According to the authors, "A network of 171 individual blogs is identified, with three blogs in particular found to be the most central: Climate Audit, JoNova and Watts Up With That. These blogs predominantly focus on the scientific element of the climate debate, providing either a direct scientifically-based challenge to mainstream climate science, or a critique of the conduct of the climate science system. This overt scientific framing, as opposed to explicitly highlighting differences in values, politics, or ideological worldview, appears to be an important contributory factor in the positioning of the most central blogs."
The abstract appears to be complementary to the climate skeptic blogosphere as science-based sources of "expertise", "scientific knowledge production", and "reinterpretation", as opposed to prior papers characterization of climate skeptic blogs as "deniers" of climate change and climate science.
