究揭示了线性和面积冷却空间的重大不平等现象,突出了针对性干预措施的必要性,以确保公平地获得耐热战略.
科学领域:
- 城市规划和气候正义
- 环境健康和空间分析
- 公共卫生和社会生态系统.
背景情况:
- 极端高温事件加剧了弱势群体的健康风险,引发了严重的气候正义问题.
- 目前对与热量相关的不平等的评估往往缺乏细节细节,重点是全市范围的规模,而不是特定的户外冷却环境.
- 获得冷却空间的不平等不成比例地影响了某些城市地区和人口统计数据,强调需要以正义为导向的评估.
研究的目的:
- 开发和应用户外冷却空间的气候正义评估模型,将暴露-敏感性-适应能力 (VSD) 框架与正义的维度相结合.
- 分析特定城市区内线性 (如街道树木) 和面积 (如公园) 制冷空间的空间不平等.
- 确定高风险地区并对气候不公正的赤字进行分类,以告知有针对性的城市治理和公共卫生战略.
主要方法:
- 整合了VSD框架与分配,承认和程序性正义维度,以创建一个气候正义评估模型.
- 将户外冷却空间分为线性和面积类型,并使用多源数据 (遥感,街景,POI,人口统计) 来对州古鲁区进行分类.
- 采用权方法用于指标权重和K-means集群来识别和分类气候不公正空间类型.
主要成果:
- 发现线性 (37.18%) 和面积 (44.45%) 制冷空间的很大一部分面临着相当大的气候不公正风险.
- 气候不公正的高风险地区集中在密集的建筑区,老旧的社区和公共服务不足的边缘地区.
- 集群分析揭示了三个主要的赤字类别:分配性,认知性和系统性司法赤字,表明重叠的脆弱性和不均的适应能力.
结论:
- 该研究强调,迫切需要进行差异化城市干预,以减轻获得冷却资源的空间不平等.
- 建议的行动包括加强交通走廊的遮阳,改善老化社区的可访问性,并加强系统性赤字地区的适应性资源.
- 拟议的框架为以公平为重点的城市治理提供了证据基础,支持面对极端高温的弹性规划和公共卫生倡议.

01:17Design Example: Analyzing Capacity Contours for Flood Risk Assessment
268
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley.

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

01:21Masonry in Cold and Hot Weather Conditions
310
In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.
