Extreme Weather
Extreme weather and natural disasters occur all the time all over the world. These include heat waves, river and coastal flooding, droughts, landslides, storms, hurricanes, tornadoes. However, if the Earth warms up because of man-made pollution, some of these extremes may become more intense and may occur more frequently. This may have a negative effect on society as these events damage homes and villages and can lead to loss of life.
Global warming is expected to increase the amount of moisture in the air because more water is evaporating from ponds, rivers, lakes, and oceans. In many places this will lead to an increase in rainfall causing more frequent floods and landslides. However, some places may receive less rainfall, particularly those parts of the world that are already dry, like the deserts and semi-deserts.
If the amount of really bad weather increases in the future we must learn how to predict and cope with it. Unfortunately, the poorest and most vulnerable societies in the world will be the least able to cope.
