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

People are responsible for higher ampere-second dioxide atmosphere emissions, while the domain is now into the Little screwb either Age, or near behind it. These factors together cause many years discussions of the master(prenominal) sources of climate changes and the temperature increasing as a result of human been or natural changes and its consequences even if its lead to the global change, or to the existences cooling. In their articles, Global Warming Is Eroding Glacial 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 right that global change is taking place. Significant increase of carbon dioxide in the atmosphere is due to human activities combined with natural factors such as volcanic emissions and solar radiation all together they lead to climate changes and temperatures rising. At the aforementioned(prenominal) time, other factors such as deforestatio n contribute to environmental changes for whatsoever 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 last few decades the Earth is experiencing greater rate of rising temperatures due to greenhouse gases that are creation produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the National Academy of Sciences stated There is no doubt that the Earth is warming, also he added that hatful are at least partly responsible for these changes in supplement to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several(prenominal) million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial Revolution has begun (Revkin 340). Of course, it is unf air to interpret that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relative to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a result 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 assiduousness of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer consumption (Lindsey, par.
