First evidence of surprising ocean warming around Galápagos corals

Researchers found that the northern Galápagos Islands have been warming by almost 0.4 degrees F per decade, with temperatures increasing overall by about 1.1 degrees F since the 1970s. This finding is significant because it suggests that the region's reefs are more vulnerable to climate change than previously thought.
