As world leaders prepare for international climate change negotiations next week in Durban, South Africa, a new study out this week depicts the widespread threats that climate change presents for marine fisheries.
The bottom line? Emissions from the burning of fossil fuels are presenting very long-term if not irreversible threats for the oceans.
Economists and top fisheries scientists at the University of British Columbia published a paper on Sunday in the journal Nature Climate Change that outlines the many challenges fisheries face from climate change, and how this can impact the global economy and hundreds of millions of lives.
Global marine fisheries are underperforming, mainly from rampant overfishing, but climate change also creates several serious threats to the future productivity of fisheries. These chemical and physical changes linked to climate change such as decreased oxygen levels, changes in plankton communities and plant growth, altered ocean circulation and increased acidity can disrupt the basic functioning of marine ecosystems and thwart any potential recovery of global fish stocks.
The study outlines how impacts can scale up from changing ocean conditions to the global economy, but the authors note that the true scope of impacts to employment are hard to predict.
