I love Kim Stanley Robinson’s books, and am reading (in some case re-reading) his books in order. At some point, I’m going to get to Green Earth, but since it’s a reworking of the Science in the Capitol trilogy, I wanted to find out just how much it adds/leaves out/changes.

Is the difference significant enough to merit a “re-read”? I'm particularly interested in characterization, but I'm also curious if the science itself has been significantly changed, with resulting plot changes.

Thanks!
