The Global Warming Problem
The earths climate in its 4.5 Billion year history has naturally changed between very cold, and covered in ice, to very hot.
In the last 10,000 years however, the climate has stabilized, creating an ideal environment for humans.
But, over the past 50-100 years, increasing human activity (such as industry, agriculture, and transport) has begun to effect the natural climate balance. These activities are increasing the amount of greenhouse gases in our atmosphere and causing earth to heat up faster than ever before since humans have been on earth.
