worse than we thought – global food production 2

Climate change is set to do far worse damage to global food production than even the gloomiest of previous forecasts, according to studies presented at the Royal Society in London, UK, on Tuesday.

“We need to seriously re-examine our predictions of future global food production,” said Steve Long, a crop scientist at the University of Illinois at Urbana-Champaign, US. Output is “likely to be far lower than previously estimated”.

worse than we thought – oysters affected!

Sydney oyster lovers are in for an unpalatable surprise. A global conference in Monaco next week on the rising acidity of the world’s oceans will hear research that shows a detrimental effect on local oyster species.

A Sydney marine biologist, Laura Parker, will tell the conference that the Sydney rock oyster will be especially vulnerable to the rise in seawater acidity that is expected to take place over the next few decades.

“I thought they would have an impact but not as badly as the results showed,” Ms Parker told the Herald yesterday just before leaving for the world conference, which is supported by UNESCO.

Scientists from the Australian Antarctic Division and the University of Hobart who have led efforts at investigating acidification in the Southern Ocean will also be attending.

Scientists say the problem comes on top of global warming, which is also caused by rising emissions of carbon dioxide and other greenhouse gases.
