Understanding Phenology and Its Importance
Phenology is the study of the timing of biological events, such as plant blooming and bird migrations. This scientific field assesses how climate changes impact natural cycles by comparing historical data with current observations. Researchers, including Richard Primack from Boston University, utilize historical records to understand shifts in the timing of these natural events, revealing that flowers and trees are blooming earlier than in the past. This early blooming is attributed to a warming climate, with flowers now appearing weeks ahead of their traditional schedules.
