CLIMATE CHANGE


The Earth can undergo climate change in a variety of ways. One major way is by the means of “greenhouse gases”. In Earth’s atmosphere, certain gases (under label of greenhouse gas) trap the solar energy “reradiated” from the earth. This contributes to the warmer temperatures of the climate, and the habitability of the Earth. However, since the late 19th century, when the age of industry and fossil fuels really took off, global temperatures have been slowly increasing. From the late 1800s to today, the increase has been about 1 degree Fahrenheit (1). This is blamed on the excessive amounts of greenhouse gases being emitted by humans. To verify, we need to investigate the various types of greenhouses gases in the atmosphere.

The “greenhouse effect” is natural in nature. Without it, the Earth would 33 degrees Celsius cooler than it is now (3). That would kill majority of life on Earth, humans included.  The way the greenhouse effect works is similar to a blanket. The Sun sends solar radiation down to Earth. Some of it passes through the atmosphere. This radiation then proceeds to warm the Earth. After warming, radiation is reradiated back towards space. Most of this radiation then escapes Earth, but not all of it. The rest is trapped by the greenhouse gases, adding to the overall global temperature (3). Water vapor is the most abundant greenhouse gas. Think about the Earth, roughly 70% of it is covered with water. A lot of this water gets into the atmosphere and serves as a greenhouse gas. However, water vapor is versatile “gas”. In the atmosphere, it goes through loops. Water vapor blocks the sun’s radiation, turns into clouds, and then cools the atmosphere. It is difficult for scientists to measure accurately. (2) Carbon dioxide makes up the semi-majority of greenhouse gases and second most abundant. It is released into the atmosphere by humans exhaling, burning of fossil fuels, and even deforestation. Methane is another natural greenhouse gas, perhaps more potent. It is released into the atmosphere primarily by cows (passing gas) and the process of plant decay.  It only stays in the atmosphere for 10 years, “but traps 20 times more heat than carbon dioxide (3)”. Nitrous oxide is another gas that is released by human/animal waste. This gas can stay in the atmosphere up to 100 years. Ozone is a natural greenhouse gas by means of absorbing UV light from the sun. Ozone particles in the stratosphere absorb excess amounts of UV-B radiation from the sun. Upon absorbing, said radiation, they produce heat, similar to how a greenhouse gas traps heat (4). Fluorocarbons are more human responsible greenhouse gas. HFCs (hydrofluorocarbons), the substitute for the ozone-killing CFCs, are greenhouse gas material. Instead of killing the ozone layer, they heat up the Earth’s atmosphere (4).

Not all of climate change can be blamed on humans as most people would think. Volcanoes can be a big player in the “climate change picture”. When a volcano erupts, most people would think that just lava comes out. Lava is just a part that comes out, large amounts of gases and dust particles are also thrown into the atmosphere. Dust particles can stay in the air for days to months, depending on where they are in the atmosphere. During this time, these particles can block the sun and produce “cooling effects”. Following the eruption of the volcano “Tambora” in 1815, a severe cooling effect with cold temperatures caused crop failure in North America and Europe (5). Volcanoes that eject sulfur oxide/dioxide can affect the climate even more greatly. This sulfur oxide/dioxide reacts with water in the stratosphere to form droplets of sulfuric acid. Surprisingly, these droplets reflect a great amount of sunlight, producing an even greater cooling effect (5). A volcano can also contribute to global warming by ejecting mass amounts of carbon dioxide into the atmosphere (5).

