Over the past 20 years, huge swathes of the world’s oceans have changed colour, displaying a subtle greening towards the tropics that researchers say points to the effect of climate change on life in the world’s seas.
In the new research published recently, scientists said they had detected shifts in colours across more than half of the world’s oceans – an expanse bigger than Earth’s total land area.
