Permafrost

Causes of Global Warming Global warming is the increase in the earth’s average temperature due to release of several greenhouse gases to the atmosphere by humans. Global warming is affecting many parts of the world. Due to global warming, the glaciers are melting which is causing the rise in the sea level. When the level of the sea rises, it causes danger to the people living in the low lying areas. When the level of the sea rises, it covers the plants and causes some of them to die. When they…

The global consequences of increased levels in carbon monoxide and methane due to the melting permafrost cause warming in polar regions and unpredictable behavior of the northern jet stream. According to the U.S. Global Change Research Program, the changes in climate cause adverse side effects; such as summers becomes longer and hotter, winters becomes…

Anthrax is thought to be an ancient illness. While there is no way to be completely sure, as it was not referred to as anthrax at the time, many scholars date anthrax all the way back to 700 BC during the periods of ancient Egypt and Mesopotamia (CDC, 2016). According to the CDC, “Many scholars think that in Moses’ time, during the 10 plagues of Egypt, anthrax may have caused what was known as the fifth plague, described as a sickness affecting horses, cattle, sheep, camels and oxen” (CDC, 2016)…

It is cold in the winter and warm in the summer. To most Americans global warming does not seem like a problem. If it is hot out we simply turn our thermostats to a colder temperature and if it’s cold we crank up the heat. However, CO2 levels are rising to levels never before seen by humans and its happening at a rate faster than ever. Through scientific modeling it is clear that temperatures never before seen by humans are going to be endured faster than anticipated and without combating the…

is also a windy place and winds can blow between 30 to 60 miles per hour. The tundra is basically like a desert when it comes to precipitation. Only about 6 - 10 inches of precipitation (mostly snow) fall each year. Below the soil is the tundra's permafrost, a permanently frozen layer of earth. Some Arctic tundra animals include musk oxen, wolves, ptarmigan, snow geese, tundra swans, Dall sheep, brown bears (and polar bears near the coast). A number of small rodents and rodent-like animals are…

Over the past fifty years the earth has gone through numerous climate changes. Such changes include permafrost melting, receding glaciers and the disappearance of sea ice. Due to these changes the earths landscaped has changed. In the sea ice animation from Cryosphere Today, we can see how the sea ice has changed dramatically growing in the winter months and then dissipating during the summer months. Most of these changes occur not only from the climate change itself but rather from human…

It is on the local news or found in the newspaper. It is in the air that people breathe every single day. However, many humans are still not aware of the harmful effects of global warming. Carbon is emitted into the air daily because of the burning of fossil fuels. Eventually, we will run out of fossil fuels. Then what happens? There are plenty of clean alternatives that put little to no greenhouse gas into the atmosphere. One small switch at a time could save a population of polar bears or even…

4a. The Canadian Arctic: Geography, ecology, people and climate The Arctic is often defined using political, climatic, biological zoning and varies greatly amongst Arctic nations. Using geophysical definition as the land and sea, north of the Arctic Circle and which experiences polar day from April to September, and polar night from October to February. Overall, Arctic climate varies greatly by location with annual mean surface temperatures of 4C in Reykjavic Iceland, to -28 C at the crest of…

The area the Himalayas are geographically located within hold the greatest amount of ice outside of the polar region, and within the region, contains the ten largest rivers in Asia, (Wilkes & Eriksson, The Melting Himalayas: Cascading Effects of Climate Change on Water, Biodiversity, and Livelihoods, 2009). Although the Himalayas contain a great source of ice due to high alpine glaciers, climate change is rapidly changing the topography of this area by accelerating the melting of ice, (Wilkes,…

Have you ever wondered what animals live in the Arctic Tundra? Well a lot of animals live there and there’s a lot of places where the Arctic Tundra is located, but I’m talking about the amazing polar bear. There’s nothing that can even compare to them, that goes for the Arctic Tundra as well. The Arctic Tundra is found in a variety of locations; across Northern Alaska, Canada, and in Siberia. I’m talking about the Alaskan tundra though. The Arctic Tundra has a very unique climate, long cold…
