Coral bleaching is the process when corals become white due to loss of symbiotic algae and photosynthetic pigments. This loss of pigment can be caused by various stressors, such as changes in temperature, light, or nutrients.
Fuller's earth is the most common spelling today, but both fullers earth and fullers' earth remain in wide use. [4] Fuller's earth is also known by the following other names: Bleaching clay, [5] probably because fulling whitened the cloth. Whitening clay, particularly when used to treat facial pigmentation, such as melasma.
Scientists have found that corals generally begin to bleach when surrounding waters are at least 1 degree Celsius warmer than the maximum average temperature - or the peak of what corals are used ...
Bleaching may be caused by different triggers, including high sea surface temperature (SST), pollution, or other diseases. [57] SST coupled with high irradiance (light intensity), triggers the loss of zooxanthellae , a symbiotic single cell algae that gives the coral its color and the coral's dinoflagellate pigmentation, which turns the coral ...
For example, rising water temperatures are harming tropical coral reefs. The direct effect is coral bleaching on these reefs, because they are sensitive to even minor temperature changes. So a small increase in water temperature could have a significant impact in these environments. Another example is loss of sea ice habitats due

Colin Waters, the chair of the AWG who led the development of the proposal to make the Anthropocene an official part of Earth’s geological history, said the outcome of the vote was “very ...
Canton Island typifies the isolated coral atolls dotting the Pacific Ocean. The Structure and Distribution of Coral Reefs, Being the first part of the geology of the voyage of the Beagle, under the command of Capt. Fitzroy, R.N. during the years 1832 to 1836, was published in 1842 as Charles Darwin's first monograph, and set out his theory of the formation of coral reefs and atolls.
