Anti or Pro Global Warming
I am kind of in the middle. Some days it is really cold and then I see the ice in Antartica melting so I am not really sure.

Global Warming
1) Causes- The causes of global warming are trapping the incoming and outgoing solar radiation by natural greenhouse gases in the layer closest to the Earth, the atmospheric layer. Pollution is also another cause because when we burn fossil fuels, this causes pollution and fossil fuels give off C02 gas. (http://library.thinkquest.org/J003411/causes.htm)
2) Facts- Some effects are the climate could change and there would be a big shift in major agricultural areas. An example is where the Wheat Belt in the U.S. could get less rain and turn warmer which would endanger their grain production. Food experts think that there will be a decrease in the world's grain by 2030. The U.S. and the Mediterranean region of Europe would turn warmer and drier which would make more watering and taking car of crops. The warmer areas would have a higher sea level and oceans will warm. Polar sheets of ice and mountain glaciers would melt. Little increases would endanger low-lying islands because they might flood.
3)Controversy - People are arguing about limiting greenhouse gases. The U.S., Japan, and Canada all agreed to a reduction of greenhouse gases below 1990 levels. Even though the U.S. agreed, they emitted the larges abount of greenhouse gas per year. People want to limit greenhouse gases because they are one of the number one causes of global warming.

Today in class we reviewed everyone's powerpoints. Here are my notes:
Solar energy-
• Takes pressure off of natural resources.
• Sun emits radiation and this is re-radiaion trapped by the clouds which makes life possible on earth.
• Responsible for weather patters and ocean movement.
• Clouds and wind can prevent the Sun's energy from reaching the Earth.
• More reaches tropics than northern Alaska.
Latitude-
• The tropics are much warmer because of curvature of the Earth.
• Measured in degrees.
• Helps determine what the climate is like.
Interaction Between Land and Water
• Land areas heat and cool faster than bodies of water which is why the temp. is hot in the summer and cold in the winter.
• Continentally- inland climates with hot summers and cold winters.
• Maritime Climates- that are close to ocean with cool cloudy summers, and cold winters but not freezing.
• Global arrangement of continents has a big role on the world climate.
Global Pressure Patterns
• Earth is unevenly heated.
• Large oceanic cells expand during warm summer months.
• Enlarged cells make rainless summers.
• Typhoons are formed in Asia.
• Hurricanes are formed in North America and Caribbean in summer months.
• Patterns depending on the seasons.
Global Wind Patterns
• Trade winds- warm low breezes that blow most of the time.
• Wind is blowing all the time.
• Different wind patterns like trade winds, doldrums, prevailing westerlies, polar easterlies.
• Air flows from high pressure to low pressure so winds flow into low-pressure cells.

Today in Class We...
Today in class we finished watching the movie about Hurricane Katrina. We discussed it on todays meet.com. Here are my notes:
• They were tracking the storm in advance.
• People still stayed even though there was a big warning.
• Was a category 1 4 days before it hit New Orleans.
• The army stayed out of the way of the storm but stayed to check the Mississippi River and check the levies.
• Mississippi got hit as well from this storm.
• The city pumps designed only for rainfall, could not take all of the flood water.
• 75% of New Orleans was under water.
• It took over a month to get rid of all of all of the water.
• 60,000 houses were beyond repair.
• 1,300 people died just in New Orleans.
• The levies were under designed.
• They were tracking the storm in advance.

Notes on Global Warming
• Human settlement and food production are linked to the weather and climate.
• If a drought is in one part of the world, the socioeconomic repercussions are all over the world.
• There are 5 main factors of climate: solar energy, latitude, interaction between land and water, world pressure systems, and global wind patterns.
• The natural process of atmospheric heating is the greenhouse effect. It traps the solar radiation in the lower atmosphere that makes a warm envelope surrounding Earth.
• Interaction between land and water- land areas heat and cool faster than water which is why the temp. extremes from hot summers and cold winters away from coasts.
• Continentality- to describe inland climates with hot summers and snowy cold winter.
• Maritime climates- those close to the ocean have cold cloudy summers and winter that are subfreezing.
• Global Pressure Systems- Uneven heating of Earth because of latitudinal differences and the pattern of high and low pressure cells that drive the world's wind and storm systems.
• Global wind patterns- pressure systems that also produce global wind systems.
• Air flows from high-pressure to low pressure.

Debate over global warming
Here is a link to a website about global warming: http://42explore.com/globewrm.htm
An issue people are debating is... What is the cause of global warming?
Some people argue that global warming is man-made. They are called believers. Others called skeptics say that the temperature change is natural

Today in class we watched the end of the movie. We also talked about the question "Why won't the Nuginians just move?" I believe that they won't move because they like the way they do things and don't want to change. They don't have wars or violence with the way they do things. The bottom line is that they are happy.

• People of European origin have dominated the globe.
• Nuginians learn quick.
• Why do Nuginians have less cargo than us?
• People hunted the same way 1,300 years ago.
• Middle East was far less arid 1,300 years ago.
• They eat saygo from the saygo trees and cereal grasses.
• They had a "refrigerator" called a granary at the center of the town that stored things like wheat and grain. ( A long time ago.)
• They were the first farmers.
• Saygo-can't store this. It will only last for about 3 days.
Cereals (grain and wheat)-can store grain and it's still edible for a while.
• Plant Domestication- Change the crops.
• In the Highlands of Nuginey, the farming was different and not as good as in the Americas and Africa.
• In the Americas, they grew more healthy and nutritious things.
• Geographic Luck-

Today in Class we... 10-1-09
Today in class we watched the movie and tooks notes again. We disscussed what we thought about it.
What we did in class today... September 30th
Today in class we watched a movie on how life is like in Nuginia. Their world is a world away from the U.S. physically and with the way they live their lives. We had to take notes on it and also use today's meet.com which is like twitter to ask questions and comment on the movie.
