Various other models predict the nation's vulnerability. Bangladesh is the nation most vulnerable to global climate change in the world, according to German Watch’s Global Climate Risk Index (CRI) of 2011. This is based on the analysis of impacts of major climate events that occurred around the world in the twenty-year period since 1990. The reasons are complex and extremely intertwined.
Located at the bottom of the mighty GBM river system (comprising the Ganges, the Brahmaputra and the Meghna), Bangladesh is watered by a total of 57 trans-boundary rivers coming down to it: 54 from neighbouring India and 3 from Myanmar. The country, which has no control of the water flow and volume, drains to the Bay of Bengal over 90% of the total run-off generated annually. Coupled with the high level of widespread poverty and increasing population density, limited adaptive capacity and poorly funded, ineffective local governance have made the region one of the most adversely affected in the planet. There are an estimated one thousand people in each square kilometre, with the national population increasing by 2 million people each year. Almost half the population is in poverty (Purchasing Power Parity of $1.25 per person a day). Hence these people do not have the ability to respond to a natural disaster and the government cannot help them.[2]
Effects[edit]
It is projected that, by 2020, from 500 to 750 million people will be affected by water stress caused by climate change around the world. Low-lying coastal regions, such as Bangladesh, are vulnerable to sea level rise and increased occurrence of intense, extreme weather conditions such as the cyclones from 2007–2009. In most countries like Bangladesh, yields from rainfed agriculture could be reduced to 50% by 2020. For a country with increasing population and hunger, this will have an extremely adverse effect on food security. Although effects of climate change are highly variable, by 2030, South Asia could lose 10% of riceand maize yields, while neighbouring states like Pakistan could experience a 50% reduction in crop yield.
As a result of all this, Bangladesh would need to prepare for long-term adaptation, which could be as drastic as changed sowing dates due to seasonal variations, introducing different varieties and species, to practising novel water supply and irrigationsystems. In essence, we have to identify all present vulnerabilities and future opportunities, adjusting priorities, at times even changing commodity and trade policies in the agricultural sector while promoting training and education throughout the masses in all possible spheres.[3]

...CLIMATE CHANGE ADAPTATION PROJECT Climate change is the change in stable weather conditions of a given place which have been noted in such a place for a period extending over thirty years. It is notable and lasting change in the distribution of weather patterns in over thirty years. Climate affects agricultural production directly. The International Fund for Agricultural Development accepts climate change to be among the factors influencing rural poverty. Climate change affects the globe as a whole but its effects is felt much more by poor people in third world countries because they rely much on natural resources as a source of their livelihoods. Poor rural communities rely much on livestock keeping and agriculture which are climate-sensitive sectors of the economy. We have to adapt and employ mitigation strategies to respond to climate change. Adapting involves reducing the vulnerabilities of ecosystem to climate change whereas mitigation involves reducing the long term impact of climate change. Mitigating also involves reducing the emission of green house gases while adapting will also involves supporting local communities to deal with the impacts of climate. Agriculture of a given place depends on the climate of such a place; with climate change agriculture is affected negatively. Climate change accelerates the challenges facing the agricultural production and specifically in Sub-Saharan Africa. Innovations are the way to mitigating the effects of climate change on......

...Peoples Attitudes towards Climate Change A group paper is presented to the faculty of Mindanao University of Science and Technology – Jasaan Campus presented by Steven Castino, Geneth Caturan, Marjohn Deleon, John Henry Mercado, Julan Aricayos, Kimbert Pacana, Joseph Sumayang, June Rey Tarpin, Richard Nacua, Joel Cabelto, and Rey Carlou Cailing. I. Introduction Climate Change or Global warming is the increase of the average temperature of earth’s atmosphere, oceans, and landmasses. Scientists believe earth is currently facing a period of rapid warming brought on by rising levels of heat-trapping gases, known as greenhouse gases, in the atmosphere (Harvey, 2012). Ironically, “It is not climate change that is our problem, but the attitude of people that should be addressing the problem” (Fernandez, 2012). Most previous studies evaluating the cause of awareness to the people towards the climate change is the effects of people’s attitude towards climate change (Gallup, 2008; Barret & Dannenberg, 2012). Most of the studies confirm the explicit and implicit attitudes towards climate change suggest targeting hidden thoughts a better way to change people’s behavior (Corner, 2010; Kormos & McIntyre, 2011). There are also findings that proved the countries to firm one another to build human activities towards climate change. This paper is intended to transport cognizance on the necessary ideas on what are the people’s perception towards climate change that have been......

