Global warming is an environmental phenomenon, which started in the late 19th century. It is characterized by increased atmospheric and oceanic temperatures. Global warming has had negative impacts on the costal communities.
According to David Suzuki, a renowned figure involved in global warming awareness, one of the effects of global warming to coastal communities is increased floods, which destroy the lives and livelihoods of coastal communities. The increased atmospheric temperatures, which characterize global warming causes the rate of evaporation of ocean waters to increase. Water in the coastal regions evaporates quickly, causing formation of frequent thick clouds, which fall back on the earth’s surface in form of rainfall. This causes heavy rainfall in the coastal regions, which causes frequent floods.
Suzuki says that the floods, caused by heavy rainfall in the coastal regions disrupt the livelihoods of the costal communities. The floods wash away their places of business, leaving them with no sources of income. Coastal communities largely depend on fishing and tourism for income. The floods make it impossible for tourists to visit the beautiful places found on coastal regions as well as enjoy the climate of coastal regions from the comfort of their hotel rooms in the luxurious hotels found along the coastal lines. Fishing is also disrupted because the increased waters make it unsafe for fishermen to undertake fishing activities. During floods, some people lose their lives, while others suffer from different diseases to water-borne diseases such as typhoid and cholera: common in flood-hit areas.
Global warming has many negative effects on the coastal communities. Suzuki identifies increased floods, which destroy the lives and livelihoods of people leaving in the coastal regions, as just one of these effects.
