The Effect Climate Change has on a Species
As Earth’s climate cycles between warm and cool periods, species often must move to stay within suitable conditions. Scientists have now mapped how fast species have had to migrate in the past to keep up with changing climate. They found that small-ranged species – which constitute much of Earth’s biodiversity – are concentrated in regions where little migration has been required (Science daily). With people activities and habits, are changing their climates at an extremely fast past. What happens if a species cannot migrate as fast as it must to keep up with the velocity of climate change? Its range may shrink and, in some cases, the species may go extinct (Science daily).
This research provides the first evidence that past regional climate shifts interact with local topography and species dispersal abilities with long-lasting important consequences for the global distribution of biodiversity (Science daily). Earth’s climate 21,000 years ago was much colder than it is today, this caused many of the species that are still found today to occupy different areas than they do now. In northern Europe, for example, many of the species found today are relatively recent arrivals from their refuges in southern Europe (Science daily).
Many regions to include most of Africa and parts of the Amazon are going some of the leading places that are going through the most increased climate-change. These areas are expected to increase extremely rapid over the next 70 years. These areas, by virtue of their historically low velocities, have high concentrations of small-ranged species. These species will likely be at particular risk as velocities increase over the next several decades (Science daily). A team of ecologists and computer scientists have asked how fast species around the world have had to migrate to…...

Climate Change

...Climate Change Climate change is a long-term alteration in the statistical distribution of weather pattern over periods ranging from decades to millions of years. The world is currently experiencing drastic change in temperature. This change can be felt in the tropical climate areas where the weather is getting hotter and hotter every day. The change in global temperatures and precipitation over time is due to natural variability or to human activity. It is also caused by accumulation of greenhouse effects (Arrhenius, 1896). Should we as humans let this problem worsen? Climate change will affect everything including humans, flora and fauna, and the environment. One of the effects of climate change is how it will affect the people. Climate change will have a huge impact on the people’s health. The health of the people will be affected mostly by air pollution and respiratory problems will have the greatest risk of health effects. Increases in moulds and pollens due to warmer temperatures could also cause respiratory problems such as asthma for some people. Should the effects of climate change get any worse than what it is now, people around the world will have to face some serious problems. Food security will be affected and thus diseases can easily get transmitted. Food or waterborne diseases are acquired through eating or drinking. For example, Hepatitis A is a viral disease that interferes with the functioning of the liver. It can be spread through consumption of food or......

Climate Change and Its Effects on Accounting Practices

...Climate Change and its Effects on Accounting Practices William Conder Accounting 5233 November 26, 2013 Abstract in Climate change is a subject that invokes many different opinions and reactions from different people in different regions. Although there is a general consensus in the scientific and environmental advocate communities as to that the worldwide climate is changing, specifically warming, and that the activities of man are the primary cause, as for the degree of change and the possible effects, there is anything but a consensus. There is a fairly new concept that is taught in many businesses, colleges, and universities called the triple bottom line. This is referring to the three things that businesses should concern themselves with and strive to achieve excellence in if they wish to be sustainable; they are “profit, people, and the planet” (Elkington, 1995). The purpose of this research is to find out and explore some different ways that businesses today are utilizing good sustainability practices, and dive into some other areas like accounting for carbon emissions, and also seeing how accounting for predicted outcomes might work in the business environment. The environment affects us all and any sort of change, contingency, or preparation has to be accounted for, so this work is designed to find out how it is being done, and things that could be done to improve business. The triple bottom line The age old practice of businesses being concerned strictly......

...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......

Climate Change

...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......

Effects of Climate Change and Global Warming in Agricultural Regions

...Agriculture as a percentage of GDP has decreased over past four decades, currently contributing around 2%. This implies that the economy is maturing, moving towards the secondary and tertiary sectors. However, farming remains vitally important to the economy with 638 000 people formally employed (Statistics SA, 2012 Q2) – although it’s estimated that around 8,5-million people are directly or indirectly dependent on agriculture for their employment and income. However, global climate change will affect the government’s efforts to alleviate poverty and fast-track development in rural areas. Definition of terms Global warming: refers to the increased temperature of Earth's surface, including land, water and near-surface air. Climate change: means a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods (UNFCCC). 2. Causes of Climate Change Any factor that causes a sustained change to the amount of incoming energy or the amount of outgoing energy can lead to climate change. They are factors that operate in favour of climate change; these factors that cause climate change can be divided into two categories. Those related to natural processes and those related to human activity. 1|Page 2.1.Natural causes There are a number of natural factors responsible for climate change. Some of the more prominent......

Three Effects of Climate Change

During high school when I was instructed to learn about global warming it was just a mere discussion based on the potential effects humans had on the climate. Approximately eight years later the suspected effects, of careless exertion of the earths resources among other influences, have drastically impacted the world and scientist have agreed that it is the cause of climate change. I was aware of climate change and I’ve witness many natural disasters over the years due to news broadcastings; such as hurricane Katrina, Washington’s mudslide and most recently Arkansas deadly tornado. However, I never truly grasp the importance of the earth’s current situation until I furthered my research in college. According to the ShowTime docu-series “Years of living dangerously” climate change is inevitable due to the amount of earth’s resources used verses those that are replenished. The documentary opened my eyes to the high tempatures that are spreading across the country and one of the biggest causes of climate change, which are green house gases. The tragic causes of these gases develop from the burning of fossil......

