The shell of a tiny snail that is an important food source for fish and birds in the water surrounding Antarctica is being dissolved in an ocean that is becoming more acidic due to climate change, new research shows.
Increasing carbonic acid levels in the world’s oceans are due to the water absorbing carbon dioxide from the air.
The source of that greenhouse gas is the burning of fossil fuels.
The water’s pH is now dropping faster than at any other time in the past 300 million years.
When this is combined with natural upwelling of more acidic waters from the deep, at least one creature has been found to be unable to cope with the more caustic waters.
