@pschwede Actually ive seen this chart many times. So what about this chart do you feel debunks climate change? TIt shows pretty clearly to me the huge spike that only developed after the industrial revolution. You can see rather clearly around 1900 the spike sky rockets which is around the same time CO2 emissions sky rocketed... Where can you show me a natural spike that did NOT coincide with CO2 emissions though. That is the point your trying to debunk isnt it? Not seeing that here.
