    en.wikipedia.org/wiki/Atmospheric_thermodynamics

    Atmospheric thermodynamics is the study of heat-to-work transformations (and their reverse) that take place in the Earth's atmosphere and manifest as weather or climate. . Atmospheric thermodynamics use the laws of classical thermodynamics, to describe and explain such phenomena as the properties of moist air, the formation of clouds, atmospheric convection, boundary layer meteorology, and ...

    en.wikipedia.org/wiki/Climate_change

    CO 2 concentrations over the last 800,000 years as measured from ice cores (blue/green) and directly (black) Greenhouse gases are transparent to sunlight, and thus allow it to pass through the atmosphere to heat the Earth's surface. The Earth radiates it as heat, and greenhouse gases absorb a portion of it. This absorption slows the rate at ...

  7. Causes of climate change - Wikipedia

    en.wikipedia.org/wiki/Causes_of_climate_change

    Energy flows between space, the atmosphere, and Earth's surface. Rising greenhouse gas levels are contributing to an energy imbalance. Factors affecting Earth's climate can be broken down into forcings, feedbacks and internal variations. [14]: 7 Four main lines of evidence support the dominant role of human activities in recent climate change: [17]

  9. Atmospheric optics - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_optics

    This process of reflection/absorption is what causes the range of cloud color from white to black. [19] Other colors occur naturally in clouds. Bluish-grey is the result of light scattering within the cloud. In the visible spectrum, blue and green are at the short end of light's visible wavelengths, while red and yellow are at the long end.
