Answer: Global warming is the term used to describe the rising of the average temperature on Earth. It has to do with the overall climate of the Earth rather than the weather on any given day.
Global warming is a very complex subject. Some scientists disagree as to what caused the rise in temperatures that occurred during the end of the 20th century. Things that can have an impact on global warming include the natural temperature fluctuations of the planet, greenhouse gases such as carbon dioxide, volcanic eruptions, and increased solar activity. Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks."
Answer:
rise of temperature of the atmosphere of earth called global warming. it's main causing gas are Methane co2 CFC.The radiated heat is absorbed by these gases and restored instead of going to space so temperature goes on increasing
