It could increase the amount of rainfall along with the hotter temperatures. These conditions would mean a longer growing season, and that would mean increased crop yields for the farmers in the area. Destruction of the ozone layer lets more ultraviolet rays reach the earth's surface. This is dangerous to life on earth since overexposure to harmful ultraviolet rays can cause sunburn in humans and lead to many other problems for plant and animal life. A hailstone starts off as a small chunk of ice.
Winds blow the ice through parts of the thunderstorm where the cloud water is supercooled .
What is special about supercooled cloud water is that it exists as a liquid even though the temperature is below freezing. As the hailstone travels through the supercooled water drops, the liquid water freezes onto it, making the hailstone grow larger.
