From many decades, carbon dioxide (CO2) is considered as the leading cause of global warming, but methane is more powerful than CO2 in catching the heat in the atmosphere of the Earth.
Methane is naturally formed during the digestion process in animals and during decomposition of organic squanders in wetlands and swampy areas.
Scientists have revealed a new study which claims that cow farts can affect global warming and their effect could be much larger than we assumed. And the study published in the journal Carbon Balance and Management and it suggests that calculations of methane emissions from livestock may have been off by 11 percent.
Methane is a natural byproduct of the cow’s digestion and has a big relationship with “greenhouse effect,” in which the atmosphere traps the sun’s heat and warms our planet. While carbon dioxide has a big role in this effect, methane is more effective than CO2 when it comes to trapping heat.
NASA’s Carbon Monitoring System research initiative and the US National Aeronautics provided the sponsorship to this project. Joint Global Change Research Institute’s (JGCRI) researchers discovered that 2011’s global livestock methane emissions are 11% higher than the calculations based on recommendations provided by the Intergovernmental Panel on Climate Change in 2006.
“In many regions of the world, livestock numbers are changing, and breeding has resulted in larger animals with higher intakes of food,” said Julie Wolf, lead author of the study. These livestock management’s changes can increase emissions of methane. Methane is one of the main moderators of the Earth’s atmospheric temperature.
