New York City Climate Projections: Extreme Events and Sea Level Rise

This report includes updated changes in extreme events (e.g., hot days, days with heavy rainfall, heat waves) for the 2030s, 2050s and 2080s; and sea level rise projections for the 2030s, 2050s, 2080s, 2100 and 2150 for the New York City region, based on those developed for the IPCC 6th Assessment report. The sea level rise projections are based on the CMIP6 models and SSP framework, and also incorporate advances in process understanding, improved and lengthened observational records, and improved ice-sheet modeling.

The New York City Panel on Climate Change (NPCC) started in 2009 and was codified in Local Law 42 of 2012 with a mandate to provide an authoritative and actionable source of scientific information on future climate change and its potential impacts.

The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body for assessing the science related to climate change.

本报告涵盖了2030年代、2050年代及2080年代极端事件（例如，高温天气、大雨之日、热浪）的最新变化；以及基于IPCC第六次评估报告所开发模型，对纽约市地区2030年代、2050年代、2080年代、2100年和2150年的海平面上升预测。海平面上升预测基于CMIP6模型和SSP框架，并融合了过程理解的进步、观测记录的改进与延长，以及冰盖模型的发展。纽约市气候变化委员会（NPCC）自2009年起成立，并于2012年通过地方法律42正式确立，其职责为提供权威且可操作的气候变迁及其潜在影响的科学信息来源。政府间气候变化专门委员会（IPCC）系联合国评估气候变化相关科学的机构。
