Arkansas: Awaiting a Wave

It has been a while since my last post, a lovely coincidence perhaps to Cupid's arrow and new family with a fellow blogger! 💘

Keeping true to this blog's goal to bring more indigenous Marshallese voices to the dialog surrounding climate change, here is---in my humble opinion---the most well done and certainly most artistic piece of the past year.

Awaiting a Wavecomes from THE WEATHER CHANNEL United State of Climate Change Series, which aims to share "a climate story for every state in the nation." This particular story belongs to the State of Arkansas and features "individuals, communities and businesses responding to the changes that are already happening in America, and how they’re preparing for the changes that have yet to occur." Quoted text from http://features.weather.com/us-climate-change/about/. Some of those individuals include:

Tidying up a bit

Last year I saw an article in Science magazine that combines various statements from researchers in a way that "substantiates" the author's message that the climate change prognosis for atolls is perhaps not as bad as people living on atolls such as Kathy Jetnil-Kijiner and Ministry Tony deBrum have made it out to be. The debate has come up several more times in the media, and thus is worth further examination.

The author quotes Dr. Paul Kench of the University of Auckland as having stated that based on data from Jabat Island in the Marshall Islands, coral growth of 10-15mm per year will exceed the rate of sea level rise, thus allowing islands to grow and remain above water. Although this may indeed be the case--that the islands will remain above water--consider for a second how long it would take for 1) coral to grow, 2) be broken up and thrown onto intertidal reefs by waves and currents along with finer sediments, 3) and then for plants to take root and "cement" all these atoll building blocks together, and 4) finally for organic matter to decompose and provide a truly habitable environment for humans to survive. Atolls that are only allowed to build naturally up to the first step mentioned above, before having to build up yet again to keep pace with sea level rise, would not be fit for habitation without significant environmental engineering contributions.

I asked another atoll researcher named Dr. William Dickinson about it, and his take was that "The Kench study of Jabat shows nicely that islands could form near the highstand where buildup of rubbly storm ramparts on reef flats was sufficient (how that eventuality might or might not influence human settlement seems an open question to me, as such places would not be very attractive for habitation)."

An Introduction to Atoll Geography


The following is an excerpt from an unpublished thesis paper on “Atoll Habitability Thresholds” by M. Stege, Columbia University M.A. in Climate and Society Program Class of 2014. Above image courtesy Schmidt 2010.

An atoll is a ring of reef surrounding a central lagoon. There are often islands or sand cays interspersed within the reef.  Sand cays and vegetated islets are all that remain visible above water level during high, tide, and represent the only potentially habitable areas on an atoll. It was Charles Darwin who, while observing these unique landforms near the western coast of South America, first theorized how tiny polyps could form barrier reefs grown atop subsiding volcanic edifices (Darwin 1842: 109). Since then reef core and radiocarbon evidence from multiple atoll sites have confirmed Darwin’s theory, and expanded on the important role that sea-level fluctuations due to tectonic- and glacial-controlled forces have played in reef development. (Woodroffe and Webber 2014: 193) In other words, atolls are barrier reefs grown atop both subsiding volcanic edifices dating back tens of millions of years and episodic coral reef growth and discontinuity relative to sea level along millennial timescales. Note that This discussion of atolls does not address the handful of ‘emergent atolls’ and islands that have been lifted above sea level by tectonic forces. Only ‘subsiding atolls’ are discussed.

The last episode of coral reef growth and discontinuity (Figure 3, inset B) is uniformly evidenced among atolls starting around 8,000-10,000 BP with the inundation and submergence of present day atoll platforms due to sea level rise during the Last Interglacial. Coral growth appears to have lagged behind rising sea level during this time, until eustatic sea level stabilized at the ‘mid-Holocene highstand’ around 5,000-6,000 BP (Woodroffe and Webber 2014: 241-243). A period of explosive ‘catch up’ growth followed, during which different reef structures ‘caught up’ to sea level at different times and where margins of the atoll more exposed to wind-driven seawater nutrients generally grew fastest. Sea levels remained stable at the mid-Holocene highstand between 3,000-5,000 BP, a period marked in atolls today by the development of conglomerate platforms which formed after vigorous reef growth had ceased and lateral reef consolidation flourished. (Dickinson 2009: 4-8) These conglomerate platforms are the fossilization of reef, sediment, and boulder deposits, all cemented together to form a durable bedrock on which many of an atoll’s sand cays and islets are today “pinned.” (Dickinson 2009: 7) Excluding major storms these foundations make those pinned atolls resistant to wave damage, and therefore stable over the last few thousand years. As would be expected, these pinned islands are consistently most prevalent on the windward margins of an individual atoll. In lieu of projected sea level rise, Dickinson refers to ‘crossover dates’ when these conglomerate platforms start to become largely awash, as they were during the mid-Holocene highstand.

