EVIDENCE OF GLOBAL WARMING
Only a person who has been away from our planet for some time would claim that global warming is not happening. The evidence shows abundantly on all the continents of the world. Several aspects of climate have been affected. For instance, in the temperate zones, the summers are warmer and more humid. Droughts are more frequent, particularly in Africa. Rainfall and snowfall are more intense and, in some cases, quite destructive. Snow (or ice) cover on mountaintops is diminishing compared what was there in 1950. There is scientific evidence showing that ice in the polar zones is melting at a faster rate.
Below is a general continent-by-continent evaluation.

In June 2006, an international effort was mounted to rescue people stranded by major flooding of the Zambezi River. Ethiopia, which experienced many droughts, suffered another major one during the 2002–2006 period.
Several major lakes on the African continent are drying up. Lake Chad is the most vulnerable, as it is so close to the Sahara Desert.
Lake Nakuru in Kenya is surprisingly, one of the few lakes in Africa that are rising.. This lake is a significant habitat for flamingos and other rare tropical birds. The shallowness of Lake Nakuru creates an ideal environment for plankton and other organisms that form the food supply for the flamingos. Unfortunately, the planktons in question do not thrive in deep waters. As such the increased water lever have a negative impact on bird and perhaps other wildlife habitat.
The construction of the Aswan Dam created Lake Nasser. This lake sits in an area where rainfall is rare, so the rate of its evaporation is perhaps higher than that of African lakes in cooler areas. Besides this, Egypt has tapped into the lake and created smaller lakes in the Sahara Desert to supply water to agricultural projects. The evaporation of water from Lake Nasser and the other lakes created in the Sahara could be significant factors in moderating …show more content…
Lake Chad, which has been in crisis for almost a century, is retreating even faster. It may disappear altogether by 2100. (Source – www.pixabay.com)
Figure 5. The snowcap on Mount Kenya has diminished and has virtually disappeared within one generation. This has implications on rivers that were fed by ice on top of the mountain during seasons of drought. The mountain had a permanent snowcap in 1900 when it was first seen by European explorers.