RESOURCES AND HUMAN IMPACTS ON EARTH SYSTEMS

Energy is fundamental to human industry and technological development. We use energy from the earth to run our cars, power our buildings, and make our goods. More and more each day, humans are starting to realize the benefits of non-renewable energy. As or January 21st, 2009, around 13% of America’s energy comes from renewable-energy sources (7), the rest is non-renewable. Fossil fuels (coal, natural gas, oil) are a non-renewable energy sources that we depend heavily on as a society. “The world consumes over 85 million barrels of oil every day (over 30 billion barrels per year). The USA alone consumes over 20 million barrels per day (over 7 billion barrels per year).” (6). All this oil goes to produce things like plastic, and to power things like our cars. To understand why this outlook is bad, we need to investigate the “pros and cons” of each energy source, renewable and non-renewable.
http://www.horizontaldrilling.org/horizontal-drilling.jpg
Non-renewable energy sources are what have made America great, but are not the ideal energy source for future generations. These energy sources are cheap, powerful, and have already been ingrained into society. Where these energies fail is in the environmental impact. Fossil fuel is a major non-renewable resource that runs the world. It is a cheap energy source to gather, all that is required is for an oil drilling company to drill into an “oil reservoir” and “pump out” all the oil. To drill an oil well in Arizona in 2003 could cost anywhere between $400,000 and $1,000,000 (3). It is also very powerful and convenient, giving off high amounts of energy in a little package which can be transported anywhere easily. However, fossil fuels are a “dirty energy”. When fossil fuels are consumed, the by product is often a mixture of greenhouse gases, like carbon dioxide. These “greenhouse gases” trap heat in the atmosphere from the sun, too much of these gases heats up our planet and ruins the natural balance of the atmosphere (2). A simple look at Venus’ “hellish atmosphere”, with huge quantities of greenhouse gases, should show us this is a bad thing.
http://www.starlinetours.com/images/LasVegas/HooverDam-Front.jpg
Renewable energies are what governments today are striving to achieve (7). Hydropower, solar power, and wind power are three of the main types of renewable energy sources. Hydropower uses water to spin turbines to produce electricity. Solar power uses the energy from the sun to produce power by means of producing steam, or by means of photovoltaic cells which convert sunlight to electricity (8). Wind power uses wind on earth to turn turbines, which produce electricity in return. All these sources of energy have the benefit of being totally renewable by getting their energy from things like the sun (which will never run out in our lifetime, hopefully). They are also clean burning with no harmful byproducts, like carbon dioxide. The drawback to renewable-energy is the cost. Great hydropower plants like Hoover Dam, cost $49,000,000 to build (5).
http://earthcool.com/picts/deforestation-tree-removal.JPG
Human pollution through our energy sources is not the only thing impacting our environment. Deforestation is a huge problem in today’s society which impacts the four Earth systems (biosphere, atmosphere, geosphere, and hydrosphere). The definition of deforestation is the removal of trees on a massive scale on land. The first impact is on the biosphere. Many living organisms live in trees. When a whole area of trees is removed, these organisms lose their home and shelter. “Seventy percent of Earth’s land animals and plants live in forests...” (1). The second impact is on the geosphere and hydrosphere. With trees removed, there is a limited way of returning water vapor to the atmosphere above lush forest lands. With little to no water vapor, these lands can become barren deserts (1). The third impact is the atmosphere. Trees are natural carbon dioxide filters. Like plants, they consume carbon dioxide and produce oxygen. When trees are cut down, they release all the carbon dioxide they have captured, back into the atmosphere. This results in more greenhouse gases present in the atmosphere.

DEEP IMPACT: BAD ASTRONOMY

  1. One fact I thought would be true was the appearance of the asteroid in the night sky. This was true, that the asteroid headed for Earth would have been visible, but very, very, very faint. Leo would not have been able to see it like he did the stars.
  2. Another factual fact I got from the movie was that astronauts would be our only protection from an  asteroid. This is true in a sense because the space program would be the only organization capable of protecting us from asteroids. But astronauts are not really needed for the missles arnament. Sure, they could be there in case anything went wrong, but nuclear missles could be used with hard tip points to go into the asteroid and blow it up.

  1. A fact which I thought was false in the movie was that the asteroid would have no gravity. This is not totally true, but the gravity portrayed in the movie was way heavier than what it would be in real-life.
  2. A fact which I thought was false was that the people could watch the comet hit the Earth, safely. This is totally false. The comet would be moving so fast and be so bright, that it blind and kill you within hundreds of kilometers. No one could watch it safely.
Are the lunar landings faked? This is a tough subject to discuss since there is no real, proof. Sure, there is the tv and audio recordings. But are those faked? My reasoning is that it is not faked. Why would we as a country lie about something so great and pretend we did it? Are we that sad? I believe not.
From the website, I only retrived controversial information and back-and-forth opinions. This is still a highly controversial issue and no answers have been found or proved to convince EVERYONE.

CONNECTION:CLIMATE LABS

For Activity 1, we had to measure the "heat absorbed" by 3 different materials in pie pans. The materials were water, dirt, and sand. Our results were normal and as expected. The water rose and fell in temperature the slowest. Dirt and sand were about equal, both absorbing heat and cooling off fairly quickly. No material behaved out of the normal.

For Activity 4, we had to measure the heat inside 3 different "atmospheres". These "atmospheres" were bottles with different environmental qualities to them. The different materials played as different roles. The bottle played as the atmosphere, the paint played as clouds, and the water played as itself, or if you will an ocean/lake. The results were really suprising. Our bottle had all 3 of these qualities mentioned, and the temperature barely fluctuated at all. The temperature inside rose in the beggining at a steady pace upwards, but after roughly halfway through, it stopped. There was no change at all. I figured the temperature would rise inside because it was being baked by the light, or "heat source". The "clouds" must have done a good job reflecting the light.

