Seoul Snapshots: Yangjaecheon, Cheonggyecheon and Hangang

Hello everyone :) I wanted to tell you that this is the last blog post for EcoHeal. In a few weeks, I will be flying to University of California, Berkeley for my higher education. Realizing that it would not be possible to regularly update a blog dedicated to Seoul from the United States, I made the decision to conclude it with a rather "special" post themed around the waters of the city. You will find below pictures of Yangjaecheon, Cheonggyecheon and the Han River (Hangang) along with my reflections on natural and built environments of the water bodies.  Those of you who have been following EcoHeal would know that Yangjaecheon has been a hugely important focus of my blog; I felt that updates on the stream would be a necessary element for this blog's finale. :) As for Cheonggyecheon and the Han River, I had the chance to visit both in recent months and wished to share what I felt with you. I truly appreciate your encouragement during the last two years, and I hope you enjoy the photos below. Thank you <3

A drive between Gangnam and Gangbuk captures this scene. Hangang is vast: as you can see from the map below, the river runs through the entire city. In fact, as the fourth longest in the country, it flows through Gangwon, Chungbuk and Gyeonggi regions as well. 


The Han River flows from the mountains out to the Yellow Sea.
As the fourth longest in the country it runs through the entire city. 


 The on-going construction of Lotte World Tower
- something I personally don't feel certain about (End of April '15)
What I love about the river is its series of twenty-seven bridges that span throughout within the city limits. I've heard some say that having such a river dividing Seoul into north (Gangbuk) and south (Gangnam) engenders conflicting disparities in the city. In my perhaps naive and inexperienced eyes, however, this landscape is an element that truly belongs. Seoul has gone through incredible changes during the past decades - from the deconstruction of city walls under the Japanese occupation to the development of foreign architects' futuristic designs of public spaces among traditional markets (read a previous post on the Dongdaemun Design Plaza here). As a natural landmark, Hangang has remained. It has been the foundation of cultural development from the Neolithic Age and the center of politics and economy ever since the capital city was set in the area. A unique architectural panorama of different bridges was a natural reaction to foster the communication and transportation between the two parts of Seoul. This view holds a special place inside me; it was during a drive at dawn along Hangang against the city skyline that I realized I had come to truly love my city.


 You can find yourself under the bridges when you head out from the Seoul Forest on your bicycle :)


 Both Yangjaecheon and Cheonggyecheon are sub-tributaries of the Han River. The former leads from Tancheon and the latter form Jungnangcheon. Yangjaecheon and Cheonggyecheon are both regarded as successful environmental recoveries. As I explained in a post last year, the former was recovered to its current state through a restoration project. Whenever I stroll along the wild grasses by the stream, I am filled with utter gratitude. The ecological park of Yangjaecheon feels natural and free. Instead of manicured lawns and kitschy benches with a glossy veneer, we have chest-high porcupine grass and wooden fences with an age-worn familiarity. 


 The familiar scene of Yangjaecheon

 The sky shimmered that day.






Cheonggyecheon, on the other hand, usually gives very different vibes. Located in one of the busiest areas of Seoul, it is surrounded by commercial offices and rows of little shops. It is a busy destination popular with couples and tourists, but a late afternoon walk on a weekday can be very peaceful.

- my favorite time to visit Cheonggyecheon

Leading to the Pyounghwa Market




Just like Yangjaecheon, a significant part of flora and fauna returned to Cheonggyecheon after the recovery project and I couldn't be happier about this. Still, it bothers me that the restoration process was much too hurried; it was initiated in 2003 and opened to the public in 2005. Although indiscernible under an unknowing gaze, the water flow is not natural but pumped artificially from below the concrete base, requiring an incredible amount of energy. It remains that Cheonggyecheon has not been truly "recovered". I hope to be able to find a solution for this problem with the wisdom I will grow from studying engineering and environmental design at Berkeley.



Again, thank you for following EcoHeal during the last two years. I feel blessed to have been able to share with you some snapshots from my highschool years in Seoul. If I begin a new blog - perhaps about my new environment in Berkeley - I will make sure to leave a short post here to inform you. Love, Jaewon

Quick Updates: The Late Spring Scene at Yangjaecheon

Hello everyone! I just wanted to give you some updates on our beloved stream.  :) The pearly glow of cherry blossoms is gone now and the quiet, misty green has settled again. Lately, I have been doing some runs along Yangjaecheon as the first activity of the day, so the pictures below were all taken in the early morning. Hope you enjoy :)


A rustic calmness that is the beauty of Yangjaecheon -
a remarkable gem beside the sprawling towers of Gangnam
This layout reminds me of the adorable trolls from Frozen! ;) 
Believe it or not, it was the first time I saw a snail at Yangjaecheon.

