Air pollution is intricately linked with conventional energy sources. Greenhouse gas (GHG) emissions are the key linkages between environmental pollution and climate change. GHGs’ accumulation in the atmosphere disproportionate to original atmospheric gaseous composition disturbs the normal temperature range, putting the living organisms under stress. The ability of each GHG to absorb energy and duration of its stay in the atmosphere are responsible for warming the globe. Each GHG has its own global warming potential (GWP) measured against CO2. Global warming and climate changes are further accentuated due to human activities leading to land-use changes, alteration of nitrogen and phosphorus cycles, ocean acidification, atmospheric aerosol loading, biodiversity erosion, overuse of global freshwater sources, chemical changes, and stratospheric ozone depletion. The most striking and clearly visible changes are extreme weather events, a decline in Arctic Sea ice, glacier retreat, and sea level rise. Increasing local heating, prolonged heatwaves, frequent storms, recurrence of drought-flood cycles are also the clear symptoms of the ongoing climate change. Enduring increases in CO2 levels and corresponding increases in temperatures would be perilous for the overall performance of food crops because of consequent erratic weather cycle, increased evaporation rates, increased decomposition rates of organic matter, deterioration of soil health, proliferation of insects, invasion of non-native plants, etc. Animal husbandry is more vulnerable to climate change than crop husbandry. Climate change is inviting many unprecedented diseases that would certainly pose threats to the entire human race. From individuals, the diseases percolate into society. Long-term impacts of climate change are likely to be extremely formidable.
