But what is laughable in the Discovery link I posted is that they expand on the theory in your posted link and blame industrialized society as the cause of the climate change that leads to the extinction. You know - to make us feel bad for having an industrial society and for just being human.

typical liberal journalism, they didn't even read the original paper.
from there:
"The existence of life on Earth today might have more to do with the unusually rapid biological evolution of effective niche construction and Gaian regulation in the first billion years. Habitability and habitable zones would then not only be a passive abiotic property of stellar and planetary physics and chemistry (such as stellar luminosity, initial water content, and decreasing bombardment rate) but would also be a result of early life’s ability to influence initially abiotic geochemical cycles and turn them into the life-mediated biogeochemical cycles that we are familiar with on the current Earth (Lenton,
1998; Lenton et al., 2004; Schneider, 2004; Falkowski et al., 2008; Kump et al., 2009).
Without rapid evolution of Gaian regulation, early extinction would be the most common fate of planetary life. Even if the emergence of life is a common feature of wet rocky planets throughout the Universe, the Gaian bottleneck model suggests that inhabited Earth-like planets would be rare."
