What Made South Korea the Saddest Country in the OECD? (Part 2)

This is Part 2 of my efforts to explain why South Korea's suicide death rates are the highest in the OECD.
As signs of South Korea's gloomy social environment, I am presenting six figures that are copied from two OECD reports published in 2013.
(For the full names of countries, please see the note at the end of this article.)

The first figure shows how much of income inequality is reduced by taxes and cash transfers. Korea is the worst country in reducing income inequality by those measures.

Source: Denk et al. (2013)

The second figure shows the share of cash transfers in each country's Gross Domestic Product. Korea has the second smallest share of cash transfers (next to Mexico) among OECD countries.

Source: Denk et al. (2013)

The third figure shows the share of social spending in each country's Gross Domestic Product. Korea has the smallest share of social spending among OECD countries.

Source: Égert (2013)

The fourth figure shows the ratio of each country's public spending or benefit for the people who are disabled or with limited capacity, relative to the country's Gross Domestic Product. Korea has the smallest shares of those expenditures among OECD countries.

Source: Égert (2013)

The fifth figure shows the share of public spending for family benefits in each country's Gross Domestic Product. Korea has the smallest shares of those measures among OECD countries. That's a reason why Korea's fertility rate is the lowest in the group.

Source: Égert (2013)

The sixth figure shows the poverty rates of old people (65 years old or older). Korea shows the highest old-age poverty rate among OECD countries.

Source: Égert (2013)

Then, what could be done to remedy these symptoms?

Universal Goals and National Targets for the UN's Post-2015 (Post-MDG) Development Agenda

Here, I am copying the "Universal Goals and National Targets" for the UN's "Post-2015 Development Agenda". The Post-2015 Development Agenda is replacing the Millennium Development Goals.

PRIORITIES: FIVE TRANSFORMATIVE SHIFTS
  1. Leave No One Behind. We must ensure that no person – regardless of ethnicity, gender, geography, disability, race or other status – is denied basic economic opportunities and human rights.
  2. Put Sustainable Development at the Core. We must make a rapid shift to sustainable patterns of production and consumption, with developed countries in the lead. We must act now to slow the alarming pace of climate change and environmental degradation, which pose unprecedented threats to humanity.
  3. Transform Economies for Jobs and Inclusive Growth. A profound economic transformation can end extreme poverty and promote sustainable development, improving livelihoods, by harnessing innovation, technology, and the potential of business. More diversified economies, with equal opportunities for all, can drive social inclusion, especially for young people, and foster respect for the environment.
  4. Build Peace and Effective, Open and Accountable Institutions for All. Freedom from violence, conflict, and oppression is essential to human existence, and the foundation for building peaceful and prosperous societies. We are calling for a fundamental shift – to recognize peace and good governance as a core element of wellbeing, not an optional extra.
  5. Forge a New Global Partnership. A new spirit of solidarity, cooperation, and mutual accountability must underpin the post-2015 agenda. This new partnership should be built on our shared humanity, and based on mutual respect and mutual benefit.
UNIVERSAL GOALS, NATIONAL TARGETS
Notes:
1: Candidates for global minimum standards, including ‘zero’ goals.
2: Indicators to be disaggregated.
3: Targets require further technical work to find appropriate indicators.
Universal Goals National Targets
1. End Poverty 1a. Bring the number of people living on less than $1.25 a day to zero and reduce by x% the share of people living below their country’s 2015 national poverty line 1, 2
1b. Increase by x% the share of women and men, communities, and businesses with secure rights to land, property, and other assets 2, 3
1c. Cover x% of people who are poor and vulnerable with social protection systems 2, 3
1d. Build resilience and reduce deaths from natural disasters by x% 2
2. Empower Girls and Women and Achieve Gender Equality 2a. Prevent and eliminate all forms of violence against girls and women 1, 2, 3
2b. End child marriage 1, 2
2c. Ensure equal right of women to own and inherit property, sign a contract, register a business and open a bank account 1, 2
2d. Eliminate discrimination against women in political, economic, and public life 1, 2, 3
3. Provide Quality Education and Lifelong Learning 3a. Increase by x% the proportion of children able to access and complete pre-primary education 2
3b. Ensure every child, regardless of circumstance, completes primary education able to read, write and count well enough to meet minimum learning standards 1, 2
3c. Ensure every child, regardless of circumstance, has access to lower secondary education and increase the proportion of adolescents who achieve recognized and measurable learning outcomes to x% 1, 2
3d. Increase the number of young and adult women and men with the skills, including technical and vocational, needed for work by x% 2, 3

The Keeling Curve Reaches 400 ppm CO2

For the first time since the measuring of the atmospheric carbon dioxide concentration began in 1958, the Keeling curve surpassed the 400 ppm CO2 milestone on May 9, 2013.

The CO2 censor reading at the Mauna Loa Observatory on May 09, 2013: 400.03 ppm

Worsening planetary energy imbalance and climate change

The existence of anthropogenic climate change has firm scientific evidence, no matter what global warming denialists say with no evidence or with interests (Hansen, Sato, & Ruedy, 2012; Washington & Cook, 2011). Although many ill-informed politicians, self-interested organizations, and even some scientists in non-atmospheric circles tried to discredit science of climate change (Nordhaus, 2012), global warming represented by a figure called “hockey stick” is undeniable (Mann, 2012).

