One of the climate change model predictions is that there will be more extreme weather and climate events and their intensity will be stronger. For example, many studies have linked an increase in wildfire activity to global warming. 2. 2011-2012: East Africa drought. Scientific studies indicate that extreme weather events such as heat waves and large storms are likely to become more frequent or more intense with human-induced climate change. Population exposure to heat is increasing due to climate change, and this trend will continue. Studies conducted by the Centers for Disease Control and Prevention (CDC) have shown that exposure to extreme heat can increase discomfort and fatigue, cause heat cramps, and increase emergency room visits and … Extreme Weather and Climate Change One of the most visible consequences of a warming … Copyright © 2020 Elsevier B.V. or its licensors or contributors.
