Interesting article, nice reference to Who, but very very very very odd that the article makes the claim more than once that this is new idea, and it is not, indeed the very ideas that become the Silurians of Who fame were born out of a theory current at the time which was that dinosaurs had developed into an advanced civilisation and wiped themselves out in a nuclear war. |

In the article they mentioned the atmospheric conditions that caused the Silurians to go into hibernation but not what caused them. |

Which is what one can do when one is writing a work of pure fiction.  Being less flippant for a moment, the idea that we could be Civilisation 2.0 (or 3.0...) is fascinating but the empty SETI phonebook strongly suggests otherwise - I hope. If technological intelligences evolved so frequently that we had had two (or more) instances on our single planet over time, the radio quietness of the Universe would be very depressing indeed. It would imply that such civilisations all come and go very quickly. I believe that we are a one-off event in Earth history and (though by no means universally unique) members of a rare and privileged club of intelligent, civilisation-building species spread very thinly across space. As such, it is still more vital that we don't blow our one chance of making Earth a sentient, prospering world, a world which will be able to sustain intelligent life for aeons to come. |

The biggest issue I see is that the Ice Cap stores the particles that form a major sign of industrialisation.
Smoke from industry.
Dust from changes in the environment.
Stuff like that, but there’s no evidence of it. They can tell, from the ice when the great fire of Rome happened for example.
There ould be a record of pollution in the ice record. Even if the culture ended as 100% green,before then based on ALL the evidence we havevof cultures they ould have left a footprint in the ice.

Doesn't it depends on how old? - If an earlier civilisation was many 10My ago, aren't the ice caps new by comparison? One "disproof" I did think of is around the fossil fuel reserves, assuming any new civilisation would be heavy users of fossil fuels in their early industrial stages at least. The fossil fuel reserves we are using today have a finite life (even if usage is cut drastically) and are mostly very ancient, 150My to 400My old. Presumably any other civilisation would have been very much more recent than that and so if they used fossil fuels as we have done, the reserves we now use would not be there. I think. |

I thought about that as well. I watched a PBS special about weather and how they detected climate change. It is amazing what they can deduce from samples of ice, mud, even snail shells. What makes me a bit sad is watching these Doctor Who episodes from 30 or 40 years ago and we haven't made as much progress on these issues by now as I would have hoped. |

IIRC the really deep core Ice has preserved a Dinosaur Air. |
