All plant life depends on absorbing CO2 from the atmosphere, while exuding oxygen as a photosynthetic byproduct. All aerobic life on land depends on the oxygen produced by plants. Additional CO2 in the atmosphere would encourage more healthy plant growth. Carbon dioxide, water and methane are culprits in the greenhouse effect. Large quantities of methane are released from marshes, swamps and other natural source.
Population alone contributes to the global warming.
It's increased sixfold, from one billion in 1850 to six billion today. Every one of these people exhales CO2 and water vapour with every breath. I was anxious for details of a practical application in Alberta. I was a little less pleased to find what appear to be liberal use of journalistic license and an inaccuracy. The story also says that combustion is so close to perfect that you could stay around and breathe the exhaust forever.
