Description: 2023 looks to already be the costliest year for insured severe thunderstorm damage in the U.S. surpassing the 2020 record of $44 billion, by August, and may very well surpass $50 billion for the full year. In addition to property damage, severe storms and hail have led to fatalities in the U.S. and the risks to populations in vulnerable structures seems to be worsening.

Description: This report provides results from a recently conducted study using the AIR Wildfire Model for the United States and available climate and climate change information to estimate how climate change may influence wildfire losses to U.S. property by mid-century. The climate change conditioned catalogs were used to evaluate climate change impacts (relative change in losses) to the AIR Worldwide US Industry Exposure Database, with all factors other than area burned held constant.

Description: The Society of Actuaries Research Institute’s new report examines how inland flood risk and loss may change across the U.S. in the future because of climate change. The AIR Inland Flood Model for the U.S. and the AIR Hurricane Model for the U.S. were used to evaluate how changes in flooding will impact insurable losses in the future.

Description: In the early morning of July 26, 2022, an extreme precipitation event hit St. Louis, leading to a new all-time record for daily precipitation and widespread flash flooding in the metro area, with one fatality reported so far. Government officials at the state, county, and city levels declared states of emergency, allowing affected residents and business to access assistance and resources. Several roads and Metrolink stations were submerged and impassable. Metrolink damage is estimated at $18-20 million, with some stations expected to be shut down for two weeks.

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: This report examines weather extremes for daily maximum temperature (TMAX) and severe drought conditions. The heat extremes were most impactful in the Western U.S. and Canada, and the severe drought conditions are a continuation and worsening of the most extreme condition statuses in the Western U.S.

Description: Discuss a comparison of the U.S. general and insured population mortality experience and how COVID-19 and non-COVID-19 excess deaths impacted the populations differently. Discover the population mortality experience in the UK with a focus on the recent emergence of excess deaths for non-COVID causes. The long-term implications on the insured population will also be explored. Wrap up with a discussion of different conditions of long COVID, including organ impairments.
