Stopping global warming is not worth it, says study

PREVENTING global warming would cost the world economy a devastating $18 trillion (£9.9 trillion, E14.7 trillion) even under the most conservative assumptions, a report out this week will warn.

The cost, equivalent to 45% of world gross domestic product (GDP) for a year, is much greater than any conceivable benefit, according to the report from top economic consultants Lombard Street Research.
