What causes climate change?

What causes climate change? Climate changes are caused by changes in the total amount of energy from the Sun that is kept in the Earth's atmosphere.1This change in energy is then distributed around the globe by winds, ocean currents, and other mechanisms to affect the climates of different regions.
Both natural processes and human activities can change the rate of energy absorbed by the atmosphere.1 Factors that can affect climate change can be divided between feedback and forcing processes. Forcing processes are external factors that can cause changes directly to our climate, where as feedback processes amplify or diminish the effect of climate forcing.2

What causes climate change: Forcing

A forcing process changes the proportion of incoming solar radiation and outgoing infrared radiation that is kept in the Earth's atmosphere and so changes the amount of energy within global weather patterns. Forcings are external processes that affect the climate system. Examples of forcings include volcanic eruptions and increased greenhouse gas concentrations
 The Earth's climate has never been completely static and in the past the planet's climate has changed due to natural causes but the climate changes seen today are being caused by the increase of carbon dioxide and other greenhouse gases in the atmosphere by humans.
