Warming weather can trick flowers into blooming without pollinators

A cherry blossom tree in Japan is more than a cultural icon; it is a biological stopwatch. Over the last 50 years, these trees have begun blooming progressively earlier as temperatures rise, sometimes shifting their peak by as much as 14 days. This creates a dangerous phenomenon called a phenological mismatch. While the flowers respond to the warmth of the air, the bees and butterflies they depend on for pollination often rely on different cues, such as the length of the day, to emerge from hibernation.
