This result is based on short term observations of temperature changes while CO2 concentrations were approximately constant, so they only hold true over periods when CO2 does not change much. (friendsofscience.org)

c) If skeptics are doing it right and changes should be considered over 100 years, then one simply can not take much shorter term observations and derive from them that the 100 - year forecast is right (i.e. «there has been minimal temperature change overall from 1998 till 2010, so we are right to predict that temperature will not change over 100 years»).
