Earth's blue oceans are turning green because of climate change. Scientists found significant colour changes to seas around the world over the past two decades that cannot be explained by natural variations.
The colour shifts have occurred over 56 per cent of the world’s oceans. Tropical ocean regions near the equator have become particularly green, researchers found.
Scientists cannot say how exactly marine ecosystems are changing but the team, including scientists from the UK’s National Oceanography Centre, are certain of one thing: human-induced climate change is probably causing the colour shift.
