Climate change in South Korea

In recent decades most countries have been experiencing huge industrial progress. Urban and industrial areas in South Korea also had fast development from 1960s to 1980s.[1] Industrialization and the increase in population have produced various pollutants and greenhouse gases, which are anthropogenic factors for climate change. South Korea is experiencing changes in climate parameters, including annual temperature, rainfall amounts, and precipitation.[2] The most distinct climate change predicted for South Korea is an increase in the range of temperature fluctuation throughout the four seasons. The number of record minimum temperature days has decreased rapidly, and maximum precipitation during the summer has increased. Ongoing global climate change has produced local climate changes and extreme weather that affects: social, economy, industry, culture, and many other sectors.[3] The increased possibility for new types of strong weather damage evokes the seriousness and the urgency of climate change. To quickly adapt to climate change, the South Korean government began an effort to reduce greenhouse gas emissions, and is one step closer to having a low-carbon based socio-economic nation.[4]

Climate changed

Precipitation increase

Seoul, capital city of South Korea, has 227 years of precipitation records Cheugugi, which is the longest continual instrumental rainfall collection in the world. The record of daily precipitation provides a high-resolution dataset for detecting the singularity of extreme weather events and the multiple decades of precipitation variability. The Cheugugi observed precipitation from year 1778 to 1907, and modern observation equipment was developed and has been used since 1908. Comparing the Cheugugi period and the modern period, the modern period shows a significant increase in mean rainfall rate. For example statistic data for summer precipitation at Cheugugi period is 861.8 mm whereas that for the modern period mean is 946.5 mm.[5]

As the amount of rainfall in the last 10 years has increased because of the number of heavy rain and torrential rain events having increased in frequency, the risk of heavy rain has become much higher on the southern part of peninsula than the central region of the Korea peninsula. A large amount of water vapor entering the southern part of the peninsula (Southern coast, Jeju Island) flows into the Yellow Sea in summer and creates a high frequency of torrential rains. On the other hand, the east coast shows a low torrential rain frequency. As of 1990, over the past 20 years and over the most recent 20 years the torrential rain frequency data show a 25% increase in torrential rain watches and a 60% increase in heavy rain warnings.[6]

Changes in precipitation

The tropical rain belt ‘Changma front’ is created in the Bay of Bengal and the western North Pacific as a sub-system of East Asian Monsoon. The northward movement of the ‘Changma front’ is influenced by the development of the subtropical ridge.[7] This northward moving quasi-stationary front is called 'Changma' in South Korea, which represents the main precipitation period.[3][6] The ‘Changma front’ takes about 4 to 5 weeks to go through the Korea Peninsula. This slow movement results in a large, but steady, amount of summer rainfall over the entire Korea Peninsula in late June and July each year. In recent years, the ‘Changma front’ tended to move quickly, taking less than 3 weeks to go through the Korea Peninsula while pouring down heavy rain showers, along with various sizes of storms from late July to early August.[2] It means that we are having more extreme weather and localized heavy rain occurring after ‘Changma’.[8] The dynamics of the ‘Changma’ rains in the early summer, which derive from baroclinic disturbances that are strongly modified by latent heat release, remain poorly understood. While an increase in rainfall in the absence of the monsoonal circulation shifts is expected, relatively modest shifts or changes in timing can significantly affect East Chinese, Korean and Japanese climates.[9]

Temperature increases

Since 1999, the Korea Global Atmosphere Watch Center located at Anmyeon-do has been monitoring major greenhouse gasses (GHG) such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and chlorofluorocarbons (CFC-11 and CFC-12). The Anmyeon-do station is located in a relatively pollution-free environment, an ideal site for observing the background atmosphere of Northeast Asia, including the Korean Peninsula. Among these GHG, CO2 acts most to change many aspects of the climate factors.[10] The CO2 concentrations at Anmyeon-do are substantially higher than the global average; the average CO2 concentration for 2011 was recorded as 395.7 ppm, an increase of 25.0 ppm (6.7%) relative to the annual average of 370.7 ppm for 1999, and 5.2 ppm higher than the global average of 390.5 ppm for the same year as documented by NOAA/GMD.[11] The annual growth rate of CO2 for the 13-year period from 1999 through 2011 was 2.16 ppm/year, which was higher than the global average of 1.9 ppm/year, but it has slowed in recent years.[10] During the industrialization era (second industrial revolution) over the past few decades, people have been burning fossil fuels (coal, oil, gasoline, natural gas), which releases CO2 into the atmosphere, causing the greenhouse effect.[12] A sharp temperature contrast is shown between the urban and rural areas due to this industrialization. The mean temperatures data variations observed at ten meteorological stations in South Korea show an annual mean temperature increase at a rate of 0.52 °C per decade. During the last 29 years, the increase in the annual mean temperature was 1.5 °C for the Seoul station (found in an urban area) and 0.6 °C for the rural and seashore stations. These rate differences are significantly larger over urbanized areas.[2] South Korea is experiencing a rapid temperature increase,increase Daily maximum and minimum temperatures are very likely to increase in East Asia, resulting in more severe warm extremes, but less severe cold extremes.[9] These mean temperature increases, especially the temperature increase rate after the 1950s is 1.5 times higher than before the 1950s. The duration of winter is also projected to be a one month shorter than before, therefore having spring and summer will be 20 days longer more during the 1990s compared to what they were during the 1920s seasonal distribution.[13] When average temperature comparison for comparing 20th-century and 21st-century temperature averages, it is shown that there is a 4 °C increase. The mean yearly temperature for South Korea is 10~15 °C,[14] which means that the Korea Peninsula will soon become a subtropical region with an average temperature of over 27 °C. The recent subtropical zone is located on the lower seaside of Korea Peninsula, but as accelerated temperatures increase, it will result in the subtropical zone move migrating northward. Therefore, by 2100 the subtropical zone is projected to expand its region to the north end of Taebaek Mountains.[13]

Response to climate change

Government response: Carbon tax

Even though Korea is not a mandatory country to start carbon tax policy, The government is anticipating a carbon tax policy to prepare for the future trend of the carbon marketplace. They released a carbon reduction policy to reduce 30% of Business-as-usual (BAU) carbon production until the year 2020. Having a carbon tax is going to increase the burden on Korean companies that are highly dependent on manufacturing which emits a lot of carbon dioxide. Also, it will eventually increase the production cost, resulting in South Korean companies to becoming less competitive then than other global companies. Therefore Korean companies are now investing in developing new technology that will effectively reduce CO_2 while also constructing a cooperation agreement to share its new technologies and reinforce its eco-friendly campaign.[15] Green IT is a response to climate change and energy savings that will solve the pending issues between the other countries involved in the campaign. Therefore countrywide comprehensive and systematic policy formulation and project implementation is needed. The South Korean government will require more practical comprehensive measures that will contribute to Green IT industry.[16]

Company response: Green IT industry

A new Korean Government IT strategy project is projected to have a 20% increase in green IT and [18]
