How is the temperature of the Earth controlled by carbon dioxide?

Answer 1

The Greenhouse Effect and Global Warming.

Carbon dioxide is what we call a greenhouse gas. Too much of it in the atmosphere and the sun's heat gets trapped and global average temperature rises.

Earth itself releases lots of carbon dioxide via vegetation and plants and also oceans. But not only does earth emit carbon dioxide, it also captures it again and stores it, again via vegetation, plants and the oceans. This process is called the Carbon Cycle and in a way it enables earth to always keep some sort of balance in the amount of carbon dioxide in the atmosphere.

Humans also emit carbon dioxide, primarily by burning fossil fuels such as coal, oil and natural gas. But we humans only emit carbon dioxide to the atmosphere, we do not capture and store it again as nature does. This has an effect on the natural balance mentioned earlier and, as a result, drives global average temperatures up (which is commonly known as Global Warming).

A: The world is like a greenhouse, and carbon dioxide and other greenhouse gases such as methane act as the glass. The gases cover the earth and stop some heat from getting back out into space. The more CO2 we have in the earth then the more heat will be trapped, which causes the world to heat up. This is made worse by deforestation because plants take in CO2 and without them, less carbon dioxide is taken in, which in turn traps more heat.
