We review the evidence for bio-regulation by coral reefs of local climate through stress-induced emissions of aerosol precursors, such as dimethylsulfide. Coral reefs harbour the highest biodiversity of any ecosystem globally and directly support over 500 million people worldwide, mostly in poor countries. The most diverse coral reef is found around Indonesia. This is suspected to be a major culprit of coral loss. The coral reef that protects their town — an undersea forest of living limestone branches that blunted the storm’s destructive power — had taken a beating. This post was adapted from a Bigelow Laboratory for Ocean Sciences news release. Research shows climate change is already having a huge impact on coral reefs -- a study presented earlier this year estimated that about 70-90% of all existing coral reefs are expected to disappear in the next 20 years due to warming oceans, acidic water and pollution. “The trends we identified in this analysis are exceptionally difficult to detect, yet of the greatest importance in understanding how reefs will change in the coming decades. The research, led by Dr Caitlin Lawson in the Climate Change Cluster at UTS, discovered that across the coral species studied on Heron Island in the southern Great Barrier Reef… The exact composition of most new reefs is currently unknown, due to the expense of collecting genetic and species diversity data. Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria.They typically live in compact colonies of many identical individual polyps.Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.. A coral "group" is a colony of myriad genetically identical polyps. The Center for Biological Diversity sued the Trump administration over lack of habitat protections for these species in August 2019, five years after the corals were initially listed under the Endangered Species Act in 2014. ; They are among the most threatened ecosystems on Earth, largely due to unprecedented global warming and climate changes, combined with growing local pressures. Other threats are caused by people, including pollution, sedimentation, unsustainable fishing practices, and climate change, which is raising ocean temperatures and causing ocean acidification. The largest coral reef biome in the world is found in the Northeast of Australia. The coral reef that protects their town — an undersea forest of living limestone branches that blunted the storm’s destructive power — had taken a beating. The proposed protections in the Pacific cover 230 sq miles (600 sq km) of critical habitat for seven threatened corals around island territories including Guam, American Samoa and the Northern Mariana Islands. The new habitat protections will help regulate local threats to corals like overfishing, pollution, and dredging operations. In fact, scientists estimate that we’ve already lost as much as half of all coral reefs since 1980, and some fear that we could lose the rest in just 30 years. This is allowing drifting coral larvae to settle and grow in new regions. Coral reefs are facing a steep decline today for many reasons, including climate change, overfishing, pollution, disease, and more. In a long-awaited move from the Trump administration, the US has proposed critical habitat protections for twelve coral species in the Caribbean and Pacific Ocean. Coral reefs account for one-third of all biodiversity in the oceans and are vital to humanity. Human activities have caused much of the destruction of the world’s coral reefs.
