The Negative Effects of Global Warming

Assalamualaikum and good evening to Mdm Hazwani and my fellow friends, I am WanMuhamad Taufik Bin Wan Mustafa from Ijazah Usuluddin Group 1. Today I would like to talkabout the negative effects of global warming. As we all know, global warming causes manynegative results to the world and human health. Global warming is the rise in the average

temperature of earth`s atmosphere and ocean.For your information, global warming is usually happens due to human-made activities.

Have you realized that there are too many disasters that happen nowadays? We does not reallyfeel the impact on us until they come. May be our new generation will not be able to see thisworld as we see now. There are too many serious negative effect of global warming that occursas we all know from television, radio, newsletter and so on. Three of the negative effects ofGlobal Warming are facing drought and floods, raising sea level and threatening weather.

The first of the three negtive effects is facing drought and floods. Based on Macmillan Englishdictionary, drought is a long period of time when there is little or no rain and crops die.When thetemperature rise, water evaporates will also be quicker.The evaporated water is likely to condense toform clouds and fall as rain or snow. However, the rainfall will not be evenly distributed. In dry areaswhere water is scarce and the plant life depends on water from lakes and rivers, the increasedevaporation is likely to worsen the dry conditions and a drought occurs. Therefore ,crops will die andfamine might be the result as food production will decrease because of crops not be able to adapt to theextreme conditions. In wet areas, more water will be evaporated and will eventually fall in these areasas rain or snow. This might result floods.

The second of the three negative effects is raising sea level. A rise in sea level is one of the best-known consequences of global warming. As we all know, there is about 97% of earth`s water is in theoceans already. As global temperatures have risen, some of this ice has begun to melt. As land ice meltsand the meltwater runs down to the sea, it obviously adds water to the oceans and raises sea levels.Furthermore, those who live at low-lying coastal areas will flood and maybe even be submerged. Baseon a research of Geophysical Research letter by Georetski and K.P Kolterman (2007), All most 2/3 of theworld`s population live within 150km of the coastline. Therefore, millions of homes and lives will be lostas coastal areas go underwater. Therefore, many small islands are also in danger. The sea water willflood farm areas and damage crops and we will lose our food supply.
