Coral Reefs Coral Reefs
Distribution of the world's coral reefs. Oceans blue carbon sinks, along with coral reefs and kelp communities, all fulfil very important functions in the coastal zone while providing opportunities for jobs and coastal prosperity.

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.

Arctic Ozone Depletion and Stratospheric Temperature Arctic Ozone Depletion and Stratospheric Temperature
Changes in ozone amounts are closely linked to temperature, with colder temperatures resulting in more polar stratospheric clouds and lower ozone levels. Atmospheric motions drive the year-to-year temperature changes.The Arctic stratosphere has cooled slightly since 1979, but scientists are currently unsure of the cause.

Ozone Hole Size Ozone Hole Size
The extent of ozone depletion for any given period depends on complex interaction between chemical and climatic factors such as temperature and wind. The unusually high levels of depletion in 1988, 1993 and 2002 were due to early warming of the polar stratosphere caused by air disturbances originating in mid-latitudes, rather than by major changes in the amount of reactive chlorine and bromine in the Antarctic stratosphere.
