SLCPs and Sea-Level Rise
SLCP control measures could help reduce the rate of sea-level rise, one of the most concerning effects of climate change. An immediate implementation of control measures could reduce the rate of sea-level rise by about 2...

Sea level variations in the Mediterranean
Sea level is rising significantly in the Eastern Mediterranean, with an average 12 cm rise registered on the Levantine coast since 1992. However, causes are not yet known, and a cause-effect relationship with climate cha...

Changing Caspian
At present, most scientists seem to agree that climate change plays a significant role in sea level fluctuations in the Caspian Sea, since temperature increases and changes in precipitation directly impact the overall w...

Estimates of people flooded in coastal areas in the 2080s as a result of sea-level rise and for given socio-economic scenarios and protection responses
The lines represent IPCC Special Report on Emissions Scenarios (SRES) based on different world views. The differences in impacts between the SRES scenarios for the same amount of sea-level rise and protection response re...

Hydropower potential (theoretical possitibility for electricity generation)
xHydropower, generating electricity through turbines, represents a clean and renewable energy source, but not without problems. Dams and reservoirs disrupt the natural flow, and may increase siltation and evaporation, in...

Sensitivity, adaptability and vulnerability
Sensitivity is the degree to which a system is affected, either adversely or beneficially, by climate-related stimuli. Climate-related stimuli encompass all the elements of climate change, including mean climate characte...

Impact of Sea Level Rise in Banjul, Gambia
Climate change is expected to cause a rise in sea level. Sea level rise will have a significant impact on coastal areas, especially coastal megacities such as Banjul, the Gambia. This graphic shows the expected sea level...

Climate change vulnerability in Africa
Multiple stresses make most of Africa highly vulnerable to environmental changes, and climate change is likely to increase this vulnerability. This graphic shows which of the regions of Africa (North Africa, West Africa,...

Sea level rise: Costa Rica coastal communities under threat
Sea level rise is an important indicator of climate change. A rise in sea level may result in flooding, salinisation of fresh water, coastal erosion and in some cases loss of land to the ocean. As depicted, some coastal...

Intense hurricanes in the Atlantic Basin
Global average temperature increased by 0.6 ° C over the last century, while sea levels rose by 9 to 20 cm. The IPCC projects increases in the global average surface temperature by between 1.4°C and 5.8°C and in sea leve...

Sea level rise due to the melting of mountain and subpolar glaciers
Oceans change as a result of the impact of climatic variability on glaciers and ice caps that further contributes to fluctuation sin sea leve. Observational and modelling studies of glaciers and ice caps indicate an ave...

Estimated contributions to sea-level rise (1993-2003)
The two main reasons for sea-level rise are thermal expansion of ocean waters as they warm, and increase in the ocean mass, principally from land-based sources of ice (glaciers and ice caps, and the ice sheets of Greenla...

Sea level change: estimations and predictions
This resource includes four graphics that explain sea level change, an expected consequence of climate change. The first graphic, 'Relative Sea Level Over the Past 300 Years', shows the changes in sea level rise, in metr...

Causes of sea level rise from climate change
A significant sea level rise is one of the major anticipated consequences of climate change. This graphic explains the causes of sea level change according to the Intergovernmental Panel on Climate Change (IPCC). It expl...

The Caspian Sea coastlines vulnerable to flooding
Most of the water flowing into the sea comes from coastal rivers. The quantity and quality of this water, particularly that of the Volga, are key variables in the balance of the Caspian Sea. To this must be added rainfal...
