Climate changes and the subsequent global warming are capable of causing significant, long term and possibly irreversible effects on a regional, continental and global level. While some of these effects are a direct consequence of global warming, there are also certain indirect effects of this phenomenon. Some significant effects of global warming include melting of polar ice caps, economic impart, changes in the timing of seasonal patterns in ecosystems and expansion of tropical diseases.

Melting of polar ice caps occurs as a result of increased temperatures in the earth’s environment. As a result, one can observe incidents such as raising sea levels, retreating of glaciers and shrinking of arctic and Antarctic regions. Polar ice caps and glaciers are an important source of fresh water on this planet. If they melt, there will be a severe shortage of drinking water on the earth. Other major effects of global warming include increased incidences of stronger hurricanes and greater probability of droughts and heat waves, a phenomenon known as El Nino effect. Global warming can cause greater spread of tropical diseases such as malaria. This is because till now colder regions were not conducive for the spread of tropical diseases. Once these countries get warmer due to global warming, they will no longer be resistant to these infections.
