Climate change is defined as the change in global or regional climate patterns, which is apparent from the mid to late 20th century onwards. When looking at climate change there is an abundance of evidence that supports that humans are the leading causes of the drastic shift in the weather pattern but there is also a lot of evidence against humans actually causing climate changes. For example, the increasing levels of man made gases that are let into the atmosphere may have created a greenhouse effect, which traps heat and ultimately causes global warming. But there are also many scientists who believe that the earth has always naturally cooled down or warmed up at its own pace.

The increasing global temperatures have caused many problems in Arctic ecosystems. The increasing warmth has caused ice caps to melt, and permafrost to thaw, causing shifts in the ecosystems around them. 1According to Harris (2005) “Permafrost is soil, rock or sediment that is frozen for more than two consecutive years. In areas not overlain by ice, it exists beneath a layer of soil, rock or sediment, which freezes and thaws annually and is called the "active layer".” (p. 17). While the melting of ice may not seem like a big issue at first glance, its effects are truly catastrophic. Many professionals in this field, such as Houghton (2009) have said 2“Warming is expected to be strongest in the Arctic, with the continuing retreat of

Climatic fluctuations led to major changes in the Arctic geography, effectively increasing the diversification of high-latitude organisms, including the lagomorphs that lived in those latitudes, in the Pleistocene. The organisms expanded into the new available habitats while the glaciers receded. One of these refugiums, Beringia, in Arctic North America during the glacial maxima, has been subjected to extensive research while many other refugiums have been hypothesized such as a High Canadian Arctic refugiums (Waltari et al. 2005). Furthermore, during the last glacial maximum some coastlines in the High Canadian Arctic were ice free (Waltari et al. 2005). Eurasia was less glaciated than North America during the glacial maxima, yet a large sheet

a long-term change in the earth's climate, especially a change due to an increase in the average atmospheric temperature. “http://www.dictionary.com/browse/climate-change”

It has been observed through various researches that in the last century, average temperatures across the globe increased by over 1.3°F with an increase of more than two times in the Arctic. (Bates, Kundzewicz, Wu, & Palutikof, June 2008). The results of climate change can also be seen in changing precipitation patterns, increases in ocean temperatures, changes in the sea level, and acidity and melting of glaciers and sea ice (USEPA, 2014).

Altogether, the author effectively shows the damages that climate change causes on the Arctic Ocean. This includes changes in the water’s components, the loss of marine life, and rising oceans. The author is also able to show how imminent these problems are today, and that this is not just a topic for the future. This topic is important because the world’s emissions of greenhouse gases is hurting the ice caps exponentially, which will cause a ripple effect of harmful

Determine the mechanisms that relate the present and anticipated future variability in glacial dynamics to shifts in coastal ecosystem structure and function using laboratory and field experimentation, observations, and modeling.

The UNFCC also defines climate change as “a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over time periods.”

Spectacularly diverse and unique, the Arctic is home to a population of approximately four million people and 21,000 different species! Climate change is by far the greatest threat on the spectacularly unique biodiversity that the Arctic has to offer according to the Arctic Biodiversity Assessment (ABA) with research done by over 200 scientists from 15 countries. The Arctic in particular is expected to be negatively affected by global warming. The globally agreed upon, sustainable increase in temperature is by 2 °C. The Arctic is expected to become significantly warmer with a predicted 2.8-7.8°C rise in temperature within this next century. Extreme changes such as this are likely to have devastating effects on Arctic biodiversity due to the

Scientists define the Arctic in three major ways – first, as the area N of the Arctic Circle (lat 66030' N); second, as the region N of the 10 oC (50 oF) summer isotherm – on a map, a line drawn through locations with an average annual temperature for the warmest summer month of 10 oC (50 oF); and third, as the region N of the tree line – on a map, a line connecting points beyond which trees do not grow. The second and third definitions enclose roughly the same territory, which is somewhat larger than the region bounded by the Arctic Circle.

Climate Change is the significant change in the climate and distribution of weather patterns on Earth ranging from the last decade to millennia earlier.

The Arctic is global warming’s canary in the coal mine. It is a highly sensitive area which is profoundly affected by the changing climate. The average temperature in the Arctic is rising twice as fast as elsewhere in the world (nrdc.org). Because of this, the ice cap is getting thinner, melting away, and rupturing. Here is an example of this; the largest ice block in the Arctic, the Ward Hunt Ice Shelf, had been around for 3000 years before it started cracking in 2000 (nrdc.org) By 2002, the Ward Hunt has cracked completely through and had started breaking into smaller pieces. The melting ice caps are affecting the earth and its inhabitants in many ways. In this paper, the following concepts and subjects will be

Climate change is one of the biggest problems the whole world is collectively facing. Even though climate change is partially caused by the natural cycles of Earth, humans I think are still a major part of it and I think that we can do more to protect the environment that we live in. Climate change happens when temperatures increase dramatically. When climate change causes temperature rises many environmental problems can occur here on earth . Temperatures rising can result in more floods, droughts, or flooding rain, as well as more frequent and severe heat waves which can cause wildfires. Oceans and the Antarctic Ice Glaciers have also experienced changes in oceans that are rising temperatures and are becoming more acidic. The Antarctic ice glaciers are melting and sea levels are rising destroying many habitats along the ice glaciers such as penguins and polar bears. As these changes frequently occur in future decades, they will likely present challenges to our society and environment.

Climate change could be described as any process that causes adjustment to climate system be it a volcanic eruption to a change in the solar activity. Today, however, the phrase is most often used as climate change caused by humans. Climate change is also used commonly with another phrase – "global warming" – reflecting scientific observations of strong warming trends over the past century or so. Indicators like rising sea levels, retreating snow cover and glaciers, longer growing seasons and shifting wildlife has alarmed scientific community unanimously agreeing that the earth has warmed in the last century. Experts however are of the opinion that climate change is a more accurate phrase than global warming as the latter is just one component affecting the larger climate systems of the earth.
