Ocean Acidification May Contribute To Global Shellfish Decline.
Port Royal, the City underwater in the caribbean.
One scenario that has already happened in the Caribbean
This is a city in the Caribbean that sank in the sea due to a sudden quake, which caused a change in climate and sea level in many nearby coastal areas were probably under water so far.

I considered this information from Stony Brook University is a very importat scientific research for caribbean because we are in one of the sea with the most increasingly acid rate Ph and dead zones, including Golf of Mexico, where the Gulf Stream make his global modulation linked to the ocean life and atmospheric of the whole planet.
Actually it could be probed to considered the rising level in the coast of California, for example, mainly to the industrial activity and acidification that is one factor involved in the very wide and complex process of global climatic change, you need to take in account so many condition and variables of the weather and the ecosystem based on acidification because it coul be considered, too, as another influences over the hurricanes season, for example,and more, no only in the supplies of sea food for caribbeans, if not in the rising sea level probably for local scenaries in the next decades.
The concern is that the afection of alimentary chain in the caribbean area has a link with the regime of raining and completed weather, it could be affect the Gulf Stream with a direct impact in London overflow season and Norge climate, then, in the next future, no only we need to relocalizate cities as Tampa based on director planning of the City manager, but in London and Norge. by the same reason, too.
Several cities near to the caribbean coast will be underwater, maybe, in the next future.
But how do we can know when and where we need to move to be safe and wich is the way to be "safe" for the next generations in London and Norge?
If I am a City manager in coast area of caribbean or England would I may ask my self how I can planning the scenary of the city developing in the next decades in order not to waste money and resource that could be underwater in the next future?
I considered that only science and enginnering data interchange could be considered the way to be pretty close to the true, because, as happens in New Orleans of happens in Port Royal, you never knows... Gualterio Nunez Estrada, Sarasota, Florida, 34233.
In one of the first studies looking at the effect of ocean acidification on shellfish, Stephanie Talmage, PhD candidate(in the picture), and Professor Chris Gobler showed that the larval stages of these shellfish species are extremely sensitive to enhanced levels of carbon dioxide in seawater.
"On Long Island there are many aquaculturists who restock local waters by growing shellfish indoors at the youngest stages and then release them in local estuaries," said Talmage. "We might be able to advise them on ideal carbon dioxide conditions for growth while larvae are in their facilities, and offer suggestions on release times so that conditions in the local marine environment provide the young shellfish the best shot at survival."APA MLA

Although levels of carbon dioxide in marine environments will continue to rise during this century, organisms in some coastal zones are already exposed to high levels of carbon dioxide due to high levels of productivity and carbon input from sources on land.
"This could be an additional reason we see declines in local stocks of shellfish throughout history," said Talmage. "We've blamed shellfish declines on brown tide, overfishing, and local low-oxygen events. However it's likely that ocean acidification also contributes to shellfish declines."