Cherry Blossoms of Yangjaecheon

Cherry Blossoms are in full bloom at Yangjaecheon.  It's almost as though I've never seen the stream before. Their scattered petals flutter together in the air, traveling along the water. Perhaps a little strangely, I'm reminded of the ending scene of a childhood favorite - leaves of coral orange and magenta rippling to John Smith from Pocahontas. A truly magical quality in the air.

"Spring is Here!" from Yangjaecheon...with its own Emerald City? :)

I've taken to running along the stream lately. I figured it was time for some more serious aerobic exercise. ;) I have to admit that the lingering frosty wind sometimes slaps my hair across my face (quite fiercely), but I don't mind when I have the spring sunshine bouncing off my shoulders! Here are some pictures I've taken over the past few days. Hope you enjoy :D


Wizard of Oz, anyone?
The blue of the glass on the building surfaces sometimes flash shades of green
 - dark turquoise, chartreuse, lime. We even have our own yellow brick road
I guess we have a view of another Emerald City ;)


Shimmering ripples on the concrete
Fuzzy lilliputian puffs of porcupine grass!

Skeptics and Deniers: The Conclusion (Part II)

Part of the previous blog post: 
This post is Part I of the conclusion to Skeptics and Deniers, a series of analyses on the book Unstoppable Global Warming: Every 1,500 Years by Fred Singer and Dennis Avery. I'm sorry about the delay in publishing this post :( I really wanted to give a more in-depth review of the book, and the writing became too long to be a single post. That's why I divided it into two parts! Please understand that it took longer to explain my judgments, inferences and opinions in greater detail for a comprehensive review. 

* For those of you who haven't been following these posts, here is a little background information:  the book's  authors assert that Global Warming is simply part of a succession of changes in the Earth's system; there is only weak evidence that Global Warming is anthropogenic; Global Warming might actually be beneficial; we do not have to make an effort to curb CO2 levels, because they aren't responsible for Global Warming.  If you wish to see my analyses posted over the past several months, please check out the previous blog posts: on the Earth and the Sunthe weaknesses of the Greenhouse Theory; Rising Sea LevelsMass Extinction Part I, and Mass Extinction Part II



We've finally reached the end of the book. Looking back at the previous posts of this series, I see so many topics and sub-topics that the authors explored to explain their views. Methods of scientific research, inferences made from statistics, connections between health and climate change, possible misconceptions of the public, the role of politics in influencing mass media, the evolution of foreign policies and protocols, etc. Along with this, the authors present a rather detailed overview of the history of climate change that took place on our Earth. I deeply appreciated this part of the book, in that it gave me a chance to truly reflect on my own views, knowledge and ways of accepting new findings and research.


I also became aware of the limited scope of my understanding of our world. Frequently, when the authors stated the flaws and inaccuracy in research that presented ideas I saw as "facts" e.g., 'Global Warming causes extinction of many species', I couldn't decide which side to lean towards. Should I stick with what I've internalized throughout my entire education so far? Or would it be ignorant to dismiss these new ideas as absurd? The main reason for my indecisiveness was my lack of knowledge of the scientific, social, and political spheres of our world

This leads me to another question: how confident are the authors in their own beliefs and ideas? While I was thankful for the aforementioned experience I received from this book, I was puzzled, bewildered, astonished, even incredulous at the way they laid out their information. I cannot possibly list all, but there were so many generalizations, exaggerations, manipulations of words that were used to support their views. A seemingly innocuous sentence such as 'People choose land with higher productivity for agriculture, which inhabits less species, leaving our the rest of the world's land to nature.' At first glance, this single sentence doesn't seem out of the ordinary. However, when looked at just a little more carefully, it is outright wrong. It almost makes it seem as though we only use land for agriculture. We use land left over from agriculture for so many other purposes, such as shelter, transportation, goods production, etc. When sentences like this are scattered around the book, a quick reader would gain the misleading impression that we humans aren't powerful enough to impose great changes in our environment.Why would the authors write such sentences? It certainly helps their opinion that humans aren't really causing so much change on our planet (ex. not causing Global Warming, not driving wild species to extinction). With this realization that I began to see the book as somewhat manipulative. Along with this lingering idea, it was when I noticed other aspects of the book that I began to doubt the credibility of the authors.



