Paleoclimate Data - 1728 Words

Is the atmosphere of our planet warming consistently, and at a more rapid pace than ever before, and is it being caused by human consumption? This question is the basis for the dispute on Global warming. It is this century’s largest debate. There are scientists, politicians, and civilians on both sides of the debate. Scientists have determined that the Earth has cooled off and warmed up several times over its long history. I do not believe that a reasonable person would deny that there is the potential for the Earth to repeat this pattern at some point in the future. The real point of contention is then in reference to the cause. Some scientists believe they have found a correlation between an increase of carbon dioxide in the atmosphere†¦show more content†¦Any good pediatrician will tell you that a mild fever is the body’s way of healing itself. You shouldn’t rush in with Tylenol to lower a fever of one hundred degrees Fahrenheit or less. If our bodi es work this way who is say that the Earth isn’t operating on a similar system? Scientists began to search for additional information, older information, which would lend credence to their theory. This information is known as proxy data. Proxy data exists in tree rings, ice cores, sediment cores, historical data, fossilized pollen, and coral (i). This data is not a direct indication of carbon dioxide or temperature, but a study of elements that have existed on our planet long before the wide usage of instruments to record information. Utilizing a variety of statistical means to arrive at their conclusions scientists compiled this information in support of the theory of climate change. Ice that has been drilled out of the depths of Antarctica and Green land can date back 800,000 years. The air bubbles found here show an increase in atmospheric carbon dioxide. The graph below compares the levels of carbon dioxide and the estimated temperatures gathered from the proxy data of t he ice core. The statistical manipulation indicates that in 8000,000 years the Earth has never seen the levels of carbon dioxideShow MoreRelatedGlobal Warming Essay example699 Words   |  3 Pagesridiculous. Bruce Thompson, an engineer, did an experiment to reveal if the climate data used to predict global warming is reliable. He had Roy Spencer make a map of all the locations that record temperature at least four times a day or more. (See appendix 3) He noticed that there are no sites that collect data on the 70 percent of earth that is ocean. So only 30 percent of earth’s has the very few sites that do collect the data. Most of the sites are in the northern hemisphere so that could alter the resultsRead MoreMy Graduate Career At Mount Holyoke College998 Words   |  4 Pageschange in stratigraphy within sediment cores in Marblehead, Massachusetts. I am responsible for using her previously gathered XRF-scanner data to determine the paleoclimate immediately following the g lacial maximum about 14,000 years ago. I also have access to data showing the core’s magnetic susceptibility and organic matter content. Through the analysis of this data, I hope to determine the levels of chemical elements, associated with a marine setting, that are present in these sediment cores. My primaryRead MoreClimate Change : Global Warming875 Words   |  4 Pagestemperature (Spencer Weart American Institute of Physics, 2015). To explore how climate conditions have varied throughout Earth history, paleoclimate reconstructions are used to extend records back hundreds to millions of years (IPCC 2013, pg.2). Long term changes in global climate patterns and variability have been reconstructed through the amalgamation of paleoclimate reconstructions and comprehensive and diverse sets of observations (IPCC 2013, pg.2). These unprecedented observed changes record thatRead MoreClimate Change : Past, Present, And Future2187 Words   |  9 PagesEnvironmental Change: Past, Present, and Future Improving Future Climate Modeling Using Paleoclimate Data and Investigating To Effects On Water Resources Introduction The purpose of this paper is to contemplate the use of information and all the knowledge gained from this class in regards to my work on climate change effects on water resources. Specifically, my purpose is to search for knowledge and data from paleoclimatic evidence that will allow us to make better future climate projections forRead MoreVostok Ice core report922 Words   |  4 Pagesglobal mean temperature. Introduction: This report is written to summarize the findings of the Vostok Ice-core lab, based on the data obtained in the ice-core. It mainly addresses the relationship between the composition of ice core and temperature change. Moreover, the controversy of main reason of global warming will be discussed. Method: In this report, the data is obtained from the Vostok core drilled in East Antarctica, at an altitude of 3488m. The ice core has a total length of 2083m. InRead MoreUsing Paleomagnetic Data For The World s Landmasses Of The Late Triassic Early Jurassic1389 Words   |  6 Pagespaleomagnetic data for the Late Paleozoic time, inconsistencies are present which suggest a very different Pangea construction. These inconsistencies are seen in Late Paleozoic paleomagnetic data apparent polar wander paths (APWPs) for Laurussia and Gondwana. To fit Wegner’s Pangea reconstruction, the APWPs suggest a substantial crustal overlap and shearing (Domeier et al., 2012). This paper looks to review proposed alternative reconstructions for Pangea, using paleomagnetic data as the quantifiableRead MoreThe Effect Of Temperature Increases Due On Anthropogenic Warming Change The Probability Of Precipitation Deficits That Cause Severe Drought Conditions?

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 has doubled, without any significant change in the trends of precipitation variabilityRead MoreClimate Analysis On Climate Archives1612 Words   |  7 Pagesanalyzing ocean water pH levels however, there are some problems with using it as a proxy. For instance, sample availability especially when analyzing boron within foraminifera, then high accuracy and precision must be maintained when obtaining data otherwise the data collected will not be meaningful (Pelejro and Calvo, 2007). The past climate can be studied using corals as a climate archive however, there are some proble ms with using the proxies that need to be further investigated. Foraminifera, alsoRead MoreEssay on Global Warming and Greenhouse Gases1265 Words   |  6 Pagesimportant to consider other data that is part of the climate system along the line of time and space. Some other sources of information are: tree rings, bore hole temperature measurements in the soil, permafrost, and ice sheets, and measurements of the mass of valley glaciers and ice caps. By looking at this material for the past 600 years it has been determined that the warming in the twentieth century is greater over this time period (Briffa). From paleoclimate studies it has been concludedRead MoreEssay on How Should We Respond to Global Warming?1758 Words   |  8 Pagesthan I had anticipated. Initially, I hoped to find specific information which answered the questions of global climate variations and mankind’s influence upon climate systems. Yet, in digesting several different views, variables, data, satellite data, and proxy data, I only found that my discombobulation had lots of company. It seems nobody definitively knows, or can agree on, where long-run climate change is heading or what the effects will be on different ecosystems, or even whether increased
