Why Sequester CO2?

 

Carbon Dioxide (CO2) is a known and by far the most abundant greenhouse gas. It is widely believed that the addition of anthropogenic production to the natural production of CO2 is greater than the Earth's natural ability to buffer the concentration of CO2 in the atmosphere. This results in an average increase in the temperature of the atmosphere and oceans which causes changes in weather patterns. A controversial hypothesis states that the average rise in surface temperatures will eventually melt significant portions of the polar ice caps. This combined with the decrease in density of the ocean due to its increase in temperature will cause coastal flooding.

For these reasons, a number of developed countries including Canada have signed the Kyoto proto call which calls on it's participants to decrease CO2 production to below 1990 levels by 2012. Though part of this plan can be achieved through energy efficiency and renewable energy sources, sequestering CO2 will likely be the only way to fully meet the goals of the proto call.
