Climate change may have contributed to the fall of North America's first and largest pre-European city — and the proof may be in the poop, researchers said this week. A new study published in the journal Proceedings of the Natural Academy of Sciences details how fecal records linked to Cahokia, one of the most prominent agricultural sites in North America, gives clues into how declining precipitation and serious flood events may have impacted the population of the city, which is located outside of modern-day St. Louis.


"Cultures can be very resilient in face of climate change but resilience doesn't necessarily mean there is no change," coauthor Sissel Schroeder said in a statement. "There can be cultural reorganization or decisions to relocate or migrate. We may see similar pressures today but fewer options to move."

First off: Bangkok Wakes to Rain, the intricately wrought, elegantly crafted debut novel by the Thai-American author Pitchaya Sudbanthad, isn't really about climate change. This tale set in the sprawling subtropical Thai capital is ultimately a kind of family saga — although its interconnected characters aren't necessarily linked by a bloodline. What binds them is their relationship to a small parcel of urban land on which has variously stood a Christian mission, an upper-class family house, and a towering condominium. All of the characters have either called this place home or had some other significant connection to it.
