Global Climate Change and Human Activity

The question that is in the minds of many people around the globe is the debate between natural causes, and human activities being the main cause to the negative changes in the global climate. Natural causes like volcanic eruptions, the changes in the sun’s radiation, and the ocean current shifts noticed are contributing to the global climate change. In addition, the human activities such as the burning fossil fuels, and the cutting down of trees [forests] so as to create land to cultivate and rare cattle affect the climate change. The human activities that are done affect the global climate that the natural causes which has led to global warming in the atmosphere (Oxlade, 2003).

The human activities that are undertaken such as burning of fossils release some greenhouse gases such as carbon dioxide, Methane, and nitrous oxide into the atmosphere. The greenhouse effect is created in our atmosphere. When the sun's energy heats up the Earth by warming it, our planet radiates some of this heat that was heating the surface back out towards the outer space. Some of the gases that have accumulated in the atmosphere act like the glass existing in a greenhouse, which allows the sun's heat to get in without escaping by getting trapped. Some of the greenhouse gases exist but lately the human activities are releasing an additional of high levels of other greenhouse gases thereby enhancing the greenhouse effect (Haldar, 2011).

The world's highest ranked scientists in the field of climate have come to a common conclusion that there is global warming throughout the world. They believe that the cause of the global warming is because of the high levels of greenhouse gases that are being released to the earth atmosphere from the human activities d...
