The temperature increase in the atmosphere is more specifically referred to as global warming. But the climate change is the name currently used by scientists, as it explicitly includes not only the rising global average temperature but also the climate-related effects resulting from this rise. Any gas, which has the property of absorbing infrared radiation that is emitted by Earth's surface and reradiating it back towards Earth's surface, is called greenhouse gas. The greenhouse gases are methane and carbon dioxide along with water vapour, are among the most important greenhouse gases. Other greenhouse gases include, but are not restricted to, surface-level ozone and nitrous oxide, sulfur hexafluoride, hydro fluorocarbons, per fluorocarbons and chlorofluorocarbons.

Of the greenhouse gases, water vapor has the largest effect. One of the major causes of the greenhouse effect are the burning of fossil fuels like coal natural gas, oil, and coal the deforestation process, the increase in population, agricultural practices and industrial wastes, as well as landfills. Greenhouse gases hold heat in the atmosphere. When they are present in higher concentrations than normal they can cause unusually hot temperatures. The main cause of the current global warming trend is the human-induced expansion of the greenhouse effect, a temperature rise that happens when the atmosphere traps heat radiating from Earth toward space. Even a modest global temperature increase could lead to troubling consequences like rising ocean levels, population displacement disrupting the water supply, and ill-effects on health. As a matter of fact humans' health is the brunt of the consequences of the climate change. The negative effects of climate change on health The effects of climate change on human health mainly in two ways: first, by changing the severity or frequency of health issues that are already affected by climate changes and secondly, by causing health issues in areas where they have not previously occured. The effect of temperature rise (- Increased concentrations of greenhouse gas cause an increase in both average and extreme temperatures. This could affect the body's ability in regulating its temperature. In the absence of internal temperature regulation, it could result in a rash of ailments, such as heat cramps, exhaustion of heat, hyperthermia and heatstroke, in the presence of extreme heat, and hypothermia and frostbite in circumstances of cold extremes. Extreme temperatures can also exacerbate chronic conditions like cardiovascular disease, respiratory diseases, cerebro-vascular disease and diabetes-related diseases. Outdoor workers, those who are socially lonely, economically marginalized and those suffering from chronic illness are more susceptible to the effects of temperature rise. Impacts of air quality The effects of air quality Climate change has modified patterns of weather and, in turn, have an impact on the concentration and distribution of outdoor air pollutants including ground-level ozone (O3) as well as fine particles. The rising the carbon dioxide (CO2) levels also aid in the growth of plants which release airborne allergens. A higher level of pollen and longer periods of pollen season can cause allergic sensitization and asthma episodes, thereby limiting productivity at the workplace or at school. Air quality issues, outdoors or indoors, can adversely affect cardiovascular and respiratory systems of the human body. The effects of extreme events - Climate change causes an increase in the occurrence and severity of some extreme events, which could result in health issues like death or injury in the course of an event, for example, drowning during floods. The health effects can also happen during and after an extreme event, because individuals involved in activities such as preparation for disasters and post-event cleanup can put their health in danger. The intensity and the extent of health risks associated with extreme events depend on the physical consequences of the events themselves. Vector borne diseases - The transmission of vector-borne diseases is through vectors, which include ticks, mosquitoes, as well as fleas. These vectors can carry infective pathogens like viruses, protozoa, and bacteria which can be transferred between hosts (carrier) into another. The frequency, seasonality and incidence of diseases transmitted by vectors are affected greatly by the climate. Climate change could cause both short as well as long-term consequences on the transmission of vector-borne diseases and infection patterns, affecting the risk of developing seasonal illness as well as spread over a long period of time. Water related diseases Climate change is expected to affect both marine and fresh waters in ways that will increase people's exposure to water-related pollutants that cause diseases. Waterborne illnesses are caused by pathogens like bacteria protozoa, viruses, and fungi. Water-related illnesses are also caused by the toxins created by harmful algae and by chemicals introduced into water sources by human activities. Ingestion of the toxins can cause exposure of contaminated drinking or recreational water and through consumption of contaminated marine food and fish. Impacts on mental health -- The mental health effects of climate change vary from minimal stress and distress symptoms to severe disorders such as depression, anxiety, post-traumatic stress, and suicidal tendencies. Children, the elderly women (especially pregnant women and post-partum women) and those with a an existing mental illness, those who are those who are economically marginalized and those who are homeless are more vulnerable to the mental health effects of climate change. Effects on food quality and safety Climate change is extremely likely to affect local, regional and local food safety in the form of disrupting food supply and reducing access to food and making the process more difficult. Higher concentrations of CO2 can decrease the levels of protein and essential minerals found in several commonly consumed crops such as wheat, rice, and potatoes, with potentially negative implications for the human diet. A poor nutritional quality of food is more likely to impact the weaker sections of the population. "The bottom line - In the past half century, humans' activity has released sufficient quantities of carbon dioxide and other greenhouse gases, which trap additional heat in the atmosphere , affecting the global climate. As per WHO (World World Health Organization):
- The effects of climate change are on the environmental and social factors of health, such as clean air and safe drinking water, sufficient food and secure shelter.
- Between 2030 and 2050, climate change is predicted to result in approximately 250000 additional deaths per year, from malnutrition, diarrhea, malaria and heat stress.
