Experiments Underestimate Plant Responses to Climate Change
ScienceDaily (May 2, 2012) — Experiments may dramatically underestimate how plants will respond to climate change in the future. That's the conclusion of an analysis of 50 plant studies on four continents, published this week in an advance online issue of the journal Nature, which found that shifts in the timing of flowering and leafing in plants due to global warming appear to be much greater than estimated by warming experiments.
Predicting plant responses to climate change has important consequences for human water supply, pollination of crops and the overall health of ecosystems. Shifts in the timing of annual plant events -- which biologists call "phenology" -- are some of the most consistent and visible responses to climate change.
Long-term historical records show that many plant species have shifted their leafing and flowering earlier, in step with warming temperatures over recent decades. Because historical records are not available in most locations and climate change may produce temperatures higher than previously recorded, however, ecologists often rely on experiments that warm small field plots to estimate plant responses to temperature and project future conditions.