Recent estimates of Earth’s energy budget clearly indicate that anthropogenic global warming is happening at annual net energy gain rates of 0.6±0.4 W/m2 (i.e., 0.6 = 340.2 (incoming solar) − 239.7 (outgoing longwave radiation) − 99.9 (reflected solar) W/m2) over 2000-2010 (Stephens et al., 2012). To be more specific, the net energy imbalance was annually 0.9 ± 0.5 W/m2 over 2000-2005 (Trenberth & Fasullo, 2012) and 0.58 ± 0.15 W/m2 over 2005-2010 (Hansen, Sato, Kharecha, & von Schuckmann, 2011). This energy imbalance is mainly caused by burning fossil fuels (Dukes, 2003), the vast majority of which had been stored underground for millions of years before the Industrial Revolution began to utilize coal steam engines from around 1760. Instead of searching for alternative and more sustainable energy sources, globalized energy industry is “ripping apart the earth” to extract more fossil fuels (McKibben, 2012).

Because the environment is “warmer and moister than it used to be” (Trenberth, 2012, p. 7), all weather events as well as extreme ones are affected by the current climate change. Hurricane Katrina in August 2005 (Graumann et al., 2006) was a dramatic symbol of how human inaction will worsen the climate change and harm humans themselves (Karl, Melillo, & Peterson, 2009; Lynn, Healy, & Druyan, 2009). Hurricane Sandy in October 2012 wreaked more havoc on lower Manhattan in New York and shorelines in New Jersey by exacerbated storm surge due to sea-level rise, which is undeniably caused by human induced global warming (Gillis, 2012).

Therefore, sustainability cannot be achieved without climate change mitigation. One of the most evident ways to minimize the adverse effects of human activities is to minimize greenhouse emissions, as suggested by the Intergovernmental Panel on Climate Change (IPCC) (Core Writing Team, Pachauri, & Reisinger, 2007). The more we delay to reduce greenhouse gas emissions drastically, the harder it becomes that we contain global warming within manageable limits. However, time is running out (Ranger et al., 2012; van Vliet et al., 2012). The latest estimation for the global carbon dioxide emissions in 2012 shows a trend worse than the IPCC’s worst warming scenario (Peters et al., 2012).

Although some recent studies indicate that imminent peak production of fossil fuels will eventually limit global CO2 emissions (Rutledge, 2011; Vernon, Thompson, & Cornell, 2011), even their analyses can be counter-argued by scientists’ analyses showing even fossil fuel reserves that are significantly lower than IPCC scenarios can induce catastrophic climate changes (for example, Kharecha & Hansen (2008)). We have to prepare for worst cases by reducing emissions right now (Oreskes, Stainforth, & Smith, 2010).

Then what should be our goal for climate change mitigation? It is widely accepted that we have to confine global warming within 2 °C above the pre-industrial global average temperature (Knopf, Kowarsch, Flachsland, & Edenhofer, 2012; UNEP, 2010; UNFCCC, 2010). According to the IPCC’s new climate change scenario called Representative Concentration Pathways (Moss et al., 2008), the organization’s targets in 2100 to limit global surface temperature change within 2 °C since industrialization is 2.6 W/m2 of radiative forcing increase since industrialization and the CO2 equivalent concentration of greenhouse gas should be limited to 450 ppm (van Vuuren et al., 2012). By definition, all values for the pre-industrial era should be based on those of the year 1750 (Core Writing Team et al., 2007, p. 36). However, climate models of the IPCC run their simulations by setting the benchmark year as any year between 1765 and 1850, for there are not a significant change in greenhouse gas concentrations during the period (Meinshausen et al., 2011).

How much is the amount of greenhouse gas emissions that are equivalent of the warming limit? It is recently estimated that we have to reduce our CO2 emissions by more than 80% compared to a peak emissions to stabilize a CO2 concentration at any chosen target level within a century or so (Committee on Stabilization Targets for Atmospheric Greenhouse Gas Concentrations, 2011).

Then what are we humans doing to achieve the target? Sadly, we are not doing enough, if not nothing. Although the Kyoto Protocol and its child EU ETS have given us a small bit of hope, the skepticism of environmentalists and scientists against any kind of selfless negotiations between nations turned out to be right. Copenhagen Climate Change Conference (COP15/CMP5) held in 2009 didn't produce any tangible, legally-binding agreement between nations. Its outcome, the Copenhagen Accord, just voiced the world’s agreed concern that global average temperature 2 °C warmer than pre-industrial age was unacceptable (UNFCCC, 2010).

The outcome of Durban Climate Change Conference (COP17/CMP7) held in 2011 was creation of an “Ad Hoc Working Group on the Durban Platform for Enhanced Action” (“Durban Platform”). COP17 just promised that the Durban Platform will prepare a legally binding protocol ratified by countries no later than 2015. But this time, global leaders admitted that holding global average temperature increase below 2 °C above pre-industrial levels might not be sufficient to avoid anthropogenic catastrophe and began to mention 1.5 °C (UNFCCC, 2012).

Today, I don’t have an answer about what we have to do for real outcome for global climate change mitigation. In my future post, I’ll search for promising answers.
