  2. Causes of climate change - Wikipedia

    en.wikipedia.org/wiki/Causes_of_climate_change

    Air pollution, in the form of aerosols, affects the climate on a large scale. [ 46][ 47] Aerosols scatter and absorb solar radiation. From 1961 to 1990, a gradual reduction in the amount of sunlight reaching the Earth's surface was observed.

  3. Greenhouse effect - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_effect

    How CO 2 causes the greenhouse effect. Matter emits thermal radiation at a rate that is directly proportional to the fourth power of its temperature. Some of the radiation emitted by the Earth's surface is absorbed by greenhouse gases and clouds. Without this absorption, Earth's surface would have an average temperature of −18 °C (−0.4 °F).

  4. Pollution - Wikipedia

    en.wikipedia.org/wiki/Pollution

    Pollution is the introduction of contaminants into the natural environment that cause adverse change. [ 1] Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring ...

    Burning fossil fuels such as coal, petroleum, and natural gas is the leading cause of increased anthropogenic CO 2; deforestation is the second major cause. In 2010, 9.14 gigatonnes of carbon (GtC, equivalent to 33.5 gigatonnes of CO 2 or about 4.3 ppm in Earth's atmosphere) were released from fossil fuels and cement production worldwide ...

  7. Effects of climate change - Wikipedia

    en.wikipedia.org/wiki/Effects_of_climate_change

    Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...

  8. Particulate pollution - Wikipedia

    en.wikipedia.org/wiki/Particulate_pollution

    Particulate pollution is pollution of an environment that consists of particles suspended in some medium. There are three primary forms: atmospheric particulate matter, [ 1] marine debris, [ 2] and space debris. [ 3] Some particles are released directly from a specific source, while others form in chemical reactions in the atmosphere.

  9. Biodiversity loss - Wikipedia

    en.wikipedia.org/wiki/Biodiversity_loss

    Biodiversity loss happens when plant or animal species disappear completely from Earth ( extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