...CLIMATE CHANGING AND THE EFFECT IT HAS ON YOU Dijonne King PSC 140 December 1, 2013 Climate change is the climate patterns attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. Climate change has recently become a huge issue here on Earth. The use of fossil fuels has largely affected the world as we see it today. Temperatures are rising, snow and rainfall patterns are shifting and extreme climate events such as heavy rainstorms and record high temperatures are highly affecting our environment. Through evidence of this climate change, scientists have come to realize the causes and effects of climate change. Through learning about what creates climate change, learning how climate change impacts you, and taking action, I believe climate change can definitely have a positive impact on everyone. Through scientific evident it is clear that climate change has affected the planet Earth as we know it. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. The average temperature at the surface of the Earth has been increasing over the past century, mostly due to human activities. Warmer surface temperatures lead to increasing evaporation from the ocean and land, leading to an increase in global precipitation. Scientific studies have shown that extreme weather is more likely to become more intense with time. Human activities......

...Most of the scientists agree that this climate change is threatening our earth; human beings can be extinct probably in the near future. The cause and effects of this phenomenon has been studied which is greenhouse effect. The whole world is getting involved in this issue and looking for solutions. Greenhouse effect is a natural phenomenon that increases temperature of the earth’s surface (Australian government). However, according to the investigations, human activities enhanced the greenhouse activities, making it worse. So our climate change is due to the increasing human activities, global industrialization which ejects huge amount of carbon emissions. Human activities enhance greenhouse effect that causes widespread heave rainfalls in the northern Hemisphere during the last 50 years (Minetal, as cited in Allan, 2011).The rising temperature is disrupting every aspect in our life and the whole ecosystem. This climate change affects atmospheric and ocean circulations and brings many hazards to the earth, such as widespread drought, flood and tsunami. As we considered climate change, we need consider the common good for all the humans on the earth. The common good refers to the total living conditions which can enable individuals to get the achievement which enables people to achieve humanity (google), whereas climate change is a serious issue that is eliminating human living resouces in many aspects. As we mentioned above, climate change can cause many negative effects,......

...Climate change Global warming , the definition is the increase in the earth’s ocean and near surface temperatures. In the last decades, there have been many debates about global warming. Greenhouse gases contribute to the climate changes, greenhouses gases is carbon dioxide, but there is an ongoing debate if natural sources, such as volcanoes, and forest fires contribute to the climate changes. The United Nations Framework Convention on Climate Change (UNFCCC) created the Kyoto protocol, is an agreement among industrialized nations who have pledge to reduce their annual emission of greenhouse gasses. The kyoto protocol currently consist of over 160 nations over 55% of the worlds greenhouse gasses. The biggest contributor of the greengasses, made more than 20.6% of the world greenhouse gasses, that nation is the United States. Barack Obama , the president of U.S has created the Clean Energy Act. The CEA serve to reduce our dependence on fossil fuel. Other governments have imposed a tax on carbon emission to encourage using clean energy. Global warming is no longer fiction, scientific studies have proved that earth is undergoing a period of rapid change. The Intergovernmental Panel on Climate Change (IPCC) claims that the average global temperature has increase .74C. Our high dependence on fossil fuels as source of energy has raised the atmospheric content of greenhouses gasses levels which are higher than almost any point in history. The biggest danger with global warming is......

