Anthropogenic

Abstract The purpose of this article by Diffenbaugh et.al. is to determine how temperature increases due to anthropogenic warming change the probability of precipitation deficits that cause severe drought conditions, and determine what the conditions will look like in the future. They used historical precipitation and temperature data with Palmer Drought Metrics and global climate models to attempt to answer this question. It was found that in the past twenty years, the frequency of drought years

Samantha Ballard 470 Climate Project Anthropogenic Emissions in the Ocean Anthropogenic emissions affect the atmosphere, ocean, biosphere and cryosphere. These components of the climate system create interactions between each other ranging from a synoptic to microscale including everything in between. Ever since the industrial revolution, human-produced emissions have been changing the world around us. The phenomenon of having greenhouse gases and aerosols in the atmosphere is natural and necessary

Global Climate Change Marc E. Wiltfong SEC 510 – Position Paper 1 Faculty: Dr. Danielle Camacho Southern New Hampshire University Date: February 05, 2017   Global Climate Change Summary of the issue: Is climate change caused by mankind or is it simply a natural occurrence? If the answer were as easy as “yes, it is 100% caused by humans,” or “no it’s not at all caused by humans,” there would be very little room for argument. Two questions need to be investigated: 1) Is it probable that such a young

different geographical concepts. The two concepts I enjoyed learning the most and feel are of most importance to me is the concept of anthropogenic changes and volcanoes. The first and of utmost importance is the term Anthropogenic. Before entering into Living Physical Geography I had never even heard of the word. At the beginning of the class I learned that anthropogenic means created or influenced by people. It was the very first definition I wrote down on the very first day of class. At the first

Physical Geography This section will analyze sinkholes from a broad perspective and then hone in on Florida sinkholes. The term “doline” is the preferred scientific and international term, which is synonymous with “sinkhole,” but because it is widely known and used in America, the term “sinkhole” will be retained during this study. In this paper, the term “sinkhole” refers to a depression caused by the solution of limestone. In brief, sinkholes form when the land surface above collapses into subsurface

drain wetlands, reroute surface runoff into aquifers, and detrimentally impact natural ecosystems by significantly altering them. Sinkholes occur naturally in Florida, but anthropogenic activities can influence their formation. Indeed, this paper will argue that groundwater pumping and surface loading are the most critical anthropogenic factors that influence sinkhole development in Florida. According to Tihansky (1999), “Although many new sinkholes

live in an age where most environments on earth have been impacted by anthropogenic activities. Chapin III et al (2001) contend that, “humans have been a natural component of most ecosystems for thousands of years” (p. 14). Humans interact with the environment in many ways: landscape modification, agricultural activities, urbanization, urban sprawl, carbon dioxide (CO2) emissions, stormwater runoff, and so forth; these anthropogenic activities can have detrimental environmental results.

orbit and organic carbon which reflect sunlight. Global warming and climate change are not to be confused because global warming is caused mainly by anthropogenic factors like the emission of carbon dioxide gas and use of fossil fuels whereas climate change is completely natural, however, according to Milan Radovanovic, “it is clear that the anthropogenic factors dominate the increasing temperature and the natural ones have the maximum influence…” (Radovanovic). Therefore, “the contribution to global

differences between AR3 and AR5 I noticed three main differences in the summaries. First one being the length of each of them. The length of AR5 is a lot longer than that of AR3. In AR3’s summary it goes more in-depth on the information about Anthropogenic greenhouse gases and the issue itself. Now looking at the wording that is used to describe the different variation of what has happen to our climate over the years it has changed from words such as “likely as not” or “likely” to wording such as

distinct environments. Furthermore, the researchers determined that anthropogenic forcing impacts have resulted in longer periods between extreme cold temperatures for the observed 20 years (Christidis et al. 1929). When examining global temperature changes, the impacts of major greenhouse gases must be considered. A study conducted by Kaufman et al. investigated the effects of greenhouse gases on forced and natural anthropogenic factors (11790). The authors utilized a statistical model technique