The Causes and Consequences of the Enhanced Greenhouse Effect and Global Climate Change

...consequences of the enhanced greenhouse effect and global climate change Figure [ 1 ] - The greenhouse effect diagram, http://www.ozcoasts.gov.au/indicators/images/oze_fs_009_02.jpg Figure [ 1 ] - The greenhouse effect diagram, http://www.ozcoasts.gov.au/indicators/images/oze_fs_009_02.jpg “The unprecedented increases in greenhouse gas concentrations, together with other human influences on climate over the past century and those anticipated for the future, constitute a real basis for concern” (American Geophysical Union, 2014). The Earth's surface temperature has to be just right for humans, not too cold and not too hot. Thanks to the natural greenhouse effect, which has kept the Earth warm. It’s a phenomenon where the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but absorb heat radiated back from the earth's surface. As there are naturally occurring greenhouse gases in the atmosphere that help keep the Earth warm, added amounts of these gases leads to extra heat being trapped in the Earth’s atmosphere. These gases (carbon dioxide, methane etc.) are being added by human activities and are enhancing the greenhouse effect as shown in figure 1. The global climate change is causing many environmental consequences and will cause more. There are five gases that contribute to the enhanced greenhouse effect. These five gases are......

Climate Change

...Over the last century, climate change has become one of the greatest threats facing the world. There is overwhelming scientific consensus that the increasing global temperature and the variable weather condition are closely related to the increase of greenhouse gases. In order to tackle the issue of climate change effectively, the Kyoto Protocol has been established. However, the rate of climate change is beyond prediction and the adverse impacts of climate change are increasingly serious. Besides, the debate about the main cause of climate change is significant. As the main driver of climate change is difficult to identify, countries face the challenge to formulate practical strategies to reduce greenhouse gases. This report will define climate change and explore what is the main driver of climate change as well as focus on climate change response strategies in Kenya. 2. Definition of Climate Change Climate change is characterized as observed increase in global average temperature of the earth. Climate is totally different from weather. Weather is the state of atmosphere at a place and time as regards heat, cloudiness, wind and rain (CCIR-NYC 2005, p. 1). However, climate is a region’s weather patterns in a relatively long period (CCIR-NYC 2005, p. 1). The CCIR-NYC (2005, p. 1) claims that the variations of the state of climate on space and time are the dominant features of climate change. It is reported that global average temperature has increased by 0.74℃......

...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......

Climate Change

...We read and hear so much about protecting the environment, because many different environmental issues are beginning to make a profound impact on Earth. One of those environmental issues is Climate Change. However, one question that we constantly ask is, ‘Why is this so important?’. Climate change is already beginning to transform life on Earth. Around the globe, seasons are shifting, temperatures are climbing and sea levels are rising. And meanwhile, our planet must still supply us – and all living things – with air, water, food and safe places to live. If we don't act now, climate change will rapidly alter the lands and waters we all depend upon for survival, leaving our children and grandchildren with a very different world. Along with the alteration of our land and many other negative transformations, climate change comes with numerous other threatening consequences. Examples of these include endangerment of wildlife, increase of heat related diseases and illnesses, stronger storms and increased storm damage, and economic losses. Each and every one of these effects can cause numerous intense impacts to the way we live today, and as mentioned, for our descendents in the future. Gases emitted by power plants, automobiles, deforestation and other sources are warming up the planet, and contributing to rising temperatures. In fact, according to scientific records and meteorologists, the five hottest years on record have all occurred since 1997 and the 10 hottest since 1990...

Effect of Climate Change on Poultry Production

...EFFECTS OF CLIMATE CHANGE ON POULTRY PRODUCTION 1.0 INTRODUCTION Poultry are birds such as the domestic fowl, Turkey, Duck, Goose, Ostrich e. t. c which are of economic importance to man. Their production is one of the livestock production with significant contribution to human food (Demeke, 2004). It is the primary supplier of eggs and meat as a source of income and employment to people compared to other domestic animals (Avila, 1985). They are raised with relatively low capital investment and readily available household labour. For instance poultry egg contains 74% water, it is a good source of high protein and it is often used by nutritionist as a standard reference for evaluating other protein foods. Studies have shown that the level of performance of poultry does not depends on inherited capacity, but also to a great extent upon the environment (Campbell and Lasley, 1975). The environmental conditions affecting the performance, relative humidity, light, sunshine prevailing at a given time, housing system and ventilation. High temperature and humidity have some negative effects on poultry such as an increase on poultry body temperature: a decrease on feed consumption ( Cowan and Michie, 1978; Howlider and Rose, 1987) and feed efficiency. High temperature also results to a reduction in poultry live weight ( Mowbray and Sykes, 1971), growth speed and high mortality (Arjona et al., 1988) in addition to a decrease on productivity and quality of the eggs (Ozbey and Ozoelk,......

Effect of Climate Change in Indian Economy

...IMPACT OF CLIMATE CHANGE POLICIES ON THE GROWTH OF THE INDIAN ECONOMY Submitted by: Kriti Bhardwaj Date: 1st December, 2010 1 ABSTRACT The most contentious global debate today is the obligations of the developed and the developing countries to take steps to reduce their carbon footprint. Though climate change is a danger for all countries-developed and developing alike, the quantum of responsibility for mitigating climate change is a debatable issue. There is a perceived divide between the obligations of the two worlds in which our planet is divided. The source of virtually all past emissions i.e. the developed world has a greater responsibility to take steps to reduce their carbon emissions substantially and help in stabilizing the environment which they disturbed to a large extent. This is the reason why they are subjected to binding targets of reducing their emissions by a set amount in all international agreements. However, the developing world is gearing towards development at a very fast pace and all development and industrialization pre-supposes the need of higher emissions. Due to this, the emission levels of this part of the world are bound to increase even more rapidly. Mitigating climate change in developing countries poses a fundamental challenge. For developing nations as a whole...
