Blue Carbon - The Role of Healthy Oceans in Binding CarbonBlue Carbon - The Role of Healthy Oceans in Binding Carbon
Very large cuts in emissions of greenhouse gases are needed if we are to avoid the worst effects of global climate change. This report describes the vital contribution that ecosystems can and must make to these efforts.

Species Turnover Species Turnover
Change in the initial species richness in 2005 relative to 2001-2005 average (high-range climate change scenario). Studies predict species invasion will be profound in the Arctic and Southern Oceans. Among others these changes could result in a significant turnover of species of more than 60% of present biodiversity. This has the potential to disrupt a range of marine ecosystem services including food provisioning.

Carbon Cycle Carbon Cycle
Blue and green carbon process.Oceans are crucial in the global carbon cycle. It was here where life first evolved; they are the source of our wealth and development. The living oceans capture over half of all the Green carbon – the carbon bound by living organisms through photosynthesis.

Sea Level Anomalies Sea Level Anomalies
Melting and warming will have consequences on ocean circulation. Additionally melting of inland glaciers and continental ice sheets on Greenland and Antarctica, and the thermal expansion of ocean waters are causing sea level rise.
