The argument here is this: scientists have each identified, in isolation, various factors that work opposite global warming, and have determined, in isolation, that these factors, considered individually, cannot balance out global warming. In video 3, the author identifies natural phenomena that he says climate models have failed to factor in, such that the effect is that they far too heavily weigh the impact of humans on the climate. Unfortunately, the video author makes a failure common to many climate change skeptics. First, the author failed to make a positive claim with justification that yes, indeed, the cooling phenomena identified in isolation when considered holistically counteracts warming. Next, he fails to propose a model that provides a cause of the extraordinary current increasing trend. Considering the lack of a positive model, I would still have to accept the IPCC findings as the most plausible model.
