Climate Change
About Climate Change ...
Greenhouse gases are a natural part of the atmosphere. They absorb and re-radiate the Sun's warmth, and maintain the Earth's surface temperature at a level necessary to support life. The problem we now face is that human actions are increasing the concentrations of the gases that trap heat. This is contributing to a warming of the Earth's surface. (www.climatechange.gov.au).
It is widely accepted that this warming causes changes to the Earth’s climate, leading to dramatic environmental, economic and social impacts.
