What does Global Climate Change mean
Answers
Answer:
Global climate change is a change in the long-term weather patterns that characterize the regions of the world.
The greenhouse effect is a warming process that balances Earth's cooling processes. During this process, sunlight passes through Earth's atmosphere as short-wave radiation. Some of the radiation is absorbed by the planet's surface. As Earth's surface is heated, it emits long wave radiation toward the atmosphere. In the atmosphere, some of the long wave radiation is absorbed by certain gases called greenhouse gases. Greenhouse gases include carbon dioxide (CO2), Chlorofluorocarbons (CFC's), methane (CH4), nitrous oxide (N20), tropospheric ozone (O3), and water vapor. Each molecule of greenhouse gas becomes energized by the long wave radiation. The energized molecules of gas then emit heat energy in all directions. By emitting heat energy toward Earth, greenhouse gases increase Earth's temperature. Note that the warning mechanism for the "greenhouse effect" is NOT exactly the same as the warning mechanism of greenhouse walls. While greenhouse gases absorb long wave radiation then emit heat energy in all directions, greenhouse walls physically trap heat inside of greenhouses and prevent it from escaping to the atmosphere.

thank you
Answer:Climate change means the difference in the Earth's global climate or in regional climates over time. ... Climate change is about abnormal variations to the climate, and the effects of these variations on other parts of the Earth. Examples include the melting of ice caps at the South Pole and North Pole
