worse than we thought – plants flowering!

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.

“If a whole plant community starts growing a week earlier than we expect according to these experiments, it’s going to take up a lot more water over the growing season and if you add to that many years of the model projections, you are going to see big changes in the water supply,” said Dr Elizabeth Wolkovich, who is now at the University of British Columbia in Vancouver.
