Dr. Roy Spencer on Global Warming, 'No one knows'

SPENCER: There has been no increase in "superstorms" or tornadoes, by any objective long-term measure. It is an urban myth. Sandy-class storms occur every year...they just don't happen to hit high population density areas. But sea levels have indeed increased, which probably is a sign of warming. But sea levels were rising long before we could have been to blame, since well before 1900. So, once again, it is difficult to attribute the current rate of rise, which is very slow, to humans when we don't know how much of the rise is natural...SPENCER: The consensus is only that humans are contributing to warming...even I would probably agree with such an innocuous statement. But even if a majority of scientists think manmade global warming is a serious problem, only a very small number of those scientists know enough about such a detailed subject to have an informed opinion on the subject. Only a few of us actively working on questions "how sensitive is the climate system?" know the dirty details of this business and how much uncertainty there is. Most climate researchers simply assume recent warming is manmade, but human causation is only one possible explanation out of several.
