Global climate change, most commonly referred to as global warming, is a worldwide problem facing our environment. Global climate change is simply a rise or fall in Earth’s temperature over a period of time. Although this problem has natural causes, the true detriments come from humans and how we live day to day. Although many people have heard of climate change, there is not a big effort to fix this problem or to understand it. The best way to rectify this change to the environment is to help others recognize the causes of this problem and the effects they have on our planet. By researching, one can determine their impact on the climate, as well as how to reduce this effect. To understand how to fix global climate change, we must first understand how it started, how it continued, and how it got worse, eventually leading to further problems that will arise in the future. We need to understand global climate change and its causes, so we can come together and prevent further damage to our Earth, and try to make changes to lessen the effects of this environmental transformation.
To comprehend the present and future of global climate change, it is vital to understand its history. It earth's atmosphere, there is a greenhouse effect. This is the way that the planet warms, and traps heat that has been radiated form the earth's surface (encyclopedia of science). The gases that affect this heat-level consist of water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (nasa.gov). In the past, there have been many situations that have altered these levels and, therefore, changed the climate. Volcanoes are a good example of this. When a volcano erupts, it creates dust and particles as well as lava. This pollutes the air,...

Climate change is a global problem because this Earth is home to many, and the artificial sources causing climate changes have been caused by many people over the course of many years. The changes can be seen on a day-to-day level through the rise in average surface temperatures (Figure 3A, Figure 3B). Climate change will change landscapes and increase sea levels due to the melting of ice and changes in water runoff; put wildlife at risk of extinction; increase the risk of drought, wildfires, and floods; lead to increased likelihood of storm damage due to stronger storms and storms occurring in previously not at risk regions; and cause a development in more heat related illness (“Climate Change: Threats and Impacts”). The repercussions of climate change will affect every nation, and major changes will have to be made for everything from farming to fashion. With every way of life at risk and every person and nation making contributions, whether extreme or minute, climate change is undoubtedly a global
In order to better understand global warming it is important to understand the rising of the earth's average temperature, the man-made causes of global warming, and the ways that we can try to prevent it. There are many things people can do to help. These things can include using environmentally friendly products, lowering the production of carbon dioxide, and even recycling. Global warming is an impending and major problem for civilization, and if people do not start taking the threat of global warming serious there could be major implications in the future. Global warming can be stopped if people have the desire to stop it. If global warming is not stopped soon this Earth will be extremely different for future generations, and may lead to our demise.
Global warming is a scientific, political, and controversial topic. Some believe it is catastrophic, a slow moving killer hiding in the shadows. Others do not even think twice about it as they race by in a Hummer. Global warming is the gradual increase of temperature throughout different climates. It is caused by the greenhouse gas effect in which greenhouse gases, like methane and carbon dioxide, reflect sunlight back and forth. This reflected ultraviolet light bounces between the earth and the ozone layer and becomes trapped, resulting in a gradual rise of temperature. Over time, the slow rise of temperature causes new climates throughout the globe. The article “What Megablazes Tell Us About the Fiery Future of Climate Change” by Tim Dickinson
Global warming is an increase of carbon dioxide, nitrous oxide and methane disrupting the earth’s ecosystem ultimately causing climate changes, this is just one of the tradeoffs of the modern life we live. Some doubt that global warming is a real issue despite the increasing natural disasters, freak weather and populations of species becoming extinct. Global warming is one of the challenges that we are facing today, it is much like the climate changes faced in the past but our climate is changing more rapidly. Wi...
When climate change occurs there are a few major effects that are critical to climate change. First the sun passes through the clear atmosphere with its solar rays which then reach the earth's surface. Then, about 70% of the sun’s solar rays are absorbed by the earth surface making the temperature rise while the rest go back into the atmosphere. Some of the rays escape back out into space, while some are absorbed by gases in the atmosphere. These gases are important because they allow the sun to heat the earth and then the gases get trapped, making the earth warmer. They trap the heat like a big blanket to maintain the planet at a stable temperature.
