A few geographical home thinks, if sea level because earthly climate is heated and continue to lift, after a few years, float clough can lose the value of existence. And the person that supports clough however not so look. They point out, float clough can deal tomorrow completely 100 years 50 centimeters heighten measures sea level, besides still is 50 centimeters merely relatively pessimistic calculate number. The person that opposes clough puts forward again, this kind forecasts oversight rainfall. The influence of river flow and monsoon, and after these elements can make the water level of lagoon is shut in clough, rise. Italian government still supports clough project, after all this project can make sure people is avoided inside very long period of time suffer the flood to invade. Of course, the people that supports this project also is not not was anxious, they are being designed a few lift in the light of sea level of the risk answer program. But anyhow, they still are to this one project very confident, someone of no less than says in that way: Lift when sea level 20 centimeters when, perhaps Venice can be the place of Italian only safety.
