Empire of Ice book coverWelcome back, dear readers, to another Grist book giveaway. There are prizes at stake here, so listen up. We’re giving away 10 autographed copies of Gretel Ehrlich’s new book In the Empire of Ice. To nab one, all you have to do is answer this question — in 400 words or less: “How is climate change messing with the people who call the (formerly frozen) Arctic home?”

To submit your answer, use the comment area below. Remember: keep it under 400 words. We’ll pick our 10 lucky winners — randomly, of course — on May 5. Happy reading!
