The Impact of Climate Change on Hailstorms: Expect Bigger Hail and Higher Costs
As global temperatures rise, the world is likely to experience more severe hailstorms with larger hailstones. A recent study suggests that hailstones measuring 1.5 inches or larger will become more common, driven by stronger updrafts in thunderstorms due to increased atmospheric instability. These hailstones pose a significant financial risk, particularly in storm-prone regions.
Hail already causes more damage annually in the U.S. than hurricanes or floods, with thunderstorms responsible for over $60 billion in economic losses this year alone. Large hailstones, which fall at speeds of up to 100 mph, can cause significant damage to property, vehicles, and agriculture, leading to higher insurance claims.
The research warns that as climate change progresses, insurance premiums may continue to rise due to the increasing frequency of severe hailstorms. Scientists are using advanced weather modeling to better predict these storms and minimize damage, but understanding the dynamics of hail formation remains a challenge.
With larger hailstones becoming more common, communities and industries must adapt to the growing risks posed by this overlooked weather hazard.
As climate change intensifies, larger and more damaging hailstones are expected to become more common. A recent study by Northern Illinois University researchers projects a significant rise in hailstones measuring 1.5 inches or more, depending on future greenhouse gas emissions. These larger hailstones pose an increasing financial risk, particularly in regions prone to severe storms.
Hail is generated by strong updrafts in thunderstorms, which allow hailstones to accumulate ice before falling to the ground. As the planet warms, increased atmospheric instability leads to stronger updrafts, enabling the formation of larger hailstones. According to Victor Gensini, lead author of the study, stronger updrafts act like a hair dryer holding a ping pong ball in the air—only now, those updrafts will need to support much larger objects like baseballs or grapefruits.
Hail is already one of the costliest weather hazards in the U.S., accounting for between 50% and 80% of thunderstorm-related insurance claims. In 2023 alone, thunderstorm-related economic losses in the U.S. totaled around $61 billion, with hail contributing between $31 billion and $49 billion.
Advances in climate and weather modeling have allowed researchers to create detailed simulations of thunderstorms and their microphysics, including hail formation. Although fewer days of hail are predicted for some regions, larger and more destructive hailstones are expected to become more frequent.
These developments are pushing the insurance industry to reassess risk models and driving up premiums. As climate change worsens, understanding hailstorm dynamics becomes crucial for creating more accurate forecasts and minimizing damage.
Frequently Asked Questions (FAQs)
Q: Why is hail becoming more dangerous as the climate warms?
A: Climate change increases atmospheric instability, leading to stronger updrafts in thunderstorms, which allow hailstones to grow larger before falling. This results in more destructive hailstorms.
Q: How does climate change affect hailstorm frequency and intensity?
A: While some regions may see fewer hailstorms, the hailstones that do form are expected to be larger and more damaging. A study projects a 15% to 75% increase in large hailstones, depending on greenhouse gas emissions.
Q: How does hail damage compare to other weather hazards?
A: In 2023, hail caused more damage in the U.S. than hurricanes or floods, contributing between $31 billion and $49 billion in economic losses. Hailstorms also account for the majority of thunderstorm-related insurance claims.
Q: What advancements are helping scientists study hailstorms?
A: Advances in radar and weather modeling now allow researchers to simulate thunderstorms in detail, including hail formation and size. These tools provide better predictions for hailstorm behavior as climate change intensifies.
Q: What are the insurance implications of larger hailstones?
A: As hailstones grow larger, they increase the risk of property damage, driving up insurance premiums. The insurance industry is reassessing risk models to account for these changes.
