Looks cold. Valentina Zharkova suggests that the cold summer in Great Britain may be a harbinger of her forecasted return of the (1645-1715) Maunder Minimum (low solar activity), a Granger cause of the Little Ice Age.

I don't know if climate change is real or not. But if 90%+ scientists believe it is real then I feel like it is my job to do the appropriate sort of environmental economics (i.e., discuss incentive-based policy and suggest it should be implemented).
Plus, it was warmer later in the week. Here I am hiking up Salisbury Crags:
