Study Says Plants Flowering Faster

Warming temps cause earlier springs


A study published on Wednesday in the journal Nature suggests that warming temperatures are causing plants to flower much faster than expected by scientific models. The study, led by Dr. Elizabeth Wolkovich, observed the timing of flowering and leafing in 1,634 plant species across the world. It found that timing estimates underestimated the speed of flowering by as much as eight times and leafing by four times. Earlier plant growth could require more irrigation worldwide, increasing demand for water. “In terms of long-term observations, the records are very coherent and very consistent and they suggest for every degree celsius of warming we get we are going to get a five- to six-day change in how plants leaf and flower,” she said.
