Southern Ocean Carbon Sink Change
The Southern Oceans are recognised as an important carbon sink currently taking up approximately 15% of anthropogenic CO2. Models predict that as the atmospheric concentration of CO2 increases, so should the ocean’s absorbtive capacity. This seems to be happening in most areas, but not so in the Southern Ocean, which is observed to have a declining ability to absorb CO2.

Number of Disasters per Year
Trends in number of reported disasters. Much of the increase in the number of hazardous events reported is probably due to significant improvements in information access and also to population growth, but the number of floods and cyclones reported is still rising compared to earthquakes. Is global warming affecting the frequency of natural hazards?
