Methane emissions on the increase

There is an increased amount of methane produced in the earth’s atmosphere, as indicated by a research carried out by the Carbon Global Project. Researchers combined all information concerning methane from emissions inventories, pressure figures, and other structures to come up with a ‘methane budget.’ The model constitutes methods that add methane gas to the air and the ways of removing it. The researchers later found out that large-scale emission of the compelling greenhouse amassed to 576 million metric tons every year in the 2008-2017 decade. That equates to a 9 percent increase when compared to the last ten years (1998-2007).

The increased growth accumulated due to the growth in the atmospheric absorption of methane in the last ten years with climate researchers estimating that methane is among the causes of global warming (which has taken place twice) that are approximately one quarter. 

Human activities, such as fossil fuel and agricultural activities, are among the crucial factors that have primarily increased global warming. The main activities associated with the surge in global warming include; mining of coal, rearing of livestock, disposal of wastes in landfills, and manufacturing of gas and oil.

According to research carried out over the previous years, 30 percent of the global methane emissions are as a result of wetlands, and gas, oil, and coal activities contribute to 20 percent. Agricultural activities such as enteric fermentation and management of manure contribute to 24 percent of emissions, landfills making up 11 percent of emissions. South America, Africa, Asia, and other temperate regions contribute to 32 percent of the emissions, while the Arctic accounts for 4 percent. 

Ecosystems in the high-altitude regions are more susceptible to climatic changes: frozen soils (permafrost) as well as forest vegetation in Arctic store vast amounts of carbon. Water-logged soil has also become sensitive to methane production. Despite thawing permafrost and rising records of air temperature, research will still be carried out to find out the atypical emissions of methane in latitude areas. 

Arctic-Boreal Vulnerability Experiment (ABoVE) of NASA is among the many organizations that have helped in the full understanding of climatic changes and how the changes affect methane emissions. Not so long, ABoVE researchers found hyperspectral airborne observations, which asserted that there is a presence of million sources of methane gas in little ponds and lakes located in some regions of Alaska and Western Canada.
