Antarctic loss and damage

November 11th marked the beginning of the annual United Nations Framework Convention on Climate Change (UNFCCC)—this year held in Warsaw. Six major components generally comprise the UNFCCC agenda, but two main pillars get the most attention: mitigation and adaptation. The focus on mitigation means nations—developed and developing (naturally there is some contention between rich and poor nations here)—reducing their greenhouse gas emissions to curb the intensity of climate change. As part of the Cancun Agreements, countries agreed to target a reduction in GHG emissions sufficient to keep global temperature increases within 2°C. An ambitious goal, perhaps overly so, to say the least. Adaptation, on the other hand, speaks to the idea that some degree of climate change is inevitable at this point and that nations need to make plans to deal with long-term impacts like sea level rise on behalf of vulnerable people and areas.

Subsumed by the adaptation pillar, the Warsaw Conference has largely centered on the notion of “loss and damage.” In essence, loss and damage related to climate change means losses of life, territory, economic prosperity, climatic stability and predictability, biodiversity etc., and damages related to weather events like Typhoon Haiyan in the Philippines and onset of sea level rise. Some analysts have suggested that loss and damage deserves to be considered a third pillar all its own next to mitigation and adaptation.

In pragmatic terms, discussion of loss and damage ultimately becomes a discussion of culpability, liability, responsibility, and compensation. Sticky territory to be sure. Money politics surrounding loss and damage is contentious at best. No one wants to pay more than their fair share, but few agree on how to determine what shares are “fair.” In large part, the divergence is one between the relative importance of cumulative v. annual GHG emissions, and which should receive more emphasis in establishing financial obligations—basically the same question that stopped the US from signing the Kyoto Protocol. In either case the debate revolves around two major players—the United States (the largest cumulative GHG emitter by far) and China (now the largest annual GHG emitter). Obviously other countries (Europe and the other BRIC nations) have their hands in this issue as well, but the US and China are the big two.

So loss and damage—clearly a salient issue. Climate change means unprecedented losses and damages. When it comes to nations, determining relative interests are somewhat intuitive. Everyone has, albeit varying, national interests in addressing climate change for domestic reasons, and no one wants to pay more than their fair share—no one likes the idea of other countries freeloading on their mitigation efforts. But, clearly, climate change isn’t just a domestic issue. Climate change entails a slew of international losses and damages involving global commons—the oceans and Antarctica, for example—which don’t have straightforward national borders to delineate interest groups and stakeholders. Indeed, Antarctica has plenty to lose and damage to incur, but lacks the domestic interest element, strictly speaking. The Antarctic meltdown has, for the most part, only been discussed indirectly in terms of sea level rise.

But Antarctica has more going on than just melting glaciers, break-away icebergs, and contributions to sea level rise. I’m thinking, for instance, about changes in biodiversity we can expect to see as ecological conditions shift on and around the continent and Southern Ocean. Between rising atmospheric temperatures, ocean acidification, and a warming Southern Ocean, the ~16,000 species known to inhabit Antarctic itself or the waters surrounding it have some notable challenges ahead—but no national  interest, strictly speaking, to represent them at the UNFCCC. In particular, let’s consider some charismatic mega-fauna like the endangered Southern Elephant Seal and the variety of endangered whales that live on and near Antarctica and the Southern Ocean. Sealing and whaling (especially whaling) have been—and still are, sadly—problems for these populations, and climate change coupled with habitat loss and changes in ocean temperatures and acidity will only increase their stressors. If the West Antarctic Ice Sheet melts, then Southern Elephant Seals lose breeding grounds, and whales and seals alike will need to adapt to changing oceanic conditions. So what’s to be done on their behalf? While Antarctic interests are represented at the UNFCCC by non-governmental organization (NGO) observers, Antarctica doesn’t exactly have its own seat at the table.

Luckily, Antarctica will benefit from mitigation efforts regardless of whether it’s afforded explicit attention or not—but ethically speaking, because improvements to Antarctica’s lot are, in a mitigative sense, coincidental or happenstantial, this may be unsatisfying. And few—perhaps with the exception of some researchers and activists—worry about Antarctic adaptation. So, again, what’s to be done to hedge against Antarctic loss and damage?

To this point, aside from UNFCCC action, there was a recent attempt by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)—another fantastic acronym for an appropriately instrumentalist name—to create the world’s largest ocean sanctuary around Antarctica, totaling somewhere between 1.6 and 1.9 million square kilometers.

