본 논문은 기후 부정의한 상황에 대한 정책 방향을 기후정의 관점에서 모색하기 위한 시론적 연구 이다. 전세계 곳곳에서 폭염, 호우, 가뭄 등 전례 없는 현상으로 나타나는 기후변화는 지구와 인류의 생존을 위협하게 되었고, 세계는 이에 대응하는 방법을 모색하고 있다. 그러나 2021년 11월에 개최된 26차 유엔기후변화협약 당사국총회(COP26)가 각국의 이익을 우선시하는 국가들에 의해 충분한 성과를 내지 못함에 따라, 국제적 기후변화 대응의 어려운 현실이 다시금 드러나게 되었다. 각국의 협의를 어렵게 만드는 요인 중의 하나는 기후변화가 내포하는 불평등에서 찾을 수 있다. 인류 모두에게 닥친 기후위기는 모든 사람들에게 동일한 정도의 피해를 주지 않으며, 기후변화를 초래한 대상과 피해자가 일치하지 않는 불평등의 문제를 갖고 있다. 탄소배출로 부를 축적하고 더 많은 탄소를 배출한 유발자와 그로 인한 피해자가 일치하지 않는 문제의 인식에서 ‘기후 부정의’와 ‘기후정의’가 논의되기 시작하였다. 기후위기의 부정의한 상황은 국가 간, 계층 간, 세대 간의 불평등을 악화시키고 기후위기 대응의 걸림돌이 된다. 본 연구는 기후위기의 부정의한 상황을 분석하고, 국제 사회와 한국사회의 대응 방향을 돌아보고자 한다. 기후정의 관점을 통해 기후위기의 불평등 문제가 드러나고 기후변화 대응책 마련에 유용한 분석틀을 제공할 수 있기를 기대한다.

기후변화는 동·식물의 서식지와 개체군을 감소, 소멸시키며, 생물다양성 보존에 위협이 되고 있다. 특히, 도롱뇽과 (Hynobiidae)에 속한 종들은 다른 분류군들에 비해 행동권이 작고, 분산 능력이 극히 제한되기 때문에 기후변화에 매우 취약한 분류군이다. 본 연구에서는 한국꼬리치레도롱뇽(Onychodactylus koreanus)의 관찰지점과 종 분포 모델링 기법을 바탕으로 국내 서식하고 있는 한국꼬리치레도롱뇽의 주요 분포지역과 서식특성을 파악하고 기후변화에 따른 분포변화를 예측하였다. 그 결과 고도가 그들의 분포에 가장 주요한 영향을 끼친 환경변수로 확인되었으며, 강원도와 경상북도와 같은 고도가 높은 산림 지역에 밀집된 분포 형태를 보였다. 이처럼 종 분포 모델에서 예측된 공간적 분포 범위와 서식특성은 선행 조사 결과를 충분히 포함하고 있었다. 기후변화에 따른 분포변화를 확인한 결과, 한국꼬리치레 도롱뇽은 현재 분포 범위에 비해 RCP4.5 시나리오에서 62.96% 가 감소할 것으로, RCP8.5 시나리오에서는 98.52% 감소할 것으로 예측되어 기후변화로 인해 서식 적합 공간들이 급격하게 감소하는 것으로 확인되었다. 모델의 AUC 값은 현재에서 0.837, RCP4.5에서 0.832, RCP8.5에서 0.807로 높게 측정되었다. 이러한 결과들은 기후변화로 인해 영향을 받는 양서류의 보전 대책 수립에 중요한 기초자료가 될 수 있을 것이다. 추후, 한국꼬리치레도롱뇽의 생활사에 따른 서식지 특성과 미세한 서식 요인들이 반영된 다양한 분석기법을 통한 추가적인 연구가 수행된다면 종 감소에 영향을 끼치는 주요환경 요인들을 밝혀낼수 있을 것으로 판단된다.

Climate change effects are particularly apparent in many cool-season grasslands in South Korea. Moreover, the probability of climate extremes has intensified and is expected to increase further. In this study, we performed climate change vulnerability assessments in cool-season grasslands based on the analytic hierarchy process method to contribute toward effective decision-making to help reduce grassland damage caused by climate change and extreme weather conditions. In the analytic hierarchy process analysis, vulnerability was found to be influenced in the order of climate exposure (0.575), adaptive capacity (0.283), and sensitivity (0.141). The climate exposure rating value was low in Jeju-do Province and high in Daegu (0.36–0.39) and Incheon (0.33–0.5). The adaptive capacity index showed that grassland compatibility (0.616) is more important than other indicators. The adaptation index of Jeollanam-do Province was higher than that of other regions and relatively low in Gangwon-do Province. In terms of sensitivity, grassland area and unused grassland area were found to affect sensitivity the most with index values of 0.487 and 0.513, respectively. The grassland area rating value was low in Jeju-do and Gangwon-do Province, which had large grassland areas. In terms of vulnerability, that of Jeju-do Province was lower and of Gyeongsangbuk-do Province higher than of other regions. These results suggest that integrating the three aspects of vulnerability (climate exposure, sensitivity, and adaptive capacity) may offer comprehensive and spatially explicit adaptation plans to reduce the impacts of climate change on the cool-season grasslands of South Korea.

