Global Warming Global Warming

Global warming is the environmental and social changes caused by emissions of greenhouse gases. Human activities have been the primary cause of this significant change, resulting with extreme weather conditions, increasing sea levels, and climate changes. In this paper I will compare and contrast natural versus anthropogenic climate changes of global warming, mitigation strategies, mitigation effectiveness, policy implications, costs, and address some policy changes to help stabilize global climate.

Global warming is one of the most controversial topics in the world today. Global warming describes a condition where the average temperature of the earth’s atmosphere and oceans increase. Global warming is predicted to have significant harmful effects on life on earth. The controversy arises from conflicting evidence in the scientific community as to whether humans are contributing to global warming, whether it is a result of natural forces that are beyond the control of humans, or in some cases, whether it is even occurring at all. This research will examine credible evidence of global warming and will explore its causes and

The first argument examined on the man-made global warning side is that increasing greenhouse gases caused by human activities is causing directly observed climate changes. The first resulting climate change discussed is warming global surface temperature. There has been an increase in global surface temperature of 0.74 degrees C since the late 19th century. In the last 50 years alone the temperature has increased by 0.13 degrees C per decade. North America and Eurasia have seen the largest increase in warmth. However, some areas of the earth have actually cooled some this past century (Easterling & Karl, 2011, para6). After the mid 20th century 70% of the global land mass saw reduced diurnal temperatures. From 1979 to 2005 the maximum and minimum temperatures have shown no change; both indicate warming (Easterling & Karl, 2011, para10). Furthermore, borehole temperatures, snow cover, and glacier recession data all seem to agree with recent warming (Easterling & Karl, 2011, para11).

Climate change is a threat that has been in existences for years, but appears to be a greater threat to the world currently. According to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, there is more than 90 percent certainty that emissions of heat-trapping gases from human activities have caused “most of the observed increase in globally averaged temperatures since the mid-20th century” (IPCC, 2007).

Climate change is a global issue that is under an endless debate for its causes. The increase in the global mean annual surface air temperature in the previous century by 0.75C (IPCC 2007) in coincidence with the excess of the carbon dioxide (CO2) concentrations in the atmosphere from 289 to 353 ppm (Lean et al. 1995) by burning fossil fuels support the human-induced hypothesis of climate change. On the other hand, the protestors of the natural origin of climate change build their argument on the variations of solar radiation and volcanic activities (Rind and Overpeck 1993). Meehl et al. (2005) report that the global warming will continue in this century, even if the greenhouse gasses are stabilized. This reveals that the climate change is

Despite the controversy that surrounds the existence of climate change, there is a high agreement among scientists that human-caused climate change in very real. Over the past two decades, surveys and studies have been done on climate change and the results have shown that the average global temperature has increased by about 1.4 degrees Fahrenheit. The sea level is also rising and heat waves are happening more frequently than before. These events could lead to an abrupt and potentially irreversible climate change but scientists do not know the tipping point for such an event. Therefore, the sooner the inhabitants of earth begin to take action against climate change, the less likely something irreversible could happen.

The first section of this paper establishes what exactly naturally occurring climate change is. What are the underlying causes? What happens when climate change occurs? Most importantly how do we know this? The second section of this paper seeks to use our new found knowledge of natural climate change. It builds upon the premise of the first section and the ideas introduced there. Since we know the natural causes of climate change we can draw conclusions relating to the impact and influence that humanity is having on climate change. It is by first establishing naturally occurring climate changes legitimacy and causes and then linking these causes to our now current anthropogenic climate change This second section is also the more controversial, nobody disputes naturally occurring climate change, but as soon as causation is assigned to humanity and particular sections within; it becomes a vigorously debated topic. By first establishing climate change as a naturally occurring

People have been aware of the rise in the earth’s temperature and its effects however, many persuaded themselves that there was really no immediate danger as well as, there was nothing one could do to mitigate the issue and felt higher authorities were responsible for outcomes and resolutions (Wearts, 2011). On the contrary there is immediate danger and long term affect to our earth if our earth’s temperature continues to rise. Polar caps and glaciers will melt resulting in major changes in our ecosystems and causing the sea level to rise (McKibben, 2009). Anthropogenic Climate Change has caused the uprising of precipitation intensity and or dry spells, and wind patterns (Giorgi, Coppola, Diffenbaugh, Gao, Mariotti & Shi, 2011). Precipitation intensity up rises due to the increased atmospheric water holding volume. The increase is related to surface evaporation rates ultimately,

The article, Global Climate Change Triggered by Global Warming by Stuart D. Jordan, seeks to provide evidence that global climate change caused by global warming is currently in affect and requires immediate attention and action. Jordan claims that the Earth’s climate has been undergoing significant and alarming changes for the past thirty years. He provided evidence based on observations, theoretical models, and calculations made by other researchers.

In the last 100 years, Earth’s average temperature has risen by 1.4°F. The rising global temperatures have caused changes in weather and climate. Global warming refers to the ongoing rise in the average temperature near Earth’s surface. This is causing a climate change, which refers to any significant change (major change in temperature, precipitation, or wind patterns) in the measures of climate lasting for an extended period of time (several decades or longer). Due to this, it is projected that the temperature will rise from 2 to 11.5°F in the next hundred years (US EPA, 2014). The “drivers,” which are the principal causes making this occur, are very controversial. It is debated whether a change in temperature is due to the work of

A great deal of chapter nine in our book, Discovering Physical Geography, discusses the various climates that exist within our world. As the chapter goes on, the book explains the past climate changes due to the numerous fluctuation in Earth 's average temperature. One well known theory, the Milankovitch theory, explains that the fluctuation of Earth 's temperature are due to the "long-term variations in Earth 's orbital eccentricity, tilt, and axial precession," (Arbogast 236). In our present day, the vast majority of climate scientists agrees that the world is warming and believes it is mainly caused by humans influence and their association with the greenhouse gases (Arbogast 239). In this paper, I will examine the connection between human-induced global warming and its global effect on Earth 's climate, and what it may yield to the future of those living on Earth.

The major threat of today’s world is global warming. Due to various reasons global warming turns out to be a serious issue in the last few years. Today people believe in global warming while this concept was not so much believed and people interpreted in some other meanings what was happening in the past. Global warming is amplification in the temperature of earth because of industrial pollution, fossil fuels, and agricultural practices caused by human being, other and natural gas emissions. Because of this greenhouse gases are released in large quantity. Solar radiations of short wave type go down under the earth and increase its surface temperature, while infrared radiations of long wave type that is released by earth

Through the eyes of most scientists, global warming is seen as a very serious and severe threat. The actions taken by humans, such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad.

Global warming is an important issue for humans to consider and science to figure out. Personally I don’t care very much about global warming and have never been active in green movements. The evidence presented in this class is very informative and useful when taking into account the numerous known and unknown causes and cures for global warming. However, my attitude towards global warming is unchanged.

İnsanlar tarafından atmosfere salınan gazların sera etkisi yaratması sonucunda dünya yüzeyinde sıcaklığın artmasına küresel ısınma deniyor. Daha ayrıntılı açıklamak gerekirse dünyanın yüzeyi güneş ışınları tarafından ısıtılıyor.
