High-Impact Weather and Climate Events

High-impact events cause the majority of societal costs related to weather and climate. They provoke societal responses that can either enhance or detract from long-term adaptation to climate risk. In 2015, WWA began a new research focus on extremes that is designed to place high-impact events in the context of historical climate variability and projected climate change, assess how the risk of these events varies over time and space, and examine how high-impact events interact with place-based vulnerability.

The first activities in this new research theme have been to build a database of 160+ historical high-impact weather and climate events in the three-state region, and to generate a complementary set of regional event maps showing how risk varies seasonally across the region for different types of weather and climate events.

All CPI-Adjusted Damage costs are 2022 values, calculated from: https://www.usinflationcalculator.com/. CPI-Adjusted Damage costs are unavailable before the year 1913.

Note: The High-Impact Events Database is currently being updated with more features. Stay tuned.
