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: The purpose of the paper is to facilitate understanding of the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD) and its ramifications on actuarial work.

Description: This report will endeavor to introduce the reader to some of the known and developing environmental risks that impact the business of insurance, with a specific focus on North American risks.

Description: The unprecedented losses associated with recent wildfires are yet another call to insurers to understand how climate change is impacting the landscape of fire hazards. In this report, to further advance understanding of relationship between fire hazard and climate change, for both academic and practitioner communities, we review emerging evidence showing that policies surrounding tree planting are increasingly important for fire hazard insurance. Furthermore, we discuss relevant risk factors and potential mechanisms when accounting for these policies.

Description: Climate change has the potential to wreak havoc on ecosystems worldwide. One anticipated repercussion is the change in suitable habitats of vectors, such as mosquitos and ticks, who can transmit serious and even life-threatening diseases to humans. In this report, we outline major vector-borne diseases, discuss their symptoms and treatment costs, and present the relevant research regarding their evolving spatial patterns due to climate change.