In this article, firstly, we talk about why we respond to “climate change impacts in nature and society” educationally. Secondly, we try to find ways that Jeju also has the ability to halt biodiversity loss and apply nature-based solutions to conserve biodiversity, enhance resilience, and so improve the well-being of the people on the island and in turn to improve the well-being of the people on the planet at the grass roots level of UNESCO internationally protected areas. Thirdly, we try to develop World Environment University Online School Leads Establishment of World Environment University so called “Lead WEU.” We will announce “World Environment University Online School Leads Establishment of World Environment University” at Private Meeting of the 2020 World Conservation Congress on September 9, 2021 in Marseille of France. We propose ”Jeju Global Governance of World Heritage; Climate Change Impacts and Integrated Management of UNESCO internationally Protected Area, at the graduate class of Jeju National University from September 2 to December 9, 2021. The core program centered at the University itself would be developed initially on the basis of the comparative advantage offered by its location in Jeju and the quality of faculty, full and part time, that could be recruited to the University.

Global warming affects critical natural resources, one of which is the oceans that occupy 70% of the total cover of the earth. In other words, ocean warming is a subset of global warming which needs to be addressed urgently. Purple laver (pyropia spp.) is one of the most vulnerable items to climate change although it is a major export product of Korean fisheries. The purpose of this study is to analyze the causality of how climate change caused by global warming affects the increase or decrease of PLP (purple laver production). The target area for analysis was set to Maro-hae between Jindo-gun and Haenam-gun. We selected marine environmental factors and meteorologic factors that could affect PLP as variables, as well as co-integration tests to determine long-term balance, and the Granger causticity tests. As a result, PLP and marine environmental factors WT (water temperature), pH, and DO confirmed that long-term equilibrium relationships were established, respectively. However, there is only causality with WT and it is confirmed that there is only a correlation between pH and DO (dissolved oxygen). There was no long-term equilibrium relationship between PLP and HDD (heating degree days) and there is a causal effect that HDD affects PLP; however, it was less clear than that of WT. The relationship between PLP and RF (rainfall), WS (wind speed), SS (percentage of sunshine), and FF (farm facilities) was all balanced in the long term, and causality exists. Based on the results of the analysis, policy proposals were made.

Using data from flies collected with pitfall traps in 365 forests on a nationwide scale in Korea, the abundance and distribution changes of two families (Phoridae and Lauxaniidae) in Korean forests were predicted at the genus level according to two climate change scenarios: RCP 4.5 and RCP 8.5. The most suitable temperature for the 17 major genera was estimated using a weighted average regression model. Stichillus and Anevrina displayed the lowest optimum temperature with 7.6℃ and 8.5℃ in annual mean temperature, respectively, whereas Chonocephalus had the highest optimum temperature with 12.1℃. Among thirty genera, seven genera (four from Phoridae and three from Lauxaniidae), which showed their abundance in a bell-type or linear pattern along the temperature gradient, were used for predicting the distribution changes according to the future climate change scenarios. All the taxa of this study are expected to decrease in abundance and distribution as a function of temperature increase. Moreover, cold-adapted taxa were found to be more affected than warmadapted taxa.

We aimed to predict the Italian ryegrass (IRG) productivity change of introduced and domestic varieties based on climate factors and identify suitable areas for IRG cultivation using the RCP 8.5 scenario. The minimum mean air temperature in January showed the highest correlation with productivity. The ratio of possible and low productivity areas was high in Gangwondo, and the ratio of suitable and best suitable areas was relatively high in the central and southern regions in the past 30 years. The change in the IRG cultivation area was found to be 26.9% in the best suitable area between 1981–2010 but increased significantly to 88.9% between 2090s. In the IRG suitability comparison classes between domestic and introduced cultivars, the ratio of suitable and best suitable areas was relatively high in the domestic varieties during the past 30 years. However, there is almost no difference between the IRG domestic and introduced varieties in the IRG suitability classes after the 2050s. These results can predict changes in the IRG suitability classes between domestic and introduced cultivars according to the climate change scenario, but there are limitations in accurately predicting the productivity of IRG because the results may vary depending on other environmental factors.

