When the Biden administration entered the White House, they identified climate change as a significant security threat. As a result, the US military set in motion a full-scale response to address this. One of their programs aimed to resolve threats brought by the rising sea level and coastal flooding was a program by DARPA called “Reefense.”

Coral Reefs, Rain Forest of the Sea

As reported by IPCC since the 1800s, “emissions of greenhouse gases from human activities are responsible for approximately 1.1°C of warming since 1850-1900 and finds that averaged over the next 20 years, global temperature is expected to reach or exceed 1.5°C of warming.” 

Rising sea levels and coastal flooding have increased drastically in the last 50 years. One natural barrier we have against these is the coral reefs. According to NOAA, “coral reef structure buffers shorelines against waves, storms, and floods, helping to prevent loss of life, property damage, and erosion. When reefs are damaged or destroyed, the absence of this natural barrier can increase the damage to coastal communities from normal wave action and violent storms.

It is estimated that 25% of all marine species call coral reefs their homes. Thus they have been called “the rain forests of the sea.”
