It's just sunspots.

All the low level places will wash over and come back the next ice age someday.

Florida and the keys, they may awash away, soon as the next huge hurricane comes.

I don't have the link but I've read where scientists estimate a rise of 60 meters is possible everything melts. If you set this map at 60 meters most of Florida, Louisiana and lots of Texas, etc. goes under the Gulf.

Including my house.

A rise of only 2 meters/6 feet would seriously impact the Florida coast, where the majority of its population is located. Long before that, property insurance will be impossible to get. The govt. is phasing out FEMA/govt. subsidized flood insurance for flood prone areas already. And they should. Insane to rebuild when one is in a flood plane. Money is better spent helping people relocate.

Miami and other parts of south Florida are the most vulnerable regions in the world to rising sea levels .... The Florida peninsula is a porous plateau of karst limestone sitting atop bedrock , so the salt water rises from underneath and in places like Miami, already comes up into the city streets from the storm sewers at high tides.

“With six feet of sea-level rise, South Florida is toast,” says Tom Gustafson, a former Florida speaker of the House and a climate-change-policy advocate. Even if we cut carbon pollution overnight, it won’t save us. Ohio State glaciologist Jason Box has said he believes we already have 70 feet of sea-level rise baked into the system.

So if 70 ft or about 23m is baked in, my little beach would be completely covered. What's the rate of sea level rise?

Some parts of the US Coast are actually subsiding/sinking - like Roanoke, VA. Plus because of changes in ocean currents and temps (heated water expands), ocean levels are rising more in some areas than others. Then the more severe storms create higher storm surges. While these surges are temporary, they do tremendous damage.

Here's a detailed article about the flooding/ocean level rise in Norfolk:
(a few excerpts)

Flooding has become so common in this city, where water is the lifeblood, that residents talk about it in the supermarket. Home to the world's largest naval base, Norfolk sits on flat land — much of it filled-in marsh that's now at sea level and sinking. Add to that the sea-level rise from global warming, and the city faces what it deems a $1 billion-plus problem.

Sea level has risen nearly 8 inches worldwide since 1880 but, unlike water in a bathtub, it doesn't rise evenly. In the past 100 years, it has climbed about a foot or more in some U.S. cities because of ocean currents and land subsidence — 11 inches in New York and Boston, 12 in Charleston, 16 in Atlantic City, 18 in Norfolk and 25 in Galveston, Texas, according to a USA TODAY analysis of 2012 tide gauge data collected by the National Oceanic and Atmospheric Administration (NOAA).

If you read the whole article, you will see that many people are desperate, but don't feel they can leave - either because they are underwater with their mortgages (the value of their homes are less than what they owe on their mortgages), or that potential purchasers are (rightly) being warned off from buying in these frequently flooded areas, and/or "But this is where I raised my kids. I love my house. I love my neighbors." Etc. Basically, many people who live in these areas are unable to face the realities of global climate change, take their losses and get out of Dodge before the next hurricane's storm surge destroys their low-lying homes and they can no longer get any property insurance. I can understand that - the reality is so horrifying, difficult to comprehend and accept, and they don't see anyway out other than writing off their homes and way of life.

What may help turn the tide, figuratively, is the coming surge in flood insurance costs, says Leonard Berry, director of the Florida Center for Environmental Studies at Florida Atlantic University. He says higher premiums might do more than hurricanes to change people's attitudes about living by the water.

Congress passed a 2012 law that, in October, began phasing out subsidies for the debt-ridden federal flood insurance program. More than a million homeowners could see sticker shock.

"There will be a slow exodus" from the coasts as property values gradually sink, predicts oceanographer John Englander, author of High Tide on Main Street. By century's end, he says, sea-level rise could dramatically transform U.S. coastlines, pushing them inland by hundreds of feet.

Roanoke is 1000 feet up in Western VA.

At first I thought you meant 60 cm.


The main ice covered landmass is Antarctica at the South Pole, with about 90 percent of the world's ice (and 70 percent of its fresh water). Antarctica is covered with ice an average of 2,133 meters (7,000 feet) thick. If all of the Antarctic ice melted, sea levels around the world would rise about 61 meters (200 feet). But the average temperature in Antarctica is -37°C, so the ice there is in no danger of melting. In fact in most parts of the continent it never gets above freezing.

Not the best source, I know.

Micronesia is a vast island nation with an ancient culture that includes 607 islands, scattered across a million square miles of the western Pacific. A rise of even one meter (three feet) would render most of these islands uninhabitable. More from the OP:

Even the dead are no longer safe in my country," Micronesia's Ambassador to the UN told ABC News at his mission's offices on a rainy day in New York. He gave us recent digital photos of his home islands. In one, a man stands shin-deep out in a calm and sunny sea ... where a cemetery used to be. In others, colorful traditional burial grounds spill out of a wave-eroded bank onto the tiny remaining beach, and water surges inland past tumbled houses.

And excerpts from a 2009 report:
A rising water table is already turning salty in the center of islands, killing staple food crops like taro, and many other kinds of plants. "Sea level rise is the most scary -- you cannot put sea walls on all the islands -- about 600 of them. 500 are small islands like atoll islands," said Nakayama.

The World Has 'Written Us Off'
Micronesia's culture is ancient. Its people, say historians, arrived about 3,500 years ago.
"It's going to be very sad for us to lose all that ancestry and homes -- where we've grown and maintain our culture," Nakayama said.

"Where will you go?" we asked. "We don't want to go anywhere," he answered. "We want to stay on our islands, and this is what we want the international community to understand.
"I feel they have written us off because the kind of targets they are putting on the table is not going to save the islands," said the ambassador.

Not all the islands are flat, but fishing being a major source of food, many people had homes built right on the beaches. The much eroded volcanic hills on the islands are very steep, and severe storms result in landslides - another reason many people built on the beach in small, traditional villages. And we're talking extremely poor people and the houses were more like huts. There are only 2 very modest land-based "hotels". (I was there to scuba dive on the WW II wrecks and stayed on a live-aboard diveboat.) Incredibly beautiful part of the world but oppressively humid and hot.
