Article 1
 Genetically Modified (GM) Foods.
  • Consumption of GM foods
  • Consumer image of GM food depends on its sale
  • Consumer adversion to labeled GM food
  • GM food sells better when the market is saturated
  • Consumers perceive GM foods as different than
Article 2
  Light and photosynthesis in aquatic ecosystems

  • Plants need Solar energy, CO2, minerals, water
  • Water absorbs and scatters light
  • Light absorption varies with depth
  • Aquatic plants are less effective than land plants
  • Hydrologic Optics
  • Light is measured in "quantas"
  • The average cosine for downwelling is equal to the downward irradiance divided by the downward scalar irradiance.

My thoughts on the thing we saw

Nate Lewis is an amazing man. Simple as that.

At first I thought this would be just another alarmist weirdo talking about how "Were all gonna die, and theres nothing we can do." I was wrong. I do not feel that we as class understood the sheer magnitude of what he was saying when he said the word Terawatt. A terawatt is a ridiculously huge amount of energy, enough energy to power 10 billion 100 watt light bulbs. I am just purely amazed by the amount of power needed to fuel humanity. I found it compelling the way he introduced the facts and odd that there are so many alternative power sources that just simply can not provide the 13 TW we need to survive. The only feasible power source is in fact solar power.

The sun provides, as Nate Lewis said, about 600 TW of reasonable accessible energy. to put that HUGE number into scale. 600 TW is 6.0 × 10^14 watts, if you had a rope that was 6.0 × 10^14 MILLIMETERS (0.0393700787 inch) It would wrap around the world 1498 times! That is HUGE and that also means that the amount of power we can get from the Sun. but for me the question is, how do we turn that power into something that wont strain our infrastructure. I beleive he was right by saying that chemical energy is the way to go but that is much easier said than done.

Holy 3 annotated sources on climate change Batman!!

Source 1:GWsource_1
Historical CO2 Record from the Vostok Ice Core 

  • Shows co2 data from the past 400000 years
  • Shows an upward trend in recent years
  • one of the main components in the graphs used by al gore
  • this data comes from antarctic ice cores going down 3304m
  • takes into account age of ice and air from samples

Source 2:GWsource_2
Historical Isotopic Temperature Record from the Vostok Ice Core  

  • uses the Vostok ice data to calculate temperature data
  • temp data goes back over 400000 years
  • has no temperature variation in the last 120 years
  • a brief look over seems to show a large amount of negative numbers
  • this data is used as the standard for graphics on climate change

Source 3:GWsource_3
Estimating the uncertainty of the Mann et al. (1998, 1999) reconstructions 

  • bring into question the accuracy of the Mann et al study
  • Defines the complicated terms that relate to error in a way that most people can understand
  • shows a similar but different trend than the one seen in AIT 
  • Admits to possible error in his data and asks for reviews to clarify
  • brings into question weather the smoothing models used on the graphs change the outcome
  • bring up possible errors and solutions with graphs and data readings.


I believe that by using the same sources that were used by the scientists, i will be able to create a balanced  set of data that are not influenced by media. In my senior project I will be able to use this data to make predictions about the future and the effect that climate change will have on human life.

I also included a media article because it shows a good way for me to find my own data. I admire the way the the author of the JunkScience website used data to come to his own conclusion without the influence of data or "facts" that mainstream media gives. This makes his finding a little more reputable.

    KA BOOOM

    Cherimoya is deciduous shrub or small tree that reaches up to 7 m tall. The tree flourishes in the coastal lowlands of Ecuador; is rare above 5,000 ft (1,500 m). In Guatemala, it is nearly always found below 4,000 ft (1,220 m It is sensitive to frost and must have periods of cool temperatures or the tree will gradually go dormant. It is cultivated in many places throughout the Americas, including California. Cherimoya's prefer a summer temperature of 65-80F, and a winter temperature of 41-65F. Cherimoya an be grown by seed, grafting, and air layering. Seedlings with 70F bottom heat germinate in about 21 days. Without heat, seeds may take 1-2 months for germination. Flowers are almost never pollinated by their own pollen, and without proper pollinators which do not exist outside its native range, cherimoya's must be hand pollinated. Pollen is generally collected from a few male flowers and stored in a small bag while it is used to pollinate female flowers. Pollen cannot be stored for more than a few hours before it loses viability. Flowers bloom from late winter to early summer, followed by fruit which ripen from October to May. Fruits are large, from 4-8" long, and sometimes weighing over 5 pounds. Harvest fruits when skin turns slightly yellow or pale green, or when skin gives a little to touch. The soil should be a porous medium that retains some moisture, but also maintains air pockets within its structure. It does best in low-lying, deep, rich soil with ample moisture and good drainage. A peat-based soil mix with sand or perlite added is appropriate. Soil pH requirements 5.6 to 6.0 (acidic) 6.1 to 6.5 (mildly acidic) 6.6 to 7.5 (neutral). The seed of this fruit are poisonous and can be used to kill insects.

    BLAH!

