Correction: Ocean mass v atmospheric mass closer than what I wrote

It is a major and embarrassing goof.  Looks like I read "pounds" where it said "tons".  That's 3 orders of magnitude difference.

Still, the weight difference is significant.  Especially between carbon dioxide and water.

There is more likely than not far more water in the atmosphere than carbon dioxide.  Also, water is said to be a greenhouse gas and definitely has greater heat capacity than carbon dioxide.

Goes to show you how a bias can lead to mistakes.  I'll own up to mine.
