Not Available. Climate change and air pollution are linked to one another by our increasing use of fossil fuels, including coal, petroleum, and natural gas. One such pollutant is ground-level ozone, the major component of smog. Ozone is formed from the reaction of nitrogen oxides and volatile organic compounds, as from power plant emissions and automobile exhaust, in the presence of light and heat.

Approximately 7 million premature deaths annually are due to the effects of air pollution, about 4 million of which are due to ambient outdoor air pollution. Beyond shortening lives, air pollution can negatively impact our day-to-day lives, causing respiratory illness and leading to days of missed work and school. Children are especially vulnerable to the impacts of air pollution : exposure to air pollution in early childhood, when the lungs are still developing, can lead to reduced lung capacity that persists through adulthood. Black carbon BC, also known as soot is a component of fine particulate matter PM2. Particulate matter is the air pollutant that is most harmful to human health and the primary driver of air pollutant-induced mortality. Methane CH4 does not have any direct human health effects in the sense that inhaling typical ambient concentrations of methane is not harmful to human health. However, methane has a very important indirect human health impact, because it is a precursor to ground-level ozone O3, also known as tropospheric ozone , which causes asthma and other respiratory diseases and contributes to air pollution-related premature deaths.

Research has also evaluated actions that could be taken—and in some cases are already being taken—to limit the magnitude of future climate change and adapt to its impacts. In the United States, a series of reports by the U. Internationally, scientific information about climate change is periodically assessed by the Intergovernmental Panel on Climate Change IPCC , most recently in

Climate change and air pollution

The observational evidence indicates that recent regional changes in climate, particularly temperature increases, have already affected a diverse set of physical and biological systems in many parts of the world. Allergens patterns are also changing in response to climate change and air pollution can modify the allergenic potential of pollen grains especially in the presence of specific weather conditions. Although genetic factors are important in the development of asthma and allergic diseases, their rising trend can be explained only by changes occurring in the environment and urban air pollution by motor vehicles has been indicated as one of the major risk factors responsible for this increase. Despite some differences in the air pollution profile and decreasing trends of some key air pollutants, air quality is an important concern for public health in the cities throughout the world. Due to climate change, air pollution patterns are changing in several urbanized areas of the world with a significant effect on respiratory health. The underlying mechanisms of all these interactions are not well known yet.

We are living in the Anthropocene. Human beings have become a major force by massively polluting the air we breathe as well as the entire atmosphere, which maintains the climate in a habitable zone. Close to one trillion tons of air and climate pollutants are blanketing the earth, and trillions of additional tons will be added this century. Millions of people are dying prematurely every year due to air pollution. If climate pollutant emissions are allowed to continue well into the twenty-first century, global warming and climate change can pose existential threats to Homo sapiens and many other species.

Climate change includes both global warming driven by human emissions of greenhouse gases , and the resulting large-scale shifts in weather patterns.

Climate Change, Air Pollution, and Health: Common Sources, Similar Impacts, and Common Solutions

Войдя, Дэвид увидел мигающую лампочку автоответчика. Слушая сообщение, он выпил почти целый пакет апельсинового сока. Послание ничем не отличалось от многих других, которые он получал: правительственное учреждение просит его поработать переводчиком в течение нескольких часов сегодня утром. Странным показалось только одно: об этой организации Беккер никогда прежде не слышал. Беккер позвонил одному из своих коллег: - Тебе что-нибудь известно об Агентстве национальной безопасности. Это был не первый его звонок, но ответ оставался неизменным: - Ты имеешь в виду Совет национальной безопасности.

Какая разница? - подумал.  - Я должен выполнять свои обязанности. Он поднял телефонную трубку и набрал номер круглосуточно включенного мобильника Джаббы. ГЛАВА 45 Дэвид Беккер бесцельно брел по авенида дель Сид, тщетно пытаясь собраться с мыслями. На брусчатке под ногами мелькали смутные тени, водка еще не выветрилась из головы. Все происходящее напомнило ему нечеткую фотографию. Мысли его то и дело возвращались к Сьюзан: он надеялся, что она уже прослушала его голос на автоответчике.

Фонтейн был гигантом из гигантов, но Стратмора это как будто не касалось. Он отстаивал перед директором свои идеи со спокойствием невозмутимого боксера-профессионала. Даже президент Соединенных Штатов не решался бросать вызов Фонтейну, что не раз позволял себе Стратмор.

Бринкерхофф поднялся со своего места, словно стоя ему было легче защищаться, но Мидж уже выходила из его кабинета. - Руки на стол, - бросила она через плечо.  - Когда я уйду, пожалуйста, никаких глупостей. И у стен есть .