Unfortunately, Russian and Ukranian representatives questioned the authority of the CCAMLR to declare such a sanctuary, and, in turn, blocked its establishment, undermining what political good will may have existed in this context. Disappointing, to be sure, but in a sense this objection is just a business-as-usual exercise of power given the structure of the Antarctic Treaty System, which—we can only assume is to avoid a sort of Aristotelian tyranny of the majority—demands that international decisions pertaining to Antarctica be made unanimously. So we probably won’t see the creation of an Antarctic Marine Reserve any time soon. While the sanctuary may not have been proposed with specific regard to climate change, it would have been progress regarding Antarctic loss and damage nonetheless. But so much for that.

Sadly, the failed marine reserve also means a failed way to halt whaling in the Southern Ocean. Historically, whaling near Antarctica has been atrocious. In the 20th century, the Soviet Union (among others) was responsible for the disappearance of more than 180,000 whales. 180 thousand. But as of ~27 years ago commercial whaling was declared illegal by the International Whaling Commission (IWC). Don’t be fooled, however, into thinking that the ban put a stop to all whaling. Yes—even in this day and age—there are still whalers out there. What’s even more surprising is that it’s technically  legal. Japan was granted a moratorium from the prohibition in order to do scientific research that involves whaling. Whaling for science! Makes sense, right? Earth First! and Greenpeace eco-activists aren’t the only ones who find this repugnant. Toward protecting against Antarctic biodiversity loss, in 2010 Australia took Japan to court at the Hague—the International Court of Justice (ICJ) in the Netherlands—in order to challenge the validity of Japan’s “scientific research,” which, by Japan’s argument, requires killing whales. Japan has taken more than 10,000 whales from the Southern Ocean since 1988.

The Hague should pass down its judgment within the next few months, so at that point we’ll see what justice holds for whaling. Perhaps on the pessimistic side of legal analysis, by Dr. Rowan Hooper’s reading, the Australian case may be emotionally compelling, but Japan may have a stronger legal argument to uphold their exception from the IWC’s prohibition.

Suffice to say, between climate change, habitat loss, warming water, ocean acidification, and whaling—there are plenty reasons to be concerned about Antarctic loss and damage. The question, then, is what should and what will be done about it moving forward. Let’s get it together humans.

The ethics of rising sea level (I)

Rising sea level: Inevitability and responsibility

The physics of climate change—the greenhouse effect—are well established. As the Sun blasts the Earth with energy, the Earth absorbs some of it and reflects the rest. Then, depending on surface conditions and the composition of the atmosphere, more or less of the reflected energy makes it back out to space. But if the atmosphere gets in that reflected energy’s way because it’s full of carbon, for example, it gets reflected again back down at the Earth. Since much of that energy is heat, global temperatures go up. Just like an enormous greenhouse. Meanwhile, the Sun is still blasting the Earth with energy and the process continues.

The Earth functions much like an organism. Certain homeostatic processes are physiochemically determined. If the system overheats, symptoms start to develop as the system adjusts to stabilize itself. For humans, we might sweat, feel light-headed, lose consciousness, or worse. For the Earth, landscapes change, ecosystems adapt, weather gets more erratic and intense, land ice melts, the oceans expand, and, in turn, sea level rises.

Climate change and sea level rise

Climate change means many things—uncertainty among them—but the relationship between global temperature and sea level is straightforward. When the planet cools, sea level drops, and when it warms, sea level rises. This happens for two reasons: 1) the thermal expansion of water and 2) melting land ice.

The former means that as heat diffuses from the atmosphere into the ocean, the volume of the ocean—the literal space between the water molecules—increases. If that’s not intuitive, think of steam rising from boiling pot of water: if you add enough heat to water, the space between the molecules increases so much that they fly apart and into vapor form.

As for the latter, you can probably guess Antarctica’s role.

As Antarctic temperatures rise, the West Antarctic Ice Sheet will continue to melt, the amount of water in the ocean will increase, and sea level will rise. For obvious reasons, any amount of sea level rise poses problems for coastal communities everywhere.

According to the Potsdam Institute for Climate Impact Research and Proceedings of the National Academy of Sciences (PNAS), we can generally predict 2.3 meters of sea level rise for every °C increase in average global temperatures over the next 2000 years, more than a third of which will be attributable to the melting West Antarctic Ice Sheet. By that math, even if the world manages to keep global warming within 2°C (which is doubtful), we can still expect sea levels to rise by nearly 15 feet.

