12. Climate: Making Sense and Making Money

A droplet of air  The atmospheric bathtub  Flapping molecules  A tea-cozy for earth  What we can't model  Protecting climate at a profit  In God we trust; all others bring data  More than efficiency  Why nuclear power can't help  If Karnataka can do it  Almost everyone wins

From space, the earth is blue because it is covered mainly by water. However, were it not for certain trace gases in the atmosphere, the earth would be a frigid icy white, and life as we know it would not exist.
