Global Warming Essay

Global warming is the ‘global warning’ of the century. It is a major atmospheric issue all over the world. Global warming is the process of continues increase in the average temperature on Earth, including surface, oceans and atmosphere. However, the change of climate is a normal process of the Earth’s cycle. The issue that concerns scientists is that human activities accelerates the heating of our planet.

Our planet’s surface becomes hotter year by year by trapping the Sun’s light which causes an increase of the percentage of atmospheric carbon dioxide in the air. The energy is being absorbed mostly because of the greenhouse effect due to the high amount of greenhouse gasses in our atmosphere.

Starting from the second part of the nineteenth century scientists have started documenting the climate in general and average temperatures all over the world. Since then people are constantly arguing about the question is the climate change a myth or it is not. However, different researches show that 97 percent or more of actively publishing climate scientists agree: “climate-warming trends over the past century are extremely likely due to human activities” (Cook, 2016). The average temperature has risen by approximately one degree Celsius for the past hundred years, according to the Environmental Protection Agency (EPA). A such temperature shift may sound as a minor change, however, the increase has already caused numerous changes in planet’s look.

Scientific evidence for warming of the climate system is unequivocal. Global warming has dangerous implications for our planet. It is unbelievable how one degree can cause so many problems. For example, global sea became around 17 centimeters higher for the last hundred years, moreover, the last decade has even doubled the number century (Church and White, 2006). Rising sea levels threaten entire countries on low-lying islands in Oceania. The Greenland and Antarctic ice sheets have decreased in mass. According to the NASA’s Gravity Recovery and Climate Experiment research, Greenland is losing 36 to 60 cubic miles of ice per year. There is no doubt that “warming of the climate system is unequivocal” (Church and White, 2006).
