Introduction From man’s basic understanding of existence, he acknowledges that his presence is but a fraction in time in relation to the longevity of the Earth’s existence. This attests to the time period in which the Earth functions. Man’s calculations of year to year changes in the Earth’s atmosphere are meager at best in determining the cycle for such an entity. Man’s oldest data dating back from ice core samples from Antarctica can not trace back further than a minute percent of the history of the billions of years that the Earth has existed. (Relatively) recently, Earth has endured "naturally occurring" Ice Ages, meteorological disasters, and the evolution of man and his technology. So the question is raised, is mankind bold in thinking that anything it does collectively will scar the Earth beyond repair? Man might change the Earth’s surface, man might obliterate his own existence, but man will not change the propensity for nature to allow the continuation of life. Debate on Global Warming So, what is man doing for mankind? There is a general concensus that one of the greatest dangers man is imposing upon himself is that of a global change in the atmosphere, causing the average temperature on Earth to increase. Before any discussion can begin on how to go about fixing the problem of global warming, it is improtant to point out that the problem is more basic than otherwise understood. The problem is not global waring, it is how to deal with the possible existance of global warming. First, let us consider the assumed temperature change. What real facts are we using to conclude that a global temperature increase is happening? Second, consider the possible reasons for a temperature change. Is man the only possibility? Third, assuming the chance for man to be the cause in a real global temperature average increase, is this a situation that we should try and label a problem? Is change always bad? The amount of data that is accessible and relavant to this this debate can be interpreted in a variety of different ways… Go on and surf the World Wide Web. You may find convincing arguments on both sides, but that is just it, they are arguments. Models have been constructed, theories have made predictions, and more. What do we know? We know that the evidence is inconclusive and more research should be done. Explorations on the corrolation between fluctuations in solar activity and Earth’s temperature changes should be furthur endeavored, expirimentation with simulated Earthly atmospheres should be enhanced, and U.
For instance, at the turn of the 20th century the Earth was very cold. During the first decade of the 20th century the Earth was at it’s coldest it has been in the last 11,300 years. Now however, during the first decade of the 21 century the temperature is hotter than seventy-five percent of the last 11,300 years. If not made for man-made influences, the Earth would be in a very cold phase right now and getting colder (Brumfield). This clearly shows that as the years went by man has had a profound effect on the Earth’s climate. If we do not try to change the way we live, then future generations will be living in a completely different world than ours.
The text also assumes that the earth has been stable throughout most of human history. On a large scale this is certainly true, when one considers that “the temperature has barely budged; globally averaged, it’s swung in the narrowest of ranges, between fifty-eight and sixty degrees Fahrenheit,” and that weather has been predicable with only “freak storms, disturbances” (McKibben 2010, 4). This doesn’t take into account the vast changes humans have caused on more local levels. Changing our environment is a defining attribute of human beings that shouldn’t be completely overlooked. This bypassing of humanity’s impact on the earth is partly due to the fact that McKibben, understandably, views the issue of global warming through a very human lens.
A man named Robert Laughlin once said, "The Earth is very old and has suffered grievously: volcanic explosions, floods, meteor impacts, mountain formation and yet all manner of other abuses greater than anything people could inflict. Yet, the Earth is still here. It's a survivor." Laughlin clearly believes in this quote that the Earth can take care of itself. The Earth has been through worse disasters than just pollution, and extinction of species and plants. Roderick Nash, an environmentalist and activist, says otherwise.
Over the past years, planet Earth has been warming up. According to NASA's Goddard Institute for Space Studies, average temperatures have risen around1.4 degrees Fahrenheit/0.8 degrees Celsius since 1880. In fact, the rate of warming is increasing. It was reported by a number of climate studies that the last two decades were the hottest in 400 years. Global warming is a major threat to the planet. It is agreed that humans have caused most of the past century's warming by releasing greenhouse gasses, as we power our electronic lives. The “greenhouse effect” is performed when the gasses let out into Earth’s atmosphere trap heat from the sun. Through the burning of fossil fuels, humans are enhancing the greenhouse effect and increasing the temperatures of the planet. Although the greenhouse effect is what keeps the planet warm, thereby supporting life, too much would also result in severe issues. Now, with the increasing rate of greenhouse gases emissions, frozen glaciers are melting, sea levels are rising, and wildlife is scrambling to keep up with the fast pace. Above that, weather can also become more and more extreme. Something has to be done.
