Climate Change Is Pushing Hailstorms Toward Earth’s Poles, Scientists Find

A new global shift in hailstorm patterns

A recent scientific study shows that climate change is not only making weather more extreme, but also changing where hailstorms occur. Researchers have found that hail activity is gradually moving toward higher latitudes as the planet warms, reshaping risk zones across the world.

Why hailstorms are changing location

Hail forms inside strong thunderstorms when powerful updrafts carry water droplets high into freezing parts of the atmosphere. There, the droplets freeze and grow into ice stones before falling to the ground.

Scientists explain that global warming is disrupting this process. Warmer air holds more moisture and energy, which can strengthen thunderstorms and increase updraft power. However, higher surface temperatures also make it harder for hailstones to survive their fall, increasing the chance that they melt before reaching the ground.

The poleward shift in hail risk

Because of these combined effects, hail is becoming less common in warmer regions near the equator. Even when hail forms, it often melts before reaching the surface.

In contrast, cooler regions at higher latitudes provide better survival conditions for hailstones. As a result, hail risk is increasing in areas such as:
Canada
Northern Europe
Southeastern Australia
New Zealand’s South Island

At the same time, some tropical and subtropical regions are expected to see fewer hail events over time.

Seasonal changes in hail activity

The study also suggests that hail risk is shifting by season in some regions. Hailstorms may become less frequent during warmer months but increase during cooler seasons. This could affect agriculture cycles, especially crops like wheat that are sensitive to storm damage at specific stages of growth.

Hailstorms may become less frequent but more destructive

Another key finding is that even where hail becomes less common, individual storms may grow more intense. Stronger thunderstorms fueled by warmer, moisture-rich air can allow hailstones to grow larger before falling.

This means fewer hail events in some areas, but potentially more damaging ones when they do occur.

What this means for the future

Scientists say these changes show that climate change is not just increasing extreme weather, but also redistributing it across the planet. Regions that rarely experienced hail in the past may face new risks, while traditional hail zones may see shifting patterns.

Understanding these changes will be important for agriculture, infrastructure planning, and disaster preparedness in the coming decades.
