Climate change making Aussie tuna chubbier
Just when you thought global warming was all gloom and doom, news from Down Under that climate change is making the local tuna catch fatter.
Apparently as waters in parts of the southern hemisphere heat up, strong southeasterly winds drive nutrients to the surface, meaning good times for the creatures which eat them. Since tuna are perched atop the maritime food chain - or close to it, after sharks and us - they in turn benefit. As a result, the fish being caught this year are apparently bigger and of better quality than in the past.
That's a good thing for sushi fans, of course. However, it may not mean much in the big picture - the popular fish is disappearing in the Mediterranean and much of the Pacific due to overfishing.
