Rising temperatures to make oceans bluer and greener

Scientists say effects of global warming on 'phytoplankton' will intensify the colours

The blues and greens of the ocean will become even bluer and greener by the end of the century as a result of global warming, scientists have found.

Researchers say the colour changes are down to the effect of climate change on populations of tiny water-dwelling organisms, known as phytoplankton, that convert sunlight into chemical energy through photosynthesis, as well as effects on levels of other colourful components of the oceans.