Looking towards the future, these conglomerate foundations that underpin the stable Pacific atolls are predicted to be become largely swept away by rising seas at some ‘crossover’ point, leading to the atolls being vulnerable to fair-weather wave attack. (Dickinson 2009: 7) When these crossover points occur, atoll erosion processes will become greatly accelerated, signaling a return to the atoll’s previously submerged and uninhabitable state a number of millennia ago. It is worth noting that around 2,000-3,000 BP a gradual ‘post-mid-Holocene sea level decline’ of about 0.8 meters occurred This was caused by oceanic siphoning wherein seawater was required to infill collapsed submarine arches and deepening continental shelves created by geological glacial mass loss (Miltrovica and Peltier 1991, 2002). Near consensus within the scientific community further holds with “very high confidence” that by the end of this century global sea levels will have risen by at least the observed global average since 1900 of about 0.24 meters plus ocean thermal expansion so closer to 0.62 meters (IPCC 2013). This is a conservative estimate of sea level rise which excludes escalations from glacial and ice sheet melt, which would raise the estimate to 1.2 meters (IPCC 2013), and even higher beyond the 21st century. (Joughin et al 2014, Rignot et al 2014) All this on top of several meters of natural sea level variability due to fair-weather ocean dynamics leaves little doubt that coral atolls will ultimately become uninhabitable due to sea level rise.

These “irrefutable, as well as shocking” realities of climate change, as pronounced by US Secretary of State John Kerry in his address to the 2013 Pacific Islands Forum, necessitate a coordinated and scalable response.

What Makes a Place Habitable? Or Livable?

That was the title of a short article I prepared for the M.A. in Climate & Society Program "Hot Topics" page.  Thank you to Brian Kahn, Wed Editor at Climate Central (and C+S alum) for his fine editing assistance.

Atoll Habitability Thresholds

Its been four months since returning home from the Columbia M.A. in Climate and Society Program, and I am now doing field work to refine my thesis paper on atoll habitability thresholds with intentions to submit to my amazing team of advisors Michael Gerrard and Benjamin Orlove, PhD by July of this year. Wish me luck!

So some people have been asking what is this "habitability thresholds" thing? Well, the basic idea is that as ecosystems that make up areas of the world that different societies inhabit (e.g. atoll ecosystems for Marshallese) incrementally undergo physical and chemical changes due to climate change, the habitability of these ecosystems will incrementally diminish as well. Monitoring these changes and positively affecting their longevity is at the core of this idea.

One of the things I like about it so much is that it is very human focused, and reflects what society determines as acceptable. It is intentionally oriented to allow everyday citizens the opportunity to organize themselves around the process of understanding how climate change affects their lives and ecosystems, and then to act on that information. I believe that potential climate-displaced communities can be empowered in spite of the disempowering phenomena of climate change, and I believe it can be done by framing climate impacts, adaptation, and resilience around internationally recognized, locally refined, concrete measurements of habitability.

It is going to be a wonderful journey of discovery into climate science communication, and I am encouraging people with an interest to delve more into the concept and its demonstration in other settings (e.g. mountainous community settings in Nepal) as well.

    Facing a grim reality with confidence and not with despair

    Also available here

    Marshallese are the descendants of seafarers who seized the climatic opportunity some 2000 years ago–when sea levels dipped to present position–to entrench a civilization with distinct customs and life skills suited for human habitation in what is now called the Republic of the Marshal Islands (RMI). Looking towards the future with 0.6 – 1.2 meters of sea level rise projected by the Intergovernmental Panel on Climate Change by the end of this century, Marshallese face increasingly frequent threats of submergence, coastal flooding, and coastal erosion that will progressively render atoll environments uninhabitable.

    This grim reality is quietly but notably alluded to in the United States 3rd National Climate Assessment released last May. It comes in the assessment’s 23rd chapter, in the form of a ‘key message’ to the 100,000 or so atoll inhabitants within the US-affiliated Pacific islands region. As foretold: Mounting threats to food and water security, infrastructure, and public health and safety are expected to lead to increasing human migration from low to high elevation islands and continental sites.

    Work is now underway to better understand and anticipate the timing and spatial sequence of climate-induced migration, particularly given the exacerbating impacts of tropical cyclones and drought. This type of information will help not only Marshallese prepare for climate change, but also the host communities that are likeliest to receive them as climate migrants, so that collectively we can confront the tides of climate change with confidence and not with despair.

    Homeowners Guides, Landowners Guides, and Atoll-Wide Frameworks, oh my!

    Came across a 1990s Marshallese homeowners guide for new buildings to strengthen against wind damage during tropical cyclones. Maybe old news, but new to me! It is written in Marshallese with FEMA funding and Office of the Chief Secretary support. From what I can tell it covers wood framed buildings, emphasizes brackets at all joints, and use of high quality nailing work especially with aluminum sheeting.