I hope I have given you at least a glance at climate skepticism. I realize that I may have been partial to my own beliefs at certain points; I know, however, that I put a lot of effort into presenting an objective view and leaving some points to be interpreted by the readers of my blog. Whatever view an individual has, it is always helpful to be aware of the entire spectrum of viewpoints, as well as the logic and evidence behind them. This may be the only way we can become more certain that decisions we make in our endeavors are not illogical or unfounded but reasonable and substantiated. I hope you have enjoyed this series of blog posts and will begin to explore more on how our planet really works. I will do the same when I go to college and explore to address the questions that I have.

Thank you for supporting me, and I will see you in March!

Skeptics and Deniers: The Conclusion (Part I)

This post is Part I of the conclusion to Skeptics and Deniers, a series of analyses on the book Unstoppable Global Warming: Every 1,500 Years by Fred Singer and Dennis Avery. I'm sorry about the delay in publishing this post :( I really wanted to give a more in-depth review of the book, and the writing became too long to be a single post. That's why I divided it into two parts! Please understand that it took longer to explain my judgments, inferences and opinions in greater detail for a comprehensive commentary. 

*I added pictures of some pages in the book. As I mentioned before, I had to do with a Korean translation of the book that I found in the library. So don't be surprised when you see just Korean letters! I put them up for the Korean followers of my blog :) 

* For those of you who haven't been following these posts, here is a little background information:  the book's  authors assert that Global Warming is simply part of a succession of changes in the Earth's system; there is only weak evidence that Global Warming is anthropogenic; Global Warming might actually be beneficial; we do not have to make an effort to curb CO2 levels, because they aren't responsible for Global Warming.  If you wish to see my analyses posted over the past several months, please check out the previous blog posts: on the Earth and the Sun; the weaknesses of the Greenhouse Theory; rising sea levels; Mass Extinction Part I, and Mass Extinction Part II


My blog posts have been mostly covering the earlier part of the book, up to the relationship between Global Warming and Mass Extinction in Chapter 6. The following are some of the points that the authors make throughout the rest of the book, not just in the final chapter :) I also added my comments for some of them. Again, please remember that the words highlighted in pink are those of the authors.


Chapter 7
aaa: During the Medieval Warm Period, the population of Europe grew by 50%. It can be inferred that there was much greater food production during that time. Wealth of food brought prosperity to the cities, transportation and construction.

Chapter 10
aaaGlobal Warming does not bring about greater frequency or strength of droughts, hurricanes, storms and tornadoes. For example, WASA (Waves and Storms in the North Atlantic) found there was no evidence warmer climates in 1900 - 2000 resulted in more storms or hurricanes. 


Chapter 14

aaa: There is strong evidence that abnormally low temperatures bring about greater casualties than abnormally high temperatures. Besides, the growing popularity of air conditioning will make illnesses and deaths from heat less likely. (According to a research in the early 1980s, the number of deaths during abnormally hot climates was 41% less in households with air conditioning than those without it.) Additionally, cardiovascular diseases and respiratory diseases can become much worse in cold climates. 
    : I understand that the authors are trying to emphasize how warmer temperatures aren't the worst. Colder temperatures can be worse in many ways. But is the comparison between the hot and cold really appropriate in this book? All abnormal climate phenomena can be disastrous. We're trying to figure out the best way to handle the changes in climate that are occurring in the present moment in time. Does it really matter whether the current climate is not as catastrophic as another?


Chapter 15
aaa: The rich do not necessarily have to reduce their levels of consumption. They tend to have fewer children, need less land, reduce levels of environmental pollution that result from industrialization, plant many more trees, provide most of the funding for nature conservation. Wealthy nations are taking a positive role towards environmental conservation, not that of destroying the Earth. People of the ancient ages didn't 'live in harmony' as we believe them to have been; they actually damaged nature because members of their tribes always exceeded the absolute limit of their resources. Supporters of the Green Revolution, a central idea of which is that developed nations must reduce their consumption, should consider the way such a 'simpler lifestyle' would influence life span and quality of life.
      : Such unconventional ideas and generalizations are pretty common in the book. Still, I was taken aback at the way the authors presented their ideas. What do they mean by "need less land"? Is this logic formed on the basis of "less people, less land"? What about the amount of food they require per person and the spacious homes they inhabit, both of which need land? Even if they themselves physically take up less space, much land is required to provide the products and resources that they consume. Simply emphasizing the wealthy's potential in helping nature conservation isn't really appropriate here when we're dealing with statistics like the following: USA, less than 5% of the world's population, took up 18% of the world total primary energy consumption in 2012 (US Energy Information Administration). 