Climate change is a term used to describe the increase in the average temperature of the earth’s surface and has been a major problem recently. Our world is constantly changing and therefore so is our climate, as our country industrializes we create more greenhouse gases from the immense human activity being produced. “These gases get into the atmosphere when coal, natural gas and oil is burned for energy and over the last century the burning of fossil fuels like coal and oil has increased the concentration of carbon dioxide… the clearing of land for agriculture, industry, and other human activities has increased concentrations of greenhouse gases.”(NASA 1). Climate change is causing global warming that causes the earth to heat up rather than
Scientists and environmentalists started talking about global warming and the dangers of climate change long time ago but it is now when the consequences of these effects began to manifest themselves in a clearer and even worrisome manner. The temperatures on Earth are rising, the sea level is rising, the amounts of CO2 and ozone in the atmosphere are increasing, the amount and timing of precipitation is changing. All of these issues show tendency to worsen in the future, though it is hard to predict exactly by how much or at what rate they will unfold. One thing is clear – climate change has an impact on almost every area of our life and it deserves our attention and timely response.
Climate change, is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time. These times can be anywhere from decades to millions of years. The Earth’s climate has constantly been changing throughout history. Climate change can be dated back to over 650,000 years ago. Most of the changes that happened before 7,000 years ago happened because of small variations in Earth’s orbit that change the amount of solar energy the earth planet receives. Even though climate change is natural, people are speeding up the process at which it occurs by polluting. Climate change has many impacts all over the world and its effects are evident. People can still slow down the process at which climate change
The article “an introduction to climate change” describes in detail about the causes of climate change, and its potential effect on earth. According to this article, the global warming is due to the accumulation of carbon dioxide and other pollutants formed from burning fossil fuels that accumulate on earth’s atmosphere so that light rays are reflected back to the earth surface causing the atmospheric air to heat up. In addition, the article also gives some relevant solutions to global warming such as reducing air pollution and use of “clean energy.”
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future.
This is based upon the sunlight and volcano eruptions which plays an extreme factor. "Most often, global climate has changed because of variations from sunlight. Tiny wobbles in Earth’s orbit altered when and where sunlight falls on Earth’s surface. Variations in the Sun itself have alternately increased and decreased the amount of solar energy reaching Earth. Volcanic eruptions have generated particles that reflect sunlight, brightening the planet and cooling the climate. Volcanic activity has also, in the deep past, increased greenhouse gases over millions of years, contributing to episodes of global warming." (Global Warming, web.) However, I firmly believe that climate change is not only the result of natural causes alone. I think it is man-made and the major factors are from CO2, factories, and power plants burning coal/ oil, natural gas.
Many climate scientists, researchers, and environmentalists are expressing concerns about shifts in the overall climate of the earth. It is believed that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. This temperature rise is due to the damaging effects of deforestation and the burning of fossil fuels. It is our responsibility to preserve our planet and our way of living but in order to do that we need to act now. If we continue to destroy the planet with no regard as to how serious this matter is there could be several negative effects to us as human being and other living thing on Earth. This is why global warming is truly a global issue and needs to be tackled collectively. We must to act now in order to reduce the dangerous levels of carbon dioxide emissions and we must to work together.
One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”). Everyone should be knowledgeable about global warming and the dangers that it brings to our planet. This essay will examine
Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. The greenhouse gases are carbon dioxide, methane, and nitrous oxide. “Carbon dioxide is released into the atmosphere when solid waste, fossil fuels, and wood are burned.” (2) The gases help to warm the surface of the Earth. Each greenhouse gas absorbs heat differently. If natural gases did not occur, the temperature of the earth would be considerably cooler. “Problems can occur when higher concentrations of greenhouse gases are present in our atmosphere because they have enhanced our earth's heat trapping capability.” (3)
