## 1 Introduction  
Climate can be defined as the expectation of the current and coming status of weather in an area over a certain time span. It is necessary to enable people to move from one area to another or even from one country to another with adequate knowledge regarding clothes or planning activities. Due to their regular weather patterns, some areas are classified as winter-activity locations, while others are classified as summer zones in relation to tourism. The primary data for such locations are the temperature and the average number of rainy days. However, climate expectation limits go beyond those data as many other aspects are important, not only for travel and tourism but also for preserving the assets of such heritage sites, which may comprise heritage assets classed as nonrenewable wealth. Many scientists have studied climate phenomena to predict those data, especially considering the rapid change in climate and its impacts. For heritage experts, those expectations are important for predicting hazards and applying preventive actions to protect heritage buildings. The impact of climate change is related to gas emissions, which cause changes in Earth's temperature. Thus, the term \"greenhouse gases\" has appeared to express changes in the atmosphere and in gas percentage and saturation. When the sun's rays travel to Earth, many are reflected in space, while land, seas, and oceans absorb the others. Earth's surface retains this heat. Without greenhouse gases such as carbon dioxide, methane, nitrous oxide, and water vapor, all the heat would take another path to space. Hence, the planet's average heat changes, as the role of greenhouse gases is to absorb the missed rays and reflect them to Earth. Those gases are the key to balancing the climate and controlling the change. Many concepts have been suggested to preserve Earth by reducing climate change impacts, such as green architecture, sustainability, and green heritage. Greenhouse gases keep Earth's surface warm. There are many products, named greenhouse windows, doors, etc., related to this concept whereby an element of the product keeps something warm. The concentration of greenhouse gases has been increased due to human activities such as burning fuels. In 1896, a Swedish scientist measured the warming that occurred as a result of CO\({}_{2}\) increase and predicted a warming level increase as a result. Fuel burning, the cement industry, and many other issues have caused an increase in CO\({}_{2}\) release to the atmosphere that is greater than that in the natural cycle. Many other factors are related to climate change, such as rising sea levels (which are one of the focuses of this research paper and represent the main problem for coastal heritage sites), precipitation, and others. However, the rising sea level is a hazard, as its extent is greater than expected due to the melting of sea and ocean ice. It is also evident in the hard waves that hit coastal areas, and it becomes more hazardous when the coastal area is a valuable nonrenewable heritage site or asset [1]. Heritage sites must be conserved against future development and its ramifications, as they cannot be maintained by passive conservation, but should be part of present and future development. Heritage sites are assets that should be dealt with wisely so they can be passed on to the next generation to start a new cycle of sustainability [2]. Many heritage sites face problems related to climate change. When the site is in a coastal area or even in the sea, these problems become serious as water levels and strong waves cause deterioration and erosion. In such cases, an active process to adapt to the change that may occur to the heritage site because of the sea is the only solution. This adaptation is expected to be flexible and cannot be strict due to the uniqueness of every heritage site. Thus, the resilience approach is important and should decide the extent of the solution to reduce the impact.
