- Abstract
The frequency of climate-induced disasters (CID) has exhibited a fivefold increase in the last five decades. In terms of CID global impact, around 1.7 billion people were affected in the last decade, and in 2020 alone, 30 million people were displaced due to CID. Furthermore, over the past two decades, 1 million deaths were reported and over $1.7 trillion in damage was attributed to CID. As such, the World Economic Forum, in its 2022 report, has identified climate action failure and extreme weather as the two most severe global risks to be considered over the next decade. Given the uncertainty and complexity associated with predicting CID frequencies and related impacts, the use of descriptive-, predictive- and prescriptive data analytics is key. To demonstrate the power of data analytics in predicting CID impacts, this work focuses on developing a data-driven machine learning model that predicts tornado-induced injuries based on a diverse set of input features ranging from hazard-, social-, geographic-, and climate-related features together with attributes related to community vulnerability, risk and resilience. These input features are then used to train and test various machine learning-based prediction models utilizing diverse techniques including decision trees, ensemble methods, and artificial neural networks. These models are subsequently evaluated to select the most significant features and the best performing model. In addition, several variable importance techniques are used to evaluate the dominance of all features and develop a model considering the most influential features. The results show that the best performing model had a testing accuracy of 83%. In addition, the results highlighted the apparent relationship between hazard-related attributes and tornadoes' injury predictions. The developed approach is a step forward in harnessing the power of machine learning for improving our adaptation, preparedness, and planning towards global CID resilience.
