Climate change poses increasing risks to public health security. Populations in developing countries, particularly tiny island nations, dry and high mountain zones, and heavily populated coastal areas are thought to be more vulnerable. One billion people in rural regions rely on climate-sensitive sectors (agribusiness, forestry, and fisheries) and natural resources (such as water, biodiversity, mangroves, coastal zones, and grasslands) for subsistence and livelihood. Heatwaves, floods (both land and coastal), and severe droughts are all regular occurrences.
The Effects of Climate Change
- Outdoor work may become intolerable.
- Increased electricity costs and more outages
- More allergies, as well as other health risks
- Food will become more costly, and diversity may suffer as a result.
- Water quality may suffer.
The Effects of Climate Change on Human Health and Health Care
All human populations rely on food and water sources, as well as the physical protection and comfort provided by climatic stability. The global climate system is critical to life support. A changing climate is anticipated to alter all of these circumstances, having a significant impact on human health and well-being. Extreme weather events have resulted in the spread of vector-borne illnesses such as malaria and dengue.
Climate change poses a threat to the healthcare system and access to healthcare services including rising temperatures and shocks such as extreme weather conditions and disruptions caused by water scarcity. Water is required for the safe delivery of medical care. i.e. Hand washing, disinfecting wards, surgical instruments, cleaning equipment, and laundry all require it.
Other consequences include Forest fires, poor air quality, and changes in disease vectors among the other repercussions. The impact on critical infrastructures, such as power and roads, can stymie health care delivery and patient care.
The following are direct impacts of man-made climate change:
- Increasing maximum temperatures
- Minimum temperatures are increasing.
- Increasing sea levels, greater ocean temperatures
- An increase in heavy rains
- A rise in the frequency of violent tropical cyclones
- The rise in aridity and thirst reduction in the sea ice and snow cover glacier shrinkage and retreat melting permafrost
Climate change disrupts the Earth’s temperature balance and has far-reaching implications for humans and the ecosystem. There is a contrast between the immediate and indirect consequences of climate change. Because of the rising atmospheric concentrations of greenhouse gases, the energy balance and consequently the temperature of the Earth fluctuate throughout global warming, which has a profound influence on humans and the environment.
