In the pursuit of decreasing the level of carbon dioxide consumption, we are often overlooking the appalling effects of other greenhouse gas emissions. Though CO2 has been recognized as the most contributing anthropogenic greenhouse gas, the emission of methane has also significantly increased to a great extent and is gradually becoming a crucial area of concern.
Methane is a danger in disguise, as they more amount of heat compared to carbon dioxide (which is observed to be around 30 times more). However, since the proportion of its atmospheric concentration is comparatively lesser than carbon dioxide, its aggregated effect is also being observed to be less. But, scientists have started making more emphasis on the way it is released into the atmosphere. Carbon dioxide is primarily emitted due to burning of fossil fuels, however, the maximum proportion of methane emission is stemmed by a natural component. The warming of permafrost present in the northern latitudes is the most severe cause of methane emissions and one of the appalling effects of global warming. Permafrost is a perennially frozen land which, is mostly unruffled by bacterial decomposition.
With the average temperature rising up all across the globe, the permafrost has started melting down with which, the amount of soil decomposition is also accelerating fast. Resultantly, an initial warming is igniting the fuel for more emissions, thereby leading to increased emissions and increased warming as well. The phenomenon are gaining the shape of a wicked cycle, thereby emerging as the tipping point of CH4 emissions.
Reports have stated that a total amount of 205 gigatons of carbon dioxide is expected to get released because of the melting of permafrost. This, in turn, would cause a steep rise of up to 0.5 degree Celsius (0.99 degree Fahrenheit). Furthermore, the permafrost melting is expected to continue even after 2100, thereby making the situation worse for sustenance of life in our Mother Earth.
Permafrost contains twice the amount of carbon present in the atmosphere. As the temperature in the Arctics continues to rise drastically, the topmost layers of the frozen land continue to defrost, which in turn, drive the deposited organic materials to decay and break down. Plant materials which, have been accumulated deep inside for more than thousands of years are concentrated now in the upper layers.
Coping up with the dreadful effects of global warming is unduly intimidating and the situation gets really worse when we do not have a well-sorted out programme to prevent the same. Thousands of initiatives have been launched and implications have been set and thousands more are yet to be implemented by now. But, combating the natural contributors to global warming happens to be one of the most gargantuan tasks which, we need to accomplish tactfully for preserving our future.
