I've read a few articles about James Hansen since he announced his resignation from NASA. The ones that have had the most impact have been those touching on the personal.
Eli Rabett has written an article, saying quietly: Eli Appreciates Hansen.
A man of worth, who is shifting societies towards a clean futureEli's post is well worth a read. It includes a brief bio plus a couple of lovely anecdotes that help put the blogosphere and we piddly bloggers in perspective. (The blogosphere does not shape the world, it's people like James Hansen who shift societies.)

He describes how Dr Hansen emerged into the public spotlight when "on a blistering June day in 1988 he was called before a Congressional committee and testified that human-induced global warming had begun."
The Gillis article also gives a thumbnail sketch of Hansen's life and career.

For some of Hansen's writings, go to his personal website at Columbia University. There is a heap of material to read there. And if you haven't already done so, get a copy of his most well-known book:
