Now that I read it, it is really interesting.
The first one is more of a “joke” than a “hoax” — and credit the perpetrators for trying to right things (if I understand what happened correctly).
1) Relate the hoax in the article to the Hadley CRU. Concentrate on the inducements to the hoaxters as related to professional standing and to grant money. Extra credit for pulling in Marxist / Globalist machinations, or the Gaia hypothesis.
2) Discuss the odds that Beringer White Zinfandel begins as water.
Cheers!
