Climate change, resulting from 'anthropogenic' emissions of GHGs (suit of gases) due to fossil fuel use, certain agricultural & Industrial activities and deforestation leading to their increasing concentrations in the atmosphere, has the potential over the next a few generations to significantly alter Global climate.
'Anthropogenic' means caused or influenced by 'Humans' or 'Human Activity'.
CHG is gas in an atomsphere that absorbs & emits radiation within the thermal Infrared range. This process is the fundamental cause of GH effect.
Climate potential over the next few generations to significantly alter global climate. This would result in large changes in ecosystem, leading to possibly catastrophic disruptions of livelihood, economic activity, living conditions & human health. On the other hand abatement of GHG's would involve significant economic costs.
The primary GHGs in Earth's atmosphere are water vapour, CO2, Methane, Nitrous oxide and Ozone. Anthropogenic or human activities since the beginning of the Industrial revolution ( taken as the year 1750 ) have produced a 40% increase in the atmospheric concentration of CO2 from 280 ppm in 1750 to 400 ppm in 2015. This increase has occurred despite the uptake of a large portion of the emission by various natural 'sinks' involved in the carbon cycle.
Anthropogenic CO2 emissions come from combustion of carbon-based fuels, principally coal, oil & NG along with deforestation, soil erosion & animal agriculture.
It has been estimated that if GHGs emissions continue at present rate, Earth's surface temperature could exceed historical values as early as 2047, with potentially harmful effects on ecosystems, biodiversity & the livelihoods of people worldwide. Recent estimates suggest that on the current emissions trajectory the earth could pass a threshold of 2°C global warming which is the 'upper limit' to avoid 'dangerous' global warming by 2036.
While Climate Change is a global environmental issue, different countries bear different levels of responsibility of increase in atmospheric GHG's concentrations.
Further adverse impacts of climate change will fall disproportionately on those who have the least responsibility for causing the problem, in perticular, developing countries, including India.
Since GHG's emissions are directly linked to economic activity. India's economic growth will necessarily involve increase in GHG's emissions from the current extremely low levels.
Any constraints on the emissions of GHG's by India, whether direct or by way of emissions targets or indirect will reduce growth rates.
