Most if not all of scientist who are considered "deniers" have been suggesting this (natural factors). Some for well over two decades, the problem is partially funding and how the scientist method works. Usually a small group of researchers comes up with an idea and it takes a while for others to validate the findings. For example oceans plays a significant role in the climate. J. Curry et al correlated this current temp pause to other natural cycles measured in the past. Latest paper by Trenberth who is biased toward AWG speculates the pause is now mainly due to the Pacific Decadal Oscillation.
Another factor coming into play is time scales, the sun spot activity will be the lowest observed in the past 100 years. To all scientist this will be an exciting time since it will be new physical processes to study and how that drives the climate.
In addition, the problem for the past 20 yrs is that research has been hunting for man made cause, essentially that's the charter for the IPCC. Unfortunately, it takes a while a hypothesis to run its course.
