El Niño-Southern Oscillation (ENSO) Phenomenon El Niño-Southern Oscillation (ENSO) Phenomenon
El Niño describes 'the warm phase of a naturally occurring sea surface temperature oscillation in the tropical Pacific Ocean', and southern oscillation refers to 'a seesaw shift in surface air pressure at Darwin, Australia and the South Pacific Island of Tahiti'. This graphic explains the El Niño-Southern Oscillation Phenomenon, showing the differences between a normal year and an El Niño year.

ENSO impact on Southern Africa ENSO impact on Southern Africa
El Niño describes 'the warm phase of a naturally occurring sea surface temperature oscillation in the tropical Pacific Ocean', southern oscillation refers to 'a seesaw shift in surface air pressure at Darwin, Australia and the South Pacific Island of Tahiti' amd La Nina refers to the cooling phase of the same temperature oscillation that causes El Nino. This graphic shows how the El Nino phenomenon changed weather conditions in southern Africa in...

Impact of Temperature Rise on Robusta Coffee in Uganda Impact of Temperature Rise on Robusta Coffee in Uganda
Developing countries, whose economies often rely heavily on one or two agricultural products, are especially vulnerable to climate change. This graphic shows that with an increase of only 2 degrees Celsius, there would be a dramatic decrease in the amount of land suitable for growing Robusta coffee in Uganda.

African wildlife under threat from climate change African wildlife under threat from climate change
Climate change poses a threat to wildlife because as climatic conditions change, many species may be unable to tolerate the changes. This graphic shows the numbers of mammals, birds, reptiles, amphibians and fish species that are critically endangered, endangered and vulnerable in various regions of Africa and in Africa as a whole, as of 1998.

Comparison between modeled temperature rise and observations of temperature since 1860 Comparison between modeled temperature rise and observations of temperature since 1860
Natural forcing (solar variation and volcanic activity) alone cannot explain the recent global temperature increase. This graphic shows the temperature anomalies (in degrees Celsius) that were expected to occur due to natural forcing only, from the year 1850 to the year 2000, according to climate models, and the actual anomalies that have occurred. The graphic also shows the expected and actual anomalies due to anthropogenic (human-caused) factor...

History of variations of the temperature for Africa in relation to the World History of variations of the temperature for Africa in relation to the World
Africa is following the global trend of recent increases in temperatures. This resource includes three graphics. The first shows the main temperature anomaly in degrees Celsius in Africa from 1900 to 2000. The second shows departures from the 1961 to 1990 average temperatures, in degrees Celsius, on a global scale for the time period 1860 to 2000. The final graphic shows departures from the 1961 to 1990 temperatures, in degrees Celsius, for the N...

Nile Delta: Potential Impact of Sea Level Rise Nile Delta: Potential Impact of Sea Level Rise
The potential impacts of sea level rise on the Nile Delta are expected to include a decline in water quality that would affect freshwater fish, the flooding of agricultural land and damage to infrastructure. This graphic shows the Nile Delta region as it is today (2002), the area as it would appear with a 0.5 m sea level rise, and the area as it would appear with a 1.0 m sea level rise.

Lake Chad - decrease in area 1963, 1973, 1987, 1997 and 2001 Lake Chad - decrease in area 1963, 1973, 1987, 1997 and 2001
Straddling the borders of Nigeria, Chad, Niger and Cameroon in West Africa, Lake Chad has been a source of freshwater for irrigation projects in all these countries. This graphic traces the shrinkage of Lake Chad and changes in vegetation from 1963 to 2001. It includes maps of the lake from 1963, 1973, 1987, 1997 and 2001. Climatic changes and high demands for agricultural water are responsible for the lake's shrinkage.

Who is involved? (The making of international legislation) Who is involved? (The making of international legislation)
Recognizing that industrial society must fix this major flaw in the system, governments and many forward-looking companies started exploring solutions as early as the 1970s. The strong activism of civil society organizations and the interest of the media in cases of toxic waste dumping were central in bringing the issue on the international agenda. By the 1980s, the international community launched treaty negotiations under the auspices of the Un...

Distribution of reindeer population in the Barents Region Distribution of reindeer population in the Barents Region
The rendeer population of the Barents region is broken down into 5 distinct groups to show and their range. The 5 types are: Svalbard, wild, wild forest, domesticated and wild, and domesticated or semi-domesticated. (Please note that the The Barents Euro-Arctic Council has expanded the membership since 1998)
