Climate Change/Global Warming and Its Impacts on Parasitology/ Entomology

Abstract

Climate change and global warming are important phenomena and do not mean the same thing as is wrongly conceived by some individuals. However, the link between the two is strong and one, global warming is strictly an average increase in the temperature of the atmosphere near the earth’s surface and in the troposphere, while the other, climate change is more diverse and refers to any significant change in measures of climate such as temperature, precipitation, or wind lasting for a long period of time usually several years. Climate change could thus be an increase or decrease in temperature. The most important of the two terms which is under spotlight is global warming, an increase in temperature which has been blamed largely to greenhouse effect. There can no longer be any doubt that the earth’s climate is changing. It is now obvious that even the most hardened sceptics are starting to waiver in their convictions. Climate has been thrown completely out of kilter and each day brings fresh proof such as frequent and more violent cyclones in the Caribean, floods in Africa, the Philippines, the gradual sinking of Islands in the Pacific, heat waves in Europe and the melting of glaciers. There is increase in global average air and ocean temperatures, widespread melting of snow and rising global average sea level. Impacts of global warming include the emergence and re-emergence of some parasitic infections and diseases.
