An Introduction to Climate Change Phenomenon

Long-term change in the average weather patterns of the earth’s local, regional, and global climates is called climate change. These changes have a broad range of observed effects. Climate change is mainly linked to changes, which the scientists observed over the current decade and those that are projected to be happening, mainly as a consequence of human behavior, in all the continents. Other reasons for climate change include greenhouse effect, global warming, urbanization, and deforestation. Due to these impacts of climate change, temperature rise, increase in CO2 concentration, seawater rise, and ocean acidity also took place in the past. The earth’s ecosystem is rapidly changing due to climate change. In this book chapter, we elaborate the reasons for the natural greenhouse gas emissions and the role of various stakeholders in the phenomenon of climate change.
