Ice cores taken from the Arctic have shown that carbon dioxide levels are much higher now than the last thousands of years. The higher amount of carbon dioxide in the atmosphere means warmer temperatures. There is now stronger evidence linking the warming of the ice to human activity. Global warming is caused by the green house gases, which leads to the melting of the ice, thereby affecting the ecosystem. Therefore, there is a need for everyone to reduce the amount of carbon emissions that causes the warming effect. The melting of the ice caps is the biggest and fastest change to the Earth ever caused by human activity. Alun Anderson, author of “The Great Melt The Coming Transformation of the Arctic”, states that “Temperature rise was always expected to be fastest in the Arctic. White ice reflects sunlight back into space like a giant mirror, but when it turns into dark water, the heat is soaked up instead. The seas then warm, more ice melts, and even more heat is absorbed in a destructive feedback loop that amplifies temperatures.” The disappearance of the ice is by no means the end of the Arctic itself. Humans will not only have destroyed the Arctic but transformed it as well, making it more like the waters of the south. Humans have contributed to greenhouse gases by burning coal and oil, such as gasoline, deforestation and other gases that are released into the air. As greenhouse gases are released into the Arctic, they will carry with them the possibility of increasing
This decrease has been not only increasing the sea level at an unnatural rate, but also endangering many arctic species. As these species are forced to change their hunting habits, the native villages are starving themselves, knowing only how to hunt the animals in the pattern they moved before. While the polar ice caps melt more and more, the purity of the water is negatively affected which, in turn, directly affects the air purity, too. According to experts from the Environmental Protection Agency, greenhouse gases are emitted mostly from electricity, industry, and transportation (epa.gov/climatechange). Even though the amount of greenhouse gases have been rising very unsteadily the past 100 years, these gases have been and always will be crucial to our survival on this planet, as long as there is a steady balance between greenhouse gases and carbon dioxide. When we emit carbon dioxide into the air, the atmosphere becomes more acidic; this causes the greenhouse gases to become further amplified and more likely to break down the ozone layer, which in turn pollutes the air even further, creating an endless
Global warming is one of the most tumultuous topics in today’s society. Some believe it is happening as we speak, while others question its very existence, So, is it real, or is merely a hoax? There is no one answer, but evidence does overwhelmingly support the former. Surely we have all heard this word at one time or another, but few individuals actually know its true definition. Justifiably, however, global warming is not that simply explained. In layman’s terms, it is the dramatic increase in the Earth’s average air and ocean temperature since the 20th century. This increase is primarily attributed to two main culprits: the greenhouse effect and human activity, such as fossil fuel burning. In both cases, carbon dioxide (CO2) is the
Climate change is going to affect the arctic more dramatically than other parts of the world. A study has shown that the average temperature has risen over 2ºC from 1960-2011 ("Climate Change In the Arctic"). Just a couple weeks ago the arctic was 20ºC higher than usual. Rising temperatures are going to affect the sea ice and glaciers, vegetation and wildlife as well as infrastructure. Of course these things won't just disappear quietly, they will take many other things down with them.
The theories used to “prove” that “global warming” may be a severe problem could be proven wrong. The causes of “global warming” are a great thing for essential life. All the causes and effects of “global warming” make up the Earth that people live on today. These causes and effects create a better planet for people to live in. Without
I learned CO2 in the atmosphere is causing the ice sheets to melt and it’s been going on since the Industrial Revolution. Ice sheets are starting to melt, coastlines are flooding from rising seas, and some types of extreme weather are growing worse (What Does a Climate Deal Mean for the World?,
The sun power and warm’s are earth, as two thirds of solar-energy enter our atmosphere as visible-light, the greenhouse effect absorbs the solar-energy to keeping the earth warm and later releases one third back into outer space. Without the “natural greenhouse effect” the earth's temperature would be below 32 degrees fahrenheit (The freezing point of water). The burning of fossil fuels as an energy source releases a variety of gasses such as Methane, nitrous oxide, and CO2 adding to the greenhouse effect. Because of this heat is kept longer, warming our atmosphere and causing what we know as global warming. One of the issues with global warming, is the destruction of ice polar caps that contributes to the rise of the ocean level, and causes
At the present rate of global warming most of the frozen portions of the Arctic may disappear by the end of this century.
