When I was a kid, people didn't have refrigerators. They used ice boxes which kept the food cold only until the ice melted. Think of the world as a big ice box. The polar ice caps and glaciers are rapidly melting due to the greenhouse effect of the accumulation of carbon dioxide in the atmosphere. When there are no more polar ice caps and glaciers to take up the heat, the world will get hotter and stay hotter.
It takes a lot of heat to melt ice. Based on the heat of fusion of water, 80 calories per gram, we can calculate that the same amount of heat necessary to melt the glaciers and polar ice caps will raise the temperature of twenty times that amount of water from 70 degrees Fahrenheit to 77 degrees Fahrenheit.
It took several hundred million years to extract the carbon dioxide from the atmosphere and store it as fossil fuels in the ground. Once in the atmosphere, it will take hundreds of millions of years to put it back in the ground. Maybe all those scientists are wrong and the politicians are right. But do you really want to play Russian Roulette with your children's future?
