Abstract
Rising CO2 levels in the atmosphere, a major contributor to climate change, has a wide range of consequences. CO2 can absorb and radiate heat energy resulting in the hike of earth’s average temperature. The elevated CO2-induced temperature rise in the atmosphere has a severe impact on agricultural crop productivity, as temperature is one of the important abiotic factors which influence crop growth and development. So the high temperatures and drought that accompany climate change will decrease food production and threaten food security globally.
