Benefits of marine and coastal ecosystems to human wellbeing
Besides the well-known economic value of fisheries, there are several other activities generating significant revenues in coastal and marine areas. Tourism has become one of the world’s fastest growing industries, providing a significant proportion of the GDPs of many developing countries. Small island states are particularly reliant on coastal and marine tourism. In the Caribbean, for example, the industry accounts for a quarter of the total eco...

Oceans Carbon Fluxes
An important role played by the ocean is the storage and exchange of CO2 with the atmosphere, and its diffusion toward deeper layers. At high latitudes, dense waters sink, transferring carbon to the deep ocean. Warming of the ocean surface inhibits this sinking process and therefore reduces the efficiency of CO2 transport and storage. Furthermore, as water warms up, the solubility of CO2 declines, therefore less gas can be stored in the sea water...

World Greenhouse Gas Emissions by Sector
All transport accounts for approximately 13.5% of the total emissions, while deforestation accounts for approximately 18%. However, estimates of the loss of marine carbon-binding ecosystems have previously not been included.

Regional CO2 emissions
World carbon dioxide emissions by region, 1950-2006.
Under the terms of the 1992 United Nations Framework
Convention on Climate Change (UNFCCC), countries that have contributed the most greenhouse gas emissions have a responsibility to dramatically cut emissions and to assist the most vulnerable peoples and regions to adapt.
