Oceans Storing Excess Heat From Warming April 8, 2011

A fleet of more than 3,200 robot weather sensors drifting on the world’s oceans has found that more than half of Earth’s excess heat being absorbed by oceans is stored in the Southern Hemisphere.

The weather robots launched by the Argo Project also have found that ocean temperatures are rising as the planet warms under climate change.

It also confirmed that 90 percent of the excess heat being absorbed by the planet is being stored in the oceans.

But since the array of Argo sensors has been around only for seven years, it has yet to document any long-term trends in rainfall and temperature.
