Economic perspective of Climate change Climate is an average weather condition during a region in a given period, it will not change by one day or one night, but instead caused through over time. From the perspective of meteorology, The climate change refers to a specific location, time of regional or global climate change or conversion, based on the all of the conditions associated with the average weather characteristics, such as temperature, wind and precipitation etc. According to the IPCC’s Synthesis Report, “Anthropogenic greenhouse gas emissions have increased since the pre-industrial era, driven largely by economic and population growth, and are now higher than ever. This has led to atmospheric concentrations of carbon dioxide, methane and nitrous oxide that are unprecedented in at least the last 800,000 years. Their effects, together with those of other anthropogenic drivers, have been detected throughout the climate system and are extremely likely to have been the dominant cause of the observed warming since the mid-20th century” (Page4) Human are the main reason to cause the climate change. While during the climate changing in naturally, human activities have altered the chemical composition of the atmosphere, causing the today’s climate change. And this change is not only hindering the progress and development of society but also affect human society and the survival of
According to the IPCC (2007), climate change refers to a change in the state of the climate that can be identified (e.g. using statistical tests) by changes in the mean and the variability of its properties, and that persists for an extended period, typically decades or longer. It refers to any change in climate over time, whether due to natural variability or as a result of human activity. Studies suggest that the global climate has been warming and will probably continue to do so. Thus complicated process drives an array of effects, from distinct events like extreme weather to long-term impacts that vary by location, intensity,
The world economy is a very complex system; in the system harmful externalities disrupt capital flows and determine economic productivity. Most notable of these externalities is inadvertent global warming. Spending towards research and regulation of climate change at both the national and international level are very important in determining current and future business trends. Economists and scientists worldwide continuously debate the pros and cons of emissions reduction and what consequences can quickly follow. Though many have different views on the issue, all can agree that the immediate and long term effects of climate change have become an economic matter of paramount importance. The sweeping impact from climate change will have important fiscal, financial, and macroeconomic ramifications that influence global commerce standards.
Climate change is classified by many different events and reactions that are happening. The first is that the earth’s atmosphere is trapping more heat. “The warming of Earth's climate, due mostly to increased trapping of heat by gases in the atmosphere, often is termed the greenhouse effect. Some degree of greenhouse effect is natural and normal” (Lerner 3). Some percent of greenhouse gases are produced naturally but a majority of the gases are being produced by humans. ”Most scientists agree that this warming trend is the result of loading the atmosphere with carbon dioxide and other heat-trapping gases” (Freedman 2). The atmosphere is being loaded with carbon dioxide and other harmful gases and this is making the atmosphere trap more heat. Changes in air temperature is another factor of climate change. “The greenhouse effect has been extremely important to the evolution and survival of life on Earth. A surface temperature of 59°F is sufficient to maintain the Earth’s reservoirs of life-sustaining liquid water, and to impel climatic
Climate Change- Climate is a long term change in the Earth's weather, especially due to an increase in the average atmospheric temperature. According to research, it was discovered that the Earth's temperature rose by 0.6 degrees Celsius (C) and predicted that the sea surface temperature may rise by up to 1 degrees C over the next 50 years. Unfortunately, carbon dioxide and methane gas levels are the highest they have ever been for the last 420000 years. These two gases with water vapour, nitrous oxide and halocarbons create the five predominate greenhouse gases, effecting the environment greatly. Furthermore, it is evident that an average person release 4 metric tonnes of carbon dioxide per year. Due to this fact, carbon dioxide
Throughout the middle of the twentieth century, until now, there has been debate over the existence of climate change. Climate change is the increase of earth’s inclusive temperature of the atmosphere, and the side effects caused by rising temperatures. Climate change is caused by many reasons: burning of fossil fuels, agriculture, landfills, and deforestation. Climate change is mainly caused by greenhouse gases and humans. The effects of climate change are detrimental to earth; the effects have lead to stronger and more intense hurricanes, a rise in temperature, and the melting of glaciers(“Global Climate Change: Effects”).
The human race all around the world wonders if the climate is changing due to human activity or if it is just a natural occurrence. At certain parts of the Earth's surface, the climate can be observed much differently than other locations. As the years go by the average temperature of the Earth increases by little intervals. There are several different reasons why people believe the climate is changing every year. However, the increase of worldwide population and production of heat to the atmosphere is due to the increase of human activities that take place on a daily basis. Human activity is the main cause of the global climate change. The human impact on climate exceeds any known changes due to natural processes. The impact of this human activity is often misunderstood when looking at climate change.
Climate change is a real problem facing our world with all of the progression of today’s society. The amount of Greenhouse Gas emissions has gone up drastically in the past one hundred years alone. The use of transportation, industry, electricity and the deprivation of the world's natural resources has increased the amount of Carbon Dioxide in the Earth’s atmosphere. The Environmental Protection Agency has shown an increase in the Earth's temperature by 0.8 degrees C in the past century alone. It is proven that humans are the cause of global warming but it is not too late to change how we are.
