In a recent political conversation with my stepfather, Keith, the topic of climate change came up. Keith told me that in 2002, NASA came out and said there was frozen ice on Mars, and now 14 years later, they have found that there is flowing water on Mars. Keith’s comment on this was, “Of course there is flowing water! The ice has melted. Mars goes through periods of temperature change just like the Earth does.” After researching on my own, I have found that many planets have these types of changes occur, namely Venus. Venus used to have oceans long ago, but now the surface is completely dried up and scorching hot. You would think this is due to the fact that Venus is thirty percent closer to the Sun than Earth is, but that is not the reason at all. …show more content…
This “greenhouse effect” on Venus happened completely naturally, however the greenhouse effect that we see happening on Earth is ultimately man made. Yes, Co2 is found on Earth at natural levels due to volcanic eruptions and it is what living things exhale, however there is a difference between natural Co2 and burned fossil fuels, the Co2 emitted from volcanic activity is slightly heavier and only makes up two percent of the thirty billion tons made by human activity each year (Tyson). While Co2 is naturally occurring on the Earth, our burning of fossil fuels are causing the Co2 levels to spike, which can have a terrible and irreversible outcome if we do not fix it soon. The climate change that the Earth is experiencing is undeniable, it is important to understand the factors that affect climate change, the repercussions if it is ignored, and how we can prevent it from happening at
The Intergovernmental Panel on Climate Control (IPCC) was established in 1988, reported in 2007 in “very high confidence” that since 1750 human activity has played a major part in overloading the atmosphere with carbon dioxide. Whether it’s through cellular respiration or the burning of fossil fuels is debatable. Cellular respiration is a process of creating energy and it takes place in all living things, even in plants. Carbon dioxide, oxygen, light and water are important factors in this process. Keeping a balance level of carbon dioxide is crucial to the earth’s atmosphere, because if it gets too high, it increases the average temperature on earth, which is unfortunately what we are dealing with and call “global warming”. I believe cellular respiration does not affect global warming as greatly as industrial fossil fuels do.
1.) Discuss the meaning of the Paleolithic Venuses. Identify Rice's position and explain it. Discuss four other interpretations of these figurines mentioned in class or in the reading. Do any or all of these interpretations support the views of the 19th century evolutionist Johann Jakob Bachofen?
The levels of carbon dioxide in the atmosphere were 15 times higher than they are today and this was due to the volcanic activity, which released enormous amount of carbon dioxide gas into the atmosphere. The flooding of continents and the lack of plants on land also contributed to the heightened levels. These conditions created a greenhouse effect so tempera...
The Birth of Venus, by Sandro Botticelli, after 1482, was the choice for my writing assignment. It can be found on page 401, in our textbook, The Humanistic Tradition, by Gloria K. Fiero. The painting is a tempera on canvas and is 5ft x 9ft ½ in. Canvas was often used because it was less expensive and easier to transport. The Birth of Venus was one of the first non-biblical female nude paintings. Many of the earlier artwork of nude females were of Eve. As I was doing research, I found many different opinions and interpretations of the work. Often nude female artwork enhances a demeaning image of the female.
Venus, the second planet closest to the Sun and Earth’s closest neighbor, is known for its many wonders and harsh conditions. Venus is possibly the first planet discovered by humans and is said to have been first discovered in 17 B.C. by Babylonian astronomers. Venus is the first planet to be explored by spacecraft although many of these attempts have proven unsuccessful. Fortunately, more than twenty of the spacecraft explorations been proven successful, and through those we have gained knowledge about this wonder of the night sky.
The Birth of Venus is a beautiful Renaissance canvas masterpiece created by Sandro Botticello. The picture illustrates the birth of Venus in a very mystical way. Venus has emerged from sea on a shell which is being driven to shore by flying wind-gods. She is surrounded by beautiful roses which are painted in a truly remarkable color. As she is about to step to land, one of the Hours hands her a purple cloak. The back drop includes the sea and a forest. The overall effect of this painting are almost overwhelming, color and beauty meet the eye in every angle.

