Siberian Tundra Research Paper

The Arctic Sea Ice is melting or slowly disappearing and it is said to be one of the reasons of global warming. What is happens is that the Arctic Ice it melts a little and gets smaller during the summer season and than during the winter season the ice gets bigger and expands over the Arctic Ocean, “a freeze-thaw cycle that in the Arctic has been dramatically altered by global warming (Global Warming Effects).” The Arctic Sea Ice in the past could grow up to 3 meters, which is around 10 feet, but now the average thick ness is becoming much less, and some scientist are afraid that in a few decades there might not be any sea ice during the summer (Global Warming Effects). Another major thing that has been discovered is that the amount of ice

Earth has experienced many episodes of dramatic climate changes with different periods in earth history. There have been periods during which the entire planet has been covered in ice and at another time it has been scorchingly hot and dry. In this regards, earth has experienced at least three major periods of long- term frigid climate and ice ages interspersed with periods of warm climate. The last glacial period which current glaciers are the result of it, occurring during the last years of Pleistocene, from approximately 110,000 to 10,000 years age (Clayton, 1997). Indeed, glaciers present sensitive indicators of climate change and global warming and by estimating and monitoring the dynamic evolution of these ice masses, several

In the northern part of the earth and the upper slopes of all mountains all over the world, a unique biome called tundra exists. Tundra is one of the coldest and harshest biomes of the world. The winters are long and cold, and the summers are short and cool. Tundra is far from the equator; therefore, Tundra soil is generally poor in nutrients. Since the biome is covered in snow throughout the year, the arctic tundra doesn’t seem like a place where plants and animals can survive. Yet, plants and animals are able to survive, thanks to their special adaptations. In fact, it isn’t the freezing temperature that they fear; it is us, human. Today, tundra faces lots of threats and problems because of human. One of the major problem is Global

The rising heat levels from burning coal, oil and petroleum (cars) is having a huge influence on the planet as a whole, but most specifically the Arctic Tundra region. The planet has warmed up 0.5 degrees since global warming was first discovered and diagnosed, and, although that number might seem very minimal now, it is actually a huge jump in comparison to normalcy. This unnatural, manmade warmth has caused Arctic Tundra ice to melt, raising the oceans and flooding people’ homes and villages. This also destroys the Arctic Tundra area, due to the fact that there will be less and less ice, and thus less and less habitat for the animals that live in the Arctic Tundra area. This leads to the slow destruction and melt of planet Earth. The Arctic Tundra region is wholly an area of freshwater, locked up by permafrost. But now it is melting, going from beauteous ice to water. And there are some people who simply don’t care, like Donald Trump. They seem to think that as long as they can make as much money as possible, then the environment doesn’t matter, which is obviously not true. Humans actually need to care now, today, not a hundred years into the future when the average temperature is 35 degrees on a normal day. This is one of the possible, albeit farfetched, implications of continuing processing plants and coal mines. The smog and heat they produce is detrimental in every single way to the Arctic Tundra region. Global warming is the second and largest danger the Arctic Tundra region

The carbon dioxide scientists measured in the Alaskan permafrost layers was twice the amount in the Earth’s atmosphere, so had caused such concerns that it could melt and the carbon dioxide

At the present rate of global warming most of the frozen portions of the Arctic may disappear by the end of this century.

In Henry Fountain’s “Alaska’s Permafrost is Thawing”, Fountain discusses how Alaska’s permafrost is slowly thawing away. Alaska is known for its vast, snowy landscape, but that soon could be all gone. This article is directed towards people who are interested in the warming of Alaska. As the Arctic is warming at an alarming rate, wildlife is slowing disappearing and sea levels are rising.

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.

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

The first argument examined on the man-made global warning side is that increasing greenhouse gases caused by human activities is causing directly observed climate changes. The first resulting climate change discussed is warming global surface temperature. There has been an increase in global surface temperature of 0.74 degrees C since the late 19th century. In the last 50 years alone the temperature has increased by 0.13 degrees C per decade. North America and Eurasia have seen the largest increase in warmth. However, some areas of the earth have actually cooled some this past century (Easterling & Karl, 2011, para6). After the mid 20th century 70% of the global land mass saw reduced diurnal temperatures. From 1979 to 2005 the maximum and minimum temperatures have shown no change; both indicate warming (Easterling & Karl, 2011, para10). Furthermore, borehole temperatures, snow cover, and glacier recession data all seem to agree with recent warming (Easterling & Karl, 2011, para11).

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).

Glaciers are one of the most fundamental phenomenon on the planet, and much of their purpose and impact on earth has been well documented and published. Ice sheets, Ice Caps and Glaciers trap nearly 90% of the world's fresh water, and are replenished by snowfall each year. Their existence on this planet dates back 650,000,000 years and yet they are always moving, always shifting and always melting. Before, human existence and even during the brief era of humans, ice dominated all of the earth's landmass and have regulated, created and altered many of the landscapes around the world.

Kolbert provides compelling evidence of Global Warming in the Arctic from her hands-on experience accompanying scientists in the field. From the storm surges that threaten the Alaskan village of Sarichef to the warming (and even melting!) permafrost, the evidence all point to the irrefutable fact that the planet is warming up extraordinarily fast. In fact, the Keeling Curve gives us a rather explicit visualization of how greenhouse gases levels (CO2, in particular) are rising at unprecedented rates.

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

One of the effects of global warming is the polar ice caps’ melting. Scientists have been researching and examining the polar ice caps for a long time and they have come to the conclusion that the thin ice sheets are slowly wasting away. They have also found out that Greenland’s glaciers are getting smaller and smaller. Places around the globe that use to be covered in ice and snow are now showing more green terrain as the years go on and as the winter months grow warmer. The polar ice caps are melting more and more due to higher global temperatures. This is really bad because the ice caps “reflect and help regulate the Earth’s temperatures.”