...Every place, country, city, region has its own climate. Climate plays one of the important roles in people’s life. Climate is defined as the average weather, which means variety of weather conditions as rain, snow, hail, sun, and wind over period of time about 30 years that can be measured in any particular place.( IPCC Third Assessment Report - Climate Change 2001; editor:A.P.Baede) Climate change is a variation of average weather. There are 2 causes of climate change. The first is human activity which includes deforestation, burning fossil fuels, agriculture, transportation and infrastructure. The second is natural causes which include volcanic eruptions and variations in solar outputs. These causes have negative effect on the natural environment which leads to increasing of temperature, increasing in sea level, changing of precipitations, extremely weather, killing species of animals, birds, fish and plants. This essay will show that the causes of climate change have different effects on the environment. Atmospheric carbon dioxide variations, volcanic eruptions and solar outputs, have negative impacts on animals, plants, and environment. Climate is always changeable. One winter can be early, another late; one summer wet, another dry (Carter 2000,34). For the last century climate has dramatically changed. Consequences of climate change may manifest itself as rapid and through the long period of time. Climate change could lead to number of catastrophic disasters as......

Climate Change

...The Earth’s climate is changing. Temperatures are rising, snow and rainfall patterns are shifting, and more extreme climate events—like heavy rainstorms and record high temperatures—are already taking place. Scientists are highly confident that many of these observed changes can be linked to the climbing levels of carbon dioxide and other greenhouse gases in our atmosphere, which are caused by human activities. There are a number of different forces which can influence the Earth's climate. When the sun gets brighter, the planet receives more energy and warms. When volcanoes erupt, they emit particles into the atmosphere which reflect sunlight, and the planet cools. When there are more greenhouse gases in the atmosphere, the planet warms. These effects are referred to as external forcings because by changing the planet's energy balance, they force climate to change. It is obviously true that past climate change was caused by natural forcings. However, to argue that this means we can't cause climate change is like arguing that humans can't start bushfires because in the past they've happened naturally. Greenhouse gas increases have caused climate change many times in Earth's history, and we are now adding greenhouse gases to the atmosphere at a increasingly rapid rate. Looking at the past gives us insight into how our climate responds to external forcings. Using ice cores, for instance, we can work out the degree of past temperature change, the level of solar activity,......

... Impacts Of Climate Change IN Bangladesh | Group 2 | Members-Sakib Shahriar-1510119630 | Israt Jahan-1510581630 | Joyeeta Fabliha Zahir-Faisal Ahmed Shajal-Ashrafun Zamam Lima-Kazi Pushpita- | | Faculty-MRL ENV-107 | [Pick the date] | | Abstract Climate change is one of the most important issues to tackle this generation and possibly any generation in history. Bangladesh is likely to be one of the most vulnerable countries in the world to climate change. This paper discusses the possible impacts of climate change in Bangladesh through tropical cyclones, storm surges, coastal erosion and back water effect. Both qualitative and quantitative discussions are made on cyclone intensity increase for a sea surface temperature rise of 2 and 4°C. Different scenarios of storm surges under different climate change conditions are developed by using a numerical model of storm surges for the Bay of Bengal. Possible loss of land through beach erosion due to sea level rise on the eastern coast of Bangladesh is examined. Finally a few remarks are made on the adaptation options for Bangladesh in the event of climate change. Introduction Climate change is the biggest global health threat of the 21st century and is increasingly recognized as a public health priority. Bangladesh is recognized as one of the most vulnerable countries to climate change impacts in the world. It has a history of extreme climatic events claiming millions......

...Climate Change: Is Global Warming To Blame? Climate change is a serious reason for concern, because it affects every person living on the planet. The vast majority of the scientific community claims that anthropogenic global warming is to blame for these changes. However, there are a small number of people who deny the very existence of global warming. Their words carry a certain amount of weight in some circles, but they lack scientific proof to support these arguments. The effects of climate change are undeniable. Research conducted by the Intergovernmental Panel on Climate Change (IPCC) and other reputed meteorological institutions proves that average yearly temperature has been steadily growing over the last decades. The sea levels have also been rising, and the number of floods in different parts of the world has increased dramatically. Glaciers in the Northern Hemisphere have started to melt. This caused more icebergs to drift into the ocean. They currently pose a serious threat to both, cruise and cargo ships that course through the waters of the northern regions. There are reports of some icebergs being spotted far to the South from Greenland. Over 95% of scientists agree that these changes are caused by the “greenhouse effect”. There is some solid evidence which proves that people are directly responsible for the global warming that is fueling this climate change. Destruction of forests, burning of fossil fuels and environmental pollution are the main......

