One of the main culprits in global warming is carbon dioxide. There’s too much of it. It’s churned out by cars and cities and planes and boats by the boatload, all at the same time that we’re removing the trees that would gladly take it. So the solution it seems is to simply remove excess carbon dioxide from the atmosphere. Magic.
The various layers of Earth’s atmosphere are in a constant state of expansion and contraction, but last week, NASA announced that it was at a loss to explain why a huge section of the thermosphere collapsed into almost nothing. Oops.
