Damage to world's oceans 'to reach $2 trillion a year' http://apocadocs.com/s.pl?1332337028
The cost of damage to the world's oceans from climate change could reach $2 trillion a year by 2100 if measures to cut greenhouse gas emissions are not stepped up, a study by marine experts said on Wednesday.
The study found that without action to limit rising greenhouse gas emissions, the global average temperature could rise by 4 degrees Celsius by the end of the century causing ocean acidification, sea level rise, marine pollution, species migration and more intense tropical cyclones. It would also threaten coral reefs, disrupt fisheries and deplete fish stocks....
If cuts in emissions of planet-warming greenhouse gases were carried out more urgently and temperature increases were limited to 2.2 degrees C, nearly $1.4 trillion of the total cost could be avoided, the study found.
However, such progress would require the widespread use of radical carbon removal technologies like sucking carbon dioxide out of the atmosphere, Frank Ackerman, one of the report's authors told Reuters.
"The faster we stop emissions rising, the lower the damage will be. But on current technology, I wouldn't be surprised if we end up on a 4 degree C pathway," said Ackerman, senior economist and director of the Climate Economics Group at SEI's U.S. Center.
