A plant biologist observes that a plants flowering time has shifted forward by 9 days over the past 30 years due to climate change. If this trends continues, how many days earlier will flowering occur in 60 years from now?

**How Climate Change Is Shifting Plant Flowering Times Across the U.S.** For decades, scientists have watched closely as growing seasons and plant cycles respond to a slowly warming climate. A growing body of research shows that flowering times in plant species across the United States are moving earlier—on average, 9 days earlier over the past 30 years. This subtle yet measurable shift reflects nature’s sensitivity to rising temperatures and is raising important questions about the future of ecosystems, agriculture, and biodiversity. Why is this trend gaining attention now, especially in 2024? Rising public awareness of climate impacts, combined with observable changes in local landscapes—earlier blooms in gardens, shifting migration patterns of pollinators—has made plant phenology a relatable frontline indicator of global change. Social media, citizen science projects, and community gardening networks amplify these observations, inviting broader conversation about how living systems adapt. ### How the Observed Shift Reflects Long-Term Climate Trends
