UNDERSTANDING GLOBAL WARMING
To understand Global Warming, you have to know about the Greenhouse Effect, climate, and pollution.
The Greenhouse Effect is the phenomena where gases
in our atmosphere trap heat from the Sun and keep the Earth warm.
When operating naturally, the Greenhouse Effect
keeps Earth's climate relatively stable.
Climate is an average measurement of weather over a period of time. We know Earth's climate has changed slowly over the millions of years of recorded history. However, measurements from the last 100 years show that Earth's temperature has gone up by 1 degree Fahrenheit.
