Is Methane Responsible For Global Warming

Climate change remains one of the most heated and debated topics in scientific circles and beyond, with methane often being correlated to global warming. Evidence suggests that methane, the second most prominent greenhouse gas, may indeed be contributing to the rapid warming of our planet.
However, it is important to consider the full picture before drawing firm conclusions. Methane emissions arise from both natural and human sources, with some studies hinting that the two are equally responsible for the rise in global temperatures. Yet, others claim that anthropogenic outputs far surpass that of natural sources when it comes to emissions of this powerful greenhouse gas.
Methane’s short lifespan of just 10 to 12 years in the atmosphere is often cited as a positive; it dissipates faster than carbon dioxide, which remains in the environment up to a century. However, researchers point out that during its time in the atmosphere, methane has 80 times the potency of CO2 to warm the planet. A 2017 Nature study predicted that methane-driven warming could account for half the rise in temperatures that have occurred since 2018.
To combat the effects of climate change, methane emissions should be reduced. It stands to reason that in order to do this, the sources of these emissions must be better understood. A recent survey published in the journal Science of the Total Environment shows that when it comes to anthropogenic emissions, livestock such as cows and sheep are by far the biggest contributors, accounting for more than two-thirds of the total. This can be attributed to the fact that these animals produce the methane through their digestive system. Other contributors include agricultural and industrial processes, as well as the burning of biomass and fossil fuels.
Although it may well be that methane is the primary culprit for global warming, large-scale studies are still needed to reach a definitive conclusion. The NASA-funded Carbon Monitoring System suggests greater research is needed to understand the extent of methane’s contributions. Furthermore, finding methods to effectively predict future emissions, and curtailing current sources, are essential steps in the prevention of further climate change.
In order to best tackle the effects of climate change, a multifaceted approach is needed. Reducing global methane emissions will be an essential element in this, but only if done so deliberately and effectively. As with other elements of global warming, it is worth considering both natural and anthropogenic sources of methane, and learning detailed information about current levels and contributors is key. As climate change continues to be a pertinent global issue, it is both necessary and urgent for us to equip ourselves with comprehensive knowledge about the main contributors, in order to take the appropriate action.