Climate change is influenced by the greenhouse effect which is the increase of Carbon dioxide, Methane, Ozone and Nitrogen Oxide. On one hand, the presence of these gases in the atmosphere make the earth habitable with respect to regulating the earth’s temperature. However, an increase in the concentration of these gases results in trapping energy in the atmosphere and this in turn increases earth’s temperature. “Global greenhouse gas emissions have grown since pre-industrial times, with an increase of 70% between
Climate change refers variations in climatic characteristics over a period of time ranging from decades to millions of years. Climate change has had an effect on the average weather conditions and distribution of weather events. Climate change is caused by the increased amount of carbon emissions being emitted into the earth’s atmosphere since the Industrial Revolution. The atmosphere traps the emissions and heats up the surface of the Earth therefore altering the Earth’s climate patterns. In the last two centuries the temperature of the Earth’s surface has increased by an average of 0.6 ︒C. Paleoclimatology allows scientists to predict the possible climate scenarios for the future through proxy data. Scientists are able to analysis the severe
This is the topic of our time. Climate change is driving every decision that we make and I believe that this is what politicians are so irked about. The old money that was made on fossil fuels will be obsolete by the new money of green technologies. One of the main problems in the European Union which is great with renewable energy sources is still getting citizens to switch off of older fossil fuel driven technologies due to a cheaper cost and routine (Vašáková 62). The start up cost is always the hard part of going green and I believe politicians are reluctant because it cost votes. What do you both
Global climate has been drastically changing over the past decade reflecting a wide range of impacts that affect not only the environment, but humans as well. Over the last 50 years the magnitude of global warming has been increasing mainly due to human activities. Since the industrial revolution in the 1800s economic growth has been driven by the progress of manufacturing processes, these have significantly contributed to global warming. It is in this period of time when the global concentration of greenhouse gas levels in the atmosphere had a significant increment from 280 parts per million (ppm) in the 1800s to the modern levels of 400 ppm in 2016. (CITE acs.org).Greenhouse gases are the most significant drivers of climate change due to their persistent effects over a long period of time that can therefore negatively affect the present and future generations.
Climate change is a global problem that is affecting Earth’s delicate ecosystem. Many problems are present in our world today, such as starvation, flooding, heat waves, droughts and disease. These issues are likely to worsen as climate change takes its toll. In the past, the cause of this severe climate change was unknown. Today, it is known that manmade climate change is occurring. Scientists have discovered that humans have had the greatest impact on the Earth’s ecosystem. Human activities, such as burning fossil fuels and deforestation, are causing the Earth to get hotter. Although humans are not the only cause of climate change, we contribute to this world wide problem because of the actions we take, which if affecting us now and will continue to affect us in the future.
Climate change is the term used to describe the warming of the average surface temperature on earth. Climate change; often referred to as the general term global warming, is a topic that often inspires fierce debate among those on both sides of the issue. One thing those who are pro and those that are con both agree on is that the temperature on earth has increased over the past century by an average of 1.4 degrees. The big debate on the two sides is if the warming temperatures are caused by human activities and if it is not stopped it will have dire consequences (the pro side) or if it is the result of natural causes and the earth’s surface will find ways to adapt such as crops becoming more heat resistant (the con side).
Climate is sometimes confused with weather, which can lead some people to think that an abnormally cold day can mean that climate change and global warming is a myth. Climate is the weather conditions of an area over an extended period. Climate change is the current warming trend of weather mainly caused by human activities. According to a report written by NASA on global climate change, the main cause of this new human induced, climate change is what’s known as the “greenhouse effect.” The greenhouse effect results when the atmosphere traps gasses, such as carbon dioxide, nitrogen, and methane which causes earth to trap heat (“Global Climate Change”). According to a report by the Washington State Department of Ecology, carbon dioxide and other heat-trapping gasses caused by humans have warmed the earth and are causing many negative
Our Earth was formed 45 hundred million years ago as a mixture of rocks, and there was creatures under the sea starting to grow 2.5-6 hundred million years ago, since when there have been more and more species being found. Thanks to the plants and solar energy, human beings are able to live on this planet. Meanwhile, the weather on Earth changes all the time, and affects our lives. People rely on animals, plants and water, which are all affected by the climate. Besides, for more purposes, people drive vehicles, take planes, which consume fuel, and harmful gases such as carbon dioxide which is released during the burning of fuel. In a nutshell, climate science is related to daily life of people, and our future. Therefore, climate change has been attracting scientists and citizens attention. It has become a serious and wide topic. There is too much hazard of global warming in many ways, such as destruction to environment, food problems, population and refugees. So climate science aims to researching the climate, get used in human’s life, and changing our behaviors to benefit our nation, other nations, and the nature.
