Methane emissions reach to its highest records, as reported by researchers. From the latest data recorded in 2017, researchers conclude that methane emissions have reached to great heights.
Since the industrial revolution, greenhouse gases have been remarkably rising. But it comes out that in the last decade methane emissions have recorded massive increase, like never before. The increasing number of industries were blamed before for this. But research suggests that the natural sources of emissions also play an important role here.
Sources for methane emissions
Humans may be a major reason for global warming and emission of harmful greenhouse gases, but in case of methane emissions, the natural resources are also a great factor. Fossil fuel emissions, emissions due to various chemical activities in the soil, decomposition of organic substances, emissions from microbes, from animal stomachs, emissions from wetlands, etc. are some of the major natural sources of methane gas emissions.
Among the human caused sources include various kinds of industrial emissions, emissions from petroleum industries. Methane is emitted by any activity related to petroleum, crude oil or any kind of natural fuel. Activities starting from production, processing till the distribution and transportation of natural gas/fuels, methane is emitted at every step. The process of waste management also contributes to methane emissions.
While we can control the human caused emissions to some extent, controlling natural emissions is still a very hard task.
Though, the amount of methane in the atmosphere is less than the amount of Carbon dioxide, it can not be neglected at all. A Methane molecule can live in the atmosphere for 12 years. Which is very less as compared to the carbon dioxide molecules which live for centuries. But in that less span of time, a methane molecule heats up the environment about 30 times more than carbon dioxide does. And the current situation of pandemic has reported a decrease in the rising level of Carbon dioxide; we notice no such change in case of methane emissions.
“Here we are. It’s 2020, and it’s not only not dropping. It’s not level. In fact, it’s one of the fastest growth rates we’ve seen in the last 20 years,” Drew Shindell, a climate scientist at Duke University.
