Abstract: Climate change has become a widespread topic in recent years. It is a problem resulting from the emission of greenhouse gases that greatly affect our environment. Climate change is the periodic modification in Earth's climate caused by changes in the atmosphere as well as interactions between the atmosphere and various other geological, chemical, biological and geographical factors within the Earth system. Climate change includes both global warming and large-scale changes in weather patterns driven by human-induced emissions of greenhouse gases. The question arises whether the problem of climate change is caused by human activities or is a part of nature. Although there have been previous periods of climate change, since the mid-20th century humans have exerted unprecedented influence on the Earth's climate system and have caused climate change on a global scale. Climate change may make weather patterns more difficult to predict. These unpredictable weather patterns may make it difficult to maintain and grow crops, further weakening the economic status of developing countries dependent on agriculture. As a result of rising temperatures due to climate change, ice in the Polar Regions is melting at a faster rate, which is causing global sea levels to rise. It is damaging sea coasts by increasing flooding and erosion. The biggest driver of global warming is the emission of gases that cause the greenhouse effect, of which more than 90% are carbon dioxide and methane. Climate change poses risks to the survival of species on land and in the ocean. These risks increase as temperatures climb. Exacerbated by climate change, the world is losing species at a rate 1,000 times greater than at any other time in recorded human history. One million species are at risk of becoming extinct within the next few decades. At present, the major reason for the rapid climate change is the human based activities which are responsible for threatening the existence of mankind. This paper discusses and compares the various factors contributing to climate change. It also points towards some of the effects and solutions of climate change. The study also sheds light on developing mechanisms to prevent or insure against climate change.
