OCEANS TURNING FROM BLUE TO GREEN, MORE PROOF OF CLIMATE CHANGE ?

Strange changes to the colour of the ocean have spurred investigations from scientists. Satellite data shows that over the last 20 years, colour shifts from blue to green have occurred over 56 per cent of the world’s oceans. The changes are particularly evident in tropical regions near the equator. Researchers say that this subtle greening of our oceans points to the effect that climate change is having on life under the water. Nasa’s Modis-Aqua satellite picked up on a gradual shift from blue to predominantly green hues in over half of the world’s oceans. The area that has changed colour is greater than the entirety of the land on Earth. BB Cael at the National Oceanography Centre in Southampton, UK, and his colleagues analysed the data from NASA and believe the green colouring is a sign of ecosystems changing due to climate change. To delve deeper into the changing colours in the ocean, a NASA mission called Pace is scheduled to launch in January 2024. It will monitor plankton, aerosol, clouds and the ocean ecosystem. In the UK the sea is changing from blue to brown due to sewerage discharges which even worse as it kills marine life immediately, but keeps shareholders happy.
