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: 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: Heavy Precipitation in the U.S. Southeast, and Dry Conditions in California This report highlights major weather stories that unfolded across the month of February 2020.

Description: The SOA Research Institute Catastrophe and Climate Strategic Research Program released a report that explores the shifting geography of Lyme Disease in the U.S. and beyond and some of the potential determinants of its spread. Lyme Disease is a well-known disease particularly in the eastern U.S., and it is also prevalent in other geographies. This report researches the complex relationship between climate variables and the spread of Lyme Disease in the United States.

Description: Actuarial Weather Extremes: November 2021 Extreme Precipitation, Drought, and Late Season Tornadoes This report examines weather conditions for precipitation, drought conditions, and late season tornadoes that are extreme in an historical context. Extreme Precipitation in the Pacific Northwest: Many Global Historical Climatology Network (GHCN) stations in Northwest Washington state and Southwest British Columbia had record November daily precipitation amounts on November 14 and 15, 2021 when looking back to 1960. During and after those dates, many U.S. Geological Survey (USGS) stream gage stations in Washington had readouts that were from Flood Stage to Major Flood Stage. Drought Conditions increase in Continental U.S. as Drought Moves East: Severe drought conditions in the Western U.S. dissipated somewhat, but in the Continental U.S. as a whole, the footprint where drought conditions exist has increased overall, and is driven primarily by increased drought in South-central and Middle Atlantic states. Late Season Tornado Activity: Comparing the historical database of tornado activity and the recent activity in the state of New York, of 24 November tornadoes reported in New York since 1950, nine occurred on November 13, 2021. These late season tornadoes are rare in New York, and November 2021 was exceptionally active for these storms.
