Global warming has long been condemned without question behind the documented rise in average global temperature on the Earth’s surface; about an increase of 0.6C out of a total 0.8C in the previous three decades alone, as stated in the IPCC Fifth assessment report (2013). The research paper aims to provide valuable information to draw out clear implications of anthropogenic climate change and help identify its ominous connection with the increase in severity and frequency of weather extremes and hazards, whilst also emphasizing the need to acknowledge this growing connection and hence develop fitting adaptation and mitigation strategies.
In the geologic past, atmospheric temperatures have varied several a times from natural factors like changes in the sun’s force, increased volcanic activity, vacillations in Earth’s circle; interestingly not one of these natural causes attribute to the present ascent in worldwide temperatures. An overwhelming number of scientific measurements and studies point to escalating greenhouse gas emissions from human factors like industrialization, fossil fuel burning – trapping excess heat in the Earth’s atmosphere, leading to warmer temperatures, recurrently referred to as global warming – being the predominant factor behind witnessing the Earth’s twelve hottest years since 1998 alone (Rogers, 2018).
In recent periods notably this increased climate change has led to even variable and extreme weather patterns, such as a significant rise in intense climatic hazards worldwide, specifically floods, droughts, heat waves and hurricanes.
2. Literature review
With global warming, the rise in average temperatures combined with increased temperature variability from weather extremes, have steered the planet to witness a spur of damaging weather-related natural hazards like heat waves, heavy downpour and droughts over the past few years. Hegerl, G. C. et al. (2007) and several others hence denote that this increasingly evident yet truly uncertain connection – between climatic change and the distribution, potency and/or perpetuation of natural disasters – has become a significant domain for scientific study, proving a direct relation with future weather trends however. Mann and Emanuel (2006) examines the direct link between twentieth and twenty-first century growing concentrations of greenhouse-gas with the rising severity of snowfall and precipitation in the north and flood risks in the United Kingdom for instance, drawing out results that anthropogenic elements were key to long?term shifts in warming and tropical cyclone activities in the Atlantic, and that at the least anthropogenic warming has two-folded the plausibility of extremities like the European heat waves of 2003. Further studies released by the Intergovernmental Panel on Climate Change (IPCC) in 2013 and Kadave et al. (2016) attribute floods and storm intensity to human-induced climate change. Although undoubtedly humans are altering climatic patterns as observed, the exact magnitude of the attribution necessitates a further rigorous experimentation combining probability theories, weather surveillance and climatic models.
