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: 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: 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.

Description: This report highlights major weather stories that unfolded across the month of September 2020.

Description: Actuarial Weather Extremes: February 2021

Description: This report examines monthly and daily extremes from the Global Historical Climatology Network (GHCN) monthly and daily records and associated flooding, as well as extreme wind events in the Northeast U.S. and tornado and flooding events in the Southeast U.S. These signal the changeover from extreme winter conditions to volatile spring storm conditions which have been found in the U.S.

Description: The earth’s ecosystem appears to be leaving the 10,000-year Holocene epoch that featured a stable environment. For homo sapiens, this stability encouraged a move from hunter/gatherer to farming and urban lifestyles. The new period showcases climate risk, resulting in higher temperatures and more extreme weather. These conditions lead to greater exposures to properties and economies when events like hurricanes and wildfires occur.

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 looks at compound weather extreme events and their impacts, focusing on understanding how different weather and climate-related hazards interact. It discusses three types of compound events: temporally compounding, multivariate compounding, and spatially compounding events.
