Critically evaluate the possible causes and effects of the phenomenon known as Global Warming Global warming refers to the observed increase in the average temperature of the Earth’s atmosphere and oceans in recent decades, which is directly related to an increase in the concentration of greenhouse gases in the atmosphere leading to an increase in the amount of infrared or thermal radiation near the surface. This essay will evaluate the causes and their resulting effects of the phenomenon known as ‘Global Warming’. Interestingly, there is a very continuous debate as to how significant human, or economic intervention is to affecting Global warming, and how much of it can be put down to natural causes. Nonetheless, there are clear pieces of evidence provided that suggests global warming is down to anthropogenic causes, and that of economic activity. Firstly, the mass amount of deforestation that takes place across the world today can have drastic effects on global temperatures. For example, vegetation works in harmony with human life as they help to keep the balance of carbon dioxide in the atmosphere by absorbing it, with the growing number of trees being cut down, and an ever increasing population, the balance is being lost. As a result of this, there is a noticeable increase in CO2 within the earth’s atmosphere. The Amazon for instance; absorbs approximately 35% of the worlds annual carbon dioxide emissions and produces over 20% of the worlds oxygen. In addition to this, the Amazon is home to more than half the world’s estimated 10 million species of plants, animals and insects that’s are rapidly losing their habitats. Mass deforestation can cause huge climatic problems in the future, for example, it has been estimated that there will be an increase in temperature of around 2-3 degrees Celsius by 2050 if deforestation continues to occur at its current rate. Environmentally, this causes great damage to the environment as the earth’s natural resources are being...
