Video chapter 15
interesting video! i learned about the energy sources,which are very important for us.Also the environmental,political and other impact of fossil fuels.

December 3rd
For me, what we learned was just a review from my Metheorology class. I love that course!
Class December 3rd
I read up on the chapters and found it extremely interesting when I came across chapter 14. I liked learning the factors of climate change. Some of the factors such as something as consistent as ocean circulation can exchange heat within the atmosphere affecting the climate/weather. I also liked reading up on North American Deep Water (NADW). I believe I have understood why it has become vulnerable with something so little as a disturbance within the thermohaline circulation. Reviewing the projected precipitation changes was fascinating because we are the cause of these changes and if something does not change soon then we will have to face the inevitable consequences. The ways to stabilize or slow down these rapid climate changes that we have been experiencing are ways that seem so simplistic. For example, buying a hybrid, drive less, use public transportation, etc.

On the 3rd of December I was not in class; however, I read the chapters and did not realize that London “created a congestion- charging” program. I believe that it is slightly unfair to people with lower income that need to work in the central city. As a whole; it is more intelligent to have people pay to enter the CBD because nobody wants to pay more than they have to. I was also interested in learning about the terms normal conditions, and thermal inversion. When looking at the thermal inversion diagram, I was able to understand what temperature profile Beijing and Hong Kong goes through. They have a humid climate and when the heat rises; the area receives an inversion layer where the pollution is trapped around the city.
What I learned from chapter 15
I learned that there are three major types of fossil fuels in the world; which consist of coal, natural gas, and crude oil/ petrol. The United States contains much of the world’s coal as Russia does with natural gas and the Middle East with crude oil. Coal used to be the main source for heating homes and fueling machines such as ships and trains. Today, coal is used to generate electricity. In the state of Pennsylvania, a tire was on fire and happened to go underneath a town in a mining shaft. The town, Centralia caught on fire and till this day is still burning. I never knew that before and found that quite interesting. The second type of fossil fuel is natural gas. This fossil fuel is located inside the pores of the bedrock and can only escape outward by a pump. Salt water is used to pump out the natural gas. This practice is known as hydraulic fracking. A third type of fossil fuel is a liquid and is known as crude oil. Saudi Arabia is the largest producer of petrol in the world. The largest consumer in the world is the United States. I was surprised to find out that the US uses almost a quarter of the world’s petrol. I was also surprised to find out that we have already consumed half of the world’s reserves.
I agree that Americans are not used to taking mass transit. We like to have the ability to do things on are own time; however, I believe that the mass transportation that we do have can be unreliable. Many different types of people travel by mass transit in Europe because it is an easier and cheaper form of traveling. In the US, mass transit is not an easier form of transportation.
Much of the rail lines that we did have were abandoned to creating roads for the military/our automobiles.
What I learned from chapter 16
It seems that scientists are taking the time to research cleaner and more efficient ways for people to use power. I learned that there are various sources of renewable energy that can replace the use of fossil fuels. The use of hydropower, biomass, and bio-power are ways to avoid the usage of fossil fuels that can harm the environment in a negative way. However, renewable resources still have negative impacts. For instance, hydropower can reduce fish populations by the stirring up of sediment. Solar energy and wind power is also a cleaner for people to gain power. I believe that use of solar and wind power is a great way to receive energy.
What I learned from chapter 17
People create an extraordinary amount of waste. Some how, I was not surprised that the US throws away almost 5 pounds of rubbish a day. I think the only way to deal with our waste problem, is to produce less! I don’t believe that the use of incinerators is smart because the ash still has to be sent to a landfill. It also creates pollution in the atmosphere when it burns. The use of plastic is extremely high and we should reduce the amount created. For instance, shopping bags are not necessary needed. I believe many people today are aware of the problems we are creating with landfills. In some cases people are trying to be less wasteful; however, it needs to be done faster and more efficiently.

Waste and new tech
The waste industry is a problem you never really think about.Where all of the trash goes and what is done with it,but science is providing some viable options for its future.
The renewable energy video was very informative,all the diffrent technologies coming down the line.The one converting thermal water from the sea to energy looked really interesting.Solutions are starting to come some I would never have dreamed of.

last video comment
Interesting video, i learned that waste can be reduced by manufacturer's its so interesting because in my country they use plastics a lot and it cost less to manufacture the plastic.
