Greenland Ice Sheet Summary

The temperature of the earth is controlled by the cold waters of Antarctica and the warm waters of the tropics. The rising of Antarctica's water cools not only other seawater, but also the air. Now, humans have begun to disrupt this natural occurrence through global warming and pollution. ( Audubon 17)

Ice cores are to ice sheets as tree rings are to trees. Just as the rings on trees provide information about trees ice cores do the same for ice sheets. Jack was taking ice core samples from Antarctica because the samples allow scientists to study the chemistry and composition of the climate from past times. Ice cores have been used to study glacial and interglacial periods. The ice and snow acts as a natural preservative for debris and chemicals. Climatologists analyze concentrations of greenhouse gasses in layers in ice cores to determine the past climates. Scientists can calculate how today amounts of carbon dioxide and methane compares to those of the past.

Oceans benefit the population in many ways, one of them being income. Many jobs stem from

About 71 percent of our planet Earth is covered by water, and the majority comes from the oceans (about 96.5 percent of all Earth’s water). It remains as the most expansive, diverse, and mysterious places on planet Earth. But it is being threatened by the pollution by people and nature itself. By polluting the habitat of marine organism will indirectly affect the ecosystem of the marine life. Marine life is dying and as the result the oceanic ecosystem is threatened.

Over time our planet has become increasingly more industrialized. More factories have been built and increased air pollution has been found all over the world. The surface temperature of the ocean has been steadily increasing as well since the 1950’s (Source B). This has led to people to believe that the surface temperature of the ocean correlates with air pollution. If air pollution increases, so will the temperature of the

Global warming is a big problem that we have to face nowadays. If you search Google for the word “global warming’, you will get over 70 million pages of results.

Earth’s climate has been changing over the last few decades, with the global temperatures rising at a high rate (Corell, 2006). Some of these climate changes are due to natural causes, although the strength at which temperatures are rising indicates human influences, such as increased carbon dioxide emission, as well as other greenhouse gases. Climate change particularly affects the Arctic region, where warmer temperatures are causing decrease in sea ice extent and thickness, permafrost thawing, coastal erosion, changes in ice sheets and shelves, and consequently, changes in the distribution and reproduction rates of Arctic species (Corell, 2006).

This quote said by Washington State Governor, Jay Inslee shows the severity of climate change “We are the first generation to feel the sting of climate change, and we are the last generation that can do something about it.” “On Earth human activities are changing the natural greenhouse of the Earth.” (A blanket around the Earth). Burning fossil fuels is causing carbon dioxide to be released into the air. By releasing this gas into the air the natural greenhouse gases increase and cause many effects to happen. Carbon dioxide is also caused by removing natural resources from the land for agriculture.

The article, “Melting Glaciers blamed for subtle slowing of Earth’s Rotation,” by Will Dunham, talks about how the melting of glaciers appears to be slightly slowing down the Earth 's rotation. Also about how the melting of glaciers are due to the world 's temperatures. At the beginning of the article William Dunham states that the driving force behind the discernible change in the Earth 's rotation is measured by satellites and astronomical methods. Also that the global sea level rise is fuelled by an influx of meltwater into the oceans from glaciers. A geophysicist, Jerry Mitrovica, explained more on this problem when he said, “Because glaciers are at high latitudes, when they melt they redistribute water from these high latitudes towards

There are other ways also that affects the ocean through global warming. Plenty of things that are happening to the ocean are associated to global warming. One important thing is warm water which is caused from global warming and it is harming and killing algae in the

They are investigating into natural cycles and patterns and trying to figure out its results in measurable terms. However, this measurement is not precise enough to be reliable until other interconnecting factors like greenhouse gases are taken into consideration.

Arctic ice reflects 80 percent of the sunlight back into space. As sea ice melts there will be more sunlight hit the ocean which increase the temperature of the ocean and cause raise of sea level. Satellite observations show that Arctic sea ice concentrations have significantly decreased over the last 25 years. Submarine observations also suggest that the Arctic ice pack has thinned dramatically in the last 20 to 30 years. As the sea ice melts the sea level increase. Sea level is now rising by 3.1mm per year. At this pace, more than 2.5 m sea level rise by 2040.

It is common knowledge that sea ice has been melting rapidly within the last decade. This rapid decrease in sea ice has many detrimental effects. This includes the rise in sea level, loss of arctic environments for animals, and the change in weather patterns. Ice is lighter in color so it reflects much of the sunlight that is put out. When open water is revealed from ice melt it is darker in color so it absorbs more sunlight, leading to that rapid melting of ice that we see today. This loss in sea ice can only help one industry, which is shipping. When the sea ice melts, it opens up new shipping routes. The “Northwest Passage” is an arctic sea route which connects the Atlantic and Pacific Oceans. This route is shorter than the traditional

What is global warming? Global warming is defined as “ an increase in the earth 's average atmospheric temperature that causes corresponding changes in climate, and that may result from the greenhouse effect" (“Global warming”). Natural events and human that causes global warming are believed to be factors to increase in average temperatures. This essay looks into the growing problem of global warming and suggests reasonable solutions to it. It also evaluates the effectiveness of these solutions.

The effects of the climate change are undeniable in the scientific research. The Intergovernmental Panel on Climate Change and other meteorological organizations measures the temperature of the earth on the daily basis and has indicated the potential increase. Furthermore, the dramatic decline in ice and glaciers in the North and South Pole verify the rising temperature and its impact on the sea level. It should be noted that from last decade, the sea level has been increased due to melting of the ice that ocean currently pose a threat (Shrestha, Babel, & Pandey,
