Simon Aegerter states that all additional atmospheric carbon dioxide for the last 150 years or so is from fossil fuels, that it remains in the atmosphere for many decades and is the cause of the warming experienced over the same time. Eric Jelinski endorses Ed Berry's physics flow analysis and conclusions. This is an important endorsement.
