概括
旨在实现公平的气候政策在使用广的地理区域时可能会失败. 一项研究表明,专注于"处境不利的社区"并不能降低脆弱家庭的洪水风险,而不是针对家庭的融资.
科学领域:
- 环境政策分析 环境政策分析
- 适应气候变化 适应气候变化
- 环境正义中的社会公平
背景情况:
- 气候政策越来越多地旨在改善公平,通常是通过将资源转移到"处境不利"的地区.
- 美国的"正义40倡议"要求联邦计划优先投资"处于不利地位"的人口普查区.
- 在基于个人的股权定义和空间粗的政策实施之间存在差异.
研究的目的:
- 评估"正义40"倡议在实现个人气候适应成果中的公平性方面的空间粗方法的有效性.
- 为了比较Justice40方法与家庭基于风险的融资策略,用于气候适应投资.
主要方法:
- 一个市镇的案例研究分析,该市面临重复的洪水和有限的资源.
- 联邦应急管理局对"正义40"倡议的实施情况的评估.
- 家庭基于风险负担的融资规则与正义40标准的发展和比较.
主要成果:
- 在案例研究中,Justice40倡议的实施并没有降低负担最大的家庭的洪水风险,也没有降低风险不平等.
- 正义40的实施导致净成本,未能有效地促进家庭洪水风险结果的公平.
- 基于家庭风险负担的融资规则被证明是具有成本效益的,针对负担较大的家庭,减少不平等,并产生显著的净收益.
结论:
- 在空间上粗的"处境不利的社区"指标有可能错误地识别气候风险,并且可能对实现气候投资公平承诺无效.
- 政策必须使空间分析尺度与气候风险和负担的分布保持一致,以有效地促进公平.
- 家庭级数据和风险负担定位为气候适应融资提供了更公平,更具成本效益的方法.

Global Climate Change
24.2K
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.

What is Climate?
18.3K
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.

Adaptations that Reduce Water Loss
25.1K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Energy Budgets
9.2K
Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
40
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. The engineers...
