Transformative Essay: The Reality Of Climate Change

1950 Words8 Pages

The Reality of Climate Change Are people really aware that the climate is changing? Are they aware of the effects that Earths varying temperatures will have on them? The topic of climate change is very controversial and has many viewpoints associated with it. The three viewpoints that will be discussed throughout this paper will be; climate change is real and is caused by human intervention, climate change is not real, and the final view to be discussed in this paper is that the climate changing is just a part of Earth’s natural heating and cooling cycles. Also discussed in this essay will be how climate change will affect the human population in the years to come. The United States Environmental Protective Agency defines climate change …show more content…

Paleo data covers the past one-million years. The paleo records state that the Earth goes through these cycles about every 100,000 years and that the Earth is currently in a warming cycle. OSS states that the Earth generally spends around 80,000 to 90,000 years in the cooling cycle and around 10,000 to 20,000 years in the heating cycle. The reason the Earth goes in and out of these heating and cooling cycles is because of a concept called Milankovitch cycles.
The “Milankovitch cycle’s” concept was developed by Milutin Milakovitch; a Serbian mathematician. According to “Milankovitch Cycles”, the Milankovitch cycles “describe the changes in the way the Earth orbits the sun”. This rotation then changes the Earth’s temperatures in the sense of heating and cooling cycles. The concept states that it looks at three variations of the Earth orbiting around the sun. They say:
The earth’s orbit changes from being nearly circular to slightly elliptical (eccentricity). This cycle is affected by other planets in the solar system and has a period of around 100,000 years. The angle of tilt of the earth’s axis changes from 22.1° to 24.5° (obliquity). This cycle has a period of 41,000 years. The direction of the tilt of the axis changes (precession) on a cycle of 26,000

Almost anyone who will read this essay has undoubtedly heard of the climate phenomenon Global warming. Global warming is a topic that gets discussed very often nowadays, most notably during political debate and discussion. Politicians use certain stances on global warming to appeal to voter’s emotions and logic in order to gain votes and support for their campaign, however climate change is nothing new, during the past several hundred thousand years the Earth has heated up and cooled down and even experienced so called “ice ages”, which is a period where glacial deposits located at the northern and southern hemispheres have grown due to dramatic global cool downs. Don’t be confused by climate terminology though, the global warming so widely

Changes occurring in the sun itself can affect the climate change on Earth. The intensity of the sunlight reaching the Earth can cause either warming or cooling. The sun flows a natural 11 year cycle of small ups and downs in intensity, but the effect of it on the Earth’s climate is negligible. However, over the past years, the sun’s intensity has been lower than the mid 20th century, and therefore does not explain the recent warming of the Earth. • Also

We see the evidence every day, for example the unpredictable weather patterns like milder winters, severe snow storms, the polar vortex, torrential rains, severe droughts, hotter than normal summers, an increase in tropical storms, and the rising sea levels. Also, the glaciers and polar ice caps are melting at an increased rate. Policymakers were given summary reports that were completed by the Intergovernmental Panel on Climate Change Working Group I (Solomon, et al., 2007). These reports have supporting evidence that climate change is very real and affecting all

In the mid-19th century James Cross, a Scottish scientist, suggested that variations in the earth’s direction near the sun was responsible for cooler time periods; however, this view wasn’t widely accepted. In 1857, an independent scholar and self-taught astronomer, James Croll, argued that until we find the cause of the “Ice Age” we will not know the rest of the story. Making the assumption that the earth is warmed by the sun, Croll decided to calculate the variations of the earth’s orbit as well as its tilt. Due to the earth’s tilt the Northern and Southern Hemispheres receive varying amounts of direct sunlight and would contribute to hot-cold cycles.

People may know about climate change and the drastic changes it is having on the environment, but what they may not be aware of is that another degree increase in the world’s average temperature will cause even bigger problems for people all over. Climate change is long term shifts in temperature and patterns in the weather. Greenhouse gasses, gasses that trap heat in the atmosphere causing it to warm up are at an all-time high due to humans and the amount of fossil fuels we use. The most crucial result of climate change is global health, but animal endangerment and the rise in sea levels are also very important effects.

