C) the production of CO2 by respiration. D) the burning of vast amounts of rain forests. E) none of the above 2) Which of the below statements about global warming is FALSE? A) Greenhouse gases allow sunlight to reach and heat the earth. B) Greenhouse gases prevent heat from leaving the earth.
Carbon dioxide does not only cause problems in the atmosphere but also in the ocean. The coming of industrial advancement has brought many changes in the earth’s environment (Gibson et al., 2011). Industrialization has brought an increase in gases released into the atmosphere; carbon dioxide forming the largest percentage. The ocean absorbs about 30% of the carbon dioxide in the atmosphere and, thus the increase of carbon dioxide in the atmosphere leads to a corresponding increase in the amounts the ocean absorbs. When the ocean absorbs carbon dioxide it reacts with water to produce chemicals such as bicarbonates and carbonic acid, which lowers the pH of the ocean.
Coal, natural gas, and oil are burned for energy in many ways such as cars and power plants. Forest burning for deforestation also causes C02 emissions. C02 emissions are harmful to the planet and cause the planet to heat up. Global warming causes worse weather conditions in the world amongst other issues. With so many issues that can arise with a hotter Earth, I believe this to be a major issue that needs to be addressed.
How can alternative sources of energy be harnessed effectively? We are running out of our most important natural source of energy, fossil fuels. Fossil fuels are non-renewable natural fuels that were formed by the decomposition of animal and plants that lived up to 100-300 million years ago and humans cannot manufacture Fossil Fuels. The price of fossil fuels is also rising across the globe and when the fossil fuels are burned, it damages the already deteriorated environment. The burning of the fossil fuels is also the main contributor to global warming.
It increases as the Earth’s atmosphere warms which makes it the most feedback mechanisms to the green house effect. Carbon Dioxide is released through natural activities like volcano eruptions and human activities like deforestation and burning of fossil fuels. We have seen that humans have increased their atmospheric CO2 concentration by a third since the Industrial Revolution. Methane is a hydrocarbon gas, which is produced through natural sources and human activities such as decomposition of wastes in landfills and rice cultivation. Methane is a more active green house gas than CO2 but is less abundant in the atmosphere.
Michael Crichton says we can't predict the future. Does this preclude our taking steps to reduce heat trapping gas emissions? Why do we have to act now to reduce our dependence on fossil fuels? 1. How was Crichton able to take the same data that climate scientists use and come to the conclusion that global warming isn't a real threat?
The Globe is losing its Cool Global Warming Melissa Moran University of Phoenix Axia collage Professors name SCI 275 October 21, 2009 There are many reasons for the change in the climate. Climate change also known as global warming is the change in the average temperature of the earth surface, and the change in wind and precipitation. Global warming is caused by releasing fossil fuels into the atmosphere. Many factors such as human activity and greenhouse gas emissions contribute to global warming. Global warming also has natural causes though they are often down-played in the media.
“Their influence is known as the greenhouse gases, which are carbon dioxide, chlorofluorocarbons, methane, nitrous oxide, ozone, and water vapor”(“American Meteorological Society 2007”). These gases mixes with the sun ultraviolet rays, disburse into the earth atmosphere with harmful results. Carbon dioxide from the burning of fossil fuels is one way the human activities effects the environment. Carbon dioxide from the exhaust of cars in heavily polluted cities, farming machinery such as tractors, and smokestacks of refinery companies are just some of the ways carbon dioxide gases are release into the atmosphere by human contributors. The nitrous oxide gases affect the aquatic ecosystem food web chains, which leads from the smallest phytoplankton up to the largest mammal, which is man.
Human activities as had a significant effect on the carbon cycle. The amount of carbon dioxide we are putting into the atmosphere is increasing which is caused by deforestation, burning of fossil fuels and soil degradation (Wright & Boose, 2014, p. 67). By increasing our carbon footprint on our atmosphere we are increasing the greenhouse effect; several scientists believe it is the reason for the increase in atmospheric temperatures (Bennett, 2014). Furthermore, when we burn oil and coal, we are causing the carbon to be released into the atmosphere that has been trapped underground. However, we are lessening our carbon footprint by replanting trees and changing agricultural practices (Wright & Boose, 2014, p. 67).
These gases, with carbon dioxide being the main culprit, prevent solar heat from escaping the earth’s atmosphere, resulting in a rise in temperature, or the greenhouse effect. Already scientists around the world are detecting the numerous and dangerous effects of global warming (Johnson 18). Through these different leaks and spills our Canadian environment is slowly being negatively effected. The impacts of global warming on the Canadian environment are immense. Some of these impacts include ice bridges melting, and will have to be replaced with traditional building materials.
