Global warming may make hailstones bigger and significantly more destructive in the coming decades, according to a new study published in Nature. Researchers warn that climate change could reshape hailstorm behavior globally, increasing the damage potential of hail events by up to 42% by the end of the century.

The findings highlight a paradox: while warming may reduce small hail events, it could dramatically increase the size and destructive power of larger hailstones.

What the Study Found

A major study by scientists from Peking University shows that hailstorms are becoming more intense under climate change conditions. Using climate simulations and real-world storm data, researchers found that hail-related damage could rise significantly in future decades.

Key findings include:

• Global hailstorm damage potential may increase by 36.5% to 42.1% by the late 21st century
• The frequency of large hailstones (≥30 mm) may rise by 37.9% to 51.8%
• Smaller hailstones (<30 mm) may decline by 4.2% to 12.3%
• Results based on analysis of 14,000+ real hailstorms (2014–2021)

These results strongly support concerns that global warming may make hailstones bigger and more dangerous, even if total hail frequency declines.

Severe Hailstorm Event Highlights Real-World Risk

A striking real-world example supporting the findings of the study comes from Springfield, Missouri (USA), where a severe hailstorm recently caused widespread destruction. The event saw hailstones reportedly reaching the size of baseballs and grapefruits, turning an extreme weather event into a major urban disaster.

According to reports, the storm caused:

• Widespread damage to residential and commercial buildings
• Severe destruction of parked and moving vehicles
• Multiple injuries among residents due to falling hail
• Significant disruption to local infrastructure and transport systems

This event underscores the study’s warning that global warming may make hailstones bigger and more dangerous, as warmer atmospheric conditions allow larger hailstones to survive the melting layer and reach the ground with destructive force.

How Climate Change Makes Hail Bigger

Scientists explain that warming temperatures change cloud dynamics in two opposite ways, leading to larger hail formation. Warmer air holds more moisture, which provides more water for hailstones to grow inside storm clouds. At the same time, a deeper warm atmospheric layer near the ground means smaller hail often melts before reaching the surface.

However, larger hailstones survive this melting layer and reach the ground intact, making storms more destructive.

• Increased atmospheric moisture = more hail growth material
• Thicker warm air layer = smaller hail melts before landing
• Stronger storm updrafts = longer hail growth time

Lead researcher Qinghong Zhang noted that smaller hailstones often disappear as rain, while larger ones survive and strike the surface with much greater force.

Regional Differences in Hail Risk

The impact of global warming may make hailstones bigger, but this will not be uniform across the world. Some regions are expected to face higher risks, while others may see fewer hail events overall.

• Higher-latitude regions may see more frequent large hailstorms
• Tropical regions may experience a decline in hail frequency
• Stronger warming in polar zones enhances storm updraft intensity
• Increased humidity boosts hail growth in mid-latitude storm systems

The study suggests that rising temperatures strengthen vertical wind systems in storm clouds, allowing hailstones to grow larger before falling.

Impact on India and South Asia

The study warns that South Asia, including India, could also be affected by changes in hail patterns. Regions like North India, Punjab, Haryana, and Rajasthan already experience seasonal hailstorms, and these areas may see an increase in large hail events in the future.

Potential impacts include:

• Increased crop damage during pre-monsoon storms
• Higher risk to livestock and rural infrastructure
• Greater uncertainty in seasonal weather patterns
• Mixed regional effects, with some southern areas seeing fewer hail events

Agricultural systems are particularly vulnerable, as even short hailstorms can destroy entire harvests in minutes.

Damage to Cities and Infrastructure

Urban areas are also at growing risk if global warming makes hailstones bigger, becoming a long-term trend. Large hailstones can cause severe damage in minutes, affecting both public and private infrastructure.

• Vehicles and parked cars face heavy denting and breakage
• Solar panels can crack under high-impact hail
• Roofs and buildings suffer structural damage
• Insurance claims and repair costs rise sharply

Final Outlook

The study provides a clear warning: Global warming may make hailstones bigger, transforming hailstorms into more destructive climate hazards.

While the number of small hail events may decline, the intensity and size of extreme hailstorms are expected to rise significantly. Scientists stress that reducing global emissions is essential to limiting future hail-related damage to cities, agriculture, and infrastructure worldwide.

Future Risk Outlook

Scientists emphasize that continued warming will likely intensify hail-related damage globally. If emissions remain high, hailstorms may become less frequent but far more destructive.

This shift suggests a world where hail becomes less common but far more damaging when it occurs.

FAQs

1. How can global warming make hailstones bigger?

Warmer air holds more moisture and strengthens storm updrafts, allowing hailstones to grow larger inside clouds before falling to the ground.

2. Does climate change increase or decrease hailstorms?

Climate change may reduce the number of small hail events, but it can increase the intensity and size of larger hailstones, making storms more destructive.

3. Why are bigger hailstones more dangerous?

Larger hailstones survive the warm atmospheric layer without melting and hit the ground with greater force, causing more damage to buildings, vehicles, crops, and people.
