Carbon Dioxide Emissions Essay

In September the sea ice reaches its minimum amount. Every September the arctic sea ice declines at a rate of 13.4 percent per decade.The glaciers have estimated to have been losing mass since the 1970s. Antarctica has been losing about 134 billion metric tons of ice per year since 2002. In 2007 the arctic ice decreased dramatically, but around 2013 the sea ice started to recover.

B) In 2007 there was a massive polar ice melt and the amount of glaciers and sea ice has decreased quite a bit since the 70's. This has already caused the sea levels to rise.

1. Sources are cited in the body of the paper using APA format (up to 5 points)

e. explain how the research found in the database relates to your topic of interest. This may be an additional paragraph, perhaps two or three sentences.

· Read the abstract and introduction at the beginning and the conclusion at the end of the article first. The topic and hypothesis will be provided in these sections. Then read the methodology and data/results sections. Reading the introduction, summary, and abstract will help you better understand and follow the data-heavy results section.

Stunted Again” written by Michael Pearson, the Earth is in trouble due to the decrease in Arctic

Climate change will cause the air in the arctic to get warmer which melts the permafrost in the ground. The Sea ice will melt due to higher temperatures of the air and ocean, ending in rising sea levels and the melting of glaciers. You might think we have lots of time before this happens but in reality each year we lose about twice the size

The rate of retreat and the rate of thinning in all seasons considerably surpassed the forecasts of most models (Wadhams, 2012). According to Barber et al. (2009) investigation of thermodynamic oceanic contributions to sea-ice thickness specifies that longer summer melt season, a decrease in multi-year and ridged ice, and warmer Atlantic water account for continued thinning of the Arctic Ocean sea ice. “Sea ice in the Arctic Ocean has been in retreat, the annual-averaged rate speeded up to 10.7% per decade from 1996 onwards” (Wadhams, 2012). According to Bring and Georgia 2013, new model predictions, the summer sea ice disappearance within 20–30 years. At the same time, submarine sonar measurements have revealed that the ice has been thinning much more rapidly. (Wadhams,

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.

Additionally, temperature and CO2 levels maintain an average baseline that both temperature and CO2 levels will ultimately return to, creating a balance between the two. However, when temperature increases too dramatically, a tipping point is reached and glacier sizes will drop without returning back to its original size. The excess of CO2 emissions released into the atmosphere mainly caused by human activities has tilted the balance to one extreme. This phenomenon is the beginning of a chain event, which ultimately leads to the melting of our polar ice caps and glaciers. Due to the melting of ice, the average sea level is expected to rise a minimum of one and a half to three feet during our generation, which would force approximately 150 million individuals to move to a new

One of the global warming changes our planet is going through is the melting of glaciers in the Arctic sea. John Hawkins states, “How much Arctic ice really matters is an open question since the very limited evidence we have suggests that a few

2) State the hypothesis tested – Did the authors state one or is it implied? If there is more than one hypothesis then state those as well.

List your References for your citations above (Cite your sources for information and data provided, just as you would in any written assignment).

Ice is one of the first indicators of global warming actually occuring and it is important for research to be done on these layers of before they disappear. The recession of glaciers and the fragmentation of ice caps has been a clear sign to many that rising temperatures are having an impact, even on our very lives.