    It reminded me of a hazards community guide in development, courtesy of UH Sea Grant Program that "will cover specific topic areas, such as how to protect oneself in an emergency through disaster preparedness (i.e., evacuation planning and maintaining emergency supply kits), guidelines for identifying and mobilizing local assets, and best practices for developing ‘adaptation coalitions’ to facilitate locally-led, long-term, and flexible strategies for community resilience." Stay tuned!

    This hazards community guide in turn also reminded me of the Landowners Shoreline Protection Guide released in 2013. It was prepared by UH Sea Grant with USAID/NOAA funding, and I think UNDP/OEPPC supported with funds as well. This Landowners Guide was largely translated by CMI Land Grant Program and at Marshallese Language Commission, and reformatted as a oral slideshow. The presentation was then tested in August 2013 by Karl with translation and logistical support by the Djarrot community resource management committee, and later presented to the Mayors Association in November 2013. 


    And of course, to complete the circle of reminders, these self-help guides reminded me of another guide available to Marshallese seeking to build their resilience to climate impacts. It is the Reimaanlok Framework released in 2008. This guide targets municipal governments rather than homeowners/communities, and is accompanied by financing support, which all means that it requires facilitators to help implement.

    So from the 1990s to the present day, some good guides and in culturally-sensitive formats people can absorb, kommol nan ro raar kobooj melele rot kein elap aer jiban armej in Majol. It would be great to see all these existing resources downloaded and shared widely, and even greater if presented orally (i.e. bwebwenato) via one-on-one or group discussions.

    "...our island is who we are."

    September 25, 2013 @ Columbia University in New York City

    "In ways that the English language can not fully convey, our island is who we are. It is not just our culture, but our personal identity."
    - His Excellency Christopher Jorebon Loeak, President of the Republic of the Marshall Islands

    "[Migration] is an admittance of defeat, before we are actually defeated... To move us from our home is tantamount to asking us to eliminate a society from the face of the Earth. We're talking about the elimination of language, a way of life..."
    - Honorable Tony deBrum, Minister-in-Assistance of the Republic of the Marshall Islands




    Intro to 2014

    It is 2014, nearly 1 year after my last post. What a difference a year can make!

    I am grateful for the opportunity to study this year with top climate researchers at Columbia University. Among many things, this is an opportunity to visit our embassy at the U.N. Mission and I look forward to that especially. Meanwhile, H.E. President Christopher J. Loeak and his delegation have already made their mark in the Big Apple... the subject of my next post.

    Case study of Rita Reimaanlok

    Western representations of "disappearing island nations" are often characterized by unhelpful alarmism and assumptions of inevitable resettlement. In recent years, climate vulnerability researchers in the Marshall Islands have devised communication strategies that present their findings while avoiding the negative connotations. In the community of Rita the residents have enacted an ambitious climate change resilience program to demonstrate the necessity and feasibility of culturally sensitive, community-based approaches to meeting the environmental challenges of the 21st century.

    Integrating Climate Science into Marshallese Language Arts


    After two semesters with 9th grader at Marshall Islands High School, a clearer understanding of the interconnectedness of culture and science emerged, as shown in the Ae-Lon-Kein (Ocean-Sky-Land) diagram above. It was amazing watching the students' eyes light up and remain engaged (for the most part, when they weren't busy being teenagers!! :) 

    To my 9D group from Spring 2011 and Fall 2012, see you around scientists!

    And kommol to Aenet Rowa for putting this article on his immensely helpful website Yokwe.net.

    H2S Test, Measure Tank, and Treat Water



    This photo show two groups of students, all in the 9th grade, trying to determine the volume (by cubic feet) and content of water tanks on campus. They later converted to gallons in the classroom, thereby determining how much Clorox to mix into a contaminated tank.

    The lab is part of the pilot curriculum for Science and Marshallese Language Arts being developed at the Marshall Islands High School. The curriculum has, among other things, contributed to the supply of (previously unavailable) safe drinking water on campus.

    It hit home on Earth Day 2012

    The article below appeared in edited form in the Huffington Post for Earth Day 2012. Kommol tata to Brook Meakins for making it possible.


    When it hits home...
    By Mark Stege

    Around ten thousand years ago, while a group of 29 high volcanic islands crumbled back below the surface of the Central Pacific Ocean, tiny polyps banded together to form massive coral reef colonies, today known as the coral atoll nation of the Marshall Islands. 

    My parents kept a small retail store on one of the 29 atolls when I was very young, and from breakfast to dinner without stopping for lunch, I would swim and play with my cousins on the old bullet-ridden Japanese pier, beside manta rays jumping clear out of the water and Taroa, Maloelap’s signature Terushima Maru listing to port. I still remember falling to sleep imagining that sunken WWII freighter guiding itself closer to dock.

