‘Evidence for climate change’ considers both past and recent climate change through changes in temperature, precipitation, and relative global sea level to show that significant changes in climate have been recorded. These include a 0.85°Celsius (C) increase in average global temperatures over the last 150 years, sea-level rise of over 20 cm, significant shifts in the seasonality and intensities of precipitation, changing weather patterns, and significant retreat of Arctic sea ice and nearly all continental glaciers. The IPCC 2013 report states that the evidence for global warming is unequivocal and that there is very high confidence that this warming is due to human emissions of greenhouse gases.

Climate-Change (Global warming) is the central point on the current agenda of the international environmental policy. This paper proposes a model to formulate the global warming policy as dynamic Stackelberg or Leader-Follower Game. In this game, an international agency or international agreement is the leader, who will decide the emission abatement rate of each region; and the followers are several regions who control their consumption of carbon-energy relating to carbon emissions. The challenge of this model is to solve its equilibrium since it is not a liner-quadratic game model.

Millennials have been touted as the generation that will do something about global warming. Conversely, some social scientists studying generational differences have found evidence that younger generations are less likely to engage in civic matters like environmental activism. Lack of civic engagement among Millennials may reduce their likelihood of engaging in collective action on global warming. On the other hand, the world is drastically changing. Within the recent years, climate change has become a growing concern worldwide. The various modes of destruction imposed on the environment are targeted to be the catalyst to these changes. According to climate scientists, sea level rise is one of the most important impacts of global climate change. Fishermen as one of the professions that depend their life on the sea, is affected so much by this condition. This condition might destroy their houses on the coastal area. Urban Kampong in Jakarta as the most dense human settlements in urban area has become one of the main economic generator for a city. With all the contradict characteristics and forms, urban kampongs are the part of the city that cannot be separated from one to another. The existence of kampong has become the main embryo of the development of Jakarta. Jakarta is one of the biggest coastal city in the world. The coastline of this city has become the main economic generator for the coty and the nations. The existence of fishermen’s kampong in Jakarta has also become an essential program for the city, in order to fullfill the needs of fresh catch of sea products. Therefore, The project is aimed to create a sustainable and adaptive coastal kampong community, that has the resilience to the rising sea level. By concerning on the kampong’s behaviour, and doing research of the typological transformation of the kampong, the design is also expected to serve as an archetype fot the future development of endagered coastal settlements all across the country. several sustainable approach and behaviourial approach are also injected in this project to create a contextual design that would help the kampong to grow, and adapt to all the conditions, and situation in the future. AbstrakGenerasi milenial dianggap sebagai generasi yang akan melakukan perubahan nyata terkait dengan pemanasan global. Akan tetapi, beberapa studi pun menunjukan bukti bahwa generasi millenial justru memiliki kesadaran serta kepekaan yang tidak lebih tinggi dibandingkan dengan generas-generasi sebelumnya. Pada satu sisi, bumi kian melakukan perubahan yang begitu derastis. Berbagai macam kerusakan pun terjadi dalam berbagai jenis yang menjadi generator dari perubahan iklim yang drastis ini. Nelayan sebagai salah satu profesi yang menggantungkan nasibnya pada lautan, kian terganggu dengan kondisi ini. Hal ini menyebabkan kerusakan pada rumah-rumah di kawasan pesisir pantai. Kampung kota di Jakarta, sebagai permukiman terpadat di daerah urban menjadi salah satu kenerator utama pada suatu kota. Dengan segala karakteristiknya yang berbanding terbalik dengan perkotaan, kampung kota merupakan bagian yang tidak dapat dipisahkan dari suatu kota. Eksistensi suatu kampung telah menjadi embrio dari perkembangan kota Jakarta. Jakarta merupakan salah satu kota pesisir terbesar di dunia. Daerah pesisir dari kota ini telah menjadi generator ekonomi utama dari kota itu sendiri dan juga nasional. Keberadaan kampung nelayan di Jakarta pun menjadi salah satu program penting yang perlu mendapatkan perhatian. Maka dari itu, proyek ini bertujuan untuk menciptakan suatu komunitas kampung pesisir yang berkelanjutan, adaptif serta memiliki ketahanan terhadap kenaikan permukaan air laut yang terjadi. Metode perancangan pada proyek ini dibagi menjadi 2 bagian utama yaitu analisis mikro yang membahas mengenai tipe dan perilaku, serta analisis makro yang membahas proyek dari segi perancangan urban. Dengan menitik beratkan pada studi perilaku, dan melakukan riset mendalam terhadap transformasi tipologi yang terjadi pada kampung, desain ini diharapkan dapat menjadi suatu arketipe untuk pengembangan kampung di daerah pesisir di masa depan di seluruh Indonesia. Sehingga dapat disimpulkan, bahwa dengan adaptasi tipe, perilaku serta sistem berkelanjutan yang sesuai dan tepat, desain dari kampung nelayan berkelanjutan ini dapat menjadi suatu respon yang tepat dalam menjawab permasalahan yang terjadi di kampung-kampung pesisir.

