The Climate Change and Coral Reefs working group at the Center for Ocean Solutions, internationally respected collaborative, scientific research group out of California, studies the impact of rising temperatures, ocean acidification and sea-level rise on coral reefs. During July 2011 through July 2013, the working group drafted a message:
"The working group concluded that vast agreement exists among reef scientists about the importance, magnitude, and sources of many of the problems that face coral reefs around the world. Through extensive discussions about coral adaptation, biogeochemistry, calcification, and population dynamics in the face of multiple co-occurring stressors, the group concluded that sufficient understanding exists to voice a clear message. Due to emissions of carbon dioxide and other greenhouse gases—in combination with local stresses such as pollution, run-off from land, habitat destruction, and overfishing—coral growth and vitality are compromised and less resilient to further pressures. Ultimately reef preservation requires immediate and strong actions at both global and local scales. While global emissions are the primary driver, the critical message is that action at the local level can substantially reduce vulnerability of reefs to climate change impacts."

Why should Coral Reefs be protected?
They are among the oldest ecosystems on Earth
They support a great diversity of species
Provide sources of food and shelter
Ecosystems support a variety of human needs: subsistence, fisheries, tourism, coastal protection and new drug compounds (HIV, cardiovascular diseases, etc.)
They form natural barriers that protect the coasts against erosion
They cover less than 1% of the Earth's surface but contain 25% of marine fish species (Burke et al., 1998)
At least 500 million people rely on coral reefs for food, coastal protection and livelihoods (Wilkinson 2004)
They provide about $ 375 billion per year worldwide in goods and services
About 20% of the world's coral reefs have been destroyed in recent decades and 20% or more are severely degraded (WRI 2006)
A Solution: Coral Propagation
Conservation initiatives all over the world are trying to restore coral reefs by breeding coral specimens to be out-planted in regenerating reefs. Nature Now visited and worked with Costa Rican Non-Profit, Raising Coral, to learn more.
Contributing to REEF’s online database, from which a variety of reports can be generated on species distribution and population trends, for a specific reef or large geographic regions.
Students trained to conduct Roving Diver Technique (RDT), a visual survey method while snorkeling to classify reef fish and turtles, entered into REEF.org.
