Carbon dioxide concentrations predicted to occur in the ocean by the end of this century will interfere with fishes' ability to hear, smell, turn and evade predators, says Professor Philip Munday of the ARC Centre of Excellence for Coral Reef Studies and James Cook University.

Phil, you're a moron. The seas have less CO2 in them now than they did 200 years ago because of outgassing of CO2 due to the warming up after the Little Ice Age. The seas have less CO2 now than they did during many, many very long periods in the earth's past and the fish did just fine then. And, Phil, if the fish are trying to "evade predators," which predators are they trying to evade? Squid, whales, porpoises, or other fish? Given that nearly all predators of fish are other fish, how are those other fish going to be able to exercise their predation if CO2 is affecting their ability to hear their prey, smell their prey, and turn to eat their prey?

Phil forgot to mention that the oceans hold more CO2 when they are cold and less CO2 as they warm. If CO2 really caused global warming, this would mean that climate was in a positive-feedback loop and CO2 and the oceans would drive the climate into either a permanent ice-age or a permanent tropical environment.

Since climate appears to have fluctuated between these extremes over time, it means that CO2 is not the cause of global warming.
