For the first time in 35 years, fisheries officials have recommended shutting down the 2014 Northern shrimp season in the Gulf of Maine, where water temperatures have been running about 5 degrees warmer than the previous hundred year average. They cite a "collapsed" stock, adding, "Three successive years of recruitment failure and continuing warm temperatures indicate poor prospects for the near future." Lobster may be next, possibly followed by moving to Planet B. No, wait....

“Decisions like this one show how fishermen are on the front lines of the battle against climate change.This is not a nebulous, maybe-someday-in-the-future problem." — Michael Conathan at the Center for American Progress.

The cooler a liquid, the more gas it can dissolve.

If ocean-water gets too warm, the oxygen dissolved in it slowly evaporates and returns to the air. Without enough oxygen to breathe, sea-animals' growth is slowed and the plankton procreates at slower rate.

- less food at the bottom of the food-chain
- sea-animals with gills don't get enough oxygen
