Yet here in Belgium I'm walking around in a puffy winter coat hat and gloves, whereas preceding winters would wear less. The point is, isolated observations don't tell us much about climate. In winter, warm and cold anomalies travel in waves (Rossby waves) around the pole, and mostly offset each other in the hemisphere average. Problem is that human population distribution evolved, over centuries, such that most people live in places with comfortable climates - and when we change the typical wave patterns, such distribution may no longer be a good adaptation to the new climate.
