Global Warming. Global Warming Is An Increase In The Earth'S

Global warming is, in essence, term for the observed century scale rise in the average temperature of the earth’s climate and its related effect.(wiki) The greenhouse effect is mainly because the modern industrial society burned too much coal, oil and natural gas, the fuel combustion after release large amounts of carbon dioxide gas into the atmosphere. Carbon dioxide is the function of heat absorption and heat insulation. It

an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. “http://www.dictionary.com/browse/global-warming”

The definition given by NASA of global warming is “the average global surface temperature increase from human emissions of greenhouse gases.” On the subject of global warming, the key terms that applies is greenhouse gases. The title “greenhouse gas” comes from the idea that the chemicals that people use to run a greenhouse are also very common in our own atmosphere. A few of these chemicals include carbon dioxide and methane. Global warming is mainly caused by an excessive amount of greenhouse gases and creates environmental problems that affect not only temperatures, but can also disrupt many animal habitats and their way of life.

“Global warming refers to the recent and ongoing rise in global average temperature near Earth 's surface. It is caused mostly by increasing concentrations of greenhouse gases in the atmosphere. Global warming is causing climate patterns to change. However, global warming itself represents only one aspect of climate change” (Climate Change, EPA.gov).

Earth’s climate system has been experiences changes during the last century. Dating back in 1859 a Swedish scientist named Svante Arrhenius was the first to claim that fossil fuel combustion eventually resulted to the contribution of global warming. According to S.M. Enzler MSc, in his article “History of the Greenhouse Effect and Global Warming”, published by Lenntech, Dr. Arrhenius’ findings were long forgotten, “At that time it was thought than human influences were insignificant compared to natural forces, such as solar activity and ocean circulation. It was also believed that the oceans were such great carbon sinks that they would automatically cancel out our pollution.” (Enzler 1.). Global Warming was just an illusion up until the mid-1900s a scientist named Gilbert Plass began experimenting with carbon dioxide which he soon concluded that adding more carbon dioxide to the atmosphere would intercept infrared radiation, that is otherwise lost to space, thus warming the earth. Dr. Plass’ conclusion is very similar to that of Dr. Arrhenius, and the reason why it was not overlooked was due to the advances in technology during Dr.Plass time, proven to have a more accurate data compared to the past. Further research was conducted to help explain the rise in the global annual mean temperature. As of 1988 it was finally acknowledged that climate was warmer than any period since 1880. I agree that

Global warming is the name given to the increase in the earth’s surface temperature. It is caused by the collection of greenhouse gases, carbon

Due to recent increases in the Earths average temperature Climate Change has become a highly discussed topic in society. This has caused individuals to solely focus on the increasing temperatures of today and completely neglect temperatures that the planet has experienced in the past. When looking at paleoclimate data one can clearly see the fluxuations in the ice age cycles (periods of cooling and warming). Ice age cycles are amplified by positive feedback systems that make the earth cooler or warmer depending upon the physical process that is being altered. In his response Bruce Parker, a physical oceanographer, discussed the impact that these positive feedback loops have on Earths overall temperature and how scientists have yet to figure out what causes the amplifying mechanisms to switch from warming to cooling.

According to the EPA, in 2012, U.S. greenhouse gas emissions totaled 6,526 million metric tons of carbon dioxide.The greenhouse gasses absorb and radiate the energy of sun trapping heat in the atmosphere. Furthermore, CO2 stays in atmosphere for many years. From the figure above, there were increase in the concentration of CO2 present in the Earth's atmosphere from year1750 to 2000. (NASA graphs by Robert Simmon, based on data from the NOAA Paleoclimatology and Earth System Research Laboratory.)Although there were fluctuatian over the years, the average temperature is still rising. (NASA figure adapted from Goddard Institute for Space Studies Surface Temperature Analysis.) Hence the temperature of the Earth can seem to increase with the rise of the CO2

The planet naturally goes through periods of extreme cooling and heating. That’s why we have had multiple periods of ice age (when polar ice grows far beyond its normal range) and the opposite, hothouse periods (when all the polar ice melts). Currently, we are in an interglacial period (when it’s not too hot nor too cold). Interglacial periods are best for human life because our bodies have not evolved to withstand radical high or low temperatures.

Researches reveal that natural events as well as human related activities contribute to changes in average global temperatures. AtKisson affirms that global warming is basically a result of increased emission of greenhouse gases into the atmosphere. This atmospheric carbon dioxide (co2) comes from anthropogenic (caused by humans) sources. The concentration of greenhouse gas carbon dioxide, nitrous gases, and methane in the atmosphere has increased evidently due to human activities since 1800. NASA’s article adds:

Let us look at what we know. Over the years, the globe has fluctuated in temperature. We have had ice ages and warming periods. We all learned in our history books, natural forces continue to dominate the climate today as they did in the past. The Medieval Warming Period in the 1200s was somewhat warmer than we are now. During the early part of the twentieth century the climate started to warm from 1910 until about 1940. After 1940, the climate began to cool for about 30 years. Then, in a very similar time span and temperature level in the 1910-1940 warming, another warming

Over the last 50 years, Human activities –particularly the burning fossil fuels have released sufficient quantities of carbon dioxide and other greenhouse gases to trap additional heat in the lower atmosphere and affect the global climate.

Merriam-Webster defines global warming as an increase in the Earth 's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting

Global warming is when the increase of the Earth’s surface temperature. There are many factors that contribute to global warming. Global Warming is a global issue that according to livescience.com “is when the gradual heating of earth’s surface, oceans and atmosphere.” Many of these things about global warming and that contribute to global warming many people are unaware, for instance, the cause and effect of global warming, how it affects the United States on a national level, and a local level.

Global warming has become a well conversed topic among scientists and peoples in the world today. There are extremists who do everything possible to stop contributing to the warming, but the average person does little to alleviate the issue and in many cases refuses to acknowledge that there is a problem at all. Dating back to millions of years ago, even before humanity was born, the world has always experienced one form or another of warming; so the warming seen today is not as bizarre as many may think. The prevalent saying that history often repeats itself, is no joke when discussing global warming. As to what is kindling the current warming, that is where a query is imposed. Scientists from around the globe have theorized close to every possible contributor to the warming seen today, and the conclusion that present occurrences of global warming are being evoked by human interference has become evident.
