why do the atmosphere is changing
Answers
Answer:
Human activities are also responsible for atmospheric change. ... For example, the burning of fossil fuels is producing a worldwide increase in the atmospheric concentration of carbon dioxide, which transmits visible light but traps infrared radiation near the Earth's surface.
Explanation:
he Earth's atmosphere is changing. Scientific measurements have documented shifts in chemical composition throughout the lower atmosphere, as well as substantial alterations in chemical composition in the upper atmosphere. Both of these findings have important implications for terrestrial life and human societies.

Both of these findings have important implications for terrestrial life and human societies.Natural and Human InfluencesSome of these changes have a natural origin. Variations in the intensity of solar radiation influence the energy balance, chemistry, and dynamics of the atmosphere, as do fluctuations in the intensity of the solar wind and of cosmic rays from space. Volcanic eruptions inject dust, ash, and a variety of chemical compounds into the atmosphere. Such natural events tend to be either periodic or episodic; their effects, while often dramatic, normally pose little threat to the equilibrium of the global Earth system.

By contrast with natural processes, however, these activities are generating long-term trends which, if continued, may lead to large and irreversible effects. For example, the burning of fossil fuels is producing a worldwide increase in the atmospheric concentration of carbon dioxide, which transmits visible light but traps infrared radiation near the Earth's surface. This so-called "greenhouse effect" will produce a global warming trend. If atmospheric carbon dioxide continues to increase at the present rate, modeling studies estimate that the global average surface temperature will rise some 2deg. Celsius by the middle of the next century--a climate change greater than any ever experienced by organized human societies
