The major environmental challenge of our time is framed in terms of what happens in our atmosphere, and specifically what are called “greenhouse gases”. But what is an atmosphere, and how does it behave? Does the atmosphere vary across the world, and what enters and leaves it normally? This lecture will explore how humanity has taken some things from the air and put other things into it, what the effects have been, and what this means for our future.
