As far as radiative forcing (it's ability to trap radiation, and therefore warm the Earth via greenhouse effect), methane is 21 times stronger than CO2. However, Methane's lifespan in the atmosphere is only about 12 years, whereas CO2 gets complicated due to all the cycles it participates in but is generally on the order of a century. Additionally, there's a whole lot less methane in the atmosphere, so in the end, CO2 is doing more to warm the Earth than methane is.

How many times worse is methane compared to carbon dioxide?

Methane is twenty-one times more powerful a greenhouse gas as carbon dioxide.


Do vegetarians produce most carbon dioxide?

No, meat eaters are responsible for more carbon dioxide than vegetarians. Cattle belch a lot of methane, which is a greenhouse gas more powerful than carbon dioxide.


How strong is methane on its effect on global warming?

Methane (CH4) is a greenhouse gas twenty times more powerful that Carbon dioxide (CO2).


Is carbon dioxide the only gas causing global warming?

No, but carbon dioxide is the main gas. Methane is the next most important gas causing global warming. Methane is more than twenty times more powerful than carbon dioxide, but not so plentiful. Methane comes from cattle, as well as from melting lakes and tundra.


What is burning methane?

If you mean is burning methane comparatively better than releasing it into the atmosphere, then yes it is. Methane is a greenhouse gas, twenty-one times more powerful than carbon dioxide. If methane is released into the atmosphere it works as a greenhouse gas. If it is burnt, it released carbon dioxide instead. Carbon dioxide is also a greenhouse gas, but it is not as powerful as methane. So burning methane is good for the environment.

How are greenhouse gases produced and are they more or less of a problem than carbon dioxide?

The greenhouse gases that are causing global warming are carbon dioxide (CO2) and methane (CH4). This carbon dioxide comes from burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity. The methane comes from rotting organic material in landfills, pig and cattle farms and from melting tundra and lakes. Methane is a greenhouse gas twenty-one times more dangerous, than carbon dioxide, but there is much more carbon dioxide.


How do landfills contribute to global warming?

Landfills typically release methane, which is a greenhouse gas produced from rotting organic matter, like food scraps and garden waste. Methane is a greenhouse gas twenty-one times more powerful than carbon dioxide.

How can you reduce the impact of burning methane on global warming?

We can stop burning methane. Actually burning methane is better than letting it escape into the atmosphere. Methane, when burnt, emits carbon dioxide, a powerful greenhouse gas, but methane, when released into the air, is twenty-one times more dangerous.
