Civilization collapse in the climate-devastated world, by @DavidOAtkins

With “shock and awe,” our military had unleashed the end of the world on a city of six million — a city about the same size as Houston or Washington. The infrastructure was totaled: water, power, traffic, markets and security fell to anarchy and local rule. The city’s secular middle class was disappearing, squeezed out between gangsters, profiteers, fundamentalists and soldiers. The government was going down, walls were going up, tribal lines were being drawn, and brutal hierarchies savagely established.

I was a private in the United States Army. This strange, precarious world was my new home. If I survived.

Two and a half years later, safe and lazy back in Fort Sill, Okla., I thought I had made it out. Then I watched on television as Hurricane Katrina hit New Orleans. This time it was the weather that brought shock and awe, but I saw the same chaos and urban collapse I’d seen in Baghdad, the same failure of planning and the same tide of anarchy. The 82nd Airborne hit the ground, took over strategic points and patrolled streets now under de facto martial law. My unit was put on alert to prepare for riot control operations. The grim future I’d seen in Baghdad was coming home: not terrorism, not even W.M.D.’s, but a civilization in collapse, with a crippled infrastructure, unable to recuperate from shocks to its system.

And today, with recovery still going on more than a year after Sandy and many critics arguing that the Eastern seaboard is no more prepared for a huge weather event than we were last November, it’s clear that future’s not going away.

This March, Admiral Samuel J. Locklear III, the commander of the United States Pacific Command, told security and foreign policy specialists in Cambridge, Mass., that global climate change was the greatest threat the United States faced — more dangerous than terrorism, Chinese hackers and North Korean nuclear missiles. Upheaval from increased temperatures, rising seas and radical destabilization “is probably the most likely thing that is going to happen…” he said, “that will cripple the security environment, probably more likely than the other scenarios we all often talk about.’’

Locklear’s not alone. Tom Donilon, the national security adviser, said much the same thing in April, speaking to an audience at Columbia’s new Center on Global Energy Policy. James Clapper, director of national intelligence, told the Senate in March that “Extreme weather events (floods, droughts, heat waves) will increasingly disrupt food and energy markets, exacerbating state weakness, forcing human migrations, and triggering riots, civil disobedience, and vandalism.”

On the civilian side, the World Bank’s recent report, “Turn Down the Heat: Climate Extremes, Regional Impacts, and the Case for Resilience,” offers a dire prognosis for the effects of global warming, which climatologists now predict will raise global temperatures by 3.6 degrees Fahrenheit within a generation and 7.2 degrees Fahrenheit within 90 years. Projections from researchers at the University of Hawaii find us dealing with “historically unprecedented” climates as soon as 2047. The climate scientist James Hansen, formerly with NASA, has argued that we face an “apocalyptic” future. This grim view is seconded by researchers worldwide, including Anders Levermann, Paul and Anne Ehrlich, Lonnie Thompson and many, many, many others.

This chorus of Jeremiahs predicts a radically transformed global climate forcing widespread upheaval — not possibly, not potentially, but inevitably. We have passed the point of no return. From the point of view of policy experts, climate scientists and national security officials, the question is no longer whether global warming exists or how we might stop it, but how we are going to deal with it...

Now, when I look into our future — into the Anthropocene — I see water rising up to wash out lower Manhattan. I see food riots, hurricanes, and climate refugees. I see 82nd Airborne soldiers shooting looters. I see grid failure, wrecked harbors, Fukushima waste, and plagues. I see Baghdad. I see the Rockaways. I see a strange, precarious world.

Our new home.

The human psyche naturally rebels against the idea of its end. Likewise, civilizations have throughout history marched blindly toward disaster, because humans are wired to believe that tomorrow will be much like today — it is unnatural for us to think that this way of life, this present moment, this order of things is not stable and permanent. Across the world today, our actions testify to our belief that we can go on like this forever, burning oil, poisoning the seas, killing off other species, pumping carbon into the air, ignoring the ominous silence of our coal mine canaries in favor of the unending robotic tweets of our new digital imaginarium. Yet the reality of global climate change is going to keep intruding on our fantasies of perpetual growth, permanent innovation and endless energy, just as the reality of mortality shocks our casual faith in permanence.

The biggest problem climate change poses isn’t how the Department of Defense should plan for resource wars, or how we should put up sea walls to protect Alphabet City, or when we should evacuate Hoboken. It won’t be addressed by buying a Prius, signing a treaty, or turning off the air-conditioning. The biggest problem we face is a philosophical one: understanding that this civilization is already dead. The sooner we confront this problem, and the sooner we realize there’s nothing we can do to save ourselves, the sooner we can get down to the hard work of adapting, with mortal humility, to our new reality.

The choice is a clear one. We can continue acting as if tomorrow will be just like yesterday, growing less and less prepared for each new disaster as it comes, and more and more desperately invested in a life we can’t sustain. Or we can learn to see each day as the death of what came before, freeing ourselves to deal with whatever problems the present offers without attachment or fear.
