Temperature record of the past 1000 years

and the purpose the writer hoped to accomplish in writing it. The purpose of this paper is solely to report the information read in the article. Michael E. Mann is a climate scientist and has been confronted by many climate change skeptics over the years. In the article “Besieged by Climate Denies, a Scientist Decision to Fight Back”, he discusses his position on why he thinks that attacks on science have no place in a functioning democratic society. He also discusses why he believes the “truth” about

the development of Disaster Risk Reduction but this needs to be supported by continued development and investment. 2. Figures Figure Title Page 1.

recently dead to the variation seen in both of the stable isotope records acquired here (Figure 3). The average value of each taphonomic number is not as important as the fact that one standard deviation (represented by error bars) increases from about 0.2 ‰ to 0.8‰ in δ13C values, and 0.3‰ to 0.9‰ in δ18O values as the taphonomic number increases. If this relationship is universal, it represents a significant impact on the records acquired by damaged, fossil or recent shells. As stated in the introduction

rate. As the hours the day began surface temperature would slowly rise and as the day ended the temperature went down. Climate is measured by devices used to track annual variability and climate patterns include thermometers, rain gauges, and stream gauges. 1 year- The forcing factors are the same as 1 day, and how you measure 1 year is the same as 1 day. Days are measured with temperature while years are measured with how much rain we got that year. The hydrograph is the tool that measures

1) Properties of Phosphorus-31 system: Ideal phosphorus system has Relatively high mass difference between large and small isotope ratio (Large isotope: Small Isotope). It has high natural abundance so, we can easily measure practically. It is also related to Even Magic mass number. This type of system participates in many forms of fractionation. This system should be conservative in the process. Generally, sources are limited to others and quantity. It may be related to the signal such

(Science Daily). On one hand, there is a strong consensus that human and industries take main responsibility for the rapid increase of global surface temperatures in recent decades, and greenhouse gases such as carbon dioxide is the major cause of global warming. Meanwhile, some people that come from organizations with

has affected the global temperature negatively by forcing it to rise, and due to the higher temperature, the world's ice is melting away. The main reason that the sea level is rising is the warming and melting of many large glaciers in Antarctica, Greenland and the North Pole. In brief, climate change has caused many changes in the Earth particularly during the Anthropocene. The past one hundred years have seen an unprecedented increase in the average global temperature. According to the studies

in global surface temperatures in recent decades (Sciences, 2013). Apart from a few bodies that hold non-committal positions, no scientific body of national or international status disagrees with this view (DiMento & Doughman, 2007). When investigating climates antecedent to human history, indirect methods are exclusively depended upon. Those used to calculate past temperatures, observe responses to past temperature change that are preserved in ice, rock and fossils (temperature proxies). Marine

planet whether we choose to believe it or not. Most of the scientific community claims that global warming is to blame for the changes in Earth’s climate. However, there are a small number of scientists who deny the very existence of global warming. Temperatures on earth have increased approximately 1.4°F since the early 20th century. Over time, atmospheric levels of greenhouse gases such as carbon dioxide (CO2) and methane (CH4) have notably increased. Both sides in the debate surrounding global climate

The ancient Maya civilisation has generated great interest in many academic scholars and scientists, due to the phenomenon which saw one of the most dramatic civilisation collapses in recorded history, during what has been referred to as the Terminal Classic Period- A.D. ∼700 to 950 (Haug et al, 2003). Interestingly, the ancient civilisation has been characterised by its collapse in the 9th century, perhaps even more so than its remarkable accomplishments, such as: creating vast hierarchical and
