Global Warming May Shrink Size Of Fish 24% By 2050

Should we expect fishermen to try to find ways to stop greenhouse gas emissions from their boats? Doubtful, but if the warming trend continues, the average size of their catch is going down, down, down. Via Live Science:

Warming temperatures could lead to smaller fish in the world’s oceans, according to new research.

Based on a study of more than 600 species from around the globe, researchers from the University of British Columbia found that many fish won’t be able to keep up their body weight as the water warms. The scientists projected that the average maximum body size for the world’s fish could decline by up to 24 percent by 2050.

“We were surprised to see such a large decrease in fish size,” the study’s lead author, William Cheung, said in a statement. “Marine fish are generally known to respond to climate change through changing distribution and seasonality. But the unexpectedly big effect that climate change could have on body size suggests that we may be missing a big piece of the puzzle of understanding climate change effects in the ocean.”…

    Agriculture takes a hit, too. The northern latitudes which become optimal for food crops tend to have poor-quality soil for grain crops, and there are other problems.

    Global warming causes more tsunamis and super cyclones and bear attacks and genital warts too.

      We had a hurricane carry an entire melting iceberg full of bears with genital warts to the Mississippi Gulf Coast. There was trouble until they discovered the casinos. Now they’re mixing in with the rest of the ill-mannered, hairy, warty players in the nickel slots area.

    Seems counter intuitive, I’ve always had problems with shrinkage in cold water not warmer. What will science discover next!

    Warmer climates might shrink fish, but according to Ophiologists, dramatically increased temperatures in rain forests for example, could assist in the exponential growth of reptiles like giant monster snakes, and perhaps the return of Titanoboa: http://youtu.be/NCTKHHfsM7Y
