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: The research provides a modeling framework for assessing the inundation risk of properties and their expected flood damages, thereby laying a foundation for flood insurance pricing. The researchers studied over 50 years of claims data from the National Flood Insurance Program with 2.5 million records and identify property characteristics that predict flood damages for inundated properties. The development of a private flood insurance market hinges on insurers’ ability to better understand and price flood risk. This research takes a closer look at flood risk modeling and flood insurance pricing.

Description: Climate change affects everyone. Proactive responses that look forward to anticipate future conditions will optimize infrastructure investments rather than dealing with the crisis as extreme events arrive. Cities can address local concerns utilizing a process that is repeatable in other jurisdictions.

Description: Integrated Assessment Models (IAM) combine scientific scenarios that project changes in greenhouse gas (GHG) levels, resulting in global temperature increases and meteorological volatility when GHG increases, with quantitative economic models expanding on an aligned narrative.

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

Description: On June 29, a weather system formed in the central Atlantic Ocean, off the coast of the Cabo Verde Islands. The system intensified as it traveled in a westerly direction across the Atlantic, achieving sufficient strength to be classified as a tropical storm on July 1, whereupon it was given the name “Elsa”.

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 highlights major weather stories that unfolded across the month of December 2019.

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.
