The National Climate Assessment ( Nca )

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

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

The observed climate changes and warming are prompting sweeping effects in every state in America and throughout its economy. Most of these changes, although some could be advantageous in the short run, are unfavorable, mainly because the design of the American society and its infrastructure was for the climate that the country experienced before, not the present, rapidly-varying climate that its inhabitants have been

Climate change is a heavily ignored subject to many industrialized countries and businesses. While 97 percent or more scientist agree on published peer-reviewed studies that climate change is real, many of the leading industries producing pollution turn a blind eye to the obvious detrimental effects that they are causing. In a multitude of studies on climate change data is showing rising sea levels and global temperature, warming of oceans and shrinking of ice sheets, decreased snow cover, ocean acidification, an increase of extreme events with exceeding power, rapidly declining arctic sea ice, and more. The Intergovernmental Panel on Climate Change, which includes 1,300 independent climate change experts, have actualized 95

Over the last 50 years, human activities – particularly the burning of fossil fuels – have released sufficient quantities of carbon dioxide and other greenhouse gases to trap additional heat in the lower atmosphere and affect the global climate. In the last 100 years, the world has warmed by approximately 0.75°C. Over the last 25 years, the rate of global warming has accelerated, at over 0.18°C per decade.

Climate change, on the other hand, examines the shift in temperature, wind and precipitation over several decades (EPA, 2015). Greenhouse gases have a major impact on climate change because they are responsible for reflecting the heat back that is released from the earth’s surface. The heat is responsible for the shift in temperature, precipitation and wind patterns experienced on a global scale (EPA, 2015). The earth’s surface temperature has increased by 0.74°C in the last century and the current data suggest that the rise in the temperature is due to an increase in carbon dioxide (CO2) released into the atmosphere (Nuleas et al., 2013). An increase in greenhouse gases has results in significant changes in climate patterns.

The main cause for global warming can be accounted to the “human expansion of the greenhouse effect” (“A Blanket around the Earth” par. 1). Humans expand the greenhouse effect through many activities and processes: using landfills, burning fossil fuels, industrialization, deforestation, agriculture, and even the use of livestock. While it seems like these activities would not have much to do with the expansion of the greenhouse effect, they emit gases that can stay in the atmosphere for an extended period. There are gases in the atmosphere that prohibit heat from escaping; the ones that do not react to alterations in temperature “are described as ‘forcing’ climate change” (par. 2). Carbon dioxide, methane, and chlorofluorocarbons are gases whose emissions have increased due to human activities.

Global warming is the gradual increase in the overall temperature of the Earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants (Collins). The current climate changes that are occurring all over the world have sparked a growing controversy on whether global warming is true or false. Many of these individuals who play a role in this controversy argue that the current climate changes are simply part of the cycles seen in the earth’s geological history or that it is simply caused by an increase in the brightness of the sun. This point-of-view is understandable as humanity is dependent on the climate for survival. However, many climatologists and scientists have found that the current climate changes are much more worrisome than previous climate changes. They have found that carbon dioxide (CO2) levels have increased over the years because of an increase in the use of coal, oil, and gas and that the Earth’s current pattern of warming is greater and faster than that of prehistoric warming episodes.

We are facing the consequences of global warming mainly in result of our burning of fossil fuels and releasing heat-trapping gases into our air. Ninety-Seven percent of climate scientists have agreed that the climate trends that have occurred over the past century are likely due to human activities. We have created what is called “the greenhouse effect”; a warming that occurs when the atmosphere traps heat that is radiating from Earth toward space. Sunlight passes through our atmosphere and warms Earth’s surface, this heat is supposed to radiate out into space, but most of the outgoing heat is instead absorbed by certain greenhouse gas molecules that block the heat from escaping, instead emitting into all directions, warming instead the surface of Earth and the lower atmosphere.

