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.
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.
This reaction occurs more rapidly at higher temperatures, explaining, in part, why smog is more marked during the summer months. Global warming would be expected to worsen this form of air pollution. Ozone has been linked to decreased pulmonary function in healthy adults, an effect that depends on exposure concentration and duration. High-level exposure 5. More generally, elevated ozone levels have been found to lead to more frequent asthma attacks, emergency department visits, and hospitalizations; increased use of asthma medications; and greater morbidity and mortality in patients with pre-existing pulmonary or cardiovascular disease.
The burning of fossil fuels produces other major air pollutants including airborne particulates, nitrogen oxides, and sulfur oxides. Oxides of nitrogen NO X are formed during high-temperature combustion processes, such as those that power automobiles and power plants.
Oxides of sulfur SO X are formed when fuel containing sulfur mainly coal and oil is burned, as during metal smelting and other industrial processes. One study of never-smoking cohorts grouped by age years old compared areas in southern California with moderate levels of SO 2 , NO 2 and particulate matter mean values: 0. A larger, more recent study concluded that fine particulate and sulfur oxide—related pollution is associated with all-cause, lung cancer, and cardiopulmonary mortality, after controlling for cigarette smoking, occupational exposure, and other risk factors.

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 Much has been learned, and this knowledge base is continuously being updated and expanded with new research results. Our assessment of the current state of knowledge about global climate change, which is summarized in this chapter and described in detail in Part II of the report, leads to the following conclusion.
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.

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.

Climate change includes both global warming driven by human emissions of greenhouse gases , and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change , since the midth century humans have had unprecedented impact on Earth's climate system and caused change on a global scale. Temperature rise on land is about twice the global average increase, leading to desert expansion and more common heat waves and wildfires.
Как только освобожусь, загляну в шифровалку и… - А что с аварийным питанием. Если закоротило генератор, почему оно не включилось. - Не знаю. Может быть, Стратмор прогоняет что-то в ТРАНСТЕКСТЕ и на это ушло все аварийное питание. - Так почему он не отключит эту свою игрушку.
- Стратмор приподнял брови. - В них постоянно упоминается Цифровая крепость и его планы шантажа АНБ. Сьюзан отнеслась к словам Стратмора скептически. Ее удивило, что он так легко клюнул на эту приманку.
