June 15, 2018 –Warming seas are driving commercial seafood poleward into waters controlled by other countries, setting up international conflicts.
Atlantic mackerel, a fatty schooling fish, for years has been caught by fleets in parts of Europe and sold around the world—where it gets pickled, grilled, smoked, and fried. It is among the United Kingdom’s key exports.
But a decade ago, warming temperatures began driving this popular fish north, into seas controlled by Iceland. Almost overnight, this seafood gold began shredding relations between some of the world’s most stable governments. It led to unsustainable fishing, trade embargoes, and boat blockades. It even helped convince Iceland to drop its bid to join the EU. And that was among friendly nations.
Welcome to the climate-change food threat you may not have considered.
In many parts of the world overfishing is already draining the ocean of important sea life. But a paper published today in the journal Science suggests potentially explosive ocean fish wars are likely to simmer across the world as warming temperatures drive commercial fish species poleward into territories controlled by other nations, setting up conflicts with sometimes hostile neighbors that are suddenly forced to share. That could lead to far fewer fish, economic declines and, in some areas, serious threats to food security.