Fast urbanization produces a large and growing population in coastal areas. However, the increasing rise in sea levels, one of the most impacts of global warming, makes coastal communities much more vulnerable to flooding than before. While most existing work focuses on understanding the large-scale impacts of sea-level rise, this paper investigates parcel-level property impacts, using a specific coastal city, Tampa, Florida, USA, as an empirical study. This research adopts a spatial-temporal analysis method to identify locations of flooded properties and their costs over a future period. A corrected sea-level rise model based on satellite altimeter data is first used to predict future global mean sea levels. Based on high-resolution LiDAR digital elevation data and property maps, properties to be flooded are identified to evaluate property damage cost. This empirical analysis provides deep understanding of potential flooding risks for individual properties with detailed spatial information, including residential, commercial, industrial, agriculture, and governmental buildings, at a fine spatial scale under three different levels of global warming. The flooded property maps not only help residents to choose location of their properties, but also enable local governments to prevent potential sea-level rising risks for better urban planning. Both spatial and temporal analyses can be easily applied by researchers or governments to other coastal cities for sea-level rise- and climate change-related urban planning and management.


Subject The prospects for global climate governance in 2018. Significance The 2017 UN COP23 Climate Change Conference, chaired by Fiji, ended in the shadow of news that 2017 is expected to see a 2% rise in global carbon emissions. After three years of roughly stable emissions, this estimated increase magnifies the challenge of making the sharp emission reductions needed to meet the Paris Agreement’s goal of keeping global warming to below 2 degrees centigrade above preindustrial levels, even as the renewable energy sector grows and electric vehicle technology makes further progress.


Subject Carbon transitions. Significance The EU in May failed to reach an agreement on how to achieve a long-term strategy on reducing carbon emissions. One of the issues underlying the persistent differences among member states was the question of how to achieve a ‘just transition’. This is becoming an increasingly significant element of national and international debates on tackling climate change. Impacts The International Labour Organisation believes a transition limiting heat rises to 2 degrees by 2030 would create 24 million jobs globally. Global coal production may stabilise as reductions in developed economies are offset by increases in Asia. The UK Treasury estimates that achieving carbon neutrality by 2050 will cost 1 trillion pounds (1.26 trillion dollars).

Climate change caused due to our careless activities towards our nature, ecosystem, and whole earth system. We are paying and will be paying in future for our irresponsible activities in past and present. Increased concentration of Green House Gases (GHG) has caused severe global warming which will cause melting of glacier and results in sea level rise. To avoid and reduce the intensity and severity of global warming and climate change, its mitigation is essential. In this chapter we have focused on various issues related with climate change and mitigation strategies.

Abstract The threat of dangerous climate change from anthropogenic global warming has decreased. Global temperature rose from 1975 to 1998, but since then has levelled off. Sea level is now rising at about 1.5mm per year based on tide gauges, and satellite data suggests it may even be falling. Coral islands once allegedly threatened by drowning have actually increased in area. Ice caps cannot possibly slide into the sea (the alarmist model) because they occupy kilometres-deep basins extending below sea level. Deep ice cores show a succession of annual layers of snow accumulation back to 760,000 years and in all that time never melted, despite times when the temperature was higher than it is today. Sea ice shows no change in 30 years in the Arctic. Emphasis on the greenhouse effect stresses radiation and usually leads to neglect of important factors like convection. Water is the main greenhouse gas. The CO2 in the ocean and the atmosphere are in equilibrium: if we could remove CO2 from the atmosphere the ocean would give out more to restore the balance. Increasing CO2 might make the ocean less alkaline but never acid. The sun is now seen as the major control of climate, but not through greenhouse gases. There is a very good correlation of sunspots and climate. Solar cycles provide a basis for prediction. Solar Cycle 24 has started and we can expect serious cooling. Many think that political decisions about climate are based on scientific predictions but what politicians get are projections based on computer models. The UN’s main adviser, the IPCC, uses adjusted data for the input, their models and codes remain secret, and they do not accept responsibility for their projections.

AbstractChina has announced its goal of reaching carbon neutrality before 2060, which will be challenging because the country is still on a path towards peak carbon emissions in approximately 2030. Carbon emissions in China did decline from 2013 to 2016, following a continuous increase since the turn of the century. Here we evaluate regional efforts and motivations in promoting carbon emission reduction during this period. Based on a climate change mitigation index, we pinpoint the leading and lagging provinces in emission reduction. The results show that achievements in industrial transition and non-fossil fuel development determined the leading provinces. Thus, the recommended solution for carbon neutrality in China is to promote the transformation of industrial structure and energy mix. In addition, policymakers should be alert to the path of energy outsourcing to reduce carbon emissions. Consumption-based emissions accounting and interregional cooperation are suggested to motivate developed regions to take more responsibility for climate change mitigation.

Climate change resulting from global warming has an increasing impact on Earth. The resulting sea level rise is starting to be noticed in some regions today, and based on projections, could have severe consequences in the future. These consequences would primarily be felt by residents of coastal areas, but through the potential for irreparable damage to cultural heritage sites, could be significant for the general public. The primary aim of the research undertaken in this article was to assess the threat to cultural heritage objects on the case study area of Tri-City, Poland. A review of available elevation data sources for their potential use in analyses of sea level changes was required. The selection of the optimal data source for the cultural heritage threat analysis of historic sites was carried out. The analyses were conducted for three scenarios, using ArcGIS Pro 2.7 software. A series of maps were thus prepared to show the threats to specific historic sites for various global sea level rise scenarios. Even with the slightest rise in sea level, monuments could be permanently lost. The authors point out that a lack of action to stop climate change could result not only in economic but also cultural losses.