These climate activities do show Earth's climate on a small scale fairly well. The big picture, however, is still way different in the actual breakdown of climate effects. Overall, small variables, small results. My climate topic is lightning. This would be a VERY hard topic, impossible really, to develop in "the lab". The only experiment you could do would be to test on particles in clouds getting charges on them, both positive and negative (recipe for lightning). No one could make a lightning cloud in the lab.

CLIMATE CHANGE

Climate change brings numerous questions with it. What will happen when the Earth is warmer? How will the ecosystem change if there is rapid warming? If the ecosystem changes, how will agriculture be impacted? If agriculture is impacted, what will happen the supply of food? How will climate change ultimately change human society?

"Frequent Questions." US Environmental Protection Agency, 19 Aug. 2010. Web. 17 Oct. 2010.
 
Rising global temperatures is a factor of climate change. The current scientific models availiable predict an increase of "3 degrees Celsius (5.4 degrees Fahrenheit) by 2100". With increased temperatures, there is drawbacks. Ice in the polar regions of the world will melt faster, and thus increasing the sea level. With increased sea level, many islands and low-lying regions of the world will flood. Hurricanes will also be stronger due to the would be increase of the sea temperature.

SEWER TREATMENT

The sewer treatment plant was a unique trip for me. The real shocker was that the smell wasn't really that bad. You would assume that  with almost all of the sewage in the Eaton Rapids area going through the plant, the smell would be atrocious. At the plant, I learned that the water goes through multiple steps throughout the plant. Some of these steps catch plastics and other things people shouldn't flush down the toilet. Most of the other processes let the heavy articles in the water either sink to the bottom, or float to the top. At these locations they are collected and dealt with appropriately. Another suprising thing to me was the amount of work microrganisms do to the water to clean it. This really shows how much we depend on mother nature in our everyday lives.

I didn't know a recycling plant for 1 and 2 plastics existed at that facility. My family goes through a lot of plastic bottles, especially at home. I might be able to get them to put it into a special container to deposit at the facility. My only complaint was that it could be more organized.

Posting on City Talk

  1. Mrs. Birerley, she was a project manager 
  2. The city upgraded the storm drain pipes to include filter for the storm water before it goes directly into the Grand.
  3. The water will be mostly rid of the oil, grease, and liter from the runoff of the pavements.
  4. The quality of our test will most likely improve will the reduction of runoff pollutants.
  5. I didn't know that they added parking lots that absorbed the water before it entered the Grand. Also I'm interested in the fact they said about bringing the "rapids" back into Eaton Rapids.
  6. My biobotte is doing very well. It has grown plants, which I didn't expect to happen. The phosphates aren't really affecting the bottle too much right now, time will tell though.
  7. For my action project we are doing it on pollution of water and solutions to it.
  8. Honestly, we have barely started.

Water Testing Connection

Our group chose the topic water pollution

For the action project, our group plans on helping solve the problem of pollution in the Grand River. We plan to do this by raising awareness of all the major pollution problems affecting the river. This will help the community know what harmful activities they are doing to the river, and what they could do differently to prevent said activities. Awareness and community involvement is the best solution because "many hands make light a task".

In our biobottle lab, we will be testing on how excess amounts of phosphates in the form of fertilizer or cleaning solutions affect water, plant, and maybe animal life. We will be observing how phosphates react to a water type environment. Things we might be looking for may include ph level, temperature, and even plant health.

The river test we were assigned was to test for phosphate level in the water, and our action project is on water pollution. These two things are connected because too much phosphate in water is considered pollution. Phosphates, in moderate amounts, is healthy for water and improves the quality. When phosphates enter water in an excessive amount, then there is a problem. Excess phosphates increase the amount of algae, which takes oxygen from the water. With little oxygen, any animal life in the water slowly dies off. This process is called Eutrophication, the aging process of water.  Humans are to blame for the excessive amounts of phosphates by fertilizer run off and the dumping of phosphate-rich chemicals into the water. Our action project is to stop the Grand River from going through this process before its time.

How we treat water in Eaton Rapids

Eaton Rapids water comes from 6 different wells. Three of these well are gravel wells 60 feet deep. These are the more monitored wells. The 3 other wells are rock-sediment wells, the water filters through the earths layers. These wells are below the Grand River, 300 feet deep. To this water they add different chemicals for different effects. Chlorine is added to help further "clean" the water. Fluoride is added to add bone-health benefits and dental benefits. Phosphate is the last chemical, and this added to prevent lead from leeching into the water from the pipes. The suprising thing I learned at the city water facility was the few number of people that took to run the facility. I thought there were only people going to be dozens of people to monitor such a crucial facility. Instead, there were only 2-3 people there. Lots of the systems were automated, and the others computer-assisted.

