By absorbing CO2 the ocean is becoming more acidic, and this happens at a rate faster than during any other period in the past 300 million years.

As water temperature increases some direct impacts on salmon biology can be predicted. These can include physiological stress, increased depletion of energy resources and also increased susceptibility to disease.

The projected water temperature increase will greatly affect the most biodiversity rich ecosystems of the oceans – the tropical coral reefs – which harbor some 25 per cent of all marine species.
