HailstoneThe largest ever hailstone weighed over 1kg and fell in Bangladesh in 1986.
RainAccording to samplings taken by the National Oceanic Atmospheric Administration, Rain water in large areas of the United States has become from a hundred to a thousand times more acidic than it was in the era before fossil fuels. Much of the Rain that falls in various parts of the country is almost as acidic as vinegar, reports the survey. The rain in turn affects lakes across the country. In the Adirondack State Park in New York, it is reported that two hundred lakes are now so acidic that they can no longer support fish life. Many scientists believe that the 10 percent decrease in the growth of forests across the northeastern United States is due to the same cause.
