Heatwave study raises new climate fear
Global warming could reduce harvests and plant growth, with a serious effect on farm productivity, scientists will warn today.
The finding, based upon an examination of the effects of the 2003 heatwave in Europe, is of particular concern because many scientists previously assumed that global warming would increase plant growth, with beneficial effects for harvests and the environment.
In a study to be published today in the peer-review journal Nature, scientists from several European research institutes and universities found that the growth of plants during the heatwave was reduced by nearly a third.
In Italy, the growth of maize dropped by about 36 per cent. Oak and pine trees also grew much less, the study found, reflecting an overall reduction of 30 per cent in plant growth.
