David's Deep Dives: Phenology, Changing Natural Cycles, & Weather
Manage episode 474372711 series 3613017
The timing of natural events like bird migration, animal hibernation, and pollen release are being significantly disrupted by climate change, with profound impacts on ecosystems and human health. Phenology is incredibly sensitive to temperature changes, making it one of the most visible indicators of our changing climate.
• Phenology is the study of cyclical natural events in plants and animals
• Warming temperatures cause many plants to flower earlier and animals to emerge sooner
• Growing seasons are lengthening as winter contracts from both ends
• Ecological mismatches occur when interacting species respond differently to climate changes
• Pollen seasons are starting earlier, lasting longer, and producing 20% more pollen than 30 years ago
• Agricultural crops face increased risk from early spring warmth followed by freezes
• Some fruit trees require specific winter chill periods that are becoming less reliable
• Invasive species often gain advantage by leafing out earlier than native plants
• Amphibians and fish show some of the most dramatic shifts in timing (up to 60-80 days)
• Citizen scientists can contribute valuable data through the Nature's Notebook program
