Albedo (/ æ l ˈ b iː d oʊ / al-BEE-doh; from Latin albedo 'whiteness') is the fraction of sunlight that is diffusely reflected by a body. It is measured on a scale from 0 (corresponding to a black body that absorbs all incident radiation) to 1 (corresponding to a body that reflects all incident radiation).
Land-use change alters not just atmospheric CO 2 concentration but also land surface biophysics such as albedo and evapotranspiration, both of which affect climate. [19] The impact of land-use change on the climate is also more and more recognized by the climate modeling community.

The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).

Ice–albedo feedback is a climate change feedback, where a change in the area of ice caps, glaciers, and sea ice alters the albedo and surface temperature of a planet. Because ice is very reflective, it reflects far more solar energy back to space than open water or any other land cover . [ 1 ]
The interaction between cloud formation and climate change is an aspect of atmospheric science. Clouds have a dual role [6] in the Earth's climate system: they can cool the Earth's surface by reflecting incoming solar radiation (albedo effect) and warm it by trapping outgoing infrared radiation (greenhouse effect). The overall impact of clouds ...
In meteorology and climatology, global and local temperatures depend in part on the absorption of radiation by atmospheric gases (such as in the greenhouse effect) and land and ocean surfaces (see albedo). In medicine, X-rays are absorbed to different extents by different tissues (bone in particular), which is the basis for X-ray imaging.
