Explain the science behind global warming
assistant
Global warming is caused by the increase in atmospheric concentrations of greenhouse gases, such as carbon dioxide, which trap heat from the sun and prevent it from escaping into space. Human activities, such as burning fossil fuels, are the primary cause of an increase in these emissions, making global warming the result of human behavior. As the amount of heat-trapping gasses continues to increase from human activity, temperatures around the world rise, leading to changes in weather patterns and unusual precipitation. Higher levels of carbon dioxide also lead to ocean acidification, where more carbon dioxide is absorbed by the ocean, leading to changes in water chemistry and ultimately impacting marine life.
