According to a recent study, methane is up to 100 times more potent a greenhouse gas than carbon dioxide. And to explain why, we have to begin not on earth, but in space. All energy on earth comes from the sun, mainly in the form of light. “Light is energy,” says Neil Donahue, an atmospheric chemist at Carnegie Mellon University.

Methane is a far more potent greenhouse gas than CO2, even though it only lasts about a decade in the atmosphere, whereas CO2 persists for a couple of centuries. A continued rise in the amount of methane in the air could easily cancel out any near-term progress we make in reducing CO2 emissions.

(In case someone needs to refer those, here are a few useful links- Greenhouse effect, Greenhouse gas) So I'll continue with the reasons, a green house gas is a gas which can absorb and emit Infrared radiation, which Methane does effectively.

Because methane is both a powerful greenhouse gas and short-lived compared to carbon dioxide, achieving significant reductions would have a rapid and significant effect on atmospheric warming potential.

Methane (CH 4) is the second most important greenhouse gas. CH 4 is more potent than CO 2 because the radiative forcing produced per molecule is greater. In addition, the infrared window is less saturated in the range of wavelengths of radiation absorbed by CH 4, so more molecules may fill in the region.

⚡️
Methane is a one-carbon compound in which the carbon is attached by single bonds to four hydrogen atoms. It is a colourless, odourless, non-toxic but flammable gas (b.p. -161℃). It has a role as a fossil fuel, a member of greenhouse gas and a bacterial metabolite.

Is burning methane bad for the environment chart?

⚡️
However, methane that is released into the atmosphere before it is burned is harmful to the environment. Because it is able to trap heat in the atmosphere, methane contributes to climate change. Although methane’s lifespan in the atmosphere is relatively short compared to those of other greenhouse gases, it is more efficient at trapping heat than are those other gases.

⚡️
Despite carbon dioxide’s comparatively low GWP among major greenhouse gases, the large human-caused increase in its atmospheric concentration has caused the majority of global warming. Likewise, methane is responsible for a large portion of recent warming despite having a GWP much lower than several other greenhouse gases because emissions have increased drastically.

Faq: what is carbon dioxide considered the main greenhouse gas?

Why carbon dioxide is a greenhouse gas? A carbon dioxide molecule consists of two oxygen atoms and one carbon atom. When the carbon atom moves along the chemical bond towards either one of the oxygen atoms, or moves up and down relative to the oxygen atoms, the relative distribution of the charges will be altered and hence carbon dioxide can absorb infrared radiation.

How do greenhouse gases absorb heat?

A real greenhouse traps heat because its glass stops the warm air inside from transferring heat to the colder surrounding air. Greenhouse gases don’t stop heat transfer in this way, but as this piece explains, in the end they have a similar effect on the Earth’s temperature.

How is methane bad for us?

Methane is nontoxic on its own but can become lethal when it combines with another gas. Methane causes asphyxiation by displacing oxygen. It may produce symptoms of dizziness and headache , but these often go unnoticed until the brain signals the body to gasp for air. This happens too late, and the individual collapses.
