Study says warm­ing may re­duce sea life by 17%

The News-Times - - NATION / WORLD -

The world's oceans will likely lose about one-sixth of their fish and other marine life by the end of the cen­tury if cli­mate change con­tin­ues on its cur­rent path, a new study says.

Ev­ery 1.8 de­grees Fahren­heit that the world's oceans warm, the to­tal mass of sea an­i­mals is pro­jected to drop by 5 per­cent, ac­cord­ing to a com­pre­hen­sive com­put­er­based study by an in­ter­na­tional team of marine bi­ol­o­gists. And that does not in­clude ef­fects of fish­ing.

If the world's green­house gas emis­sions stay at the present rate, that means a 17 per­cent loss of biomass — the to­tal weight of all the marine animal life - by the year 2100, ac­cord­ing to Tues­day's study in the Pro­ceed­ings of the Na­tional Academy of Sciences. But if the world re­duces car­bon pol­lu­tion, losses can be lim­ited to only about 5 per­c­net, the study said.
