"University of Alabama climatologists John Christy and Roy Spencer have released their monthly statistics on global warming trends detected by National Oceanic and Atmospheric Agency satellites. In the press release accompanying the data, Christy notes that the rise in global average temperatures has been largely stalled since the big El Nino event in 1998"
"Based on the empirical data gathered by the NOAA satellites, Christy remains skeptical of climate models that predict future catastrophic warming:

There are so many natural variations and oscillations that we just cant say that this looks like a human fingerprint on the lower atmospheres climate, said Christy. We know that some human activities must have an impact on the climate system. But one has considerable difficulty in looking at what has happened over the past 34 years and reasonably or with scientific accuracy saying whether or by how much the change has been natural or caused by us.
Changes of this amount over these time scales could be essentially natural. Such a hypothesis has not been proven false. Scientists would love to have these types of measurements from the past 2,000 years to see to what extent Mother Nature can cause changes over decades on her own. But the thorny question of how sensitive the climate is to extra greenhouse gases we are putting into the atmosphere is still up in the air.