Water Treatment "Not Far from YOUR Home"

"[Eaton Rapids] water comes from 5 groundwater wells located in the northern portion of the city. The Iron Removal Plant removes iron and chlorine is added for disinfection, fluoride for dental benefits and phosphate for corrosion control."
http://www.ci.eaton-rapids.mi.us/documents/2009CCR_000.pdf

"Different treatment is used depending on the source of your water. Ground water taken from wells has been filtered through rocks, so it is usually quite free of particles. It can still contain chemicals and organic matter that must be taken out, though. If your water comes from a surface-water source, such as a river, some work must be done to get rid of particulate matter. In this case filters are used to screen out large particles, and at a minimum, chlorine is added to kill dangerous bacteria and microorganisms. Some systems have additional water treatment, such as adding chemicals to make matter bunch up and fall out of solution and adding chemicals to make the water less corrosive to metal."

My Carbon-footprint

1) http://www.nature.org/initiatives/climatechange/calculator/

2) This wasn't really a good site for anyone that doesn't own a home or know what they buy for maintaining their home. Even the personal calculator asked house based questions.

3) My carbon-footprint, while living in my parent's house, is 16 tons of CO2 every year.

4)
a) Three ways of reducing the carbon-footprint for myself would be to: reducing the amount of "vampire" devices I own, to purchase electronics that have more "environmentally-friendly features", and not use paper-bags everyday for lunch.

b) Three ways of reducing the carbon-footprint of my school would be for the school to: offer tray recycle bins at lunch, invest in solar panels atop the roof, and have the school buses run on clean fuel.

c) Three ways for the Eaton Rapids community to reduce its carbon footprint would be to: offer more recycle facilities, cut down on the amount of plastic bags (Family Fare?), and to offer more knowledge on how to "go green" to the community as a whole.

5) Everything we do as humans goes back to our local water source. Water is the "number 1 key" to survival. No usable water means death to all living beings. The amount of toxins and waste we submit to our water is not kind to our "1 key". This carbon footprint calculator should be a wake-up call to most people about how much pollution they admit in everyday life. The more they do to reduce pollution, the better quality our water will be, and thus the better quality our life will be in the long run.

LIGHTNING

Lightning strikes all over the world, very numerously in fact. Satellite data suggests there are "3 million lightning flashes worldwide per day". It can happen anywhere there is a storm cloud brewing.(4)









Storm clouds are generally cumulonimbus clouds. These are massive, towering clouds often reaching high in the atmosphere. They usually form when a cold front meets a warm front. The air also has to be moist enough for the clouds to form. Inside the clouds there are strong updrafts. This is the start of how lightning is made. (3)






The exact science how lightning is made is a mystery. There a few theories, but perhaps the most popular one involves ice particles. When a cumulonimbus cloud reaches a precipitation capacity, water is carried up the cloud by the updrafts. Here the water collides with ice particles in the upper portions of the cloud. These collisions supposedly create a charge, which the negative portion going towards the bottom of the cloud and the positive towards the top. The difference in charge becomes too great, and thus, lightning is born. (1)








To summarize, for lightning to exist, there must be a cumulonimbus cloud. Inside the water must collide with enough ice particles to make a great enough charge. If a cumulonimbus cloud produces lightning, then it is classified as a "thunderstorm". (3)














On a side note, lightning ALWAYS exists with thunder. (1)





Technology does exist that detects lightning, but it is hard to predict lightning, for it is random. The detected lighting is almost always CG (cloud-to-ground) Lightning detectors have been in place in the US since the 70s. These antennae detectors are hundreds of kilometers apart and detect the radio-frequency pulses that lightning gives off. The location is where the vectors intersect. Since 1994, this system is one combined network run by Global Atmospherics Inc. These instruments provide lightning strike indicators to provide early storm intelligence and give people an early heads up. (4)











It is estimated that $4-5 billion damages occur each year because of lightning. Money spent to safeguard sensitive equipment from lightning damages is also enormous. Between the years 1979-2008, lightning killed an average of 58 people each year. Lightning can travel through a power line to an electrical appliance, and anyone using that appliance. It can also travel through plumbing pipes and water to a person in contact with either of those, examples primarily being shower and bath. One out of 5 lightning strike victims die, and 70% of the lucky survivors suffer serious long-term after effects. (4)








Lightning also affects the environment around us greatly. Forest fires are generally caused by lightning strikes to a dense group of trees. Power outages can be traced back to lightning hitting a power grid. However, not all the affects of lightning are negative. Lightning maintains the Earth's electricial balance. It returns the negative charges back to the Earth. Lightning also produces o-zone, which is necessary for the Earth's protection against the sun's harmful UV rays. (1)
