Damage to oceans will cost $2 trillion

As the seas rise, so will the costs associated with them. The impact of climate change on oceans alone could cost $2 trillion by the end of the century, according to a report by the Stockholm Environment Institute in Sweden.

The report is part of a book, Valuing the Ocean, which is being compiled by the SEI for the UN's Rio+20 Conference on Sustainable Development in Rio de Janeiro, Brazil, in June.
