Total energy supply in 1995
Total primary energy supply per capita is a common, albeit an imperfect measure of energy efficiency in a country. For instance, neither the impact of climate on energy use (heating, cooling) nor the size of the country ...

The decrease of Arctic sea ice, minimum extent in 1982 and 2007, and climate projections
Sattelite observations of the september extent of sea ice in the Arctic shows in 2007 shows a 23% decrease from the previous minimum, in 2005, and 39% below the average minimum extent for the time period 1979-2000. The b...

Number of trees planted, world map - UNEP Billion Tree Campaign, May 2008
The UNEP Billion Tree Campaign represents a unique worldwide tree planting initiative, aimed at empowering citizens to corporations and people up to presidents to embrace the climate change challenge. By 2008, 18 months ...

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...

Cumulative impacts on the marine environment
Climate change may, through effects on ocean currents, elevated sea temperatures, coral bleaching, shifts in marine life, ocean acidification and much more severely exacerbate the combined actions of accelerating coastal...

Plankton distribution changes, due to climate changes - North Sea
With melting sea ice and warming of the oceans, marine species change their distributions, affecting entire food chains and ocean productivity. In 2005 the subtropical dinoflagellate Ceratium hexacanthum was found in CPR...

Coastal regions with observations of dense shelf water flushing
Knowledge and mapping of these processes is still scarce due to uneven research effort. The map shows sites with known dense shelf water cascading phenomena, which often may involve the 'flushing' effect. It is most like...

Distribution of coldwater and tropical coral reefs
Coral reefs are marine ridges or mounds, which have formed over millennia as a result of the deposition of calcium carbonate by living organisms, predominantly corals, but also a rich diversity of other organisms such as...

Trends in natural disasters
With growing population and infrastructures the world’s exposure to natural hazards is inevitably increasing. This is particularly true as the strongest population growth is located in coastal areas (with greater exposur...

Climate change and tropical coral reefs, scenarios for bleaching events
Projected areas of above normal sea temperature where coral bleaching is likely to occur for the SRES A2 scenario (continuing current trends) by two different models, the PCM (1.7°C increase in 100 years) and the HadCM3 ...

Acidification due to climate change - impacts for oceans and coral reefs
As carbon concentrations in the atmosphere increase from land use changes and emissions from fossil fuels - so do concentrations in the ocean, with resultant acidification as a natural chemical process. The skeletons of ...

Atmospheric concentrations of carbon dioxide (CO2) - Mauna Loa or Keeling curve
Atmospheric concentration of CO2 is steadily rising, and oceans directly assimilate CO2. As ocean concentration of CO2 increases, the oceans automatically become more acidic. This, in turn, may have severe impacts on co...

Tropical sea temperature rises and coral reefs - climate change scenarios
The impacts of coral reefs from rising sea temperatures. When coral reefs become heat-exposed they die, leaving the white dead coral, also known as bleaching. With even moderate pollution, the coral are easily overgrown ...

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...
