The Problem Of Global Warming

Evidence of Climate Change is being felt around the world. The most vulnerable areas are the least developed, which lack public instruments and infrastructure to adapt to the extreme effects of climate. Reducing greenhouse gas emissions is vital to slow the progress of climate change, however, adapting to the consequences of this intensified climate crisis by the human being itself is key. Some countries understand it, others just cannot do too much about it. New evidence shows that Climate Change has affected many sectors in Asia. Crop yields in several countries have declined, due in part to increased temperature and external weather events. The retreat of glaciers and permafrost in Asia in recent years has no precedent and is a consequence

Climate change has the potential to transform food production, especially the patterns and productivity of crops, livestock, and fishery systems; and to reconfigure food distribution, markets, and access (Nelson et al., 2009). Chen et al. (2012) observed that climate change has already had a negative impact on Asia through extreme temperatures, frequent flooding and droughts, sea level rise, and increased salinity of water supplies for rainfed agricultural areas. Most Asian countries are quite dependent on their domestic supplies of rice. The International Rice Commission (2003) indicates that Bangladesh, China, India, Indonesia, and Vietnam are the major producers of rice, producing more than 70% of the world’s volume. The Asian rice-producing countries tend to consume most of their domestic rice production. Nevertheless, Thailand and Vietnam are able to export some rice to neighboring countries such as Bangladesh, Indonesia, and the Philippines. Dasgupta et al. (2009) identified ten developing countries whose land areas are most exposed to the potential threat of a one-meter rise in sea level. Among the countries most affected by sea level rise are Bangladesh, China, Taiwan, and Vietnam and these are all rice-growing and rice-consuming countries. Using a partial equilibrium global rice trade model, Chen et al. (2012) investigated the potential impact of sea level rise combined with climate-induced crop yield change on global rice

The first part of the research provides background information on what climate change is, what are its most important constituent elements, and what are its implications. Climate change represents in essence a global challenge that can only be tackled at the global level. This is why it is important to consider the views and perspectives of global organizations such as the United Nations, through the United Nations Environment Program among other organisms under the coordination of the United Nations. Climate change has been at the center of vivid debates in recent decades particularly because it affects all strata of human life, from food supplies to education, health, and sustainable development. Its complex impact on human life makes climate change an all the more important aspect to be taken into account by policy makers, world leaders, and decision takers around the world.

This global organization is called the Intergovernmental Panel on Climate Change. This world-wide collaboration of specialists were to compile scientific reports from across the globe and issue reports regarding the impacts of global climate change internationally and its impacts upon an array of ethnic groups. These reports include scientific and socio-economic data measuring both technical details as well as the effect local weather patterns have made on droughts, flooding, wild and domestic livestock, water supplies, and the all-important food production. The five reports the IPCC has issued to date show a strong correlation between greenhouse gases and global warming, and strongly state that climate change is causing severe changes in weather patterns with catastrophic result. The most recent report was released in March this year (Howard).

For the past years, global warming and climate change became important issues of science and the environment. However, with the realization of the possible threats it poses to humankind in general, global warming gained international significance. Climate change is a global problem that requires a global response embracing the needs and interests of all countries (Boer, 2008). Countries around the world, convinced by the threats of the global warming, choose to act hand-in-hand to face to the issue.

It is a known fact that climate change has the potential to damage human development across many countries, including India. India is confronted with increased global climate change threat amidst the challenge of sustaining rapid economic growth. Evidences have shown that climate change not only affects the quality and distribution of India’s natural resources, but also ultimately threatens the livelihoods of the most poor and marginalised sector that are closely attached to India’s natural resources for their daily needs and development as half of the population are engaged in agriculture and allied sectors2. While developing countries like India are responsible

Water is a natural resource of planet Earth, and affects all natural, social and economic systems. As recognized by the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) in 2007, observational evidence from all continents and most oceans shows that many natural systems, on which the hydrological cycle and therefore water availability, water quality, and water services depend, are affected by changing climate. As a result, this will also have major effects on human security and sustainable development.

