Not so much a civilization, it could more accurately be described as an outpost of a civilization, doomed by sudden climate change. Nonetheless, very interesting.

We will watch about twenty minutes of this video together, as it offers significant geological background information to the present global warming scenarios presented in a way that a layman can understand. A seemingly dry academic topic, the lecturer brings it to life, makes it enthralling and not without humor.56 mins - Dan Britt - Orbits and Ice Ages: The History of Climate - YouTube

Dan Britt's lecture reminded me of a climate scenario video I created (long before I saw Britt's video,) that I'd like to share with you. You may recall from his lecture that when India slammed into the Euro Asian continent, it created a massive global-wide carbon sink that diminished the biosphere to a point that it triggered increasingly unstable, larger ice ages. This video is based on the supposition that the Earth's biosphere - or Gaia as some may refer to it - is a coherent entity in which the sum of parts make up a living whole.
Taking it further I muse that, like microorganisms, the biosphere has fundamental tools for survival; base instincts on par with hormones . This thought arose from the fact that within a very short timespan of geologic history, no less than five different hominoid species evolved into exhibiting the most unusual behaviour of walking upright. It just seemed to me such a remarkable coincidence, so I extrapolated on this and took it a step further: What are we here for? Are we the Biosphere's Earth worms? Does this scenario have implications on a Universe scale?
