We arrived at the Bavarian village of Iffeldorf the morning after the first snow, in late November, 2015. Dr. Uta Raeder, Co-Director of the Technical University of Munich (TUM) facility, greeted us in the parking lot. We huddled close, straining to catch her words before the wind, or traffic noises took, them away. She and her colleagues has been considering keeping us indoors. Instead they led us toward the boathouse, to see how they are monitoring how the climate is changing Germany’s lakes.
