For me no data analysis is necessary to come to a similar conclusion. My parents have a farm in the Netherlands and they are reminded of the lack of rain daily. The most clear example is of the channel ('gracht' in Dutch) around the house. The channel is almost drying up this year. This has never occurred before while my parents or my grandparents occupied the farm.

It was also clear on a recent visit to family in Poland. The corn, potatoes and beets looked yellow and awful for all fields except the parts where somehow there was some water (for example, valleys).
