Health Impacts of Climate Change
Save
Climate change is a major threat to human health. The World Health Organization (WHO) has identified climate change as the greatest threat to global health in the 21st century. Climate change is already having a wide range of negative impacts on human health, including:
Extreme Weather Events
Climate change is increasing the frequency and intensity of extreme weather events, such as heat waves, floods, droughts, and storms. These events can cause direct injuries and deaths, as well as damage to infrastructure and property.
For example, the heat wave that hit Europe in 2003 killed over 70,000 people. The floods that hit Pakistan in 2010 displaced over 20 million people and caused billions of dollars in damage.
Air Pollution
Climate change is also increasing air pollution. Air pollution can cause a variety of health problems, including respiratory problems, heart disease, and cancer. For example, the World Bank estimates that air pollution causes 7 million premature deaths each year.
Water Scarcity
Climate change is also leading to water scarcity. Water scarcity can cause a variety of health problems, including dehydration, malnutrition, and disease. For example, the World Health Organization estimates that 1.1 billion people lack access to safe drinking water.
