Global warming affects spring wildflower blooms
Data gathered by citizen scientists suggests that bluebells and some other spring wildflowers are slipping out of synch with seasonal temperature cycles. A study published this week in Global Change Biology looked at 22 species of plants; all of them were found to be responding to warming temperatures in spring, by changing when their leaves or flowers emerged.
