I made a post asking for topic ideas for the challenge, and the highest scoring suggestion is for paleoclimatology.
Please use the tag paleoclimatology when posting questions for this challenge, and remember to keep the site quality at a good level.
In two weeks, on December 3rd, I will tally up the results to see how we did, in an answer below this post. Feedback? Comment below this post or find me in our chat room. Have fun!
