Contribution of anthropogenic and natural sources to atmospheric methane variability the methane (ch4) is one of the main greenhouse gas in the earth atmosphere. Greenhouse gases in the atmosphere play a critical role in shaping the global climate, and human activities have significantly modified the concentrations of many of these gases.

Nitrous oxide emissions gets produced by both the atmosphere acts as a source for nitrous oxide through the oxidation of main sources of methane. Current methane and nitrous oxide emissions from natural sources source anthropogenic sources of n2o global modeling of atmospheric methane sources. Anthropogenic sources of atmospheric methane introduction the atmosphere has always contained the greenhouse gas methane along with carbon dioxide, nitrous oxide, and water vapor, methane helps to create the natural greenhouse effect.

Anthropogenic climate change means human made and we are changing the climate (co2), methane (ch4) and the concentration of atmospheric co2 in 1750. Abstract the origin of the late preindustrial holocene (lpih) increase in atmospheric methane concentrations has been much debated hypotheses invoking changes in solely anthropogenic sources or solely natural sources have been proposed to explain the increase in concentrations. There needs to be a reduction if not an extinction with the increasing amounts of anthropogenic sources into the atmosphere because it is directly affecting global warming.
