At present man-made greenhouse gases, carbon dioxide (CO2) and methane, are adding to the greenhouse effect. The natural carbon cycle is unable to cope with the extra CO2 which remains in the atmosphere gathering heat, and causing global warming.

Less than 1% of the gases in Earth's atmosphere are called greenhouse gases. Even though they are not very abundant, these greenhouse gases have a major effect.

Carbon dioxide (CO2), water vapor (H2O), methane (CH4), nitrous oxide (N2O), and a few other gases are greenhouse gases. They all are molecules composed of three or more atoms, bound loosely enough together to be able to vibrate when they absorb heat. Eventually, the vibrating molecule will emit the radiation again, and it will likely be absorbed by yet another greenhouse gas molecule. This process is called the greenhouse effect and keeps heat near the Earth's surface.

All of the green house gases that are mentioned in the above answer are not necessarily man made. They are all natural gases in our environment. The jury is still out on whether we make enough to cause severe climate change as is claimed.

Why are increased greenhouse gases not good for the earth?

Increased greenhouse gases are not good for the earth as they are building up in the atmosphere and causing global warming. Global warming is causing climate change which is already affecting many people around the world.


How are excess greenhouse gases affecting the temperature of earth's atmosphere?

Greenhouse gases help keep the earth's temperature at a comfortable level suitable for human existence. When we increase the atmospheric concentration of greenhouse gases above their natural level, this leads to global warming, in other words higher average temperatures across the globe.
