there've also been ice ages and warming ages due to various solar and orbital characteristics, but these haven't been associated with Co2 changes.
But if our temperature goes up a pip then its our fault for having coal power stations and driving ICE cars.
Have solar and orbital characteristics disappeared?
Has volcano activity ceased?
Have you thought for a moment that it's the solar activity that drives up the co2 levels and not the co2 levels that drives climate?
Look at the size of the sun, then look at the size of the earth and the imagine that 0.04% of that tiny speck of rock called earth is co2 and have a serious rethinks of what is affecting what.
