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
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.
Many of the ocean’s and Great Lake’s properties can be altered due to climate change. The two important indicators of climate change in the Atlantic Ocean and Great Lakes are sea level and sea surface temperature. In the Atlantic Ocean, as greenhouse gasses trap more energy from the sun, the ocean is absorbing more heat. This results in an increase in sea level and sea surface temperature. The overall increase in sea surface temperatures has occurred during the past three decades.
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.
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.
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 impact of human activity and the emission of carbon dioxide in the earth’s atmosphere is linked to global warming. Sea surface temperatures have steadily had increases up to about 1.5 degrees Celsius over the past 54 years. Climate change continues
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.
Now another natural cause of global warming is the rising of the seas. The biggest reason for sea level rising is that global warming is causing the air to be warmer and that 's causing glaciers and ice-caps to melt. Sea level rise would affect about 11 out of the 15 biggest cities in the world. The reason this is happening because gases are being released into the atmosphere which is causing the temperatures to rise, which causes the seas to rise. Sea level rising means more money that we have to spend for people living on the coastlines because coastal populations are growing and people are crowding into coastal areas and that area could be underwater in a few years if sea levels keep rising how they have been.
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 increase in volume of carbon dioxide and other greenhouse gases released from the burning of fossil fuels, land clearing, agriculture, and other human activities. As we all know, global warming can lead to many serious consequences and there are some ways that we should take before the situation turns worse. One of the main effects of global warming is on human health. This is because as the temperature of the atmosphere increases rapidly and the earth becomes warm, it affects the health of human and they are exposed to diseases. With the increase in the rainfall, disease such as malaria that transmitted by water are likely to spread.
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.
Humans are the most influential and destructive living things on this planet, and our mistakes are starting to have an effect on our lives. These actions have created the occurrence we know as global warming. This is the average warming of the Earth’s atmosphere and oceans by way of natural warming processes, but is greatly amplified by human emissions of greenhouse gases and pollution. Carbon Dioxide is the major gas that we pump into the air every day, as waste from industrial processes, transportation emissions, and energy production. These gases in the Earth's atmosphere lead to heat that is reflected off the Earth from the sun’s rays to become trapped, creating higher temperatures in the atmosphere, which is in turn, absorbed by the oceans.
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.
