What effect do carbon dioxide methane and a few other atmospheric gases have on earths temperature?

Answer 1

Gases such as Carbon dioxide and methane cause the atmosphere to absorb more of the suns heat, hence warming the atmosphere. A warmer atmosphere cases changes like less arctic ice, fewer glaciers, which case less reflectivity of the suns heat, the melting water raises sea levels. It can also cause climate changes which result in smaller winter snow packs, which means less water for the summer. On the other side a warmer climate can cause more severe storms much as El Nino does.

Answer 2

Generally, these molecules tend to hold heat, so as the amount of these molecules increase in the atmosphere, Earth's temperature would increase. While I believe humans can affect global climage, it's not a simple process. As the amount of these molecules increase in the atmosphere, other chemical processes change, so the process has been difficult to accurately predict.

Answer 3

All these greenhouse gases are responsible for global warming, the serious raising of earth's temperature, which is causing climate change.

Answer 4

Greenhouse gases like water vapour, carbon dioxide (CO2) and methane (CH4) raise the temperature of the atmosphere.

Answer 5

Carbon dioxide is a greenhouse gas. It traps heat radiated up from the warm surface of the earth. So more carbon dioxide means a warmer earth.
