more acidic conditions, microbes will produce more volatile organic compounds such as di-methyl sulphide,
some of which escapes to the atmosphere and causes clouds to develop. More clouds would mean cooler
conditions, which could potentially slow global warming.
Calculating the effect of ocean acidification on people and economies is virtually impossible, but
it could be enormous. Take the impact on tropical corals, assuming that warming and other pressures such as
pollution do not decimate them first. Reefs protect the shorelines of many countries. Acidification could
start eating away at reefs just when they are needed more than ever because of rising sea levels.
'No serious scientist believes the oceans will be devoid of life,’ says Caldeira. 'Wherever there is
light and nutrients, something will live. A likely outcome will be a radical simplification of the ecosystem.
'Taking this and other scientists' views into account, it seems clear that acidification will mean the loss of
many species so our children will not see the amazingly beautiful things that we can. It is important to tell
them to go and see the corals now before it is too late.
