Impact of Climate Change on Spring

The video discusses a visualization tool from the National Phenology Network that tracks the timing of spring leaf emergence across the US. It highlights how spring arrived earlier in the eastern US, with New York City experiencing it 33 days earlier than usual, while parts of the West Coast saw a delay. This pattern is linked to climate change, with warmer winters in the east and cooler, wetter winters in the west. The video also addresses the ecological impacts of these changes, such as disrupted migration patterns and longer allergy seasons.
