This essay provides an overview of climate change, beginning with an introduction to the observed warming of the Earth's surface since the Industrial Revolution and highlighting the role of greenhouse gases (GHGs) in trapping heat. It explores the causes of climate change, emphasizing human activities such as fossil fuel use and industrial processes, while also acknowledging the role of solar variability. The essay then examines the impacts of climate change, including both potential benefits in some areas and adverse effects such as agricultural decline and sea level rise, alongside the associated risks of sudden and unexpected changes. It discusses mitigation strategies, focusing on reducing GHG concentrations through economic adjustments and changes in consumption patterns. Finally, the essay presents a position argument, supporting the scientific evidence on climate change and advocating for urgent action to reduce GHG emissions.
