Green House Gases

Abstract

Changes in weather patterns over decades or longer periods of time are referred to as climate change. Natural and human forces both contribute to climate change. Since the Industrial Revolution, humans have contributed to climate change through emitting greenhouse gases and aerosols, as well as changing land use, leading global temperatures to rise. More storms, floods, droughts, and rising sea levels may result from increasing global temperatures and the melting of ice sheets, sea ice, and glaciers. The sun's rays supply energy to the whole world. GHGs are required to trap heat and maintain a temperature that permits life to flourish on the planet. The greenhouse effect is a natural and necessary occurrence for life on Earth to survive. If the greenhouse effect did not exist, the world would be around 33°C cooler right now. Humans have contributed to the increase in atmospheric GHGs via rising fossil fuel usage and deforestation in recent decades. Increased GHG emissions have been the primary cause of global warming during the last century.
