There is a beautifully written article on Eco Preservation Society on the basics of Climate science. Much of the information on Climate Change out there isn't very simple and easy to understand. So here are some of the basics on what we know and what we don't know about climate change.

- The Earth and the moon receive the same amount of solar radiation

- The average Temperature on the earth is 15 deg C while it is -153 deg C on the moon. Why is this?

- The Atmosphere of the earth is responsible for this temperature difference. What is the earth's atmosphere made of?

- 99% of the earth's atmosphere is composed of Nitrogen and Oxygen that do not have any impact on its temperature. Greenhouse Gases, like CO2, make up the remaining 1% of the atmosphere and are the reason behind the warmer temperature experienced on earth

- While we know for a fact that Greenhouse Gases make the earth warmer and that human beings are causing the concentration of greenhouse gases in the atmosphere to increase, (the concentration of greenhouse gases has been increasing steadily since the start of the industrial revolution) what we aren't sure of is exactly how much of the warming is natural or not man-made. All the recent papers published by the scientific community places a high probability on the warming being man-made, but it isn't 100%