    : Hypercars that run on hydrogen (see the Wikipedia page on Hypercars here)are claimed by some (which include the famous Jeremy Rifkin, author of Entropy) as a sustainable means of transportation. They also assert that 96% of the time during which the cars are parked can be used to produce electricity by connecting to the national electricity network. However, the cars' ability to actually produce energy on the distributed energy production network isn't feasible. Furthermore, it is highly inefficient. This is the "illusion of the hydrogen economy".



*Chapter 16 (The Last Chapter)
      : We should implement measures to curb CO2 levels only when the following is proved and verified:
1) Greenhouse gases contribute much more to higher temperatures than the natural cycles of change in the Earth's climate
2) Global Warming causes great harm to human welfare and ecosystems
3) Reasonable human activity accelerates Global Warming
aaa: For every argument, some researchers provide evidence for one side while others provide for the other. This book support those who say Global Warming isn't caused by human activity. This would also be the side that says we don't have to change our practices and lifestyles since there isn't sufficient evidence to prove that we should. I'm not sure this is the wise direction to take. What if it's too late to take measures when all evidence begin to point towards the other side? 

Even as the authors mentioned in various points of the book, we still do not have a complete picture of how our planet works. Trends and cycles in our Earth's system is very complex; it includes the 1,500-year cycles that the authors love, it also involves the Greenhouse Effect that they dismiss. Can we be absolutely certain which evidence is stronger than the other, and which findings are the ones to implement in our policies and practices? In my humble opinion, we should at least try not to accelerate the activities that could be damaging our environment. I also believe we should be able to make some sacrifices - even if the logic behind them isn't absolute - because they could make all the difference to our posterity. Choosing to take no action would be irresponsible when some of the evidence, regardless of their imperfections, says we shouldn't. 


      : Although we cannot prevent damage from global climate change throughout the entire globe, we can develop the technologies to minimize its influence on our society. For example, we can provide enough food through mass production and send such resources to regions that need them. 
     This idea is valid only when this is certain: we ourselves do not exacerbate global climate change. If it is found that we do accelerate Global Warming, what the authors suggest would be attempting to clear up after the catastrophe instead of actively making an effort to prevent it. Can we really afford to simply prepare for the scenario that could be averted in the first place?

Skeptics and Deniers: Global Warming and Mass Extinction - continued

Last post of the Skeptics and Deniers series was on Global Warming and Mass Extinction. This blog post will be its continuation, discussing the various factors that threaten wildlife.

The writers list four 'confirmed' factors:
1. Asteroid Collisions
2. Hunting
3. Agriculture
4. Introduced Species

Since the writers do not believe that Global Warming endangers wildlife, they give the factors that are not directly related to the current climate change. It provides an outline of the threats throughout time, giving a  glimpse of the  complex relationships between a species and the environment and also among species. 

There was an interesting piece of information linked to factor #3: although humans have taken over one third of the world's land for agricultural purposes, the land suited for farming is likely to to have been providing habitat for a small number of species. However, I have to take issue with what the book says soon afterwards: that because we choose land with high productivity for farming (more suited for agriculture), we leave out the rest of the world's land (on which more species live) to "nature". Are the writers implying that humans take control of land just for farming and do not use the rest for other purposes? If there is a reason for this misrepresentation, perhaps the writers are trying to give the impression that we do not impose that great an influence on the environment. It certainly wouldn't be a hindrance to the writers' opinion that human activity cannot have such a big impact as to cause an anthropogenic climate change...

Factor #4 was another point that I gave more thought to. It states that the development of transportation unintentionally brought new species to foreign land. Ships, cars, and planes meant the introduction of species to distant regions around the world. The book explained that the competition between the native and foreign species was inevitable, causing some to become close to extinction. I wondered whether this conflicted with ideas presented further in the chapter. Giving examples of various species - the Northern Pika, birds of the eastern region of the United States, etc. - the writers offer the following idea: as a reaction to the changes in climate around the world, many species' original habitats may become unsuitable; however, the animals are "strong" and have an "inherent ability to adapt"; thus, the range of their habitat will simply shift, causing no definite harm to their survival. The writers explain that mentioned species have shown to survive moving to different regions and that others will do the same. And yet, what is so different about this situation that the various species survive in this case, and do not in the first scenario - the introduction of species by human transportation? Competition between species exists in both, does it not? Is it due to the number of animals being shifted? Is it about how long it takes to make the shift? Please tell me what you think in the comments below! 

