Volcano eruptions, solar output (amount of energy the sun puts out), and the earth’s rotation around the sun all are natural causes in why the climate changes. Climate change caused by human interaction is mainly due to the burning of fossil fuels like coal, natural gas, oil, and other fossil fuels for energy. We are releasing a dangerous amount of carbon dioxide (CO2) in the atmosphere, which make the greenhouse effect stronger. There are two other types of gases that are also released by human activity, which is making the greenhouse effect stronger. These gases are methane (CH4) and nitrous oxide (N2O).
Lower albedo (darker surface) absorbs solar radiation. The absorption of solar radiation leads to an increase in temperature. The trend on the graph shows a decrease of ice in the Arctic. The melting of Arctic ice is an example of a positive feedback. As the ice continues to melt, the color of the sea surface changes.
A combination of climate change, pollution and search for natural resources is threatening the fragile species and ecosystems within the Arctic region. Over the last two centuries the world's global mean temperature has increased by 0.6 degrees, noting this continuous change in global temperatures is too accelerated for the natural environment to adapt to. Much of this change in global temperatures is the result of c02 emissions being released into the atmosphere. Currently, 80% of the world's growing energy demands are met by the burning of fossil fuels which emit astonishing amounts of c02 into our atmosphere (3). As the name suggests, climate change references the change of the climate, unfortunately this is not limited to the fragile systems of
From the start of the Industrial Revolution in the 18th century, humans have been increasing the amount of carbon dioxide they release into the atmosphere (Changes). This causes many different problems such as weather changes, major floods, global warming, and melting ice caps, in which scientist have been given the task of solving. In addition to these effects, CO2 emissions also cause very harmful, but less known problems in our oceans. High levels of carbon dioxide in the atmosphere cause oceans to absorb between 25 and 30 percent of mankind’s emissions (Barry). This rise in carbon dioxide results in the ocean becoming more acidic, creating a phenomenon called ocean acidification.
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 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.
Actually, one of the results of increased CO2 levels are the development of more weeds, pests, and diseases. As mentioned in an article called, “Effects of Climate Change on Agriculture” by North Carolina State University, “Weeds have become more prolific and are expected to invade new habitats as global warming increases.” The article also mentions that pests that may carry plant diseases will become more widespread resulting in herbicides becoming less effective (North Carolina State University). With these problems arising from increased CO2 levels, agriculture will be deeply affected.
As time went on, trees used to help reduce the level of carbon dioxide along with other greenhouses gases got cut down. The numbers of trees and forest began to decrease in order to build homes, factories, and cities. As human life became to advance, we added more pollution into our atmosphere. This began to affected climate change due to the extra amount of heat energy being trap on earth’s surface. The surface of our planet became hotter, it created a breeding ground for droughts, wildfires and massive hurricanes.
Some of it is trapped by a number of gases which resulting in the Greenhouse Effect. Global warming is the increase in average temperature of Earth due to the effect of Greenhouse gases. Greenhouse gases include carbon dioxide, methane, nitrous oxide, hydrocarbons. In 1896 Arrhenius was the first to claim that fossil fuel combustion may at some later time result in enhanced Global Warming.The observed rise in temperature over the 20th century was 0.3 to
Amounts and patterns of precipitation are changing as well but only slightly in comparison to what has been predicted for the future. Changes in temperature and precipitation patterns increase the frequency and intensity of other extreme weather events such as floods, droughts, heat waves, and
