Disease Extensions of the geographical range and season for some organisms could result in increases of diseases like malaria, dengue fever and yellow fever. Air pollution and exposure to greater extremes in temperature could lead to a greater frequency of asthma and respiratory diseases. Ecosystems Scientists predict that composition and range of many ecosystems will shift as species respond to climate change. Research models project that a substantial fraction of the world's forests, and possibly up to two thirds, will undergo major changes. They say the species composiiton will change and some forest may disappear all together.
Deserts are likely to become more extreme and result in increased soil erosion.
Mountain glaciers could retreat and inland wetlands would be affected by global warming with resultant changes in habitat for the current species. Ice in northern latitudes will melt if the global climate warms as predicted Researchers suggest that there will be a myriad of other changes and even a few surprises. But both the scientists and environment campaigners say human impact on the climate can be reduced by a number of measures. Alternatives We could reduce energy consumption by making fewer journeys and using better insulation in our homes. This would lessen the need to burn coal and oil, and lead to reduced emissions of carbon dioxide and nitrous oxide.
