Climate change-driven shifts in the circulation of waters to the deepest reaches of the ocean around Antarctica, which could reverberate across the planet and intensify global warming, are happening decades “ahead of schedule”, according to new research.

Scientists have said that an acceleration of melting Antarctic ice and rising temperatures, driven by the emission of planet-warming gases, is expected to have a significant effect on the global network of ocean currents that carry nutrients, oxygen and carbon.

This could not only threaten marine life, but it also risks changing the ocean’s crucial role in absorbing carbon dioxide and heat.

An earlier study using computer models suggested “overturning circulation” of waters in the deepest reaches of the oceans would slow by 40 percent by 2050 if emissions remain high.

But new research released…
