Ice in Motion In the article Ice in Motion by Alexandra Witze, the author essentially examines "ice dynamics", the movement and melting of glaciers, and the consequences of these changes to our environment currently and in centuries to come. Greenland and Antarctica are home to some of the world's largest glacial masses; this article also provides details of multiple studies conducted in those regions. To provide some perspective: Greenland loses as much ice in a year as is in the entire Alps. Antarctica's Pine Island Glacier is a major contributor to rising sea levels and recently produced an iceberg of 720 square kilometers - approximately eight times the size of the island of Manhattan. (Witze, 2011).
The area can be defined as north of the Arctic Circle, or the region where the average temperature for the warmest month is below 10°C. 2. How is the climate changing in the arctic? In the past few decades, average Arctic temperatures have risen twice the rate of the rest of the world, approximately 3-4oC in the last 50 years in Alaska. Over the next 100 years they could rise a further 3-5 oC over land and up to 7 oC over the oceans.
Iceland is warmed by the Gulf Stream. The Laki eruption wasn’t really a single event, but rather 8 months’ worth of lava flows and explosions that ejected an astounding 14.7 km cubed of ballistic lava that came out of 140 vents. The eruption was caused by small earthquakes that were hardly detected by the seismometers the eruption caused a gigantic amount of smog and poisonous gasses to envelope Iceland in a matter of days which caused at least 10,000-15,000 deaths in Iceland alone. Consequences in Iceland Affects of a volcanic eruption An estimated 20–25% of the population died in the famine and fluoride poisoning after the fissure eruptions ceased. Around 80% of sheep, 50% of cattle and 50% of horses died because of
The winter temperature range is -54 to -1° C (-65 to 30° F). The winters, as you can see, are really cold, with lots of snow. Temperature range in the summer gets as low as -7° C (20° F). The high in summer can be 21° C (70° F). The summers are mostly warm, rainy and humid.
Throughout the course of history, few events have had an enormous cultural impact on worldly civilization as the “Little Ice Age”. The term Little Ice Age describes a period of about 500 years spanning from the 14th century to the 19th century (cite movie). It was a period of time where average global temperatures were 2-3 degrees Fahrenheit cooler than normal (Gardiner, 2005). This worldwide cooling trend had a significant impact on war and political outcomes, agriculture, and human adaptation. The film entitled “The Little Ice Age” by National Geographic demonstrated these impacts with historical documentation and, more importantly, scientific discoveries.
An Analysis Of The 2001 Recession An Economic Analysis of the 2001-2002 Recession The recession is commonly defined as “Two or more consecutive quarters of a shrinking economy.” During the month of March 2001, the world’s largest economy - The United States of America - began experiencing a downturn, leading into a recession. (“Economists call it recession”). In comparing previous recessions that occurred, it appears that similar patterns exist also in the 2001-2002 recession. Such patterns start with increasing interest rates by the Federal Reserve Open Committee, proceeded by growth slowdowns, the fall of real output, and eventually the rise in unemployment. According to Robert E. Scott and Christian Weller, “further increases in real short - term interest rates herald a slowdown.” Further evidence that suggests a recession was on the horizon was information released from the National Bureau of Economic Research that states, “A peak marks the end of an expansion and the beginning of a recession.”(The Business Cycle Peak, March 2001.)
El Nino is the single largest cause of variability in the world’s climate change every 3 to 4 years and may last for 12 to 18 months. It means male child in Spanish and it refers to a weak warm current appearing around Christmas along the coast of Ecuador and Peru. It disrupts the normal Pacific Ocean circulation and is described as a warm event. On the other hand, La Nina is an opposite event, a cold event, from El Nino and it means female child in Spanish. It refers to the appearance of colder than average sea surface temperatures in the central and East Equatorial Pacific.
AT FIRST GLANCE, THE PICTURE LOOKS WINTER PERFECT. When asked to elaborate on the "catastrophic" warning, Brian Hoeth, a meteorologist at the service's southern regional headquarters in Fort Worth, Texas, said forecasters were talking about an ice storm that happens only once every 10 to 20 years for the area. Forecasters predicted crippling snow and ice accumulations as much as three quarters of an inch in area from Atlanta to central South
It is this strain that led to the Sichuan quake. The 2008 Sichuan earthquake occurred where the eastern part of Tibet, forced further eastward, overrides the Sichuan basin at a rate of about 4 mm/year. The rupture of the fault started in the mountains northwest of the city of Chengdu and then, over the next 50 seconds, traveled at least 200 km toward the northeast, tearing apart the land along the front of the mountain range. That at the epicenter, the depth of the rupture was only about 10 km below the surface. The amount of shaking correlates with rupture depth.
Also, the “hottest months in recorded history” have occurred in the past twenty years, while cold waves have seen a decrease (with the exception of a few extreme colds in the 1990s). In recent years, the last spring freeze has also been happening earlier, with
