Plants flower faster than climate change models predict

Scientific models are failing to accurately predict the impact of global warming on plants, says a new report.

Researchers found in long-term studies that some are flowering up to eight times faster than models anticipate.

The authors say that poor study design and a lack of investment in experiments partly account for the difference.

They suggest that spring flowering and leafing will continue to advance at the rate of 5 to 6 days per year for every degree celsius of warming.

The results were published in the journal Nature.

For more than 20 years, scientists have been carrying out experiments to mimic the impacts of rising temperatures on the first leafing and flowering of plant species around the world.

Researchers had assumed that plants would respond in essentially the same way to experimental warming with lamps and open top chambers as they would to changes in temperatures in the real world.
