  2. Air pollution - Wikipedia

    en.wikipedia.org/wiki/Air_pollution

    Air pollution can occur naturally or be caused by human activities. [4] Air pollution causes around 7 or 8 million deaths each year. [5] [6] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer.

    A 2019 study reported that "widescale adoption of radiative cooling could reduce air temperature near the surface, if not the whole atmosphere." [ 5 ] To address global warming, PDRCs must be designed "to ensure that the emission is through the atmospheric transparency window and out to space, rather than just to the atmosphere, which would ...

    en.wikipedia.org/wiki/Climate_change

    Changes in surface air temperature over the past 50 years. [1] The Arctic has warmed the most, and temperatures on land have generally increased more than sea surface temperatures. Earth's average surface air temperature has increased almost 1.5 °C (about 2.5 °F) since the Industrial Revolution. Natural forces cause some variability, but the ...

  8. Vortex tube - Wikipedia

    en.wikipedia.org/wiki/Vortex_tube

    Air is separated causing a cooler air stream coming out the exhaust hoping to chill as a refrigerator. [22] In 1988 R. T. Balmer applied liquid water as the working medium. It was found that when the inlet pressure is high, for instance 20-50 bar, the heat energy separation process exists in incompressible (liquids) vortex flow as well.

  9. Thermal pollution - Wikipedia

    en.wikipedia.org/wiki/Thermal_pollution

    Thermal pollution is the rise or drop in the temperature of a natural body of water caused by human influence. Thermal pollution, unlike chemical pollution, results in a change in the physical properties of water. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. [1]
