What is meant by increasing global heat?
Largely anthropogenic activities including various types of pollution, industrialization, and overpopulation are the main drivers of the change factor on the globe. The main cause of rising temperatures is the greenhouse effect that raises Earth’s temperatures.
Several greenhouse gases including water vapors, carbon dioxide, and CFCs trap solar radiation and don’t let them go back to the atmosphere. The more is the amount of these gases the more is the trapped heat. This causes an increase in the Earth’s temperature.
The warmer temperatures are turning the weather to get more extreme triggering the heavy storms, flash floods, snowfalls and, prolonged severe drought-like conditions.
Climatic changes can directly affect people’s health
The combination of smoke and fog that happens more rapidly in urban areas produces smog. The higher levels of smog in the atmosphere pose serious health problems including asthma, heart disease, and lung cancer.
Climatic changes and their resultant floods and runoff waters contaminate the drinking water facility and increase the exposure to waterborne pathogens. This factor will also contaminate the water bodies as the flood water returns to water reservoirs.
Widespread disposal of plastic wastes into the seas and oceans damages the aquatic habitats and also badly affects the human population when they feed on these sea animals including fishes.
The International Journal of Science – Nature reveals that many prevalent human diseases are linked to climate fluctuations, from cardiovascular mortality and respiratory illnesses due to heatwaves to transmission of infections and malnutrition resulting from crop failures.
Climate factor is a risk to mental health
The United States Environmental Protection Agency reveals that any changes in a person’s physical health or surrounding environment can have serious implications on mental health.
A person with mental illness is especially vulnerable to extreme heat as pre-existing mental illness triples the risk of death during heat waves. Also, the threat of climate change can influence stress responses among individuals.
