The main issue we seek in the global warming debate is the truth. The only question in this debate is “Does human emission of CO2 causes global warming?”
One way to answer this question is to verify the IPCC projections for the mean global temperature anomaly that states [1]
For the next two decades, a warming of about 0.2°C per decade is projected for a range of SRES emission scenarios.
This result can be verified by comparing it with actual measurement (hadcrut3 [2]) as shown in the chart above, which shows IPCC projection is incorrect. Actually, the observed mean global temperatures anomalies are even less than the projections with emission commitment held constant at year 2000 values, as shown by the orange curve in the above chart.
