Global Warming

Lets face it, humans are terrible. We are arguably the worst thing that has ever happened to this planet. It would probably be better off without us. We have had a devastating effect on our planet’s ecosystem. Climate change is happening, and many say that we are responsible for it. Google defines climate change as “a change in global or regional climate patterns”, in particular change brought on by increasingly high levels of carbon dioxide in our atmosphere. High levels of carbon dioxide, and other greenhouse gases, stop the suns rays from being able to leave our atmosphere and thus, warm our planet. This is why this epidemic has ...view middle of the document...

Due to the large buildup of gases in our atmosphere it is almost impossible for the earth to release heat. The more gases in the atmosphere, the more of the sun’s radiation is absorbed. But the greenhouse effect is not all bad, it is actual vital for the survival of life on earth. Without the greenhouse effect all of the sun’s heat would be released into space and it is estimated that the earth’s Average temperature would be roughly negative eighteen degrees celsius.3 It is only the increasingly large amount of greenhouse gases being pumped into our environment by humans that it is causing a problem.  This is significant because it explains why pollution, and in particular the release of greenhouse gases, can increase the global temperature. This clearly shows, in a scientific way, the correlation between pollution and global temperatures rising.
Humans are responsible for the large buildup of greenhouse gases in the our environment. According to the book, “Earth’s Changing Environment” the most prominent greenhouse gases are carbon dioxide, methane, nitrous oxide and halocarbons. Humans are major producers of all four of these gases. For instance, carbon dioxide is released during the burning of fossil fuels (coal, oil, natural gas, electricity generation, transportation, industry, deforestation, etc.) Carbon dioxide in the atmosphere increased 35% during the industrial revolution. Methane, which is twenty five times as powerful at trapping heat than carbon, is produced by the raising of livestock, rice cultivation, the use of fossil fuels and decomposition in landfills. Decomposition of landfills, agricultural and industrial processes alone have more than doubled the atmosphere’s levels of methane.3 Nitrous oxide, although much rarer than carbon dioxide and methane, is three hundred times as powerful at trapping heat than carbon dioxide. Human causes for the release of Nitrous oxide include fertilizer use and fossil fuel burning. Another greenhouse gas is halocarbons. Halocarbons are extremely rare, and almost never found in nature. But, although rare, halocarbons are ten thousand times as powerful at trapping heat as carbon. Halocarbons are almost completely absent it nature, but they are quite commonly found in refrigerants, insulation, aerosol, propellants and cleaning solvents. According to the article “Climate Change Could Be Devastating and People Must Adapt to Survive”, there is scientific evidence that emissions from automobiles, power plants and deforestation is causing our planet to warm. It is not coincidence that the carbon dioxide levels in our atmosphere are the highest they have been in the last six hundred and fifty thousand years. This shows that humans are responsible for the large buildup of greenhouse gases in our atmosphere, and there is no denying it. It is important that we all understand what greenhouse gases are and how we create them so we can be conscious of how our everyday actions can affect the environment.  ...

Effects of Global Warming Essay

1168 words - 5 pages .). This essay will examine the main effects of global warming by looking at the threats to wildlife and habitat, rise in sea level, and health impacts on humans. One main effect of global warming is the threat to wildlife and habitat. The increase in global warming disrupts wildlife species and causes extinction to animals that cannot adapt (NRDC, n.d.). One example is the decrease in polar bear population. As the ice continues to melt

But more warming is already on the way, only delayed by the great inertia of the world ocean. The Earth already has the components for a global cataclysm, due to our unchecked greenhouse-gas, carbon dioxide, and methane emissions which may lead to a devastating, fatal outcome by the deterioration of our ozone layer and the icy cold temperatures as the outcome of the entire world’s ice being melted.
