«Ocean warming to cancel increased carbon dioxide - driven productivity.»
Other factors come into play: Increasing carbon dioxide emissions worldwide are making all oceans more acidic, forcing species to use more energy to adapt, leaving them with less energy to reproduce and grow.
This balance is threatened by increasing atmospheric carbon dioxide, which causes ocean acidification (decreasing ocean pH).
When temperatures are low, the ocean dissolves an increasing amount of carbon dioxide, a potent greenhouse gas, further reducing the planet's temperature.
But much of it takes place in oceans, which are susceptible to the increasing amounts of carbon dioxide human activity releases into the atmosphere.
Dr. Houghton and colleagues conclude that the greater certainty in atmospheric carbon measurements has led to an increased certainty in the calculated rate of carbon uptake by land and oceans.
The world's oceans are expected to become more acidic as human activities pump increasing amounts of carbon dioxide into Earth's atmosphere.

Ultimately, the group focused its investigation on the five strategies that appear to hold the most promise: reducing emissions, sequestering carbon through biological means on land and in the ocean, storing carbon dioxide in a liquefied form in underground geological formations and wells, increasing Earth's cloud cover and solar reflection.
As the ocean mass moves north, it absorbs additional carbon dioxide from decomposing organic matter in the water and sediments, increasing acidity.

When carbon dioxide, CO2, from the atmosphere is absorbed by the ocean, it forms carbonic acid (the same thing that makes soda fizz), making the ocean more acidic and decreasing the ocean's pH. This increase in acidity makes it more difficult for many marine organisms to grow their shells and skeletons, and threatens coral reefs the world over.