    Last week, after sixteen years away, I returned to my childhood playground, normally about 25 minutes by plane but this time 14 hours by boat. I plan to make at least two more trips this year, largely because the people who live there have given me a tremendous gift by electing me to represent them on the Maloelap Atoll Local Council. The first trip will be to collect different varieties of pandanus seedlings to plant on the urbanized capital atoll of Majuro, 100 miles south of Taroa. The pandanus is a deep-rooted tree with nourishing fruit, and is part of our limited arsenal to preserve both culture and coastline.

    You see, the earth’s climate is warming, causing incremental increases in sea level sufficient enough for some of my Marshallese friends to liken today’s warning of sea level rise to God’s warning for Moses to “make thee an ark of gopher wood.” As a result, Moses was prepared when sea levels shot up within 40 days and 40 nights. Will there even be a Majuro or a Taroa to speak of in 40 years?

    Both my homes are now disappearing. Last week on Taroa, I saw the beaches have begun to creep inland, particularly during king tides. Coconut trees have fallen sideways, and even the Y-shaped pandanus branches now lean seaward, the sandy soil beneath inundated by the expanding ocean.

    Climate change has become an all too familiar term for me these past several years. It has altered certain parameters of my imagination, introduced others, even put human existence into perspective. A recent visitor, an oceanographer from the University of Washington who has been studying climatology for the past two decades, told me climate change hit home for him when his airplane touched down on Majuro. Even after an entire term studying and preparing for his upcoming expedition to a place that sits just a foot above high tide, it only struck him how vulnerable places like Taroa actually are upon seeing up close these atolls for the first time. “Are you familiar with the term ‘a canary in a coal mine’?” he asked. All too familiar, I thought.

    Thinking of it now, I’m transported back to one youthful day on the Japanese pier on Taroa, when pink and orange clouds bedazzled the horizon. A few of us still remained after another full day swimming alongside manta rays, reluctant to go home. I sat transfixed by the fleeting sun, when a bright green flash of light suddenly burst out just as the sun sank below the waves. I was unsure of how refracted light could emit green amongst such different colors as orange and pink. I’ve only seen the green flash that one time, so I know it is rare.

    It may be too late for the people of Taroa to hold back inundation, storm surges, erosion and other natural processes that are now amplified by climate change. But for now, the way I see it, climate change for Taroa will boil down to ensuring healthier coastlines, more sustainable methods of existence, and preparing our children to articulate their own imperiled future on or off these fragile islands.

    I’m reminded of plans raised last week on Tarao to establish a community-based Marine Protected Area, specifically to protect a school of mackeral there that traditionally could only be harvested by scooping them out of the water with a special basket made from pandanus roots. Legend has it this school is magical and will never be depleted. It is of little interest to a burgeoning sea cucumber and reef fish trade now under the Marshall Islands government’s oversight, so potentially a good foot in the door for bigger MPA regulations down the road.

    My thoughts turn next to how we might possibly convert our sea transport services to wind-and-solar-powered vessels; and how the women who serenaded me as their prodigal son last week requested bicycles for hauling their goods, knowledge to combat an invasive pest that threatens their food supply, and a market for their exquisite woven handicrafts. I think of the teachers’ request at Taroa Elementary School’s for a 2-year substitute teacher so that they may take the time to finish their degrees in education on Majuro.

    I think of all these things, and how they all add up to the enormous amount of work we must do, both because of and irrespective of climate change – us on Taroa, the 53,000 others in the Marshall Islands, and the billions with whom we share this earth. There is so much work to do together. I think again of the old bullet-ridden pier, the green flash of my youth. Somehow, I know it will always be within my people’s sight, and our home will not stay gone forever, but someday rise again, polyp by tiny polyp, for the manta ray to play once again.

    Jerammon Namdrik Atoll im Mr. Mayor!


    Mayor Clarence Luther’s commitment to his fellow islanders is clear: “When I heard about climate change and seal level rise – I was really scared – I thought it was going to happen tomorrow. And now I realize we can do something and we have some hope. If we don’t do what we are doing it takes your power away and you don’t know what to expect. We can do something to make our lives better for now and the future. We can show that we can do something and that we can survive years from now but if we don’t do something we are not going to survive for long. This way we have a lot of lessons to show other parts of Micronesia and Melanesia. We want to get our lessons to other places.”

    Kommool tata (thank you so much), Carteret Islanders

    Yesterday I came upon this inspiring feature on the United Nations University website.

    I was particularly drawn to the the idea of making sustainable use of the ancestral marine resources long after relocation: “In the future, we will keep coming to these reefs and manage them as our fishing ground,” explains community youth leader Nicholas Hakata. “When our children come back, they will have a connection to their heritage.”

    Kommool tata, thank you so much, Carteret Islanders. Jerammon nan kom. Peace be with you.
