The leading cause of coral bleaching is rising ocean temperatures due to climate change caused by anthropogenic activities. [3] A temperature about 1 °C (or 2 °F) above average can cause bleaching. [3] The ocean takes in a large portion of the carbon dioxide (CO2) emissions produced by human activity.
Huge stretches of coral reef around the world are turning a ghostly white this year amid record warm ocean temperatures. On Monday, the U.S. National Oceanic and Atmospheric Administration ...
In a 2022 report by the U.N. Intergovernmental Panel on Climate Change, experts determined that just 1.2 C of warming would be enough to severely impact coral reefs, "with most available evidence ...
“The resilience of coral reefs is being tested like never before, and we must prioritize strategies that enhance their ability to withstand climate change,” said Ana Vila Concejo, co-author of ...
Coral reefs around the world are experiencing global bleaching for the fourth time, top reef scientists declared Monday, a result of warming ocean waters amid human-caused climate change. Coral ...
In addition, climate change impacts oceanic currents and sea levels, further altering fish distributions and habitats. Furthermore, ocean acidification , resulting from increased CO2 levels, compromises the ability of shellfish and corals to form shells and skeletons, further endangering marine ecosystems and the communities that depend on them.
Rising sea levels due to climate change requires coral to grow so the coral can stay close enough to the surface to continue the process of photosynthesis. Water temperature changes or disease of the coral [ 56 ] can induce coral bleaching , as happened during the 1998 and 2004 El Niño years, in which sea surface temperatures rose well above ...
The NOAA coral reef authority declared the global bleaching event in April 2024, making it the fourth of its kind since 1998. The previous record from the 2014 to 2017 mass bleaching affected just ...
