Say goodbye to Miami and New Orleans. No matter what we do to curb global warming Wholesale Florida State Seminoles Shirts , these and other beloved US cities will sink below rising seas, according to a study.

But making extreme carbon cuts and moving to renewable energy could save millions of people living in iconic coastal areas of the United States, said the findings in the October 12 edition of the Proceedings of the National Academy of Sciences, a peer-reviewed US journal.

Scientists have already established that if we do nothing to reduce our burning of fossil fuel up to the year 2100, the planet will face sea level rise of 14-32 feet (4.3?9.9 meters), said lead author Ben Strauss, vice president for sea level and climate impacts at Climate Central.

The big uncertainty is the issue of when.

"Some of this could happen as early as next century Wholesale Clemson Tigers Shirts ," Strauss told AFP.

"But it might also take many centuries," he added.

"Just think of a pile of ice in a warm room. You know it is going to melt, but it is harder to say how quickly."

To bring this issue home for people in the United States, the study pinpoints at-risk land where more than 20 million people reside.

The authors projected business-as-usual carbon emissions, in addition to the complication of the melting West Antarctic ice sheet, a process some experts fear is irreversible.

They also considered what might happen if the world were to make a big turnaround, reaching peak carbon emissions by 2020.

This radical scenario would have to occur far earlier than the current aim of some world powers to peak by 2050 Wholesale Auburn Tigers Shirts , said Strauss.

An online tool at Climate Central allows users to see the impacts on various US cities. A global version is expected in the next month, Strauss said.

- Too late? -

The tool shows which US cities may face "lock-in dates beyond which the cumulative effects of carbon emissions likely commit them to long-term sea-level rise that could submerge land under more than half of the city's population," said the study.

"Norfolk, Virginia, for example, faces a lock-in date of 2045 under a scenario of unabated carbon emissions."

For cities like Miami and New Orleans, the limits are already exceeded.

"In our analysis Wholesale Alabama Crimson Tide Shirts , a lot of cities have futures that depend on our carbon choices but some appear to be already lost," Strauss said.

"And it is hard to imagine how we could defend Miami in the long run."

Miami's low elevation and porous limestone foundation mean that sea walls and levees will not help, he said.

The state of Florida has the most number of big cities at risk from sea level rise, holding 40 percent or more of the US population living on potentially affected land.

After Florida, the next three most affected states are California, Louisiana and New York.

One beloved American city, New Orleans Wholesale Wisconsin Hoodies , home to jazz music and some of the nation's most beloved cuisine, is already sinking.

"New Orleans is a really sad story," Strauss said.

"It is a lot worse looking than Miami."

New York is also in peril, and under a worst-case scenario, the city could be consigned to an un-livable future by the year 2085, according to the study.

But strong action -- the kind that would reduce carbon emissions in the year 2050 to levels that more closely resemble those seen in 1950 -- could make a difference.

A total of 14 cities with more than 100,000 residents could avoid locking in this century Wholesale West Virginia Mountaineers Hoodies , including Jacksonville, Florida; Chesapeake, Norfolk, and Virginia Beach in Virginia; and Sacramento and Stockton in California.

"We were really trying to show what the consequences of our carbon choices are going to be," said Strauss, whose study was co-authored by the Potsdam Institute for Climate Impact Research in Germany and edited by renowned NASA climate scientist and author James Hansen.

According to earth scientist Michael Mann, a well-known author on climate change Wholesale Usc Trojans Hoodies , the latest findings are a "useful contribution to the literature."

The study provides a "better quantification of the detrimental impacts of the magnitude of sea level rise we may commit to in the decades ahead if we continue with business-as-usual policies of fossil fuel burning," said Mann, who was not involved in the research.

Northwest China's Shaanxi Province is set to host the First International Apple Symposium on Monday as the region aims to produce one-seventh of the world's apples by the end of this year.

According to a press conference in Beijing on Sunday, the symposium will be held from Monday to October 16 in the cities of Yangling and Yan'an, Shaanxi Province. The symposium will be attended by more than 1,000 representatives from governments and enterprises, as well as 150 experts from more than 30 countries and regions.

According to Bai Qinyi Wholesale Ucla Bruins Hoodies , head of Shaanxi's agriculture department, the province aims to expand its apple plantation area to 733,333 hectares by the end of this year, boosting its annual apple production to 11 million tons.

The crop will account for one-fourth of China's apple production.

The province also vows to increase its apple production to 12 million tons by the end of 2020.

According to statistics released at the press conference, Shaanxi exported 510,000 tons of apples in the first half of this year. The province has exported apples to 80 countries and regions and has in recent years tapped into markets in India, Nepal Wholesale Texas Longhorns Hoodies , Pakistan, Russia, Bangladesh and Myanmar, all of which are along the Silk Road economic belts.

Of the 37 million people in Shaanxi, roughly 10 million, or 27 percent, work in apple-related industries Wholesale South Carolina Gamecocks Hoodies , said Bai. Fruit-related industries contributed 37.5 billion yuan (5.77 billion) worth of added value in Shaanxi in 2015 and helped lift farmers in 44 counties out of poverty.

The province is also said to be the largest apple cider processing base in the world.
