It's hard to imagine how things will be in 20 years. What will our generation say to its children? How will it explain the death of victims from events like Hurricane Katrina and the Indonesian tsunami? Will it be able to say it was because of global warming?Tor Lacy explains that global warming always happens. That global warming is a process that happened on earth even before man was around.
The way it works it works is that the sun heats up the earth through energy. The atmosphere acts like a layer that bounces back some of that energy out and absorbs energy in, so that the earth can remain at a comfortable temperature. Although the earth's temperature fluctuates, Lacy says that, "the temperature of the earth is rising at an unnatural rate. (And that) it is not normal." There are certain gasses in the earth, specifically carbon dioxide, that traps heat that's normally released by earth. With more greenhouse emissions being released into the atmosphere that layer is beginning to thicken and less heat is being bounced back out into space. Therefore, causing the earth's temperature to rise.
