Anthropogenic Contributions to Climate Change
(Sometimes also known as “human climate forcing”). Simply put, the contributions that humans make to climate change. For example, the burning of fossil fuels (like coal and gas) produce large amounts of greenhouse gases like carbon dioxide.These gases warm up the atmosphere (global warming) and contribute to climate change. Anthropogenic contributions to climate changes are distinct from natural climate changes where human activities play no role at all. An example of natural climate change - volcanoes can spew ash miles into the air, blocking light from the sun and lowering the earth’s temperature. Since climates are very complex systems and human activity is widespread throughout the biosphere, usually the two types of climate changes – natural and anthropogenic - are intertwined. They can also interact in feedback loops.
