๑.. Global Warming Effects ..


Global warming has many effects on the earth and these effects are ranging from big disasters to few effects. For example, it increases the risk of flooding from high sea levels and heavy rain. Furthermore, the glaciers in the north of the earth are melting and this is also a big disaster. It could kill many humans and flood all coastal cities. Statistics show that many frozen areas in the north are melting daily and raising the level of the sea. In addition, the natural disasters in the USA in the last century such as Katrina were stronger and more dangerous due to the change in the climate. Finally, it is obvious that all of these effects are dangerous to the earth and alarming us to be serious with this problem.




๑.. Ice Melting ..



Scientists proved that the sea level has risen by about 15-20 cm over the last century due to melting ice in the north, and also from ice floating on the Arctic Ocean. All these effects are increasing the sea level and may sink some parts of the coastal lands. This means a lot of humans will lose the source of food and shelter. In addition, for years the icebergs in the North Pole and the South Pole are melting and the scientists’ estimate that at the end of this century the North and South Pole will be without any ice and snow during summer. All in all, from all these results above, ice melting will be danger to human life and may delete several coastal cities and make it underwater.
