The latest UN Climate Change assessment shows the depth that the ocean is suffering with the effects of increased levels of carbon dioxide from climate change.

Leading marine science body, the International Programme on the State of the Ocean (IPSO), says that the most alarming threat comes from mass carbon impacts to the ocean which could trigger mass extinction events.

Alex Rogers, IPSO scientific director and professor of conservation biology, Department of Zoology, University of Oxford, said: “The IPCC’s findings reflect exactly what we are seeing in the ocean – massive changes in the distribution of marine organisms and marine ecosystems globally.”

Professor Rogers warned that the lethal trip of acidification, warming and de-oxygenation in the oceans is unprecedented in the carbon record. This of course could spell bad news for both wild and farmed fish species.

He added that there can be no stronger imperative for global governments to take action to reduce greenhouse gas emissions in the shortest time possible.

IPSO is again calling for more research on the heating effects of climate change – its latest report is due out next week.