Here is how the people and their environment will be affected by Arctic warming. The Arctic culture and the people’s activities are already threatened by certain factors such as social, economic, and political conditions. There is now a new threat: Arctic warming. The Arctic people’s culture and activities depend on the Arctic environment which includes the cold weather, ice, and snow. In addition, there is a rise in the ultraviolet radiation that reaches the Earth. This extra ultraviolet radiation has negative effects for the animals, humans, and plants of the area. Finally, the people of the Arctic will be impacted by factors such as growing populations, urbanization, and self-determination movements.
This is also known as the greenhouse effect. The greenhouse effect has much stronger results in the arctic as small changes in temperature have very strong reactions. While average temperatures have increased, the warming at the pole has more than doubled the global average. According to NASA, arctic sea ice is now declining at a rate of 13.2% per decade.
At the GLACIER Conference, President Obama said, “climate change is no longer some far off problem; it is happening here; it is happening now”. President Barack Obama states a good fact; climate change is affecting the world tremendously. The glaciers are melting at an astonishing rate and the surface temperature of the world is only increasing. Currently, scientists argue that climate change intensified because of human activity; however, the circumstance is quite the opposite. Global warming refers to the rising surface temperature, whereas climate change includes warming and the effects - like melting glaciers, heavier rainstorms, or more frequent drought (Kennedy and Lindsey). Human produced gases play a factor in global warming but humans are not responsible for climate change because global warming only represents one aspect of climate change. Although human activity plays a part in global warming, human activity is not primarily responsible for climate change because the fluctuations of the sun’s heat is responsible for the increased surface temperature, the levels of human produced CO2 do not correlate with the increase in surface temperature and the computerized climate models display inadequate and incorrect information.
Climate change or colloquially known as global warming, now pose a new threat to civilization as the levels of greenhouse gases (GHG) are soaring to new levels. The most significant contributor to greenhouse gasses would be Carbon Dioxide (Co2). The levels of Carbon Dioxide (Co2) gas have risen to levels civilization has not seen before. As such, the effects of these levels are not known to civilization as data gathered from the ice cores drilled in the Antarctica only shows data up to 650,000 years ago. However we can conclude that present CO2 concentrations are higher compared to any time in the last 650,000 years (IPCC 2007). Current carbon dioxide concentrations are hovering around 389 parts per million (ppm) as of September 2011,
Another natural cause that could have an impact on global warming is the melting of permafrost in the arctic. Permafrost is any rock or solid material that has been frozen for 2 or more years. Permafrost lies mostly in sub-arctic and arctic conditions. The ways ecosystems have changed, these regions have turned from storing carbon dioxide to being a main source and releasing it. As these solid materials continue to be frozen, more atmospheric gases and methane continue to be trapped. When the temperature of the air and the ground rises, the permafrost melts and releases the gas into the air. The thawing of this ground releases carbon and methane, which has a major impact on the climate change in that region. Methane is about twenty times
The world warmed by about 0.7°C in the 20th century. Every year in this century has been warmer than all but one in the last century (1998). If carbon-dioxide levels were magically to stabilize where they are now (almost 390 parts per million, 40% more than before the industrial revolution) the world would probably warm by a further half a degree or so as the ocean, which is slow to change its temperature, caught up. But CO2 levels continue to rise. All this affect the ice pack in the Arctic. As temperature rises, ice melts. This causes many problems.
What causes the melting of glaciers is global warming and the heat which is continuing to rise. Global warming is causing the heat to rise over these years, because we are burning more fossil fuels and greenhouse gases, which invent more heat that gets trapped in the atmosphere of earth. The three sources that contributes to the problem I’m investigating are: The Consequences of Global Warming on Glaciers and and Sea Levels, Global Warming puts the arctic in thin ice, and lastly Global Warming is causing rain to melt the Greenland ice sheet.