You can click on the map below and zoom in to see for yourself what the world looks like with 15 feet of sea level rise.

In North America, 15 feet of sea level rise would mean cities like New Orleans, Miami, New York, and Boston are flooded, as are sizeable portion of the Yucatan Peninsula and Alaskan coast. Around the world, Bangladesh and the Maldives, large parts of South East Asia, Northern Europe, much of the Amazon Delta, and the northern coast South America would be underwater.

Though I use hypothetical language, it is important to be clear that some degree of sea level rise is now inevitable. Given present atmospheric carbon dioxide levels, the relevant question is not if sea level will rise, but when, and by how much?

Expectations and inevitabilities

To put expectations in perspective, FEMA’s most recent assessment projects sea level rising by more than a meter by 2100. Miami, the Maldives, the southern tip of Vietnam, swaths of Indonesia, and the mouth of the Amazon Delta are flooded with just one meter of sea level rise.

Here’s a world map of 1 meter of inundation for reference.

And it won’t stop then or there.

Atmospheric CO2 concentrations measured in April 2017 logged around 409ppm (updated May 2017). The last time there was this much carbon in the atmosphere was the Pliocene—3 million years ago. The Pliocene was significantly hotter and sea level was more than 20 meters above what it is today. Given the amount of carbon already in the atmosphere, in coming centuries as the Earth’s natural feedbacks to carbon forcing play out, we are likely justified in anticipating something like Pliocene-era sea levels.

With 20-25 meters of sea level rise, the map looks very different.

Here’s an interactive map tool you can use to check out various amounts of sea level rise.

In the United States, 20 meters of sea level rise means the state of Delaware, California’s bay area all the way to Sacramento, the entire edge of the Gulf Coast (Houston’s port becomes the coast and much of Louisiana goes the way of Atlantis), and the bottom third of the Florida Peninsula are all underwater. Elsewhere in the world: Shanghai, Bangladesh and the Maldives are long since submerged.

But it could be much worse depending on how global climate policy evolves and how the West Antarctic Ice Sheet and other stocks of land ice respond to climate change.

Catastrophic sea level rise

For sake of thought experiment, let’s consider the catastrophic scenarios projected by the IPCC’s A2 and A1F1 emissions pathways, putting us somewhere between 800 and 1000ppm CO2 by 2100. These worst-case scenarios mean that eventually, as Earth systems respond over centuries to come, we reach Eocene conditions—a world entirely without ice. Without ice anywhere on Earth, sea level sat more than 100 meters higher than today. The map tool only displays up to 60 meters of sea level rise, but that should be motivating enough. Just consider it a conservative portrayal of Eocene-era sea levels. BuzzFeed also recently issued some interesting depictions of what the world looks like without ice.

There are good reasons to think that this is bad, or at least undesirable, in and of itself. Maybe we want land ice to exist for its own sake. It might just make us feel better to know that glaciers are out there. Moreover, perhaps we have an obligation not to destroy the natural condition and function of the Antarctic ecosystem, even if not for the ecosystem’s sake but out of respect for Antarctica inhabitants’ right to habitat.

Relevant concerns, to be sure. But the human implications of catastrophic sea level rise are more than disturbing enough to warrant the catastrophic hypothetical. With Eocene era sea levels, cities flood the world over, many coastal countries are submerged entirely, and hundreds of millions of people lose their homes.

In the United States, the Gulf and Southeast Coasts are fundamentally reshaped. Florida is completely submerged, the Mississippi Delta consumes all of Louisiana and extends into northern Arkansas and Tennessee, and Georgia and South Carolina lose large stretches of eastern territory. Bangladesh and much of India, vast amounts of Northeastern China, Indonesia, Malaysia, Vietnam, the Philippines, all of Denmark and the Netherlands, as well as much of Northern Germany including Berlin are entirely flooded.

Some nations like the US and China have large amounts of inland territory into which their populations can move (albeit still at huge costs), but many do not. Many people, Bangladeshis for example, will lose their entire country in the catastrophic scenario. This raises several questions.

Where should people of entirely submerged nations go? How should responsibility for adaptation assistance be divided? Should neighboring nations take on climate refugees simply because they’re closer, or should nations with greater contributions to climate change or greater ability to pay shoulder more of the responsibility?

The forced migration of countless individuals to new regions within and without their own nations—i.e. population displacement—is perhaps the most obvious ethical dilemma presented by the catastrophic scenario. Bangladesh is commonly considered with regard to the catastrophic sea level rise and population displacement because it is densely populated and especially vulnerable to rising sea level.

