It acts as a blanket to keep our Earth warm and protected from the temperature in space. This is known as the greenhouse effect. The main cause of global warming is the large contribution of Carbon Dioxide (CO2) to the atmospheric layer. What causes the rise in carbon dioxide some may ask, is the burning of fossil fuel used to produce power and electricity, like oil, coal and natural gases. Every time these fossil fuels are burnt, more carbon dioxide is released into the atmosphere, resulting in the thickening of the greenhouse layer, making the Earth a lot warmer.
Climate change is refers to the rise in average surface temperatures on earth, mostly due to the burning of the fossil fuels such as oil and coal, which emits greenhouse gases into the atmosphere which are primarily carbon dioxide, water vapor, methane, nitrous oxide, and chlorofluorocarbons (#02). In addition, other human activities, such as agriculture and deforestation, also contribute to the growth of greenhouse gases that cause climate change (#01). According to this, many have make their own conclusions on how are humans responsible for climate change and whether or not it is a real thing. Some people think and guarantee that climate change is real and it is happening at least in part because of human activity. This people argue that in the last 100 years, carbon dioxide concentrations in the atmosphere have risen from 290 parts per million (ppm) to 369 ppm, with strong evidence pointing to the burning of fossil fuels by humans as a primary cause of these increases (#03).
The steady flow of greenhouse gases that traps the rays of the sun. The suns rays heat up the earth atmosphere, and this causes the melting of glaciers at the poles. To support this theory, according to author Melissa Denchak the “According to the National Climate Assessment, human influences are the number one cause of global warming, especially the carbon pollution we cause by burning fossil fuels and the pollution-capturing we prevent by destroying forests. The carbon dioxide, methane, soot, and other pollutants we release into the atmosphere act like a blanket, trapping the sun 's heat and causing the planet to warm.” This shows that due to human advancement in technology we have in a sense changed the environment for the worst. The global
Earthobservatory.nasa.gov. N.p., 2017. Web. 8 May 2017.) Overall global warming will impact life on earth in many ways but the extent of the change is largely dependent on human activities as scientist have shown that human emissions of greenhouse gases are pushing global temperatures up.
Ever since the industrial revolution, the amount of carbon dioxide in the atmosphere has increased drastically. The large amount of carbon dioxide was produced by human activities such as burning gases, woods, and burning coal. Clearing forests also releases large amounts of carbon dioxide. Worldwide deforestation means that we don’t
While orbital forcing is the primary external driver of glacial cycles, carbon dioxide content in the atmosphere plays this important internal feedback role (Pittock, 2005). Evidence for environmental change in the Pleistocene epoch include constituents of gas bubbles trapped in ice cores. According to BAS Natural Environment Research Council (2015), Ice cores are cylinders of ice drilled out of an ice sheet or glacier, with most of them coming from Antarctica and Greenland. Looking at ice cores can provide direct information about past climate change, going back as far as at least 800,000 years. They also provide evidence that under some circumstances climate can change abruptly.
Climate change is a very serious and growing problem in our world today. It can be defined as a change in global or regional climate patterns, and is accounted for the increased levels of atmospheric CO2 produced by fossil fuels. There are various factors that partake in climate change both natural and human, but scientists believe the largest component is the greenhouse effect, (process by which radiation from a planet 's atmosphere warms the planet 's surface to a temperature above what it would be without its atmosphere). Some long-term effects of climate change can include an increase in heat waves and heavy precipitation, a decrease in sea ice, an increase in permafrost thawing, and decreased water resources in semi-arid regions (USGS Science for a changing world, Campbell).
Natural climate change can be divided into two sections, long-term and short term. One of the long term changes is continental drift. Our continents shifted over time and moved over the surface of the Earth over millions of years to what our continents look like today, as seen in Figure 1. (“Causes of Climate Change”, Edgar). Figure 1: Continental Drift At the Permian and Triassic eras, we had ‘supercontinents’.
The first question “What is Global Warming?” Global warming is the gradual increase of the temperature of earth 's atmosphere and oceans. In simple word, it means the global is hotter and hotter day by day. So What Causes It? Global warming occurs when greenhouse gases, such as carbon dioxide, nitrous oxide, and methane trap heat inside the earth 's atmosphere. Think about what happens when you open your car door after the windows have been rolled up on a hot day.
