radiation leads to more heating of atmosphere and resulting in rise in Earth’s
temperature. The GHE has been widely used to describe the trapping of excess heat
due to the rising concentration of carbon dioxide in Earth surface. The carbon
dioxide strongly absorbs infrared and does not radiate it back into the space.
A major part of the efficiency of the heating of an actual greenhouse is the trapping
of the air so that the energy is not lost by convection. Keeping the hot air from
escaping out the top part of the practical “greenhouse effect”, but it is common
usage to refer to the infrared trapping as the greenhouse effect in the atmospheric
applications where the air trapping is not applicable.
Noteworthy greenhouse gases are methane, nitrous oxide, carbon dioxide,
hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride
(SF 6 ). These gases are thought to affect the climate directly and indirectly, even
though they constitute only a small fraction of the blanket of gases that make up the
atmosphere. The greenhouse effect (20.00 %) is attributed directly to carbon dioxide
and 5 % to all other greenhouse gases according to 2010 models cited by NASA.
The remaining 75 % of the greenhouse effect is thought to be due to water vapour
and clouds, which are naturally occurring. However, even though carbon dioxide
and the other greenhouse gases are such a small percentage of the total gas in the
atmosphere, they affect when, where and how clouds form, so greenhouse gases
have some relevance when it comes to 100 % of the greenhouse effect. Carbon
dioxide is thought to modulate the overall climate, like an atmospheric thermostat.
4.1 Ruminants and Global Warming
Ruminants are the herbivores that consume plants and digest them through the
process of enteric fermentation in their four chambered stomach. Ruminants include
cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. Unlike to the monogastric species (human, dog, cat, etc.), ruminant stomach is having four chambers.
