No discussion about co2 and climate change is relevant or complete without discussing the role of ch4 (methane), a much more powerful greenhouse gas.

- XMPPwocky 8y agoRight- definitely when discussing anthropogenic issues. (Also worth considering sulfur aerosols and their cooling effect, and lots of other stuff too.) Historically, though- IIUC- atmospheric methane levels have varied less than CO2, at least after some clever organism figured out how to photosynthesize, so, with solar output controlled for, the biggest hunk of temperature changes can be explained by the CO2 concentration.
