Over the years, studies have shown that several factors significantly contributed to this worsening 'event' in human history, citing land use change, sulfate aerosols and black carbon, and greenhouse gases as main culprits. However, with recent political events that aimed to provide concerted efforts to alleviate the effects of global warming, the United Nations-formed group International Panel on Climate Change, or IPCC, has established that scientifically, that the "gas responsible for the most global warming is carbon dioxide, also called CO2" (National Geographic, 2011: para 3).
