Average global temperature rose 0.6°C during the 20th Century, and is projected to rise between 1.5 and 5.4°C by the year 2100. Anthropogenic greenhouse gas (GHG) emissions are widely believed to be the dominant causal factor for these increasing temperatures, which lead to other related changes in climate, including increases in sea level, melting of polar ice caps, changes in global air and oceanic circulation patterns, and changes in the hydrological cycle. Climate change is expected to affect all aspects of life for a wide range of human, animal and plant populations around the world. Annual emission of CO₂, one of the GHG, in Israel is 11 tons per person, similar to other developed countries...
