How Does Climate Change Affect Coral Reefs?

The complex structure of coral reefs is the center of a busy, biodiversity-rich ecosystem. But around the world, algae keeping coral reefs in healthy and colorful condition are being destroyed or killed by rising seawater temperatures and rising levels of carbon dioxide. In Belize, WWF and local nonprofit organizations use coral nurseries to nurture varieties with climate change. And we are planting these new varieties in corrupt coral reefs.

In one of the many coral farms operated by Fragments of Hope, the fragments of healthy elk are associated with structures underwater and grow until ready for transplant.

When they grow big enough corals are transplanted into marine protected areas - usually dead coral structures - and they can begin to rebuild coral reef ecosystem

Climate change is the world's greatest threat to coral reef ecosystems and scientific evidence clearly shows that the Earth's atmosphere and oceans are warming. Climate change affects coral reef ecosystems through sea level rise, changes in frequency and intensity of tropical cyclones, and changes in ocean circulation patterns. In summary, all these effects dramatically change the function of the ecosystem and the products and services that coral reef ecosystems provide to people all over the world. Our infographic describes the process from sea level rise to ocean acidification.

Today's coral reefs are threatened all over the world (ICRI, NOAA, Reefbase). This is not new, but the extent to which coral will die in the world is uneasy. The impact of sustainable climate change, which has a measurable rise in saltwater temperature, directly affects coral reefs as the third global whitening event in 2015/16. This incident led to coral mass deaths (NOAA announced the third global coral bleaching event, ElNiño extended the longest worldwide coral bleaching event)

Coral reefs are expected to experience more frequent whitening phenomena between 2012 and 40 years. The Intergovernmental Panel on Climate Change (IPCC) considers this to be the biggest threat to the coral reef system in the world. Coral reefs around the world are losing 19% and the remaining 60% coral reefs are at risk of direct loss. There are several ways to explain the effect of coral bleaching on coral reefs. The first one is the coral covering, the more corals covering the ground, the less the effect of whitening. Second, coral abundance. This is the number of various creatures of coral reefs.

The most famous example of marine ecosystems at risk of climate change are coral reefs. Coral reefs are the most diverse ecosystems in the ocean, supporting at least hundreds of thousands. Corals are very susceptible to the effects of climate change due to their narrow physiological limits, close proximity to populated areas, and the threats associated with these issues (Hoegh-Guldberg 2005; Knowlton and Jackson 2008). To prevent dangerous ocean storms, millions of people around the world rely on coral reef fishing and tourism to maintain living and coral structures (Hoegh-Guldberg et al., 2007).
