Arctic ice is at it's smallest since the mid 1900s, continuing an escalating trend that climate scientists predicted; Romney--not the most timely of joke tellers--mocked commitments to slow climate change during the RNC. (Guardian's article on Arctic ice re-emphasized a connection for me, but I didn't like how they expressed it.) The conservatives' god-of-the-gaps move from "it's not happening" to "it's not caused by man" to "it's not caused primarily by man" to "it's too far along to fix" is no longer humorous. It's been know for a long time, and their mincing uncertainty in order to serve corporations puts the blame wholly on them.
After reading The Windup Girl earlier this year, I became hyper-aware of stories related to crops and genetic engineering.
