Probably due to the fact that c02 forcing has become more dominant relative to solar forcing recently as the concentration has increased, which makes sense.

As other studies have said:

Kelly 1992: " even with optimized solar forcing, most of the recent warming trend is explained by greenhouse forcing".

Laut 1998: "the solar hypothesis—instead of contradicting—appears to support the assumption of a significant warming due to human activities".

Damon 1999 found that the sunspot-temperature correlation corresponds to an estimated 25% of global warming to 1980 and 15% to 1997.

Benestad 2005: "There have been speculations about an association between the solar cycle length and Earth's climate, however, the solar cycle length analysis does not follow Earth's global mean surface temperature. A further comparison with the monthly sunspot number, cosmic galactic rays and 10.7 cm absolute radio flux since 1950 gives no indication of a systematic trend in the level of solar activity that can explain the most recent global warming".

Good list of wankers.
