Consumption of fossil fuels has increased to satisfy the growing demand for rising industrial activities, expanding transportation, intensifying agriculture and burgeoning population since the 1850s. Burning fossil fuels has led to a significant rise in the emission of gases, such as CO2, CH4, NOx, etc. (collectively known as greenhouse gases, GHGs) in the atmosphere. Consequently, more reflected radiation or heat is trapped in Earth’s atmosphere, raising its temper-ature and causing climate changes. The recently released Sixth Assessment Report (AR6) by Intergovernmental Panel on Climate Change (IPCC) mentions that ‘it is unequivocal that human influence has warmed the atmosphere, ocean and land’. IPCC also notes that ‘the likely range of total human-caused global surface temperature increase from 1850–1900 to 2010–2019 is 0.8°C to 1.3°C, with the best estimate of 1.07°C’ © 2022.
