It is as a result of this vulnerability that forced climate migration could occur. As predicted by the World Bank in 2018, 143 million people may be internally displaced by 2050, due to rising sea levels, reduced crop yield and water insecurity alone. Not accounting for sudden and unpredictable climate events, this already staggeringly high prediction only includes migration as a result of climate processes - slow onset changes to the climate and wider environment. In addition to problems such as rising sea levels, salinisation of agricultural land and desertification, many populations will also face unprecedented devastation from sudden and unpredictable disasters like monsoon floods, storms and bushfires.
Understanding how these two climate drivers will uniquely impact global populations is crucial in how we perceive the future impacts of climate change and consequent migration. The IPCC describes the disproportionate risk of increasing temperatures to be of biggest concern for populations including “disadvantaged and vulnerable populations, some indigenous peoples, and local communities dependent on agricultural or coastal livelihoods.” In populations whereby water, food and infrastructure is already unstable, the repercussions of drought, salinisation and dwindling food stocks can only exacerbate situations.
