I don't understand how the bubbles persist in space. Wouldn't their liquid boil off? Secondly: How do we know the ecological role of humans isn't to return CO2 to the atmosphere? Sounds crazy right? Except that's the fundamental activity of our species - finding stored CO2 and burning it. And this activity comes right at the end of a glacial long trend that is going to refreeze earth to the equator in the next 10,000 years. But then along comes a species that is genetically adapted to finding and releasing stored CO2 back into the atmosphere. Just saying, we need to be careful of the stories we tell ourselves.
