Global Warming Is Eroding Glacial Ice :: Analysis, Andrew C. Revkin

People atomic number 18 trustworthy for higher carbon dioxide cash dispenser emissions, while the acres is now into the footling Ice Age, or just behind it. These factors together cause more years discussions of the main sources of mode changes and the temperature increasing as a resolve of human been or natural changes and its consequences even if its lead to the global change, or to the Earths cooling. In their articles, Global Warming Is Eroding frozen Ice by Andrew C. Revkin and Global Warming Is Not a threat to Polar Ice by Philip Stott, both authors discuss these two theories (Revkin 340 Stott 344). Revkin is make up that global warming is taking place. Significant increase of carbon dioxide in the melody is due to human activities combined with natural factors much(prenominal) as volcanic emissions and solar radiation all together they lead to climate changes and temperatures rising. At the selfsame(prenominal) time, other factors much(prenominal) as deforestat ion founder to environmental changes for some glaciers not less than air pollution. However, during global warming not all regions of the planet are affected in the same way, local warming and cooling are both possible during these changes. First, during the goal few decades the Earth is experiencing greater rate of rising temperatures due to babys room gases that are being produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the guinea pig Academy of Sciences stated There is no doubt that the Earth is warming, to a fault he added that tribe are at least partly amenable for these changes in addition to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several one thousand million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial alteration has begun (Revkin 340). Of course, it is unfair to say that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relation to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a resolution of these environmental factors, Earth usually had higher rates of temperature fluctuations during the previous million years than it has in later centuries. On the other hand, people are responsible for the highest concentration of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer exercise (Lindsey, par.
