Climate Change: Its Ill-Effects on Health
The rise in temperature of the atmosphere is more specifically called global warming. However, the term "climate change" is the current term favored by scientists since it specifically includes not just the rising global average temperature as well as the effects on climate caused by the increase. All gasses that have the capability of absorbing infrared radiation that is emitted by the Earth's surface and radiating it back towards Earth's surface, is referred to as greenhouse gas. Methane, carbon dioxide, as well as water vapour are among the most significant greenhouse gases. Others greenhouse gasses include but aren't restricted to, surface-level ozone and nitrous oxide, sulfur hydrofluorocarbons, hexafluoride per fluorocarbons, and chlorofluorocarbons. Although it is a natural phenomenon it causes a warming of the troposphere and surface of Earth - the smallest layer of the atmosphere. Of all greenhouse gases, water vapor is the most significant impact. The main causes for greenhouse effects include the burning of fossil fuels like coal, oil , and natural gas, forest destruction and population growth, agriculture, industrial wastes and landfills. Greenhouse gases absorb heat from the atmosphere. When they are present in higher concentrations than normal they cause an unnaturally warm climate. The primary cause for the current trend of global warming is the human-induced expansion of the greenhouse effect, which is a warming that occurs from the trapping of the heat that is radiating from Earth towards space. A small temperature rise could have worrying consequences such as rising sea levels, displacement of populations and disruptions to food supply, flooding and adverse health effects. In reality humans' health is the most burden of effects of climate change. The negative effects of climate change on health - The effects of climate change on human health mainly in two ways: one it can alter the intensity or frequency of health issues that are already impacted by climate change and secondly, by causing health issues in areas that they've never been present. The effects of temperature increases The effects of temperature increase The rising concentrations of greenhouse gases result in an increase of extreme and average temperatures. This could affect the body's ability to regulate temperature. The loss of internal temperature control could result in a rash of ailments, such as heat cramps, heat exhaustion hyperthermia and heatstroke in the conditions of intense heat, as well as frostbite and hypothermia in conditions of severe cold. Extreme temperatures can also exacerbate chronic illnesses like respiratory diseases, cardiovascular disease, cerebrovascular disease and diabetes-related ailments. Socially marginalized, economically poor and those suffering from chronic illness are more susceptible to the effects of temperature rise. For more detail please visit:- The effects of air quality The effects of air quality Climate change has altered the weather pattern, and in turn has influenced the amount and locations of air pollutants in the outdoors such as ground-level Ozone (O3) as well as fine particles. The rising CO2 (CO2) levels also encourage the development of plants which emit airborne allergens. More pollen and longer seasons of pollen can lead to asthma and allergic sensitization which can reduce productivity at school and at work. Insufficient air-quality, whether indoors or outdoors, may adversely affect cardiovascular and respiratory systems of the human body. The effects of extreme events -- Climate change can lead to the frequency and intensity of certain extreme events. These could have adverse health effects like injury or death during the event, for instance, drowning in floods. The health effects can also happen prior to and following an event that is extreme, since those involved in tasks such as disaster planning and cleaning up after the event risk their health. The extent and severity of health-related effects that are that are associated with extreme events are dependent on the physical effects of the events themselves. Vector borne diseases - The transmission of vector-borne diseases is through vectors that include ticks, mosquitoes, and fleas. They can transmit infectious pathogens like viruses, protozoa and bacteria, that can spread between hosts (carrier) in one host to the next. The distribution, seasonality and frequency of vector-borne illnesses are affected greatly by the climate. Climate change will be a factor in both short- and long-term impacts on the transmission of vector-borne diseases and the patterns of infection, which will affect the risk of disease and its seasonal incidence over time. Water-related diseases - Climate change is predicted to impact fresh and marine sources of water in ways which could increase the risk of exposure to water-related pollutants that can result in illnesses. Waterborne illnesses are caused by pathogens like bacteria protozoa, viruses, and fungi. These illnesses can also be caused by the toxins created by harmful algae, and by the introduction of chemicals into water bodies by humans' activities. The exposure is caused by ingestion or direct contact with the water that is contaminated for drinking or recreation as well as through the consumption of contaminated seafood and fish. Mental health effects The effects on mental health The mental health effects of climate change can range from a few minor stress and anxiety symptoms to more serious disorders like depression, anxiety and post-traumatic stress. They can also trigger suicidal tendencies. Children, the elderly women (especially post-partum and pregnant women) and those with a an existing mental illness, those who are poor and homeless are the most vulnerable to the mental health effects of climate change. Food quality and safety - Climate change is likely to impact the global, regional and even local food security by affecting food availability and reducing access to food , and making it more difficult to use. The higher concentrations of CO2 could reduce the amount of protein and other essential minerals in a variety of commonly consumed crops, such as rice, wheat and potatoes, which could have potential negative consequences for the human diet. A poor nutritional quality of food can affect negatively the most vulnerable segments of the population. It's the bottom line - In the past 50 years Human activities have produced enough carbon dioxide as well as other greenhouse gases that trap more heat in the lower atmosphere , affecting our global climate. As per WHO (World Health Organisation):
  • Changes in the climate affect the environmental and social determinants of health, such as clean air and safe drinking water, adequate food supply and safe shelter.
  • Between 2030 to 2050, climate change is predicted to result in approximately 250000 deaths more per year due to malnutrition, diarrhea, malaria as well as heat-stress.
In light of the severe effects of climate change for our health, we all must work together to cut greenhouse gases by making better transportation, food and energy options to improve our health , particularly by reducing air pollution. Climate change is now an issue that is global in nature because it has a myriad of negative effects which include those that affect the human health.Climate change must be addressed by each nation and also the people who live in those countries.
