Autumn's early arrival

There's no denying it, Autumn arrives earlier every year. Whether as a consequence of Climate Change or some natural anomaly, the last decade has seen a change in the nature of the seasons. To my senses, Summer and Winter have contracted, becoming much shorter defined events, whilst Spring and Autumn expanded, appearing much more nebulous in nature. My calender tells me it's easily still summer, though my senses and many natural indicators suggest otherwise. Weird times.
