Fresh water will become scarcer as mountain glaciers disappear, particularly in Asia and parts of North America (Holli Riebeek 2007).

Intense droughts could also give rise to malnutrition. As tropical temperature zones expand, there will be the outbreak of infectious diseases like malaria. Invariably, the poorest people who are incapable in fencing off the climate change are expected to be hit hardest. Flora and fauna that cannot migrate or withstand the rising temperature will be eventually in the brink of extinction. Warmer temperatures have altered the growing season in parts of the globe. With the happening of global warming, the ecological balance of the nature has been affected. Significantly, the erratic weather happens as a consequence of global warming should take into consideration. Darfur and Niger are the nations that suffering from severe drought due to the desiccation of Lake Chad. Owing to the facts that global warming is not only increasing the precipitation worldwide but also relocating the precipitation, global warming paradoxically causes flooding and drought.

He revealed that the warmer oceans will intensify the storms, hurricanes, tornados and typhoons. Besides, Al Gore (2007) unfolded that the ten hottest years have been occurred in the last 14years. Prediction proclaimed that Bangladesh or some low-lying areas, including Florida, California, and Maldives island might most probably disappear underwater in the future (Chris Woodford 2006). Melting glaciers in Antarctica are also feeding more water into the oceans and contributing to the substantial rises in sea-level.

According to the Arctic Climate Impact Assessment (ACIA), roughly 8 percent of ice in the Arctic has been reduced over the past 30 years. Consequently, the heated water occupies larger volume, causing the sea level rises. The rising of temperature due to global warming warms up the ocean and Earth. Global warming has the potential effect on the average and extreme temperature as well as precipitation.
