GVC: Global Warming

Page One Draft

See here work of Muir high school students for GVC 2009.

Students will put this work and more onto an orginal web site with students in Japan and Slovakia by March 15, 2009. Good luck!

 

 

San Diego Rivers, By Nada

The Colorado River now goes to the San Diego river instead of the Imperial Valley River . The San Diego River was about 440 square miles. Just like every place there is a lot of water being used everyday in San Diego . San Diego County has a semi-arid climate and a very small supply of local water. Between 75 and 95 percent of the county's water is imported.

Water Conservation By Liualii Fitiuta Leasau   There are many ways to conserve water in your daily life whether it is turning the water off while you brush your teeth or only washing your clothes when you a large load. Everyday the average American uses between 80-100 gallons of water a day, according to the USGS. We should try and conserve water because although 80% of the earth is covered with water only 3% of it can be used as a fresh water resource. Although there are alternatives to conserving water such as desalination and cleaning plants they have major flaws. Desalination uses our oceans water but what happens when all our salt water is gone and desalination kills 2.5 pounds of fish per day that's 912.5 pounds of fish per year, also fresh water is being used faster than Cleaning plants recycle water that comes from your house so you might be drinking toilet water.   There are more ways that you can conserve water such as buying low flow shower heads, faucets, fixing a leaky faucet (which wastes 2,700 gallons of water), take shorter showers, when washing dishes by hand, fill one sink or basin with soapy water quickly rinse under a slow-moving stream from the faucet, defrost your meat in the fridge the night before, Adjusting your sprinkler so that you waste less water.

Other States and federal Efforts

The Coastal commission is one of the three state agencies that administers the federally approved California Coastal Management Program (CCMP).The CCMP incorporates many of the Coastal Commission's authorities under the California Coastal Act.The California Coastal Commission is a member of the Coastal States Organization.The California Coastal Commission is a member that participates on various CSO subcommittees.The California Coastal Commission is one of 34 federally approved Coastal management programs.The CSO Climate Change Work Group, which has completed a report about challenges coastal management face in adapting to the impacts of climate change.

 

Water Department

A water conservation representative tours the property and points out leaks and water saving opportunities. The program educates the tenant on the importance of water conservation. Since 1998 the city has hosted workshops for over 3000 students in San Diego . The importe sources count for more than 95% of the regions water supply

Facts by Ryan

  1. Species are restricted and fragmented by natural and human causes.
  2. Invading species have come in, pushing native species away,
  3. Species are trapped because migratory corridors are blocked.
  4. Animals near the borders of countries are more affected
  5. Climate change could make opportunities for weeds and pests to spread.
  6. Increase in fires from climate changes threaten species
  7. Trees and forests have adapted to climate conditions.
  8. Trees adapt to warmer and wetter climates.
  9. Forest would become denser in wetter climates
  10. These changes could happen during the lifetimes of today's children.

WATER ARTICLE Nada Nour

California 's major initiatives for reducing climate change or greenhouse gas, have outlined in assemble Bill 32, trying to reduce passenger car GHG emissions, to 1990 levels by 2020. A reduction of about 30 percent and 80% below 1990 by 2050. California produces about 1.4% and 6.2% of total U.S greenhouse gases. Governor Arnold Schwarzenegger had executive order, to further advance clean renewable energy and other solutions to lower states greenhouse emissions. California Global Warming solutions, 2006, established first comprehensive program of regulatory and market mechanisms to achieve great cost effective reductions of GHG, and it is the first in the world.

Hydrogen Vehicles: The Future of Transportation, by Nick

What is hydrogen and where does it come from? Hydrogen is the simplest and most plentiful element in existence. It is composed of one proton and one electron revolving around that proton. In hydrogen's gas state it is colorless, odorless, tasteless, non-toxic, and invisible when it burns. It's not necessarily a fuel but a energy carrier. Hydrogen is found in the atmosphere due to it being lighter than air and in all biomass.

What is a fuel cell? A fuel cell is able to generate electricity from a catalyst facilitated chemical reaction between hydrogen and oxygen ion with in a cell. Every fuel cell has two electrodes, one positive and negative ion. Each fuel cell also has an electrolyte, which carries electrically charged particles from the anode to the cathode, and a catalyst which speeds up the process. Fuel cells also require a fuel, in this case oxygen. The great allure of hydrogen is that it is able to generate electricity with a very small amount of pollution. Much of the hydrogen and oxygen atoms used in generating the electricity fuse and become the harmless byproduct we know as water.

How does fuel cells work? Hydrogen atoms enter at the anode where a chemical reaction takes place and strips the atoms of their electrons. The hydrogen atoms have now become ionized and carry a positive charge. The negatively charged electrons now provide the current. If AC is required, then the DC output must be put through a device called an inverter.

Hydrogen in vehicles: As of now there is around 400 to 500 hydrogen fueled vehicles in the U.S. Most of these vehicles are in California and are buses and other automobiles powered by electric motors. These vehicles carry either hydrogen gas or liquid and convert it into electricity for the motor using fuel cells. Only a small percentage of hydrogen vehicles burn the hydrogen directly. Currently the cost of producing fuel cells holds back mass adoption of hydrogen in vehicles. But as more companies invest in the technology for it's many benefits the price will fall enough for it to be in the hands of the consumer in a matter of years.

10 facts, by Nick

- California , per capita, emit less GHG than the average American but is still much more than the world's average.

-Precipitation in California has decreased by 20% in most part of the states.

-Based on current projection California 's temperature could increase by 5 degrees by 2100

-In the Bay Area and the Central Valley the concentration of ozone could increase by 20%

-Ground ozone has been shown to cause health problems.

-Ambient ozone also reduces the crop yields and hurts the natural ecosystem.

-The agriculture industry in California is a 19 billion annual industry.

-The main crops are cotton, wheat, hay, tomatoes, and oranges.

California 's seasonal pattern runoff to reservoirs could be susceptible to climate warming.

-Mass migrations and extinction could occur due to climate change.
