This natural effect is responsible for the comfortable living conditions on earth, with a mean global temperature of 15 ºC. Without GHGs the mean temperature would be approximately 30 ºC lower.

Causes of Climate Change
Cambodia
Increase in Green House Gases mainly due to human activities such as:
• • • Burning fossil fuels (coal, oil, natural gas) to generate energy Land use change and deforestation Agricultural activities or change in land use such as rice paddies, livestock, waste dumps, and domestic sewage Usage of chemical fertilizers or pesticides
•
This leads to Greenhouse Effect – increase in GHGs in atmosphere preventing heat to escape into the space, keeping the earth warmer
