Great balls of… air

Two images of the day: above — the picture says it all. Doesn’t look like much, does it? [via Ecohustler, h/t @Revkin]. And below, a NASA photograph from the International Space Station showing what that thin skin of air looks like in situ. Note the large cumulonimbus clouds casting shadows, especially the one left of centre, which looks as though it’s bumped into the tropopause. [h/t In It For The Gold]
