"There are ways for us to make coastal communities more livable, resilient and viable post-disaster, just by making the whole community more resilient ... so that businesses and government services can all get back to work more quickly after a disaster," said Pat Forbes, executive director of Louisiana's Office of Community Development, which produced the report along with the Foundation for Louisiana.
In other areas, people will have little choice but to leave as the water rises. The plan, in a departure from many adaptation reports, also focuses on how inland areas can prepare for an influx of new residents from the coasts.
"There's a sort of self-displacement that's occurring over the past 15 years or so," Forbes said. As large numbers of people move out of coastal communities, the shift is likely a sign that they are sick of flooding, worried about inability to get to schools or jobs or unable to pay rising flood insurance rates. "I'm sure it's a combination of all those things and more," he said.

What Is the Window of "Creeping Normality"?
The fable of the boiling frog holds that if you drop a frog into a pot of boiling water it will instantly leap back out but if you put that frog in a pot of cold water and heat it gradually it will just remain there until it's cooked. Some people consider that a metaphor for the human race in the age of rapid climate change.
How abrupt and jarring does climate change have to become before it causes us to respond with demands for immediate action? If we don't react how long before it becomes our new normal, just another part of our world and our environment?
In Calgary we saw two "once a century" floods in just eight years, almost back to back. There's a similar pattern of recurrence in many parts of the United States and Europe. Our heated atmosphere contains, by some estimates, about 14% more water vapour than we had as recently as 1980. When you consider that water vapour is the most powerful greenhouse gas that's an awful lot. The warmer, moister atmosphere also provides powerful fuel for hurricanes and other storm events of increasing frequency, intensity and duration. That also changes precipitation patterns. Normally wet areas get wetter, dry areas become drier. Flood and drought with fluke variations in both areas.
In the main our authorities still prefer to respond to these impacts in the same way that made sense as recently as the 1980s - declare a disaster and send disaster relief followed by cheques to help reconstruction. Yet as natural disasters become more commonplace and recurrent it saps the government's ability to keep writing cheques. Eventually it has to become every man for himself.
In today's Guardian is a report that across coastal America, high tide flooding has doubled in the past 30 years. Doubled, and the situation is worsening. It's a combination of several factors including sea level rise, worsening severe storm events, and coastal infrastructure that was designed and built to meet far milder conditions. But they don't have to wait for Hurricane Sandy events any more. Now they get "Sunny Day" flooding from high tides alone.
...these events swamp streets and homes with water simply from the incoming tide, without the aid of a storm. Noaa said that in 2017 areas across the US north-east and Gulf of Mexico were worst hit, with Boston, Massachusetts, and Atlantic City, New Jersey, both experiencing 22 days of flooding, while Galveston, in Texas, was soaked on 18 different days.
The longer-term trend is even more certain, Noaa said, with melting glaciers, thermal expansion of sea water and altered ocean currents pushing the sea level steadily higher and causing further floods.
“Breaking of annual flood records is to be expected next year and for decades to come as sea levels rise, and likely at an accelerated rate,” the report states. “Though year-to-year and regional variability exists, the underlying trend is quite clear: due to sea level rise, the national average frequency of high tide flooding is double what it was 30 years ago.”
“There’s a clear upwards trend of this type of flooding,” said Andrea Dutton, a geologist at the University of Florida. “Extreme events like hurricanes may be the breaking point but this sort of frequent flooding is the taste of what is coming in the future on a permanent basis. We need to rethink our relationship with the coastline because it’s going to be retreating for the foreseeable future.”
Dutton said that south Florida, where weather forecasts in some places now come with tidal warnings, and fish are a regular sight on flooded roads, is particularly vulnerable. The low-lying region sits on porous limestone, which pushes up floodwater from underground, and many communities are unable to easily retreat because they back on to the Everglades wetlands.But that's where we can thank our lucky stars that we have governments to protect us. What's that? They won't?
“They used to get just one day a year of tidal flooding, now it’s two months of it in the fall,” she said. “Engineering can help delay things but ultimately the oceans will win. We are going to have to live with the water.”
Despite the risk posed to the US by sea level rise and flooding events, there is no national plan to deal with the issue, with much of the adaption work left to states and counties. The Trump administration has rescinded previous rules to build federally funded infrastructure with climate change in mind and has sought to reverse various measures aimed at taming global warming.
“We need to take this report as a warning to prepare ourselves, or we will just sit around [like the frog in the pot] and wait for disaster to happen,” Dutton said.
Canada's frog is dozing in that same pot. The east coast is particularly vulnerable. Ports are built down to the waterline, to the boats. The wharfs and quays and jetties weren't designed with sea level rise in mind. Neither were waterfront homes and buildings, roads and utilities. Replacing all that in a retreat from the sea is going to be bloody costly. Yet most international trade in goods is carried in the holds of ships. This photo gives an idea of what the port of Halifax can expect from 3 degrees Celsius of warming.
That's where creeping normality can turn dangerous when it lulls us into complacency, encouraging us not to act in time.

