Here is a short elevator pitch video from NASA about global warming:
The interesting thing is that it talks about “old carbon”. It explains that the carbon stored in coal was stored there hundreds of millions of years before. And we are releasing it now.
It does not discuss the issue from the point of view of the fossil fuel involved. Humans are burning ancient trees. How would we feel if some alien species dug up all our graveyards and burned the bones for their energy needs?
Someone should write a novel about this.
