e. Air pollution is the contamination of air due to the presence of substances called pollutants in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. [ 1] It is also the contamination of the indoor or outdoor environment either by chemical, physical, or biological ...
Air pollution can affect nearly every organ and system of the body, negatively affecting nature and humans alike. Air pollution is a particularly big problem in emerging and developing countries, where global environmental standards often cannot be met. The data in this list refers only to outdoor air quality and not indoor air quality, which ...
Global Alliance on Health and Pollution. GAHP (Global Alliance on Health and Pollution) is a network of international and national level agencies committed to a collaborative, multi-sectoral approach to address the global pollution crisis and the resulting health and economic impacts. GAHP’s overall goal is to reduce death and illness caused ...
[264] [265] Climate change mitigation is interconnected with various health co-benefits, such as those from reduced air pollution. [265] Air pollution generated by fossil fuel combustion is both a major driver of global warming and the cause of a large number of annual deaths. Some estimates are as high as 8.7 million excess deaths during 2018.
exert a considerable impact on global warming, because it is a key air pollutant and greenhouse gas, and; impact the production of surface level ozone (contributing again to climate change). As a result, photochemical smog pollution at the earth's surface, as well as stratospheric ozone depletion, have received a lot of attention in recent years.
Major current environmental issues may include climate change, pollution, environmental degradation, and resource depletion. The conservation movement lobbies for protection of endangered species and protection of any ecologically valuable natural areas, genetically modified foods and global warming. The UN system has adopted international ...
Air pollution measurement is the process of collecting and measuring the components of air pollution, notably gases and particulates. The earliest devices used to measure pollution include rain gauges (in studies of acid rain ), Ringelmann charts for measuring smoke , and simple soot and dust collectors known as deposit gauges .

Global cooling was a conjecture, especially during the 1970s, of imminent cooling of the Earth culminating in a period of extensive glaciation, due to the cooling effects of aerosols or orbital forcing. Some press reports in the 1970s speculated about continued cooling; these did not accurately reflect the scientific literature of the time ...