기후변화는 생물계절반응 변화와 식물 자생지 이동을 초래한다. 우리나라 상록활엽수림도 과거 20년에 비해 분포역이 넓어지고 있으며, 자생지 범위가 북상하고 있다. 이에 따른 녹나무과 상록활엽수의 자생지 변화 예측을 위해 먼저, 식생의 분포와 관련이 깊은 온량지수와 한랭지수, 최한월 최저기온, 연평균기온 등 기후지표를 분석하였다. 그 변화량과 공간분포분석 을 통해 우리나라 난온대 지역에 분포하는 녹나무과 상록활엽수 8종의 자생지 기후지표특성을 파악하였다. 또한, 기후지표특성 을 바탕으로 MaxEnt 종 분포모형을 적용하여 기후변화 시나리오(RCP 4.5/8.5)에 따른 21세기 자생지 변화를 예측하였다. 녹나무과 상록활엽수 8종의 자생지 월 평균 기후지표 특성은 온량지수 116.9±10.8℃, 한랭지수 3.9±3.8℃, 연강수량 1495.7±455.4㎜, 건습지수 11.7±3.5, 연평균 기온 14.4±1.1℃, 동계 평균 최저기온 1.0±2.1℃로 나타났다. 기후변화 시나리 오 RCP 4.5에 근거한 녹나무과 상록활엽수의 분포는 전라남도와 경상남도를 포함하는 도서지방과 서·남해안의 인접지역, 동해안의 강원도 고성까지 분포가 확대되는 것으로 분석되었다. 기후변화 시나리오 RCP 8.5에 근거한 분포의 경우 전라남도 와 경상남도의 전 지역과 전라북도, 충청남도, 경상북도, 수도권의 일부 지역을 제외한 대부분 지역으로 분포가 확대될 것으로 분석되었다. 기후변화에 대비한 녹나무과 상록활엽수의 보전을 위해서는 자생지 내·외 보전 기준설정 및 다양한 자생지 특성 분석이 수행되어야 한다. 또한, 기후지표를 기반으로 한 생물계절정 자료를 통해 기후변화에 따른 녹나무과 상록활엽수의 분포, 이동, 쇠퇴 등의 미세변화를 선제적으로 감지하고 보전관리 방안을 수립하여야 할 것이다.

In this study, we analyzed the development of high school students’ argumentation through their writings on socio-scientific Issues (SSI) related to the Climate Change Unit in the Earth Science I curriculum. Pre- and post-writing assignments on the two main causes of global warming were analyzed and compared. In addition, an in-depth interview of the focus group was conducted with 7 students who showed a distinct change in the level of argumentation. According to the results, 16 of 52 students remained at the same argumentation level in pre- and post-writing assignments, and students remaining at Level 2 among five levels had difficulty in understanding the Toulmin’s argument pattern (TAP) structure. Using the TAP structure, 29 of 52 students demonstrated increased argumentation levels in the post-writing assignments. The conclusions include that writing lessons on SSI using the TAP in Earth science classes can improve the level of high school students’ argumentative writing, and that the level of students’ argumentation can develop with the elaboration of their level of falsification. Also, it is suggested that the science curriculum should increase students' science writing competencies by specifying science writing as one of the goals.

This study was conducted to investigate cucumber plants response to greenhouse environments by solar shading in greenhouse in the summer. In order to estimate heat stress reduction of cucumber plants by solar shading in greenhouse, we measured and analyzed physiological conditions of cucumber plants, such as leaf temperature, leaf-air temperature, rubisco maximum carboxylation rate, maximum electron transport rate, thermal breakdown, light leaf respiration, etc. Shading levels were 90% mobile shading of full sunlight, 40% mobile shading of full sunlight and no shading(full sunlight). The 90% shading screen was operated when the external solar radiation is greater than 650 W·m-2. Air temperature, solar radiation, leaf temperature, leaf-air temperature and light leaf respiration in the 90% shading of full sunlight was lower than those of 40% shading and no shading. Rubisco maximum carboxylation rate, arrhenius function value and light leaf respiration of the 90% shading were significantly lower than those of 40% shading and no shading. The thermal breakdown, high temperature inhibition, of 90% shading was significantly higher than that of 40% shading and no shading. Therefore, these results suggest that 90% mobile shading made a less stressful growth environment for cucumber crops.
