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
For years to come there will always be a speculation on whether the climate change has really taken place or not. Many believe that large companies launched this topic in order to benefit from it in profit, as there are also those who are convinced that this are consequences that have emerged from human mistakes in understanding the environment. As humans are struggling to trust one another whether it is just a big conspiracy or not or environment changing itself, we are slowly starting to feel the effects of climate change. Because of the gasses (CO2) that are in the air, atmosphere is getting warmer, thereby triggering the Greenhouse effect. Almost 70% of emitted gasses in air are CO2, which leads us to believe that this is the main cause of Global Warming. Since it is billions and billions of metric tons per year that are being released in air, many scientists conclude that temperature will most likely be more higher in twenty years from now, than it was in near past.
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.
Although, both the Aphrodite of Knidos and the Birth of Venus have like traits such as nude female body, contrapposto stance, and iconography, they also can be easily contrasted by period of creation, technique, and artist. The human body has always been a popular choice among artists, but it seems the nude female body is quite controversial. The Aphrodite of Knidos, sculpted by Praxiteles about 350 – 340 B.C., or during the Greek Late Classical period, was a nude female modestly covering her genitalia. The Aphrodite was what made the small island of Knidos known to people around the world. Some 1,000 years later, the Birth of Venus arrived. Artist Sandro Botticelli, during the Italian Renaissance (ca. 1482,) defied odds with a similar interpretation of the Aphrodite despite stricter views on nude women. Both pieces share similar traits, yet can be easily identifiable apart from each other.
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 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.
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...

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
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 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.
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)