The final post of this series will be posted soon~!

Yangjaecheon in Late December - Early February

Spring isn't quite here yet. There are icy puddles on the concrete, brittle branches trembling when birds flutter past, off-white leaves of feathery bristlegrass billowing in the wind, the sting on the tip of my nose. 

I've been taking walks along my beloved Yangjaecheon lately. I wanted to share my pictures with you. Some are blurry, some are grainy. I hope they capture the still serenity that I love about the stream - the gem that can only be observed in late winter mornings.

Skeptics and Deniers: Global Warming and Mass Extinction

The impacts of global warming on species outlined by the World Wildlife Fund:
http://wwf.panda.org/about_our_earth/aboutcc/problems/impacts/species/

Polar bears, sea turtles, clownfish, flamingos. These are only a few of the species that are known to be "threatened by climate change" and "endangered by global warming". We're aware that human activity has been contributing to global warming, driving many towards extinction. But what if someone told us that we're not, in fact, responsible for this? 

Fred Singer and Dennis Avery, in Chapter 6 of Unstoppable Global Warming: Every 1,500 Years, present the view that there is no proof animals become extinct due to rise in temperatures. As they support the idea that the current temperature trend is not anthropogenic, they state that we're not bringing about extinction of various organisms, at least not through warmer climates. They add that the development in certain technologies is the key to the protection of wildlife. They also criticize the sensationalist ways of some politicians and environmentalists in building their support for their work. This blog post will be exploring some of their ideas as part of the on-going Skeptics and Deniers series.


Have there actually been any cases of extinction?

In 2004, the international journal Nature published an article: Extinction Risk from Climate Change. It warned that global warming, caused by human activity, would wipe out approximately one million species of flora and fauna in the next half-century. Climate models predicted rapid changes in the ecosystem and ecological processes; the shifts in the Survival Envelope would lead to the elimination of many species. This article reflected the difficulty for most species to adapt or move habitat in time during the abrupt changes in the environment. The book, however, claims that this is contradictory to findings in other research.

Citing research in other scientific journals and literature, the book says that most of the world's animals formed the current physical forms in the Cambrian period, which was part of the Paleozoic era. The writers use this as a reason why it would be reasonable to assume that these animals, which survived more extreme climate cycles and conditions throughout all this time, would be able to survive the current climate change. They say that this intrinsic ability to adapt and evolve in new conditions is why we do not have to worry about extinction.

Here's a question. Have there been any recent instances of extinction due to the rise in temperatures? The writers' answer is "none". Some researchers anticipate the extinction of 20% of the world's wildlife species in the next forty years, which will likely show a 0.8°C increase. After this piece of information, the writers inform us that the last 150 years, which showed 0.6°C increase, resulted in no extinction of any species due to the rise in temperatures. 

When I read this part, something  sprang up to my mind. We cannot treat the change - rise in temperature - as itself alone. For example, if it was the increase in CO2 levels that brought about a warmer climate, we need to take Ocean Acidification into consideration. So, when the writers said that the rise in temperatures threatened no species towards extinction, I wondered: "How did they figure out the influences of just one factor - a warmer climate?"  I do assume that the researchers and writers would have studied all the influences and conditions before reaching their conclusion. Still, when I read a sentence later in the chapter - that no evidence that global warming kills coral reefs means the two are "not related in any way" - made me doubt whether the book was accurate, unbiased, and scientific. 


I'll be continuing my comments on Global Warming and Mass Extinction in the next post! Cheers :)

Skeptics and Deniers: Concerned about 'Sea Level Rise'?

We've all been there. Worrying about coastal floods penetrating our mega-cities, sinking tropical islands, breaking down our historical monuments, swallowing entire nations, forcing the new climate refugees to desperately seek shelter in already over-populated settlements. Throughout school, we've learned about global warming and the consequent thermal expansion of oceans and the melting of icebergs, causing sea levels to rise. Simply, it's something that's understood. 

