Essay About Climate Change

Climate change is believed to be the biggest issue facing the Earth. It is a long-term change in the Earth’s temperatures and climate (“Climate Change”, Dictionary.com). Our atmosphere is part of the reason why we can live on Earth with reasonable temperatures. Humans have been emitting unnatural greenhouse gases, like coal, oil, and gas. This is changing the natural systems that take place in our atmosphere. When all these extra gases are released, carbon dioxide stars to accumulate in the atmosphere. Climate change is a global issue because when the temperature of the Earth changes even very slightly, it can cause droughts and our crops can die. This is affecting our food supply. Also, when water levels rise even slightly, it can be very destructive for …show more content…

There has been a significant increase in bushfires and droughts, and these have been associated with climate change. Rising sea levels are also very dangerous for Australia. In this report, I will be further mentioning the causes and impacts of climate change, and solutions for climate change.

Causes of Climate Change - 573

There are natural, as well as unnatural causes of climate change. 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’. 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

, changes in shape of the Earth’s orbit and its tilt can also affect climate as that determines the amount of sunlight that reaches the Earth. Similar to what is mentioned in the previous point; the tilt and position of the Earth’s axis affect temperature on very long timescales. This means that it take long for the position and the tilt of the Earth’s axis to change. Therefore, this also fails to explain the recent rapid warming of the

Convection currents, seafloor spreading and rift valleys also drive the movement of the Earth’s plates. When Gondwana drifted apart, Antarctica, South America, Africa and Australia moved into the southern hemisphere and the Arabian Peninsula and the Indian Subcontinent moved into the northern hemisphere. The tectonic plates are always moving and the Australian plate is moving northwards at about 3cm per

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.

Climate change refers to a is the change of a region’s or city's’ typical weather. Both human and natural causes can affect the Earth’s energy balance. Factors include, dissimilarity in the sun’s energy reaching Earth and the buildup of greenhouse gases in Earth’s atmosphere. The United Nations Intergovernmental Panel on Climate used scientist from 27 different countries to report a world policy on Climate change.

Climate change is an irreversible consequence of the damage we do to our Earth. If we do not change our ways, the global temperature will swell, causing an unchangeable series of events, consecrating detriments onto all the existence upon Earth. In only about 140 years, the average global temperature has increased 0.8 degrees celsius, and the ramification is the irreparable destruction of the place where we and millions of other species live. The most important consequence of climate change is the global increase in temperature and how that is affecting various animal species all over the Earth, the health of humans, and the rapid rise of sea level.

By releasing this gas into the air the natural greenhouse gases increase and cause many effects to happen. Carbon dioxide is also caused by removing natural resources from the land for agriculture. When the Earth starts to warm many other things do to, the ocean will become more acidic and glaciers might partially melt. If the oceans become acidic, fish and other sea creatures will have an unlivable environment. If glaciers start to melt arctic animals that rely on the ice may start to become extinct.

All of the greenhouse gases contribute to the atmosphere trapping heat and warming the earth and warming the Earth has many effects. The earth being warmed, meaning from North Pole to South Pole, melts ice in the poles. The melting of the ice causes sea levels to rise and the effect of that is flooding and lost habitat for animals. Increase in temperature makes some of population of plant and animal species go down. Increase in temperature also affects the weather.

Climate Change is one of the most unsettling problems mankind faces today. It leaves an impact on every single living thing, on every continent, no matter the privilege. Long term investment must be used to change the world. People must do more than just change out their light bulbs for eco-friendly ones, or drive fuel efficient cars. A choice as simple as changing our diets could reduce a human’s carbon footprint by fifty percent.

There are two main causes of climate change: natural causes and human causes. Natural causes that influence climate change include volcanic eruptions, ocean current, earth orbital changes, and solar variations. Those natural causes contribute small part of climate change; however, the biggest part in climate change is caused by human. The spectacular increase of human population, contribute significantly to the climate change. There are more than 7 billion people live in the world now, compared to about 3 billion people in late 1960s.

These gases retain heat on earth thus increasing the temperature above average. Different gases have dissimilar abilities to trap heat. Deforestation is also another important reason for global warming. Plants release oxygen and take in carbon, thus providing us a clean and healthy environment. But by deforesting the lands, the trees would emit the carbon stored in them from hundreds of years making the air impure.

Climate Change is something that we have caused because of our choices to burn fossil fuels, at some point we have to face the problems that we have created. The consequences of Climate Change are horrific and Climate Change could end our existence as a species, most people do take action against Climate Change except, The Government of the United States of America, refuses to accept the serious dangers of climate change and continues releasing propaganda on Climate Change, claiming its effects are minimal and that we are not causing it. Peculiar how almost every other government in the world thinks otherwise. The reasons we are heading in the wrong direction is because the actions of humans are causing Climate Change, and almost all scientists agree on this matter. Another reason is the that the government isn’t trustworthy in what they say about Climate Change, meaning what they say about Climate Change is wrong, and we should change our policy on Climate Change.

THE EFFECTS OF GLOBAL WARMING AND THE WAYS TO OVERCOME Nowadays, global warming has grabbed the experts and the scientists’ attention. It is the most critical issue that our world facing in the 21st century. Global warming is the gradual heating of Earth 's surface, oceans and atmosphere. Global warming occurred, when carbon dioxide increases in the air and the air start to be warmer and hotter.

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.
