Greenhouse gases cause a rise in atmoshphere temperature and result in global warming
Answers
Answer:
A greenhouse gas (GHG) is any gas in the atmosphere that absorbs and emits radiation in the thermal infrared range. These are the fundamental cause of the greenhouse effect, which results in increased temperatures on Earth.
The greenhouse effect occurs as the gases reach Earth’s surface. As the short wave energy heats the surface, some of the longer wave energy radiates back into the atmosphere and back into space. Greenhouse gases absorb some of the energy and trap it in the lower atmosphere. Less heat radiates into space, and Earth is warmer.
Many greenhouse gases occur naturally. Carbon dioxide, methane, water vapor, and nitrous oxide are naturally present in Earth's atmosphere. Others, such as chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), are human-made.
Because of the Industrial Revolution atmospheric greenhouse gas concentrations have been rising over the last few centuries. Increasing population and dependence on fossil fuels for energy have resulted in a sharp rise in GHG emissions. While some GHGs do occur naturally, other human activity has interfered with the natural cycles that can moderate the effect of the increasing emissions.
