How does the greenhouse effect affect the earth?

Answer 1

It causes the atmosphere to get warmer.

Answer 2

The earth is surrounded by an atmosphere of air, made up of a number of gases. These gases form a 'blanket' which prevents all the sun's heat (infrared radiation) from reflecting back into space. If this greenhouse blanket was not there the surface of the earth would be about minus 18 degrees C (0ºF), instead of its present average temperature of 15 degrees C (59ºF). So this natural greenhouse effect is very useful.

The gases that keep the earth warm are called greenhouse gases. The most important gas, causing about 75% of the natural greenhouse effect, is water vapor. The next most important is carbon dioxide.

About 200 years ago humans started pumping carbon dioxide into the atmosphere, when the first factories began. Today the concentration of carbon dioxide is 35 per cent greater that it was in the 18th century. We have increased other greenhouse gases too, like methane, nitrous oxide and ozone.

These increased amounts of greenhouse gases trap more infrared radiation and the earth's lower atmosphere is warming up. This is known as the enhanced greenhouse effect and is causing global warming, which, in turn, is causing climate change. 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.
it causes global warming

Answer 3

the greenhouse effect influences the earth by cause global warming. The reason why is because the greenhouse effect, traps heat in our atmosphere, causing the earth to heat more than usual.

Answer 4

The "greenhouse effect" refers to trapping heat. Green houses let light shine through all the walls and ceilings, through translucent glass or plastic. This radiation is absorbed and emitted in the infrared (heat) spectrum, but remains inside the green house.

Many scientists believe atmospheric CO2 concentrations of 350 ppm (parts per million) would be sustainable. In other words, below 350 ppm earth's temperature would tend to remain constant. Above 350 ppm, however, there may be a "runaway" greenhouse effect, in which high temperatures cause trapped methane gas releases, which spurs higher temperatures and more methane gas. After a few centuries earth becomes transformed into a paradise much like Venus. No disease, war, famine, poverty, life etc.
