Climate Change and Global Warming: Explained in Simple Words for Beginners

The term climate change is used to denote the long-term changes in the weather patterns in a given region. Another term often interchanged with climate change is global warming. Global warming is formally defined as a rise in Earth's temperature that persists for a decade or longer. There could be several causes for climate change, but the biggest one is the rising concentration of greenhouse gases. Simply put, greenhouse gases are those gases in our atmosphere that trap heat. Some examples include carbon dioxide, methane, chlorofluorocarbons, nitrous oxide and ozone. Natural sources and human activities both result in the emission of greenhouse gases. One of the most common ways these gases get released into the atmosphere is through the burning of fossil fuels. Burning coal or oil to run industrial processes or giant factories increases the concentration of atmospheric carbon dioxide. Indeed, fossil fuels' contribution to greenhouse gas emissions is the largest, in the range of 70- 80% of total emissions. In this video, we explain, in simple terms, climate change and global warming and what we can do as a community and individually to save Earth from climate change.
