In his most recent mailing (and probably on the GISS website), Hansen summarizes NASA's prediction about global temperatures in the near future (by popular request).
Summary: the Southern Oscillation and increasing GHGs continue to be, respectively, the dominant factors affecting interannual and decadal temperature change. Solar irradiance has a non-negligible effect on global temperature...Given our expectation of the next El Nino beginning in 2009 or 2010, it still seems likely that a new global temperature record will be set within the next 1-2 years, despite the moderate negative effect of the reduced solar irradiance.
Similarly, the Hadley Centre had previously predicted at least half of the years 2010-2015 will be hotter than 1998, the current record according to their data.
So we probably won't have to hear about this 'global cooling' and 'global warming has stopped' nonsense for too terribly much longer. Although I have no doubt the deniers will milk it as long as they can.