Humans are polluting our atmosphere causing the Greenhouse Effect. What’s the Greenhouse Effect? “The Greenhouse Effect can be visualized as follows: imagine that Earth has been encircled by a giant glass sphere. The heat of the sun penetrates through the glass. Some of the heat is absorbed by the Earth, and some is radiated back towards space. The radiated heat reaches the glass sphere and is prevented from dispersing any further”(Global Warming The Facts). This makes the heat bounce back towards the Earth, which heats it up tremendously.
Climate change is a long-term change in regional or global climate patterns. From the mid twentieth century to now, it has mostly been about a significant increase in average global temperatures. Climate change is a major issue in the world today, and a lot of people feel very differently about the cause of it. The common argument about it is whether climate change is a natural occurrence or if the recent increase in temperatures is because of humans. Climate change is a natural cycle in the Earth’s weather. Before humans started burning fossil fuels, there were still weather cycles on Earth that were as hot or hotter than what it is now. In fact, Earth’s weather now, is on pace with the previous weather patterns in history. Human emitted
The commonly debated “greenhouse effect” refers to “the global average temperature increase that has been observed over the last one hundred years or more” (Spencer). President Barack Obama addressed the issue in an effort to highlight its severity, "We have to all shoulder the responsibility for keeping the planet habitable, or we’re going to suffer the consequences – together” (Leader). The earth’s increasing atmospheric and oceanic temperatures result in climate changes due to cumulative amounts of carbon dioxide (CO2) in the atmosphere. As an outcome, researchers around the globe have established that the by-product of burning fossil fuels is the main culprit of the increasing temperatures. Global carbon emissions from fossil fuels have significantly increased since 1900, as shown above from a study carried out by the Carbon Dioxide Information Analysis Center.
Climate change is evidenced through shifts in the weather patterns such as winds, humidity and temperatures over certain durations. Natural climate changes occur less frequently and they are triggered by factors related to geographical aspects as well as solar radiation. The earth’s movement on the orbit triggers changes in climate, causing some areas to have higher temperatures than usual, while others are significantly cold depending on the position of the earth on the orbit. The heat from the sun causes changes in the stratospheric ozone and it increases the amount of greenhouse gases. Heat from the oceanic crust also contributes to warming as a result of episodic hydrothermal venting (Liao & Sandeberg, 2012).
Planet Venus The planet Venus is able to reach a max temperature of 870 degrees Fahrenheit. Venus is mainly known for its heat, as well as its unusual atmosphere. Venus’ atmosphere is denser than any other planet, even though it is commonly compared to the planet Earth because of its many shared characteristics. These characteristics include size, mass, density, composition, and gravity.
As defined by the Oxford dictionary, climate change is, “a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.” (Oxford Dictionaries) Moreover, evidence of climate change can be found all over the world, and in many different forms, but is especially prevalent in certain regions. For instance, in Southeast Asia, specifically the nation of the Philippines, signs of climate change can be observed frequently, if not regularly. One major ...
This is based upon the sunlight and volcano eruptions which plays an extreme factor. "Most often, global climate has changed because of variations from sunlight. Tiny wobbles in Earth’s orbit altered when and where sunlight falls on Earth’s surface. Variations in the Sun itself have alternately increased and decreased the amount of solar energy reaching Earth. Volcanic eruptions have generated particles that reflect sunlight, brightening the planet and cooling the climate. Volcanic activity has also, in the deep past, increased greenhouse gases over millions of years, contributing to episodes of global warming." (Global Warming, web.) However, I firmly believe that climate change is not only the result of natural causes alone. I think it is man-made and the major factors are from CO2, factories, and power plants burning coal/ oil, natural gas.
Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. The greenhouse gases are carbon dioxide, methane, and nitrous oxide. “Carbon dioxide is released into the atmosphere when solid waste, fossil fuels, and wood are burned.” (2) The gases help to warm the surface of the Earth. Each greenhouse gas absorbs heat differently. If natural gases did not occur, the temperature of the earth would be considerably cooler. “Problems can occur when higher concentrations of greenhouse gases are present in our atmosphere because they have enhanced our earth's heat trapping capability.” (3)
