We see shifts in cyclical phenomena around Chandos.

Phenology is the study of periodic plant and animal life cycle events, and how these are influenced by climate, elevation, etc.  Recently the field seems to have broadened to include other periodic events related to ecology and climate, such as ice cover.  Certain events are very sensitive to climate change and can be useful indicators of such changes,  and in historical instances become proxies for what the climate was actually like.  Quoting Wikipedia, “viticultural records of grape harvests in Europe have been used to reconstruct a record of summer growing season temperatures going back more than 500 years.  In addition to providing a longer historical baseline than instrumental measurements, phenological observations provide high temporal resolution of ongoing changes related to global warming.