The earth was covered with extensive polar and mountainous sheets of ice. So much water was taken up with ice that the global sea level dropped almost 140 meters. This time in earth’s history would be considered a glacial period. Oceanic circulation, solar energy fluctuations, continental positions and earth 's orbital cycle caused these conditions. Glacial global temperature changes between the ice ages and interglacial periods were due to the concentration of greenhouse gases.

In the Hadean eon, Earth was very hot. This is because the heat that was received from the Sun was very low, while the radiation of heat from Earth’s interior was much larger. During the Archean eon there was high concentrations of carbon dioxide and methane, two strong greenhouse gases that add heat energy to the lower atmosphere. Years later though, temperatures started to drop.

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.

Continental drift makes the Earth’s climate change in many ways, ocean currents being one of them. When a continent is close to a large body of water, the water averages the temperature and administers more moisture. The ocean currents are responsible for moving water around the Earth. If land masses move closer to the North Pole, the

Climate Change This quote said by Washington State Governor, Jay Inslee shows the severity of climate change “We are the first generation to feel the sting of climate change, and we are the last generation that can do something about it.” “On Earth human activities are changing the natural greenhouse of the Earth.” (A blanket around the Earth). Burning fossil fuels is causing carbon dioxide to be released into the air.

Throughout history Earth`s climate has changed a lot, and there is a lot of evidence that shows how humans have contributed to this changed and effected the Earth. Just in the last 650,000 years there have been seven cycles of glacial advances, the increase in the thickness and area of a glacier. As well as glacial retreats, a condition occurring when backward melting at the front of a glacier takes place at a rate exceeding forward motion. Most climate changes are attributed to very small variations in the earth`s orbit, that change the amount of solar energy our planet receives. The 21st century has seen the most temperature records broken in recorded history.

One of the greatest issues that we face towards the environment has been an increasingly difficult problem over the last few years. Earths climate is changing at rapid paces and solutions are needed as quickly as possible to replenish natural ecosystems and cultures that depend on the environment. Climate change not only affects the animals in our ecosystem, but us humans as well. With the human population increasing every year, climate change is only getting worse. Many argue that the effects of climate change towards the environment are due to other extraneous factors, however, I myself am a strong believer that the problems such as rising sea levels, warmer temperatures and natural disasters are all due to both natural causes and human activity.

Perhaps less obvious but no less ominous a threat to the environment are the general increase in temperatures worldwide and the resulting climate changes. This phenomenon, known as global warming, could have serious negative effects on humans and all other living things on Earth. Global warming is a complex problem, and governments have had great difficulty deciding how to address it. Some people think that it is the work of the world where nothing we do can ether change it or anything we do will prevent it. While others say that the

One factor is the sun’s energy levels which has an 11 year cycle of small changes in the intensity. Earth’s tilted axis and rotations also changes the climate because at times, the sun is closer or farther away from certain areas of earth’s surface. Climate change has major effects to our world that a lot of people don’t realize. Global warming is a major threat for the habitat in the Arctic. The Arctic is warming twice as fast as the rest of the world because the shiny snow and ice is reflecting more of the sun’s energy but as the ice and snow disappears, the water and rock are absorbing the heat and this is known as the albedo effect.

Climate change is the most rising issue of the modern world that is threatening our planet from the last few decades. In the simplest definition, the term climate change refers to the rising of the planet’s temperature, particularly an increase in the average atmospheric temperature. It should be noted that in the last few decades, many scientists and ecologists has discovered the Earth temperature is increasing at an alarming rate and has affected the planet in numerous of way. The constant change in the climate due to various causes is threatening the preservation of the Earth and its human life. It should be noted that the climate change is linked with several of the human activities that are further directed towards the global warming.
