In Recent Years, Deadly Coral Bleaching Events Have Increased on Reefs

In recent years, deadly coral bleaching events have increased on reefs around the world.This increase is strongly correlated with rising reef temperatures.The worst bleaching events occur in years when an El Niño weather event occurs, causing even higher spikes in reef temperatures.Based on this evidence, one can conclude that El Niño weather events likely

A) are the cause of coral bleaching, rather than climate change.
B) cause greater coral bleaching than climate change.
C) amplify the effects of climate change by further increasing reef temperatures.
D) cause less coral bleaching than climate change does.
E) would not affect coral reefs unless climate change was also occurring.
