We know from industrial production records approximately how much carbon we have brought up from underground and injected into the atmosphere by burning since the industrial revolution.
We know that the observed rise in atmospheric and oceanic CO2 is approximately equal to what we have dug/pumped up and burned.
We know from straightforward engineering physics that that much CO2 added to the atmosphere will result in about 1.5 watt/sq. meter reduction in the heat the planet looses to space.
The question is - if you feel that global warming is not occurring, what mechanism are you proposing to offset the known forcing of that much CO2?

For Gaby: the second "assumption " is 50 years of the most meticulous field experimental meas;urement ever done - Google "Keeling",.
The third is not an assumption, it's engineering math, the same stuff gets used to come up with practical numbers like space-station cooling requirements.

Of the answers given, all bu one supports the evidence for anthropogenic global warming. The single anti stated that temperature varied without human intervention, gave no mechanism. The number of questions on Y Answers deriding global warming gives the appearance of a much larger crowd. Asking for proof, or even a hypothesis, thins their ranks remarkably.