Climate change, a problem affecting many things, is affecting everyone, even if you do not notice it directly. That is when it can hurt the most. It is affecting agriculture all around the world which means, our food sources, economy, and many other important parts of life are feeling the effect of climate change. From what we know today, Africa, Latin America, and South Asia together, in 2011, accounted for approximately ninety-five percent of the world’s agricultural population. Other places, however, in Northern European, Asian, and American countries, agricultural productivity many even temporarily increase. This can increase because rising CO2 levels can stimulate plant growth, although, this can decrease nutritional value.

It is terrible that climate change has affected every country. As a result, one key information that we think will help us make a better analysis will be each country's progress in dealing with the issue. This information can be found in recent news and articles that give detail reports on the topic. One can also learn more from scientific documents written by ecologists that currently research on climate change. Moreover, one can monitor the daily temperature of a specific season, summer for instance, in the countries for a few years. From this point, one can calculate the average temperature per summer and see which country had the most increase or decrease in terms of these average temperatures. The country that experiences the least increase

Population growth and its effects on climate change have been hotly debated in recent years by scientists and politicians alike. The Fourth Assessment Report of the IPCC has sparked great interest and concern over climate change and how it affects countries differently. The concept of environmental justice has focused on climate change’s unbalanced effects on developing countries, whose populations are more vulnerable to climate change. With rapidly growing populations and inadequate resources and technologies, developing countries have struggled to develop their economy sustainability. The relationship between population and climate change is grossly oversimplified by the idea that as population increase so does its effect on climate change. Realistically, population and climate change affect each other through economic trends, development patterns, society, institutions and the government. Population dynamics is not simply the number of people in a given space. Rather, it is the distribution and continuously changing demographics that make population dynamics a complex but important factor in climate change policy. In recent climate change and environmental protection discussions, developed countries have strongly suggested or even imposed environmental policies upon developing countries. This has caused tension and misunderstandings on both sides as developing countries strive for the economic success of their

Although a number of studies have previously been conducted in Bangladesh to investigate the effect of increased temperature and CO2 concentration on rice cultivars (Karim et al. 1994; Mahmood 1998; Mahmood et al. 2004), but less attention has been devoted to modeling studies for rice production (Basak et al. 2010; Karim et al. 2012). Most of the previous studies did not address the effects of climate warming with and without CO2 fertilization under the simulation schemes of different regions in Bangladesh. However, it is yet to find any study which focuses on the regional spatiotemporal yield variations of rice and potential adaptation strategies under future climate change in Bangladesh. Spatiotemporal yield variation studies are essential to identify

The issue of global warming should be on the list of our top priorities. Studies show that the average of global temperatures have risen since the Industrial Revolution began. Since the Industrial Revolution, human emissions has quadrupled the frequency of certain heat extremes and many scientists have warned that a failure to bring greenhouse gases under control could eventually lead to a 62-fold increase in extreme heat blasts (Gillis Justin A17). Most of the increase is due to human activities, especially the burning of fossil fuels and deforestation. These activities contribute to a build-up in carbon dioxide and other gases in Earth’s atmosphere. The Earth’s atmosphere is made of gases like nitrogen, carbon dioxide and oxygen. These gases act as a blanket that covers and gives us warmth, but once these gases such as carbon dioxide absorbs heat, but does not release it back into space in which causes the increase in global temperature. This is called the greenhouse effect because it only traps heat but does not release it.

Bangladesh stands among the frontline countries confronted by the impacts of climate change. For several decades we have been experiencing the gradual increase, frequency and erratic pattern of floods, river erosion, cyclones, earthquake murmurs, tidal bores, encroachment of salinity in the low lying coastal

adaptations to climate change, in 2010, the World Bank estimated the costs of adaptation to climate change by 2050. These costs will reach $6.59billion by 2030. Additionally, it was estimated that Bangladesh will have to invest $40 billion from 2015 to 2030 “in order to implement identified adaptation measures” (INDC, 2015).

Bangladesh is one of the least developed countries with a low resource base, a burgeoning population with a very low land-man ratio, often threatened by both natural & anthropogenic stresses. The vast majority of the population lives almost exclusively on the natural resource base. This resource base is under serious threat and environmental planning is essential for the survival with dignity for Bangladesh’s over 115 million people & for sustainability of the echo system.
