spring flowering

In recent decades, trees and plants have begun to flower earlier in the spring. Many studies have shown that this advancement in timing is due to climate change, particularly increases in air temperature. However, these studies have generally been conducted in small areas. A recent study conducted across Europe reports that the timing of spring flowering and other events in 16 tree species has been advancing. More importantly, the timing of flowering trees in warmer and cooler regions of Europe is becoming more similar, which has wide spread ecological consequences.
