Climate change is a naturally occurring phenomenon.
However, its recent rate of change is cause for concern and increasing evidence points the finger at this being a result of human activity.
We appear to be influencing the planets key life support system in a manner that is unprecedented in the earth's history.
The Greenhouse Effect is the term used to describe the selective response of the atmosphere to different types of radiation. Incoming short wave radiation passes through unaltered, while returning long wave radiation is absorbed by so-called greenhouse gases. The ability of the greenhouse gases to prevent the passage of long wavelength radiation effectively traps the suns heat close to the earth. Gases responsible:
Mainly Carbon Dioxide (CO2)
