One of the more pressing issues over the course of the past century has been that of climate change. We have been quite aware of the effects climate change has had throughout our environment, however, one place in particular where it has been affected the most has been in the Arctic. In 2012, it had been noted that the melting of the polar ice sheets was responsible for a rise of approximately 11mm to global sea levels in the two decades prior (Shukman, 2012). Unfortunately, this is not where it ended. The continued melting of the ice caps across time has led to a significant increase in global sea levels which continues to have an impact on our environment.
Our atmosphere stores gases, known as greenhouse gases, like water vapor, carbon dioxide, methane gas, fluorinated gases, and nitrous oxide. These greenhouse gases trap some of the radiation which warms our planet to allow humans, plants and animals to survive. The dramatic changes to the climate from greenhouse gases is not a natural process which is why the climate changes are such a big issue . Throughout the history of the earth natural climate changes have been known to occur over thousands of years due to the Earth’s orbit and the exposure to the sun. That fact is actually used in arguments for people that believe global warming is a myth.
Biomes and Climate Change by vburnin The biome I researched is the arctic tundra 1. Climate change has had several impacts on the abiotic factors of the arctic tundra. One of these factors is the length of the seasons, winters begin late and springs come earlier. It has been observed that changing world temperatures effect colder places the most. Rising temperatures in the arctic tundra have led more permafrost and snow to melt than usual causing the tundra to be converted to wetlands.
Climate Change Regulation Gina Woods SCI/362 October 17, 2011 Climate Change Regulation The planet historically has gone through a few climate changes. Scientist, who study the climate know the earth climate has already been in a cooling stage, which is the Ice Age, and is in a warming stage in which is called Global warming. Some scientist study show that the earth climate change is moving into another cooling stage in the next decade. “The climate change is Global warming, the increase temperature of the atmosphere near the earth surface” (“American Meteorological Society 2007”). In earlier decades, the natural effects to the climate change, such as volcanic eruptions with the Industrial Revolution, human began to put their
First of all I will explain various viewpoints on climate change. The various viewpoints come from different parts of the world like the United States, China, Russia, and India. The viewpoint from the United States is one of the defining challenges of their time talking about how the science is clear and conclusive and the impacts no longer can be ignored. Here is a quote from President Barack Obama on July 9 at the G8 Summit on the Major Economies Forum on Energy and Climate, L'Aquila” Ice sheets are melting. Sea levels are rising.
Lipoczi 2 First of all, scientists blamed the climate change as one of the most potential reasons by that the mammoth could fade away. According to a journal, “Near the end of the ice age, as the ocean surface temperature cooled at mid and high latitude, and evaporation slowed, the equable ice age climate would have changed to a drier, more continental climate with more seasonal extremes” (Oard). It was
NOORDIYANA F MOHAMAD REACTION ESSAY Hurricane Sandy due to Global Warming In the article “Sandy: Act of God or Act of Man?” (Los Angeles Times, November 1st 2012) by editor of LA times claims that Global Warming may have caused Hurricane Sandy. There are debates and argues about the relationship of Global Warming and Hurricane Sandy. “Pundits and politicians were arguing about that even before the massive storm struck the Atlantic coast; now that it has moved on, after killing 50, flooding the New York subway system, ripping away chunks of New Jersey's coastline and causing myriad other damage that will place Sandy among the most expensive natural disasters in U.S. history, it's a more pressing question.” (para. 1). The arguments involved myriad of people claiming whether or not Global Warming has anything to do with Hurricane Sandy.
Ice in Motion In the article Ice in Motion by Alexandra Witze, the author essentially examines "ice dynamics", the movement and melting of glaciers, and the consequences of these changes to our environment currently and in centuries to come. Greenland and Antarctica are home to some of the world's largest glacial masses; this article also provides details of multiple studies conducted in those regions. To provide some perspective: Greenland loses as much ice in a year as is in the entire Alps. Antarctica's Pine Island Glacier is a major contributor to rising sea levels and recently produced an iceberg of 720 square kilometers - approximately eight times the size of the island of Manhattan. (Witze, 2011).
The Day After 2012 In a chaotic situation where from one day to another everything around is destroying in pieces, the two choices are to accept the time has come or do what is possible to remain alive. The Day After Tomorrow and 2012 are two films that experience a terrible Global warming disaster, and face a situation where they have to escape to survive. The Global Warming is accelerating and affecting not only the weather, but the Earth too. In The Day After Tomorrow a massive ice shelf breaks off Antarctica, and follow by an Ice Age heading their way. Unlike in 2012, the Earth’s core temperature starts to rise, and begins to warn that the crust will become unstable very soon.
Scientists have correctly been showing that if we had no greenhouse effect the earth’s average temperature would be much colder and consequently human life would be impossible. In order to understand how people are able to influence these processes, a further illustration of the greenhouse effect can be useful. After reaching the earth surface the solar radiation is converted into heat and reflected to the universe. Because of the greenhouse gases which are able to absorb and to reflect a huge part of the thermal radiation back to earth, the global average temperature increases from -18 C up to 15 C. However the huge problem is that the human race is devastatingly intensifying this effect. During the past years people all over the world have experienced changes in precipitation and increases in temperature.
