The purpose of this study was to identify the effectiveness of concepts on global warming, practical will and belief on global warming mitigation by experiments based on global warming program. For this study, 60 $6^{th}$ grade students were selected in two elementary schools. They were divided into an experimental group and a control group. The students of the experimental group took part in global warming program focusing experiments for 10 lessons during 2 weeks. The students of the control group were taught according to the regular curriculum of $6^{th}$ grade about global warming. To identify the effects of this program, both groups' students were tested on concepts on global warming, practical will and belief on global warming mitigation before and after the program implementation. Also the students of the experimental group wrote an essay and gave an interview about the program after implementation. The results were that the experimental group gained higher scores than the control group in the concepts on global warming. The programs improved students' practical will and belief on global warming mitigation. Also this program showed that the students systematically understood on global warming than existing classes in the regular curriculum.

As the influence of mankind's actions grows on the earth's climate, the necessity of climate change education is increasing everyday. Therefore, this study will discuss desirable courses about climate changes education that can be used throughout the world. It is meaningful to try to compare the contents and scope of earth global warming education courses of different nations. where education and a research about earth global warming occur simlutaneously. This is key because global warming is not just a national issue, but an international issue. Therefore this study need to understand the status of environmental education is over the world to devise an improvement plan help to solve the problem of climate change on an international level. Therefore, this study compared, the global warming educational contents which appeared in Korean textbooks to Japanese and American textbooks, and analyzed commonalities and differences of each. Also, we will discuss desirable global warming educational instructional strategies. This study analyzed the present situation of nations by looking at common points and differences using an analysis form. Even though the researchers of an each nation analyzed the teaching material through common analysis forms, this study utilized a common analysis method with a colleague researcher regarding environmental education, environment, environmental science to increase the validity of the study in each nation. Also the difference and similarities were aggregated as This study collected the analysis results of each nation. The researchers utilized the results of the analyses to engage in repeated discussion and the sharing of results.

The purpose of this study is to develop the elementary environmental textbook relevant to global warming based on responsibility ethics. To achieve the purpose, concrete study processes are as follows. First, the theory of responsibility ethics of Jonas was analyzed. Second, contents relevant to global warm ing on textbooks and guide books in the 7th elementary curriculum was analyzed through reference study. Third, the environmental textbook relevant to global warming for 5th and 6th grade in the elementary school was developed which was based on responsibility. The results of this study are as follows. First, responsibility ethics of Jonas has a lot of merit if it is applied to environment education. Second, according to the analysis into textbooks and guide books in the 7th elementary curriculum, the contents concerning global warming are very poor in both quantity and quality. Third, the elementary environmental textbook relevant to global warming for 5th and 6th grade students was developed. This textbook based on responsibility ethics will be expected to be efficient on the learning compared with subsidiary textbook in use.

This study is about interdisciplinary education model of using Davis Guggenheim's documentary film on global warming which is a big concern in climate change issues, An Inconvenient Truth. It based on Al Gore's slide speech. Through a course student analyzed the cause and phenomenon of global warming resulted from increase of $CO_2$ by using fossil fuel and its environmental science effects-heat wave, desertification, tornado, hurricane, sea level rise caused by melting glaciers, destroying ecosystem like habitat degradation of wild animals, for example polar bear, extreme cold wave caused by change of ocean currents- of global warming. After, student discussed of efforts to prevent global warming. This educational model is appropriate for lower grade student of environmental engineering and also available for converged majors or general education class.

The purpose of this study was to investigate elementary and middle school (grade 5 and 7) students' perceptions of global warming and climate change. A total of 239 students completed opened-form questionnaire consisting of cartoons regarding global warming and climate change. The results showed that are as follows. Elementary and middle school students had low level of perception of global warming and climate change. A majority of students rightly believed that the global warming is related to greenhouse gases, glacier, environmental pollution, etc. Also, Many students had scientific concepts about the cause of global warming while some of the students had misconceptions that destruction of the ozone layer will cause an global warming. We have found that some of the students of elementary and middle school had confused between the cause of global warming and ozone depletions.

