Answer:
Hurricane Katrina is an effect of C. Global Climate Change.
Step-by-step explanation:
Due to global warming, warm winds with high speed showed a strong impact on United States coast. Along the coast, typically coastal cities are below sea-level. These are protected by the defense walls called Levees.
With the high-speed winds, huge waves are generated pushing the water levels around the city, New Orleans in 2005. Despite the defense walls, high-end waves lashed the sea-port. New Orleans, Louisiana were the most damaged cities after the hurricane. This left a legacy of death and destruction in United States history.
