- Reporting from Cartagena, Colombia -
effect of climate change is anything but hypothetical to retired
Colombian naval officer German Alfonso. Just ask him about the time his
neighborhood in this historic coastal city became an island.
For five years, Alfonso, 74, has watched tides rise higher and
higher in the Boca Grande section of Cartagena. This month, tides
briefly inundated the only mainland connection to his neighborhood, a
converted sandbar where about 60 high-rise condo and hotel towers have
been built in the last decade or so.
"Before, people thought it a normal phenomenon. But we're becoming
more conscious that something is going on," Alfonso said. "If the sea
keeps rising, traffic could just collapse."
