It is apparent that there is no letup in the steep global warming trend of the past 30 years (see 5-year mean curve in Figure 1a).
Data @ NASA GISS: GISS Surface Temperature Analysis: 2007 Summation So all of a sudden, solar cycles and and other natural variations have significant effects on year to year temperature change?? You don't say....
If these factors are all-of-the-sudden important variables in determining climate, then increasing CO2 concentrations must have
even less to do with the temperature increases we saw in the 20th century. You can't have it both ways.
