I noticed that they didn't provide a citation for that statement, or the statement about "the more sustainable its practices, the less geological impact it would have". I'm not disputing them, but it did cause me to stop and ponder a bit. If we end up spreading solar panels all over our deserts, and wind farms over our continental shelves, will that be less detectable? Especially since there appears to be natural causes for large changes in atmospheric carbon (volcanoes hitting large oil deposits seems to be the thing they propose for this).
