Why the Emergency Management Community Should be Concerned about Climate Change

Increases in the concentrations of atmospheric greenhouse gases from activities such as burning fossil fuels and deforestation have caused a measurable increase in global temperatures. As greenhouse gas concentrations continue to increase, further changes in the Earth’s climate are expected. These changes may impact the location, frequency, and occurrence of natural hazards such as tropical cyclones, wildfires, floods, and winter storms. Thus, the historical data that are typically the basis of hazard identification and risk assessment may not accurately forecast future events. Consequently, we need to begin to evaluate and better understand how climate change could affect the identification and selection of disaster mitigation strategies, the types of preparedness activities that jurisdictions undertake, the execution of response operations, and the implementation of long-term recovery strategies