Man has believed, for most of his existence, that the earth was only a few thousand years old. But a new theory surfaced in the 19th century called "Uniformitarianism". This is the belief that nature can be explained by natural causes.
In just the last fifty years, humans, namely Americans have virtually remodeled the Earth and everything on it. We have changed its landscapes, wind patterns, migration routes, and weather; diminished its greenery and killed its animals. Nature did not seem a force that could be controlled and yet it has been. We are conducting an inadvertent global experiment by changing the face of the entire planet. We are destroying the ozone layer, which allows life to exist on the Earth's surface, clearing the majority of the earth’s forests, and disrupting countless ecosystems. The result has been an unfavorable alteration of the composition of the biosphere and the Earth's heat balance. If we do not slow down our use of fossil fuels and stop destroying the forests, the world will become hotter than it has been in the past million years. This warming will rearrange entire biological communities and cause many species to become extinct.
One of the first major pillars of the evolution theory that falls away under close scrutiny is the concept of an 'old earth.' Because the evolutionary process needs millions and millions of years in order to take place, evolutionists declare that the earth must have existed for 4 to 5 billion years. However, with all things considered, this theory is simply impossible. Three astronomic facts disprove it almost immediately: the recession rate of the moon, the dissipation of the earth's magnetic field, and earth's rotation rate.
Many of the scientists believe that earth is getting hotter, and the average temperature of earth is increasing each year due to the excessive burning of fuels on earth. The idea that the earth’s temperature is increasing is called global warming, and humans are the main cause of it. In spite of this theory, many believe that there is no global warming because the surface temperature has not increased steadily, but documents and researches show that global warming is real, and it is endangering lives of the animals on the earth.
Climate change occurs when there is a significant variance in the climate which last for several decades or longer and not for a short period of time. Climate change includes changes in elements such as temperature, precipitation and wind patterns.
of humans. Rising global temperatures have been caused by the changes in weather and climate,
Many change and influences are being been concerned since average temperature has changed. While global warming is occurring, global temperatures and climate patterns are changing across the entire world. That some effects started appearing across a spread of countries is a result of human activities such as burning of fossil fuels, deforestation, and agriculture result in climate change all of the problems can be addressed by reducing energy consumption, curbing clear logging, and eating less meat.
Climate change is evidenced through shifts in the weather patterns such as winds, humidity and temperatures over certain durations. Natural climate changes occur less frequently and they are triggered by factors related geographical aspects as well as solar radiation. The earth’s movement on the orbit triggers changes in climate causing some areas to have higher temperatures than usual while others are significantly cold depending on the position of the earth on the orbit. The heat form the sun causes changes on the stratospheric ozone and it increases the amount of greenhouse gases. Heat from the oceanic crust also contributes to warming as a result of episodic hydrothermal venting (Liao & Sandeberg, 2012). Volcanic activity also causes a release of certain elements that may block the sun and also contribute to increase greenhouse gases in the atmosphere.
Climate Change can result from both natural events and human activities. Some examples of natural causes of climate change are volcanic eruptions, ocean currents, solar variations, and earth’s orbital changes. Some examples of human activities are fossil fuels, warming of temperature due to industrialization, and deforestation of tropical rainforests. Factors of climate change can change and vary naturally over time. The issue of the fast increase in earth’s temperature over the past years is one of global importance and disputed origin. All these justifications are for the change in the earth’s temperature are valid, however, there is a reason to believe that human activity and carbon dioxide emissions are a great part of the cause for the
An environmental effect of global warming is the fact that higher temperatures will lead to
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased evacuation of greenhouse gases. “Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface while long-wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.” (2)
