The scales of conifer cones react to adjustments in humidity. In dry climate, the scales open outward to launch seeds for dispersal by wind. Conversely, elevated humidity causes the scales to shut inward, defending the seeds and stopping dispersal in much less favorable circumstances. Observing these adjustments can present a fundamental, localized indication of impending climate shifts.
This pure hygrometer has been utilized for generations, notably in conventional practices and folklore. Whereas not as exact as fashionable meteorological devices, observing conifer cone habits gives accessible, readily observable insights into short-term atmospheric adjustments, probably useful for out of doors actions or in areas with restricted entry to know-how. It gives a tangible connection to pure processes and the wealthy historical past of climate prediction.