Global warming represents a very large threat to our planet. But first off, what is global warming? It is the significant increase in the Earth’s temperature over a short period time as a result of human activity. A congruous mix of organisms, people, and environments are being harmed. Ocean levels have risen, species are becoming extinct, and the natural world is not what it used to be. Regardless of whether this is a large risk is yet indeterminate, whatever the impacts of global warming may be, it is most likely that the outcomes will be enormous, causing illnesses and financial decay. Because of global warming, many are beginning to invest in energy-efficient supplies and do a variety of other acts. For example, carbon dioxide (C02) is an important factor on earth. It is causing a warming impact on the world's surface range. Since water vapor itself is an ozone depleting substance, this causes significant additional warming. Then, the warming causes more water vapor to be vanished. The C02 level is relied upon to develop in the long haul due to keeping consuming of petroleum derivatives. Different gases, for instance, C02, Sulfur, CFCs, and Methane are additionally in charge of a dangerous atmospheric deviation. Industrialization, urbanization, and deforestation likewise are expanding the generation of these gases.

Climate change is at its all-time high. It has taken impact on the planet through the most recent century. The human race as a whole does not take the subject of matter serious. Climate change is caused by many factors, humans seem to be one of the greatest factors. Over the years the human race has caused a great influence on climate change and as the years go by the damages are worse than the years before. The impacts of climate change are continually ending up more obvious across the world. The amounts of carbon dioxide, which is known as one of the main heat-trapping greenhouse gas that is produced by humans, are the highest it has ever been in three million years. (Weeks 522)

Global warming represents an immense threat to our planet. But first off, what is global warming? It is the significant increase in the Earth’s temperature over a short period time as a result of human activity. A congruous mix of organisms, people, and environments are being harmed by its effects. Ocean levels have risen, species are have become extinct, and the world is not what it used to be. This is a large risk for the earth, and the outcomes will be enormous, causing illnesses and financial decay. Because of global warming, many are beginning to invest in energy-efficient supplies and do a variety of other acts. For example, carbon dioxide is causing a warming impact on the world's surface. Since water vapor itself is an ozone damaging substance, this causes significant additional warming. Then, the warming causes more water vapor to be vanished. Different petroleum gases, for instance, C02, Sulfur, CFCs, and Methane also hurt the Earth. Industrialization, urbanization, and deforestation additionally expand and add on to the cause of global warming.

In the past fifty years, the average temperature has accumulated at the fastest rate in recorded history (“Introduction”). Global warming is a rapid increase in the earth’s average surface temperature. Since the Industrial Revolution began in 1750, everyday human movements have contributed substantially to climate change by adding CO2 and other gases that trap heat into the atmosphere (“Causes”). The earth’s temperature has increased drastically over the past few years. One of the causes is the greenhouse effect. The greenhouse effect occurs when gases are released by people burning fossil fuels; this is changing the world’s atmosphere and temperature immensely. Fossil fuels contain overwhelming amounts of carbon dioxide which leads to the heating of the planet. Humans also have been cutting down trees which help turn carbon dioxide into oxygen. This helps contribute to global warming. Over the years, research has shown that climate change is caused by humans’ manipulation.

The idea of global warming has been around for over one hundred years, but in recent decades climate change has become a serious threat to national security. To better understand, global warming is defined as the gradual increase in the overall temperature of the earth's atmosphere, generally recognized as the greenhouse effect, and is caused by increased levels of carbon dioxide, CFCs, and other pollutants, also known as greenhouse gases. Researchers have debated for years about the main causes of global warming. Although history can show that global warming is inevitable, the majority of evidence points to human industry and agriculture as a primary cause for this

During the past century, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere. Most of the gases come from burning fossil fuels to produce energy. Greenhouse gases, such as carbon dioxide, is absorb and emits heat into the earth’s atmosphere, keeping the Earth warm enough to support life. However, human activities, such as burning fossil fuels, are adding large amounts of greenhouse gases to the atmosphere. Greenhouse gases are like a blanket around the Earth, trapping energy in the atmosphere and causing it to warm. This is called the greenhouse effect and it is natural and necessary to support life on earth. However, while greenhouse gases buildup, the climate changes and result in dangerous effects to human health and ecosystems. People have adapted to the stable climate we have enjoyed since the last ice age which ended several thousand years ago. A warmer climate can bring changes that can affect our water supplies, agriculture, power and transportation systems, the natural environment, and even our own health and safety. There are some climate changes that are unavoidable and nothing can be done about it. For example, carbon
