7 1.1 Objectives The purpose of this handbook is to help airport practitioners assess the benefits, costs, and financial feasibility of infrastructure projects that are designed to improve resilience to the impacts of climate change and extreme weather events. This handbook presents up-todate methods for conducting benefit–cost and financial feasibility analyses that explicitly recognize risks and uncertainties that are inherent in long-term climate projections and their potential effects on long-lived airport infrastructure.

8 Climate Resilience and Benefit–Cost Analysis: A Handbook for Airports The methods and analyses presented here focus on two specific areas of climate change likely to affect airports: (1) the potential for extreme flooding events due to storm surge and sea level rise (SLR)

10 Climate Resilience and Benefit–Cost Analysis: A Handbook for Airports A number of sources emphasize the significance of differentiating between extensive or chronic events, which are less severe and more frequent weather events that nonetheless can cause significant damage, and intensive or acute events that happen less often but may cause substantial mortality. While the United Nations' Global Assessment Report notes that chronic events are increasing in frequency, economic cost, and mortality (United Nations 2015a)

Introduction 11 Although LHR made large investments in upgraded snow removal equipment after the event, most of the report's 14 recommendations were directed at planning, communications, coordination between stakeholders, and other noncapital investments aimed at improving LHR's ability to plan for and execute a resilient response to such an event. An initiative sponsored by the City of Boston called "Climate Ready Boston" produced a report that presents projections for climate scenarios related to sea level rise, coastal storms, extreme precipitation, and extreme temperatures out to the year 2100 (Climate Ready Boston 2016)