The purpose of this study was to investigate elementary student teachers' conceptions about the mechanism of the greenhouse effect, the greenhouse gases, the global warming, and their learning experiences of the greenhouse effect and the global warming. Participants were 82 student teachers in their second year of studies (science education: n=28, not science education: n=27) and in their fourth year of studies (science education: n=27). The open-ended questionnaire was used to examine the teachers' spontaneous ideas depicted by their drawings and/or writings. The results of this study are as follows: First, the student teachers' scientific response rate about key concepts related to the mechanism of the greenhouse effect was low (6.1%~28.0%); Second, although there are various greenhouse gases, it was only carbon dioxide that the student teacher's response rate was more than 80%; Third, only 17.1% of the student teachers clearly distinguished the greenhouse effect and the global warming; Fourth, there was a tendency that the student teacher group in the fourth year of studies and science education showed higher scientific response rate about the concepts than the other two groups.

Despite the greenhouse gases like carbon dioxide have steadily increased in atmosphere, the overall trend of the global average surface air temperature has stalled during the last decade (2002-present). This phenomenon is often called hiatus or warming pause, which is challenging the prevailing view that anthropogenic forcing causes warming environment. Our study characterized the hiatus by analyzing the HadGEM2-AO (95 yrs) simulation data based on RCP8.5 scenario. The PC2 time series from the EOF of the zonal mean vertical ocean temperature has been defined as the index that represents the warming pause. The relationship between the hiatus, ENSO and the changes in climate system are identified by utilizing the newly defined PC2. Since the La Nina index (defined as the negative of NINO3 index) leads PC2 by about 11 months, it may be possible that the La Nina causes the warming to be interrupted. We also show that the cooling of the climate system closed tied to the heat penetration into the deep ocean, indicating the weakening the warming rate is due to the oceanic heat uptake. Finally, the global warming hiatus is characterized by the anomalous warming in Arctic region as well as the intensification of the trade wind in the equatorial Pacific.

The purposes of this study are: (1) to develop educational program designed to improve high school students' knowledge integration and their system thinking skills about global warming and (2) to identify the change of students' system thinking level. The developed program was implemented to twenty seven high school students, and six students grouped into three highs and three lows in their performance were selected to analyze their level of system thinking. The word association, casual map and drawing were used to measure and identify any significant change. As a result, the low level system thinking group improved their system thinking skills for global warming and the earth and sub-systems after the intervention. However, participants' misconception remained the same. And the high level systems thinking group showed more organize system thinking skills about a global warming topic. It is suggested that more educational programs be developed on various topics in order for high school students to improve their systems thinking skills as well as knowledge integration of earth systems and earth environment in school curriculum.

Global warming affects forests and their ecology. Diversity in the forest is a buffer that reduces the damage due to global warming. Mixed forests are ecologically more valuable as versatile habitats and are effective in preventing landslides. In Korea, most forests were created by simple afforestation with trees of evergreen species. Typically, evergreen trees are shallow-rooted, and deciduous trees are deep-rooted. Mixed forest tree roots grip the soil effectively, which reduces the occurrence of landslides. Therefore, improving the distribution of tree types is essential to reduce damage due to global warming. For this improvement, the investigation of tree types of the forest is needed. However, determining the tree type distribution of forests that are spread over wide areas is labor-intensive and time-consuming. This study suggests effective methods for determining the distribution of tree types in a forest that is spread across a relatively wide area. Using normalized difference vegetation index and RGB images from unmanned aerial vehicles, each evergreen and deciduous tree, and grassland area can be distinguished. The distinguished image determines the distribution of tree type. This method is effective compared to directly determining the tree type distribution in the forest by the use of manpower. The data from these methods could be applied to plan a mixed forest or to prepare for future damage due to global warming.
