Definition

Most climate scientists agree the main cause of the current global warming trend is human expansion of the 'greenhouse effect' - warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. Long-lived gases, remaining semi-permanently in the atmosphere, which do not respond physically or chemically to changes in temperature are described as 'forcing' climate change whereas gases, such as water, which respond physically or chemically to changes in temperature are seen as 'feedbacks'.
