It depends where you start your regression, but the last three charts from your link show a leveling off and a decline for the last two to three years. Roy Spencer, Principal Research Scientist at the University of Alabama, when I talked to him last year did not claim a decline as does Lord Monckton but essentially no net global warming since 1998. The point is we have not had the runaway greenhouse effect projected by many in 1998. The recent leveling off and decline does correspond with the current solar minimum. The NASA data also shows this see http://data.giss.nasa.gov/gistemp/2008/ A recent article in Physics Today estimates that the Sun could account for as much as 69% of the increase in Earth's average temperature.

May I suggest this link for a fuller view of the meaning of the good Lord's graph, and the underlying data? http://jhubert.livejournal.com/181274.html Quoting "Don J. Colton" <djcolton@piol.com>:
By all global measures we have had no global warming for the last seven years. See http://icecap.us/images/uploads/monckton-global_warming_has_stopped.pdf