... Climate change becomes a universal issue in recent years, with the negative influence occurring in the third world. There are lots of negative effects on most urban areas city on coast and riverbanks are vulnerable to climate change effects such as a increase in sea level (Nichcolls, cited in Hunt and Watkiss 2004, p.17). Climate change refers to any change in climate over time, whether due to natural variability or as a result of human activity (Parry M.L et al. 2007, p.13). The world’s urban population will rapid increase in the next few year, so the negative effects caused by climate change in cities should be solved necessarily. This essay outlines the major negative impacts by climate change, and evaluates three possible solving measures in many developing countries. The essay argues that three effective solutions are able to solve the problems of climate change in developing countries. Climate change negatively affects the urban in developing countries. The first environmental effect of climate change is a rising sea level. Rosenzweig et al. (2010, p.910) survey that city should obviously contributed to 71% of global energy-related greenhouse-gas. Most chief cities in developing country are located in low altitudes or near the seaside, which are brought calamities by the climate change. As the world warming, the threat from the ocean level increase poses alarming for cities. A rising in sea level has the direct influences on urban areas such as beach erosion and......

...Climate change has damage the planet beyond repair. Melissa Giannotti (1100 words) ‘Unless we announce a disasters, no one will listen’ (J.Houghton, 1994). The continuous struggle to halt climate change and save the world is perhaps the biggest challenge the humanity has ever faced. The world-threatening rise in temperatures, the extinction of species and the flooding of oceans, is coming under challenge as never before. The world has known about global warming since the late 1970s, but since that time a little has been done to halt it. This essay sets out to examine why is too late to find a solution to save the planet. The first thing to get straight is to define the meaning of climate change. Climate change involves any changes in weather patterns, such as colder, wetter, cloudier, and windier condition. According to McGuire (2008,a), over the 4.6 billion year history of our planet, the climate has constantly changed in response to several factors. Until now, many have argued that since the industrialization has started, more greenhouses have been added to the atmosphere, causing the warming Earth’s climate. In fact, research conducted by the Intergovernmental Panel on Climate Change (IPCC, 2013) states that the warming of the climate system is certain. Each of the last three decades has been successively warmer than any previous decade since the 1850. For instance, the evidence demonstrate a clear increase in warming of 0.85 [0.65 to1.06]°C over the period 1880 to......

As our course teacher selected the topics “Climate Change and Bangladesh”. Accordingly we have to write on this topic. Climate change is a long-term change in the statistical distribution of weather patterns over periods of time that range from decades to millions of years. It may be a change in the average weather conditions or a change in the distribution of weather events with respect to an average, for example, greater or fewer extreme weather events. Climate change may be limited to a specific region, or may occur across the whole Earth. In recent usage, especially in the context of environmental policy, climate change usually refers to changes in modern climate. It may be qualified as anthropogenic climate change, more generally known as global warming or anthropogenic global warming Bangladesh is frequently cited as one of the most vulnerable countries to climate change because of its disadvantageous geographic location, flat and low-lying......

Impact and Adaptation to Climate Change in Bangladesh

...IPCC, South Asia is the most vulnerable region of the world to climate change impacts (McCarthy et al., 2001). The international community also recognizes that Bangladesh ranks high in the list of most vulnerable countries on earth. Bangladesh’s high vulnerability to climate change is due to a number of hydro-geological and socio-economic factors that include: its geographical location in South Asia; its flat deltaic topography with very low elevation; its extreme climate variability that is governed by monsoon and which results in acute water distribution over space and time; its high population density and poverty incidence; and its majority of population being dependent on crop agriculture which is highly influenced by climate variability and change. Despite the recent strides towards achieving sustainable development, Bangladesh’s potential to sustain its development is faced with significant challenges posed by climate change (Ahmed and Haque, 2002). It is therefore of utmost importance to understand its vulnerability in terms of population and sectors at risk and its potential for adaptation to climate change. Increased climate variability means additional threats to drought-prone environments and is considered a major crop production risk factor. The impact of climate variability and change on agricultural production is a global concern. However, the impact is particularly important in Bangladesh where agriculture is the largest sector of economy,......