This post is part of the series "Skeptics and Deniers"; you can read the previous posts here, here, and here. This post is about the claims that Fred Singer and Dennis Avery make on the rise of sea levels. In Chapter 4, they state that there have been greatly exaggerated estimates of sea level rise; that there are no reasons for us to anticipate 'big' increases in sea levels; and that we do not have to spoil our coastal wetlands to fortify our coast lines. We will explore some of their ideas in detail below.

1. The book takes issue with the findings from the Intergovernmental Panel on Climate Change.* The writers point out that the IPCC has modified its forecasts on sea level rise over the years. For example, the 1990 estimate of 30~100cm increase by 2100 changed to to 9~88cm in 2001. This statistic has 'a wide range of uncertainty'. 


You can read more on IPCC's findings here.
Suddenly, after such little background information on the work of IPCC, the book says that according to INQUA, the IPCC has ignored the research conducted by scientists on sea levels and coastal development. The IPCC, instead, uses the results from computer models that are not yet verified. The writers move onto the claims from the former president of Sea Level Commission: that the IPCC has inaccurate reports; that there have been no such indications of the sea level rise in the past 300 years; and that satellite images have shown no change in the past 10 years. He says that there is no reason for us to fear massive floods in our future. 

The writers add that the IPCC proposed 0.09~0.88m of sea level rise from 1990 to 2100, whereas experts from the Sea Level Commission suggested a 10cm(±10cm). The EPA, the US Environmental Protection Agency, reported that there is 50% chance for 45cm and 1% chance for 110cm increase in sea level by 2100. The writers assume that such statistics would have been partly intended to produce news reports that concentrate on the latter statistic. The concluding paragraph states that the scientists studying sea levels have anticipated no rise in sea levels in the 21st century.

I believe this was one of the sections  where I realized that this book holds so many overstatements, generalizations, and manipulations of facts. I was startled at the progression of information and the specific quotes used by the book. After such meager details on the findings of the IPCC, the writers use very strong words to present the idea that the IPCC has been unreliable, ignorant, imprecise, and scheming. Besides the IPCC's modifications, there are no other aspects of IPCC's faults explained in the writers' own words. Singer and Avery were sometimes very vague in their explanations e.g., not stating exactly what the IPCC has ignored in the research conducted by other scientists, not elaborating on the lack of evidence in the past several centuries. I wondered why the intellectuals that Singer and Avery are did not report findings or facts of their own. I was stunned at the extreme ways in which the writers led to their apparent conclusion: that the findings of some scientists that contrast with those of the IPCC mean ALL scientists studying sea levels do not forecast ANY rise in sea levels

*The IPCC is an international body of scientists that advises the UNFCC on the state of climate science. It creates periodic assessment reports on climate change, which are subject to four rounds of review by experts and government representatives. 


2. There are examples of specific regions that have shown little or no increase in sea levels. The book states O.W.Mason and J.W.Jordan's findings in 2002 show only a 0.25mm/year increase in the Chukchi Sea during the past 6,000 years. According to the aforementioned research team at the Sea Level Commission, the sea levels of the Maldives have actually demonstrated an approximate decrease of 20~30cm since 1970. Australia's National Tidal Facility has found no evidence that sea levels are increasing in Tuvalu


http://www.bbc.com/news/world-south-asia-12651486
I was quite surprised at this information. Maldives and Tuvalu are some of the most common examples used to demonstrate the dangers of rising sea levels. The Maldives Profile of the BBC News begins with the words "None of the coral islands measures more than 1.8 metres (six feet) above sea level, making the country vulnerable to a rise in sea levels associated with global warming." The Washington Times in April 19, 2009 stated that "Estimates released at the Copenhagen International Climate Congress in February say the sea could swallow most or all of the islands by the year 2100." The Tuvalu government for the 64th Session of the UN General Assembly stated that "there is a potential that the entire land surface of Tuvalu could disappear as a result of sea level rise." 

This brings us back to the issue mentioned in the previous post. What is the right thing to do when there are conflicting reports on the same issue? Before we are armed with all the knowledge and expertise for us to carefully evaluate the way the research was conducted, we cannot be hasty in making our own conclusions. So what should we do in the meantime? Is it reasonable to dismiss the reports on the dangers these areas are facing for the simple reason of lack of evidence? 


I will be putting up three more posts for this series in the next three weeks. I hope you have enjoyed the discussions on this topic so far. :)
