Global Warming

Global warming is the one of the biggest challenges that the planet may be facing today. Global warming is the increase of the temperature in the earth’s surface air. It tends to be one of the greatest factors that are being discussed. There are many trends that demonstrate global warming has a great impact on the rise of the sea levels, ice caps that are melting and the changes in the climates worldwide. Because of this it can be a problem to all of the things living on earth. During the past centuries the temperatures has risen significantly, scientist have shown that the increases since the middle of the 20th century has caused a rise in the greenhouse gas concentrations because of human activities. Most scientists have agreed that the planets temperature has risen .5 degrees since the 1900’s and will continue to rise. (Gore, A. 2006). Within the last 100 years from 1983, 87, 88, 89, and 1991 these were the warmest year’s scientist say. Of the six years stated above 1991 was the 2nd hottest year of past centuries. Because of the rise of the temperatures is capable of being felt all over the world, scientist has shown that within the next hundred years the temperatures will rise from 1.4 to 5.8 Celsius. Our lives and the earth are showing is signs of disasters in the form of cyclones, landslides, and floods because of the imbalance between us. If we keep the imbalances rising, then this will cause a question mark to be put on this planet. The thing that is causing a warming effect on the earth’s surface is Carbon Dioxide. (Gore, A. 2006). Carbon dioxide increases the water evaporation into the atmosphere, and since water vapors are considered to be a greenhouse gas it has caused more warmth on the earth’s surface. The warmer it gets the more vapors that will be evaporated; Carbon dioxide levels are going to rise in the future because of the ongoing burning of fossil fuel and the...
