WebMay 10, 2024 · Climate forcing occurs when the climate is affected by physical factors outside the climate system, such as volcanoes erupting or an increase in greenhouse gases. The difference between natural and human-caused climate forcing is apparent when considering Earth’s climate trends over the past 800,000 years.
