thoughts about Miami falling into the ocean from rising ocean and hurricanes

My wife was watching something on engineering with relation to Miami being in danger of rising sea levels and hurricanes.
They glossed over hurricanes as waves originating from the coasts of Africa and turning violent from the change in water temperature of the Gulf of Mexico.
Perhaps there would be less hurricanes if there were land masses between Africa and the Gulf of Mexico or if the latter's water temperature was less of contrast to the waves originating from the African coast.
Not sure how to regulate the temperature of the Gulf of Mexico, but canals to the Pacific Ocean could be made and the displaced dirt could be dumped into the ocean to disrupt those currents from the African coast.
Rising sea levels is interesting since it suggests ice melting at the poles.
Perhaps displacing existing ocean water towards inhabitable deserts could lower the sea levels?

I am not denying science by being skeptical of the impact of climate change, but I do think it is silly to believe we can change the climate through relatively minor tweaks in our daily routines.
Carbon Dioxide is a waste product of all oxygen using creatures and is needed for plants which create oxygen as a waste byproduct. Given this model, bring the equilibrium of CO2 in the environment requires either less living creatures or more living plants.
It's a simple worldview. Sure we could alter our consumption of food and energy, but we aren't a third world country where clean water and air conditioning is a rarity.
Americans have adapted. Immigrants coming to the US from third world countries are essentially causing unnecessary increases in CO2 by travelling and becoming part of an energy consuming culture.