    Population: Enough of us now


    The purpose of this article is to point out how population has been influenced by external and internal forces and how that will play a role in the future

    http://www.newscientist.com/article/mg20327271.500-population-enough-of-us-now.html?full=true&print=true

    • By 2050 there may be about 35 per cent more people on Earth than there are today.
    • More people mean less food, less water
    • There are only two ways by which population can stop increasing: a falling birth rate or rising death rates.
    • Rise in death rates in southern Africa and Russia
    • Indian Ocean tsunami killed nearly 250,000 people. Another 160,000 died that day of other causes, and the day's 370,000 births couldn't compensate
    • 70,000 deaths caused by the atomic bomb dropped on Hiroshima, Japan, on 6 August 1945 outweighed the population growth of around 60,000
    • the Black Death of the 14th century, which killed 75 million people and reduced Europe's population by 30 per cent.
    • after 2050 the world will enter a new era when the population will shrink on many days.
    • We will simply be having fewer children.
    • There has to be a recognition, at the highest political level, of the importance of reducing birth rates
    • Uganda's population,  growing from around 33 million today to 91 million in the next 40 years
    • 2.3 billion people likely to be added to the human population by 2050



    Addressing Our Global Water Future
    Center for Strategic and International Studies (CSIS)
    Sandia National Laboratories
    http://www.sandia.gov/water/docs/CSIS-SNL_OGWF_9-28-05.PDF


    This study is about the management of water resources in the future

    Many efforts over the past twenty-five years have focused on alleviating water
    scarcity and providing clean drinking water and sanitation to effected populations
    across the planet. These efforts provide valuable lessons and successful models for
    new strategies and actions for new levels of crisis in the future.

    At issue with industrial facilities are the quantities
    of water withdrawn and the quality of water returned to the natural water system.
    Industrial withdrawals of water are expected to rise by 55 percent from 752 km3 per
    year in 1995 to 1170 km3 per year in 2025

    this increase will come from the developing world as countries continue to industrialize.

    Overall, about 80 percent of the world’s electricity production
    comes from nuclear and fossil fuel plants, where large amounts of water are used to
    remove waste heat from the processes. Several closely linked factors determine the
    potential impacts on associated water demand

    Why Britain faces a bleak future of food shortages

    http://www.guardian.co.uk/science/2009/dec/13/britain-faces-food-shortage

    food shortages are a result of too little water and too many people. This article talks about the changes that need to happen in order to sustain life.

    • Wheat prices across the globe soared by 130%, while shopping bills in Britain leapt by 15%.
    • a global food shortage would drive up import costs and make food more expensive
    • "We are going to have to produce as much food in the next 50 years as was produced over the past 5,000 years. Nothing less will do."
    • bluetongue disease, a virus that affects cattle, sheep, deer and goats and is spread by midges.
    • Other diseases like epizootic haemorrhagic disease (EHD) and African horse sickness are also spread by midges and threaten Europe and Britain
    • About 40% of crops in Britain are vulnerable to destruction by weeds, fungi and insects,

    Writeup

        100 years is a ling time for humanity. 100 years ago, polio threatened to wipe out thousands and thousands of people. The outlook was bleak and there were rumors that the united stated would never recover. 100 years in the future, the world will be a much different place than it is today. Food will be scarce and water will be in high demand, no doubt if wars have been fought over oil, wars will be fought over food and water. Humanity will be shrinking as a result to these non prime conditions. The reason for these shortages all stem down to population, in the next 50 years our population will grow to nine billion unlike polio however, population growth has no vaccine.

        I have had many ideas about what I could do to combine all of these idea into one product. I have come up with the idea of playing into the template of "yesterdays tomorrow". The house of tomorrow videos were once a platform used to showcase the technology that a company could provide. I want to make new house of tomorrow, but tomorrows house of tomorrow. Rather than diving into the bleakness of what possible futures we could have, I plan to make a house of tomorrow based in 2110 that showcases the perfection that 2120 will bring. Through the presentation the inherent issues of this dystopian future will become painfully apparent. Item such as in home food synthesizers will promise to alleviate the rubber taste of "normal" test tube meat.

        If population will rise to 9 billion by 2050, and that population increase alone, threatens to destroy our current way of life, If we are to believe that industrial withdrawals of water are expected to rise by 55 percent , if we are going to have to produce as much food in the next 50 years as was produced over the past 5,000 years. If all of these things are true, then this means that be 2110 our world will be transformed and altered beyond our wildest dreams

    Farmer in Chief

    We live in a world full of warnings and apocalyptic claims. Growing up in such a world, has numbed me to the alarmist theories and claims that are so frequently made. So it comes as no surprise to me that, upon first scanning the article by Micheal Pollan, I was skeptical. I was skeptical that so much of our society is so intertwined with the food industry.Upon deeper scrutiny, however, I noticed that this article was so much more than simply a warning but more of a wake up call.

    We had focus in class on "junk food" and though even the text pointed out that the term is one of ambiguity, we never seemed to grasp that fact in class. The focus of our classroom discussion, the prohibition of junkfood, was met with both proponents and opponents. I was on the the opposing side and throughout the conversation, I started to grasp the full gravity of the situation. Americans as a race, are so ignorant they simply cant see change as a reality.

    As a classroom of people who come from the varying backgrounds of San Diego, we represented a sample of America. As a sample of America we couldn't even come to a conclusion on the outcome of junk food. I do not believe we can decide for our selves.

    My Farming History

    My family history is a long winding one, where the soil is rich and fertile.

    In the begging there was my great great grandfather Eirek Vigoren, a man of many seeds. In the great land of Bemidji Minnesota, he grew many crops and raised cows and chickens.

    Then we progress to good ol' Elmer Vigoren my great grandfather,  Also a farmer he grew cattle, wheat and corn.

    and now my grandfather, His responsibilities lied in taking care of chicken and milking cows. When he was 12, a tornado destroyed his family farm and he moved to california
