I would agree with you but the water temperature can be regulated to any temperature between 70 and 95 degrees just by opening or closing a gate on the discharge end at the top. The loop current in the gulf is created by the Yucatan and Caribbean currents joining together from the Caribbean Sea. If the tunnels were placed across the Yuctan channel the tunnels would cool all of the Gulf Of Mexico in about 14 days to any temperature. Sorry, I just don't see the harm in it if it can save lifes. When finished just close the gate and let temperatures stabalize again and wait for the next storm to come by then repeat the process.
