Description: The document is a quarterly global warming report by the Society of Actuaries Research Institute, providing statistical summaries of global warming trends using ERA5 data. The report compares temperature data from different time periods and highlights warming trends across air and sea-surface temperatures.

Description: There is value in a framework that allows a smooth transition from a qualitative assessment to a quantitative analysis as entities mature in their understanding of climate risk. In this report, a case study on climate change impact on home prices is used to illustrate a Bayesian network iterative approach to building a model for scenario analysis.

Description: On March 5, 2022, an EF-4 tornado hit Iowa and caused 6 fatalities, according to preliminary reports.1 The supercell thunderstorm that produced the destructive tornado also produced damaging wind and hail events. According to the National Weather Service, this tornado was the first EF-4 tornado in Iowa since 2013 and was the second longest tornado path since 1980, with a path length of 69.5 miles.

Description: On May 20, 2022, an EF-3 tornado hit Gaylord, Michigan and caused 2 fatalities and 44 injuries, according to the National Weather Service Damage Survey [2]. The supercell thunderstorm that produced the destructive tornado also produced damaging wind and hail up to 3 inches in diameter [3]. According to data from the National Center for Environmental Information, this tornado was the first EF-3+ tornado in Michigan since 2012 and first EF-3+ tornado in Michigan in May since 1991 [1].

Description: This report series identifies and examines weather extremes in North America and beyond. Using data from the National Oceanic and Atmospheric Administration (NOAA), National Centers for Environmental Information (NCEI), NOAA Global Historical Climatology Network (GHCN), United States Geological Survey (USGS), and United States Department of Agriculture (USDA) among others; the reports identify and summarize unusual or extreme single-day or multi-day weather events which are significant in an historical context. The most recent report covers the tremendous scale of Hurricane Ian as it hit Florida and the geographic range of the perils associated with the hurricane.

Description: In this short report, we summarize Dorian’s rainfall totals as measured via data from the Global Historical Climatology Network3 (GHCN).

Description: This report highlights three major weather stories that unfolded across the month of June: • A heat wave gripped much of Europe in the last week of June • An extreme wind event known as a “derecho” swept across a 1000-mile path in the United States (U.S.) on June 21, beginning in Nebraska and culminating in South Carolina • Widespread flooding continues throughout the Central U.S, with a significant impact on farming

Description: Supporting excel file for November 2020 weather extremes.

Description: This report evaluates the impact and evolution of societal risk management due to projected future changes in frequency, severity, and variety of weather-related catastrophes.
