Vital Climate Graphics Africa
This set of 25 graphics focuses on the special challenges that Africa faces due to expected long term changes in climate. The graphics indicate that temperature rise in Africa corresponds to global temperature rise, and that adverse impacts including extremes, are spread across the diverse environments of Africa, putting a huge proportion of Af ...

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, Austral...

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 b...

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...

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 na...

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 sho...

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...

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 cha...
