★Since the mid-19th century, the land-ocean system has been profoundly disrupted with the use of fossil fuels and the development of man-made activities. The ocean helps stabilize the climate by absorbing heat and greenhouse gases.
★Massive carbon dioxide emissions, triggering the greenhouse effect is a challenge of the century.
★Scientists are now considering manipulating the ocean to help it absorb more greenhouse gases.

Since the mid-19th century, the land-ocean system has been progressively and profoundly disrupted: the use of fossil fuels and the development of man-made activities have led to massive carbon dioxide, methane and other gas emissions, increasing the natural greenhouse effect and triggering global climate change. This book outlines how the ocean helps stabilize the climate by absorbing the vast majority of the heat generated by the greenhouse effect, as well as much of the carbon dioxide discharged by human activities. To achieve carbon neutrality, we need to change direction and put an end to the use of fossil fuels. The great potential of marine renewable energies can help achieve just this. Geoengineers are even considering manipulating the ocean to help it absorb more greenhouse gases...
