Excellent course! My primary goal was to learn more about climate change and to understand its issues and impacts. Jon Nese (primarily) and Bill Syrett (secondarily) presented all this information in a professional yet impassioned manner. Their materials were easy-to-understand, and both readily answered the many questions asked by the participants. The multiple 15-minute presentations by guest speakers were disappointing, though, because the speakers tended to cram as much information as possible into the limited time frame. It appeared that Penn State wanted to give speaking opportunities to as many as of their professors as possible, but I would have preferred 30-minute sessions from half the number. The accommodations and meals for the trip worked out very well. The food at the Nittany Lion Inn was excellent, especially the lunch and dinner buffets. My only disappointment with accommodations was the trolley that transported us back and forth from the hotel to the Penn State locations as well as to off-site locations: the wooden slat seats were very uncomfortable, even for the short rides, and the driver always had the air conditioner on, which blew in strong gusts, even though the outside temperatures were quite unseasonally cool. Based on my participation in this trip, I plan to sign up for the sister week on astronomy for 2020.
