Some actions intended to adapt to climate change may do more harm than good, especially when they consume energy, making it more difficult to shift to decarbonized energy, or when, in meeting the needs of one group of people, they increase the vulnerability of others. Heat wave risk provides a typical example: air conditioning (AC) equipment may trigger large energy consumption and worsen outdoor heat stress. Alternative adaptation strategies exist, but it is not clear whether they can prevent the massive use of AC. Here, with an interdisciplinary modeling platform, taking Paris as a case study, we provide a first quantified analysis of the efficiency of adaptation strategies (large scale urban greening, building insulation policy, and generalized behavioral changes in AC use) in reducing future potential AC need. We find that even ambitious strategies do not appear sufficient to totally replace AC and ensure thermal comfort, under a median climate change scenario. They can, how...

巴黎早日适应热浪并减少空调能耗

旨在适应气候变化的某些行动弊大于利,特别是当它们消耗能源,使向脱碳能源的转化更加困难,或者在满足一组人的需求而又增加其他人的脆弱性时。热浪危险就是一个典型的例子:空调(AC)设备可能会触发大量能耗并加剧室外热应力。存在替代的适应策略,但是尚不清楚它们是否可以防止大量使用交流电。在这里,我们以跨学科的建模平台为例,以巴黎为例,对减少未来潜在交流电的适应策略(大规模城市绿化,建筑隔热政策和广义行为变化)的效率进行了首次量化分析。需要。我们发现,即使在中等气候变化的情况下,即使是雄心勃勃的策略也似乎不足以完全替代空调并确保热舒适性。他们可以,怎么...
