The problems in coastal and ocean area related with climate change have continued to receive a high level of attention. Elevate average of sea level, variation in significant wave height and increased ocean temperature are linked to global climate in many ways. Thus, climate variability and future climate change should become a major interest for engineer, stakeholders, and decision makers, especially for developing strategies for mitigation and adaptation for future coastal development. The objective of this paper is to analyze the impacts of global climate change to Indonesian ocean environments due to global warming. This paper focus on the impacts of climate change to sea level, wave climate and sea water temperature. Increasing trend of sea level rise, warmer ocean temperature and increased of significant wave height are among a few example of what climate change may bring to Indonesia ocean environments. These problems should received serious attention from government to develop adaptation and mitigation plans for future developments.
