President Barack Obama uses Miami as example at United Nations climate summit
Ocean changes cause Miami Beach flooding, hurt coral reefs off S. Fla.
KEY BISCAYNE, Fla. – In the Florida Keys, under water, coral reefs have been suffering due to global warming, scientists said. And in Miami Beach, dealing with flooding is a lifestyle.
Divers have reported the water temperature shifts underwater. Scientists at National Oceanic and Atmospheric Administration facility in Key Biscayne focus on the issue and express concern.
"No one is immune from climate change," the United Nations Secretary-General Ban Ki-moon said Tuesday in front of world leaders. China and India were among those not present.
President Barack Obama mentioned Miami's flooding problems in his speech at the U.N., Tuesday. Environmental activists nationwide were asking world leaders to recommit to the unsuccessful two-decade long effort to cut green gas emissions.
Obama promised the U.S. would cut emissions to 17 percent by 2020. French President Francois Hollande said his country will invest $1 billion on clean power in poor countries. Dozens of world leaders -- not including China and India -- made a commitment to end deforestation.
Actor Leonardo DiCaprio helped to market the event. But many in South Florida worry about that not being enough.
Manzello said changes in temperature were causing coral reefs -- usually vibrant in color -- to expel nutrients that are vital to their existence. The "heat-stress," he said, causes the corals to weaken and die.
"The amount of live coral and overall health of Florida Keys reef ecosystems has already plummeted to extremely low levels," Manzello said.
