CO2 in readily available oil almost surely will end up in the atmosphere, it is only a question of when, and when does not matter much, given its long lifetime. CO2 in coal does not need to be released to the atmosphere, but if it is, it cannot be recovered and will make disastrous climate change a near certainty." Can anybody point me to some info on this concept. Why would it matter what the source of the CO2 is? Thanks I’ve never heard before the argument that Jim Hansen makes above:

Not so, with coal. He is saying oil is so useful and versatile, it will all get burned eventually. Not so, with coal.
