Global warming, as one of the many facets of climate change is unequivocally the most pivotal climate, health, security and economic issue of the 21st century. The anthropogenic factors towards global warming are inextricable to the exponential increase in global mean temperature and its reciprocal effect on global climate systems (IPCC 2014; Keller et al. 2005; Rogelj et al. 2015a). Explicitly, international initiatives to maintain below a increase of 1.5˚C and far less than 2˚C above pre-industrial GMT levels needs to be implemented at government and industry levels of the energy-supply, private and within building/transport sectors. The plausible implementation of mitigation initiatives are explicit within contemporary society at local levels of agriculture (Fischer et al. 2002) and of a global scale with bioengineering and geoengineering (Creutzig et al. 2015; Crutzen 2006).

Origination

The GMT threshold of 1.5˚C above pre-industrial levels originated from modest initiatives from the 2˚C limit presented in 1975 by economist William NordHaus (Nordhaus 1975) after which was affirmed as a maximum point of GMT increase by the stockhold environment institute in 1990 (Rijsberman and Swart 1990). Correspondingly after, NASA scientist James Hansen, testified to congress of the inseparable correlation between greenhouse emissions to rising temperatures and the reciprocal impacts associated with such emissions. These initiatives instigated an increase in extensive…
