‘Acidifying oceans’ threaten food supply, UK warns

Acidification of the oceans is a major threat to marine life and humanity’s food supply, Hilary Benn is to warn as the UN climate summit resumes.

The UK environment secretary will say that acidification provides a “powerful incentive” to cut carbon emissions.

Ocean chemistry is changing because water absorbs extra CO2 from the air.

Some believe this impact of rising CO2 levels could be as big as climatic change, though it is rarely discussed within the UN climate convention.

The UN summit in Copenhagen, which started a week ago, is scheduled to conclude on Friday, when more than 100 world leaders will attend in an effort to agree a new global treaty on climate change.
