Climate change, the effects of greenhouse effect and global warming, is out to alter the global map with its devouring prospects of sending a number of countries under the waves. Unfortunately yet unavoidably, Bangladesh stands at the forefront of climate forays. Its land, water and weather are being severely affected by undesirable climatic changes. Alarmingly, the dangers are to be intensified unless the trend is reversed. However, local initiative will hardly be enough to offset the grave concerns of unintended climatic changes in Bangladesh. The changes will also impact the socio-economic conditions of the country, putting the future of the nation on the line. Some ominous signs are already there for the concerned to respond with required amount of fervour.

Abstract In this study, high-resolution climate projections over Ontario, Canada, are developed through an ensemble modeling approach to provide reliable and ready-to-use climate scenarios for assessing plausible effects of future climatic changes at local scales. The Providing Regional Climates for Impacts Studies (PRECIS) regional modeling system is adopted to conduct ensemble simulations in a continuous run from 1950 to 2099, driven by the boundary conditions from a HadCM3-based perturbed physics ensemble. Simulations of temperature and precipitation for the baseline period are first compared to the observed values to validate the performance of the ensemble in capturing the current climatology over Ontario. Future projections for the 2030s, 2050s, and 2080s are then analyzed to help understand plausible changes in its local climate in response to global warming. The analysis indicates that there is likely to be an obvious warming trend with time over the entire province. The increase in average temperature is likely to be varying within [2.6, 2.7]°C in the 2030s, [4.0, 4.7]°C in the 2050s, and [5.9, 7.4]°C in the 2080s. Likewise, the annual total precipitation is projected to increase by [4.5, 7.1]% in the 2030s, [4.6, 10.2]% in the 2050s, and [3.2, 17.5]% in the 2080s. Furthermore, projections of rainfall intensity–duration–frequency (IDF) curves are developed to help understand the effects of global warming on extreme precipitation events. The results suggest that there is likely to be an overall increase in the intensity of rainfall storms. Finally, a data portal named Ontario Climate Change Data Portal (CCDP) is developed to ensure decision-makers and impact researchers have easy and intuitive access to the refined regional climate change scenarios.

Green building has become an important issue among architects and urban planners due to the increment in global warming risks and climatic changes which influenced negatively on natural resources. It is also one of measures been put forward to alleviate the significant impacts of the influence of buildings on the environment, society and economy. There have been extensive studies on green buildings, as evidenced in the rapid growing number of papers been published in last decades. These studies have been conducted in both developed countries and developing countries, indicating this is a global issue. However, there is lack of extensive researches on the green buildings in Iraq that is crucial for the future exerts. This paper reports the definition of green building, the environmental, social and economical aspects of green building, and application of green building's principles in traditional housing in Iraq.

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.

Environmental pollution states the toxification by different forms of pollutants in the surroundings. This causes the natural system imbalance and affects the life on earth in different ways. The emissions of pollutants into air result in climate changes. The rising levels of CO2 and other air-polluting gases increase the greenhouse effect which results in temperature elevations and affects global weather patterns. Bill Gates also warned “Climate change is a terrible problem, and it absolutely needs to be solved; it deserves to be a huge priority”. Though climate change and air pollution are closely linked, these are treated as separate problems. Hence, it is aimed to understand the aspects of association between climate change and air pollution in this chapter with the objectives: (i) To know the basics of climate change and air pollution, (ii) To review the active background studies on climate change as well as on air pollution, (iii) To identify the issues, controversies, problems which include the effects of global warming and greenhouse gases followed by the types of air pollutants and its harmful effects, (iv) To find the solutions and recommendations, the discussions are made on climate laws and policies, (v) To retrieve, analyze and store the climate change related information, the description about models, tools and databases are given, (vi) To have a flawless insights on the association of climate change and air pollution, (vii) To exemplify species indicators for the assessment of the effect of air pollution on climate change are also included. As Bernie Sanders said “Climate change is a planetary crisis. We've got to act, and we have to act boldly”.

<p>Under the current global warming trend, heatwaves are becoming more intense, frequent, and longer-lasting; and this trend will continue in the future. In this context, the recent 2019 summer was exceptionally hot in large areas of the Northern Hemisphere, with embedded heatwaves, as for example the June and July 2019 European events, redrawing the temperature record map in western Europe. Large-scale dynamics (associated with blockings or subtropical ridges) play a key role in explaining these-large scale events.</p><p>Conceptually, global warming can be split into two different contributions: Dynamic and thermodynamic changes. Whereas dynamic changes remain highly uncertain, some thermodynamic changes can be quantified with higher confidence. We exploit this concept by studying how these recent European heatwaves would have developed in a pre-industrial climate and how it would develop in the future for 1.5, 2 and 4 ºC warmer climates (storyline scenarios). To do so, we employ the spectral nudging technique with AWI-CM (CMIP6 model, a combination of ECHAM6 AGCM + FESOM Sea Ice-Ocean Model). Large-scale dynamics are prescribed by reanalysis data (ERA5). Meanwhile, the model is run for different boundary conditions corresponding to preindustrial and future climates along the SSP370 forcing scenario. This approach can be useful to help understand and communicate what climate change will mean to people’s life and hence facilitate effective decision-making regarding adaptation to climate change, as we are quantifying how recent outstanding events would be modified by our climate action. </p><p>Temperatures during the heatwaves often increase twice as much as global mean temperatures, especially in a future 4 ºC warmer climate. In this future climate, maximum temperatures can locally reach 50ºC in many western Europe countries. Nighttime temperatures would be similar to the daytime temperatures in a preindustrial world. The global warming amplification can be partly explained by a robust soil drying in the future 4 ºC warmer climate (exacerbated due to the June 2019 heatwave) which is transmitted to a robust increase in Bowen ratio. Importantly, by design of our study, this response occurs without any changes in atmospheric circulation.</p>

Abstract. In Paris, France, December 2015, the Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC) invited the Intergovernmental Panel on Climate Change (IPCC) to provide a special report in 2018 on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways. In Nairobi, Kenya, April 2016, the IPCC panel accepted the invitation. Here we describe the response devised within the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) to provide tailored, cross-sectorally consistent impact projections to broaden the scientific basis for the report. The simulation protocol is designed to allow for (1) separation of the impacts of historical warming starting from pre-industrial conditions from impacts of other drivers such as historical land-use changes (based on pre-industrial and historical impact model simulations); (2) quantification of the impacts of additional warming up to 1.5 °C, including a potential overshoot and long-term impacts up to 2299, and comparison to higher levels of global mean temperature change (based on the low-emissions Representative Concentration Pathway RCP2.6 and a no-mitigation pathway RCP6.0) with socio-economic conditions fixed at 2005 levels; and (3) assessment of the climate effects based on the same climate scenarios while accounting for simultaneous changes in socio-economic conditions following the middle-of-the-road Shared Socioeconomic Pathway (SSP2, Fricko et al., 2016) and in particular differential bioenergy requirements associated with the transformation of the energy system to comply with RCP2.6 compared to RCP6.0. With the aim of providing the scientific basis for an aggregation of impacts across sectors and analysis of cross-sectoral interactions that may dampen or amplify sectoral impacts, the protocol is designed to facilitate consistent impact projections from a range of impact models across different sectors (global and regional hydrology, lakes, global crops, global vegetation, regional forests, global and regional marine ecosystems and fisheries, global and regional coastal infrastructure, energy supply and demand, temperature-related mortality, and global terrestrial biodiversity).