"There Was No Rain"
Climate change refugees are on the march and they're coming not just from Africa or the Middle East or some low-lying atoll in the South Pacific, they're migrating poleward in the Americas too.
Todd Miller went to southern Mexico to interview climate migrants. Where are they from? Where are they headed? Given the dangers, why?
When I first talked to the three Honduran men in the train yard in the southern Mexican town of Tenosique, I had no idea that they were climate-change refugees. We were 20 miles from the border with Guatemala at a rail yard where Central American refugees often congregated to try to board La Bestia (“the Beast”), the nickname given to the infamous train that has proven so deadly for those traveling north toward the United States.
...
When I asked why they were heading for the United States, one responded simply, “No hubo lluvia.” (“There was no rain.”) In their community, without rain, there had been neither crops, nor a harvest, nor food for their families, an increasingly common phenomenon in Central America. In 2015, for instance, 400,000 people living in what has become Honduras’s “dry corridor” planted their seeds and waited for rain that never came. As in a number of other places on this planet in this century, what came instead was an extreme drought that stole their livelihoods.
For Central America, this was not an anomaly. Not only had the region been experiencing increasing mid-summer droughts, but also, as the best climate forecasting models predict, a “much greater occurrence of very dry seasons” lies in its future. Central America is, in fact, “ground zero” for climate change in the Americas, as University of Arizona hydrology and atmospheric sciences professor Chris Castro told me. And on that isthmus, the scrambling of the seasons, an increasingly deadly combination of drenching hurricanes and parching droughts, will hit people already living in the most precarious economic and political situations. Across Honduras, for example, more than76% of the population lives in conditions of acute poverty. The coming climate breakdowns will only worsen that or will, as Castro put it, be part of a global situation in which “the wet gets wetter, the dry gets drier, the rich get richer, the poor get poorer. Everything gets more extreme.”

The only real preparations for such a world are grim ones: walls and the surveillance technology that goes with them. Most climate-displaced people travelling internationally without authorization will sooner or later run up against those walls and the armed border guards meant to turn them back. And if the United States or the European Union is their destination, any possible doors such migrants might enter will be slammed shut by countries that, historically, are the world’s largest greenhouse gas polluters and so most implicated in climate change. (Between 1850 and 2011, the United States was responsible for 27% of the world’s emissions and the countries of the European Union, 25%.)
...
Only 15 years ago, very little of this existed. Now, the whole region -- and most of this preceded Donald Trump’s election victory -- has become a de facto war zone. Climate refugees, having made their way through the checkpoints and perils of Mexico, will now enter a land where people without papers are tracked in complex, high-tech electronic ways, hunted, arrested, incarcerated, and expelled, sometimes with unfathomable cruelty. To a border agent, the circumstances behind the flight of those three Honduran farmers would not matter. Only one thing would -- not how or why you had come, but if you were in the United States without the proper documentation.
Climate change, increased global migration, and expanding border enforcement are three linked phenomena guaranteed to come to an explosive head in this century. In the United States, the annual budgets for border and immigration policing regimes have already skyrocketed from about $1.5 billion in the early 1990s to $20 billion in 2017, a number that represents the combined budgets of Customs and Border Protection (CBP) and Immigration and Customs Enforcement. During that period, the number of Border Patrol agents quintupled, 700 miles of walls and barriers were constructed (long before Donald Trump began talking about his “big, fat, beautiful wall”), and billions of dollars of technology were deployed in the border region.
As Paul Currion points out, even some countries that are only comparatively wealthy are building such “walls,” often under pressure and with considerable financial help. Take Turkey. Its new “smart border” with drought-stricken and conflict-embroiled Syria is one of many examples globally. It now has a new tower every 1,000 feet, a three-language alarm system, and “automated firing zones” supported by hovering zeppelin drones. “It appears that we’ve entered a new arms race,” writes Currion, “one appropriate for an age of asymmetric warfare, with border walls replacing ICBMs [intercontinental ballistic missiles].”
India is typical in constructing a steel wall along its lengthy border with Bangladesh, a country expected to have millions of displaced people in the decades to come, thanks to sea level rise and storm surges. In these years, with so many people on the move from the embattled Greater Middle East and Africa, the countries of the European Union have also been doubling down on border protection, with enforcement budgets soaring to 50 times what they were in 2005.
The trends are already clear: the world will be increasingly carved up into highly monitored border surveillance zones. Market projections show that global border and homeland security industries are already booming across the planet. The broader global security market is poised to nearly double between 2011 and 2022 (from $305 billion to $546 billion). And, not so surprisingly, a market geared to climate-related catastrophes is already on the verge of surpassing $150 billion.
This is the world that Gwynne Dyer described a decade ago in his book, "Climate Wars: The Fight for Survival As the World Overheats." In it, the author describes how the Pentagon plans to militarize America's coasts and land borders (to the south anyway). He also notes that American military planners are looking at ideas such as robotic, free fire killing zones where, out of sight and out of mind, would be migrants will be slaughtered.
It's fair to say that many Americans, perhaps most, are already conditioned, pre-disposed to see the brown peoples to their south as a peril. Trump tells them these illegals are rapists and worse. The time-honoured steps to dehumanize a targeted group are well underway and they're finding a receptive audience.
Also bear in mind what is happening in American society. The nation is being fractured, left (or what passes for left down there) and right. Some claim the American people haven't been so deeply divided since the Civil War. Social cohesion is being undermined and, to some extent, deliberately. The US has the highest rates of inequality - of wealth, income and opportunity - among the developed nations. There is a gaping divide between the plutocracy on one side and the precariat on the other. Some see in this the emergence of a true aristocracy and the evolution of a state of neo-feudalism. White supremacists and fascists now march freely through America's streets. These shifts do not a welcoming society engender.
Another powerful factor that will come into play will be the climate change plight that will be experienced by the American people across the southern states. Climatically everything is worsening. Severe storm events, hurricanes and tornadoes of worsening intensity. Severe weather events, floods and droughts, of increasing frequency, duration and intensity. The depletion of once abundant groundwater resources. Worsening heat events and fires. Sea level rise, storm surges and saltwater inundation. America is facing the real prospect of dealing with an internally displaced population, IDPs. In a country with America's standard of living that can be a hugely costly burden on the state, especially one that is now in the process of being defunded through tax "reform" and other bleed off mechanisms. If the society has to struggle to resettle its own IDPs, how likely is it to be welcoming to climate migrants from other lands?