Moreover, Bangladesh’s cumulative and annual contributions to climate change inducing greenhouse gases are negligible. Compared to the United States, Europe, India, and China, Bangladesh is not, in large part, complicit in causing climate change, the melting of land ice, or the rise of sea level. That Bangladesh bears little responsibility for causing climate change and its impacts on sea level, yet shoulders the most extreme conceivable consequence is intuitively objectionable by most common conceptions of justice, wrongdoing, rights, and fairness. And if we were to weigh the marginal benefits of industrialization against the resulting change in climate and sea level rise, it would be a strange calculus indeed that rules the prerogative to continue burning fossil fuels over and above the global costs of lost coastal territory and massive population displacement.

Our new hydroverlords

The image below is one of four precipitation models published by the National Center for Atmospheric Research (NCAR) that together forecast extreme global drought less than 50 years from now as a consequence of climate change. What follows illustrates predicted global precipitation levels in 2060-2069 assuming a moderate greenhouse gas emissions scenario as defined by the International Panel on Climate Change. Moderate.

Climate prediction map 2060-2069

Precipitation Model with Climate Change: 2060-2069

Take a moment to let all the purple, red, and yellow sink in. These are Dust Bowl conditions and worse. Take another moment.

It is difficult to emphasize enough the gravity of this predicted drought. We should all keep the above image in mind when we consider the value of water. Water is fundamental to the existence of life as we know it. Not just human beings. All life on Earth. For obvious utilitarian and deontological reasons, by the land ethic and the difference principle, by the precautionary and proactionary principles, and by our natural moral sense, water is of the highest non-arbitrary value and it is our responsibility as constituents of the human world and of the Earth itself—if we even entertain such a distinction—to do everything in our power to prevent and prepare for this possibility.

Pause to consider what it would mean for governance, for geopolitics, for the world if we fail to curb climate change beyond this moderate GHG emissions path and simultaneously 1) fail to implement and enforce the universal human right to water as recognized by 122 countries of the UN in 2010, and/or 2) consent to the privatization of water resources by multi-national corporations. I, for one, would not welcome our new hydroverlords.

What’s worse, the map shown above is only the third of four models. The fourth model extends from 2090-2099. Brace yourself for the purple: Precipitation Model with Climate Change: 2090-2099

Water resource management, conservation, and preservation will likely fall into their own compartmentalized regime complexes—as discussed by Keohane and Victor—fragmented from other initiatives focused on mitigating and adapting to the various impacts of climate change. According to Keohane and Victor, there’s reason to be optimistic about the capacities of this regime structure. But simply adapting to new conditions of water scarcity equates to treating the symptom rather than the disease. While adaptation is absolutely necessary, we must simultaneously confront climate change at its source: human greenhouse gas emissions (carbon dioxide, methane, nitrous oxide, etc.) and the several positive feedback cycles that global warming entails.

Atmospheric carbon dioxide concentrations alone are currently around 397 parts per million (ppm), which essentially guarantees an increase in average global temperatures of ~4 degrees Fahrenheit (~2 degrees Celsius). What’s more, unless we reduce GHG emissions by ~80%, we can expect the increase in average global temperature to be even more dramatic.

Confronting climate change means one of two things (and maybe both, but probably not—the former would render the latter largely unnecessary and the latter would likely preclude the former). We must reduce greenhouse gas emissions through 1) an immediate significant reduction in energy consumption or 2) a techno-scientific revolution in renewable energy, energy storage, energy transmission, transportation, agriculture, infrastructure, manufacturing, and architecture.

Coupling either approach with reforestation and afforestation projects would be a good idea too, especially considering the Brazilian government’s recent report that deforestation in the Amazon has actually gotten worse since May of 2012.

In all likelihood, the future holds an increase in energy consumption, not a decrease, so we must—at some level—prepare ourselves to rely on faith in Julian Simon’s infinite resource of the human mind to spark the large-scale techno-scientific advances that the climatic consequences of our industrial behavior demand. We must have faith in progress, despite the paradox therein. A daunting task, to be sure, but we have little choice as we have collectively agreed, both implicitly and explicitly, that the Good Life is an energy intensive one. The climate challenge is upon us. If we are to progress, we must progress toward sustainability—and hopefully to a future with more water than NCAR has predicted. Let’s get it together, humans.
