Abstract

Since the models designed to predict future climate are not producing optimistic results, climate change and global warming is a subject of growing concern today. An increase of about 2-5 ˚C in average temperature induced the melting of around 1 meter of polar ice in the end of 21th century would be catastrophic. Accumulation of greenhouse gases especially methane gas in the atmosphere gets the most credit in climate change and global warming and there is a strong connection between them. Varieties of anthropogenic sources, mostly agricultural and industrial contribute to methane discharge. Half of methane emitted by human is related to the agricultural sector. Domesticated ruminants and rice fields have a high potential for methane production due to the anaerobic processes. Methane which is emitted this way is dependent on variety parameters, which if controlled can lead to a significant reduction in the level of methane emission.
