The Warming of the Earth The of global warming, has been intensely debated amongst many in the world community for decades. Debates in regards to the degree which global warming has been and continues to be occurring throughout the world. Regardless of individual perspective as to how the warming has occurred, the evidence is insurmountable, that the world is warming at a continued rate, with drastic implications for the future if the warming continues. "The main cause of this global warming appears to be the greenhouse gas CO2, whose concentration has been increasing primarily due to the burning of fossil fuels and to deforestation. However, in recent years, increasing concentration of other greenhouse gases, such as Methane (CH4), nitrous oxide (N2O), and chlorofluorocarbons (CFCs), has collectively been shown to have an effect almost equal to that of CO2," (Ahrens, p.42).
With the millions of people that call Earth 'home', the condition of the planet is one that many have sought to gather more information about, in order to understand the degree in which the planet may be in peril, as well as to what degree human actions would be responsible for it. "Throughout Earth's history, the climate has varied on many time and space scales. In that sense, climatic change is not new, and humanity has had to adapt to a constantly changing climate. Human action has itself had an impact on that climate. Until recently, the impact was local, but now there is concern that human activity, primarily through the emission of greenhouse gases into the atmosphere, is leading to a world-wide climatic change which is more rapid and more extreme than any encountered during human history," (Robinson & Henderson-Sellers, p.267). While the extent at which the climate of the planet has varied, so has the impact of its inhabitants. As humans increase their usage of such resources, the rate of global warming is steadily increasing, in conjunction with such behavior patterns.
As is the case with many discussions, there are those who feel that the Earth is not warming to such catastrophic levels, that many in the science community have come to believe. According to a speech given by John Coleman, the founder of the Weather Channel, he seeks to explain the warming trend by saying, "Through all history, Earth has shifted between two basic climate regimes: ice ages and what paleoclimatologists call "Interglacial periods." For the past 10 thousand years the Earth has been in an interglacial period. That might well be called nature's global warming because what happens during an interglacial period is the Earth warms up, the glaciers melt and life flourishes," (Coleman, p.1).
Consequently, to remain inactive on the issue of global health, would mean results that would not bode well for the longevity of the planet itself. "In its final and most powerful report, a United Nations panel of scientists meeting here describes the mounting risks of climate change in language that is both more specific and forceful than in previous assessments, according to scientists here. Synthesizing reams of data from its three previous reports, the United Nation's Intergovernmental Panel on Climate Change for the first time specifically points out important risks if governments fail to respond: melting ice sheets that could lead to a rapid rise in sea levels and the extinction of large numbers of species brought about by even moderate amounts of warming, on the order of 1 to 3 degrees," (Rosenthal, 11/17/07).
The text Life: The Science of Biology states the following, "Scientists predict that, as a result of human activities, average temperatures in North America will increase 2 degrees Celsius-5 degrees Celsius by the end of the twenty first century. If the climate warms by only 1 degree Celsius, the average temperature currently found at any particular location in North America today will be found 150 kilometers to the north. If the climate warms 2 degrees Celsius- 5 degrees Celsius, some species will need to shift their ranges by as much as 500 to 800 kilometers within a single century. Some habitats, such as alpine tundra, could be eliminated as forests expand up mountain slopes," (Heller et al., p.1234). For animal species, as well as mankind, global warming has consequences both natural, as well as political, that will be felt by those nations that take an inactive stance towards reaching solutions to combat the problem. Only time will tell, just how much the Earth and its inhabitants, will be impacted by the science and politics involved with the issue of Global Warming and its effects.

Is global warming a genuine threat to the planet earth

...? Is global warming a genuine threat to the planet earth? Introduction The phenomenon of global warming is gradually becoming an imminent threat to the living world. The occurrence of global warming has caused key changes in the atmospheric and climatic patterns of the earth. Global warming has caused the rising of surface temperatures by around 1.33 degree Fahrenheit along a period of 100 years ranging from 1906 to 2006. Along the same period the temperature of the Arctic region is observed to have risen by around 9 degrees Fahrenheit (Rosser, 2008, p.171). Further the rise of global warming phenomenon also led to the...

...surface (Blackburn, 2010). The differences among scientists, despite them having valid points, may have stemmed from the presence of greenhouse gases that were definitely absent the past years. These gases trap the heat that bounced from the Earth’s surface after receiving rays of sunlight. Thus, even if we should be approaching ice age, as some scientists might be thinking, the increase in temperature caused by global warming may prevent it from doing so. On the other hand, if we are on ice age, the signs may not have been too visible because the warming effect of greenhouse gases can counteract the cooling effect seen during the ice age (Blackburn, 2010). Obviously, such controversies...

...by the Earth’s bovine population have an even greater impact upon overall CO2 levels than all human activity within any given year. However, this should not be seen to delegitimize the processes whereby humans can provide additional negative impacts upon the global environment. Due to the fact that the Earth is ultimately a closed system, it can only integrate a certain amount of change before negative impacts are seen. As such the Earth’s ecological system might be able to integrate with volcanic eruptions or the methane gas produced by cows; however, further integration of the ever-increasing levels of human CO2 emissions is likely well beyond the capabilities of the system as a whole....

...Planet Earth: Disc There are cycles to almost everything in nature and this is shown in the first DVD of the Planet Earth series; "From Pole to Pole/ Mountains/ Fresh Water". The seasons are a cycle that is brought up continuously throughout every section, whether it is two seasons or four depends on the location. Places that reside along the equator experience only two seasons, one wet and one dry, because they get an immense amount of direct sun exposure. This is because of the way the Earth is positioned; this tilt of the earth's axis is also what is directly responsible for the four seasons of the most northern and the most southern climates. Due to the fact that...

Earth systems

...Earth Systems 2. Explain the difference between ground- level and stratospheric ozone; why has one a beneficial and the other a detrimental role in the atmosphere? In the early phase of the earth’s history, life could only survive in the oceans because the deadly ultraviolet rays of the sun precluded the growth of life on the earth’s surface. These UV rays could not, however, penetrate water, hence, life flourished in the oceans until ozone started forming from oxygen. Ozone, which has a chemical symbol of O3, is a colorless and unstable gas made up of three atoms of oxygen (Butz 376). It occurs in two layers of the earth: the stratospheric layer, and; the tropospheric layer or the ground-level layer. Presently posing a problem... to the...
