  • Global Warming and the Greenhouse Effects
    Period: 4
    By:

  • Greenhouse effect, Climate change, and Global Warming
    Greenhouse effect- When the sun sends radiation to the Earth in waves, some infrared radiation rays make it through and get emitted by the surface. The radiation absorbed is then emitted at night and greenhouse gases absorb it and the atmosphere gets warmer.
    Climate Change- It can be a short term or a long term change in the earth’s climate, especially a change due to an increase in the average atmosphere temperature. For example it can also be caused by plate tectonics, Earth’s orbital motions, and solar activity and etc.
    Global Warming: An increase of atmospheric temperature due to carbon dioxide, pollutants emitted into the atmosphere.
  • How Greenhouse Gases, Climate Change, and Global Warming are Related?
    Greenhouse gases can be a cause of global warming with this, it increases the temperature of the atmosphere. With the higher temperatures of the atmosphere, climate change could happen.
    Carbon dioxide and pollutants emitted into the atmosphere  higher temp. in the atmosphere causing global warming  climate change…examples: hotter temperatures, melting of ice caps, etc.
  • Causes of Global Warming
    One cause is the increases of greenhouse gases.
    Some people believe that humans and some of their activities are a primary cause because they burn fossil fuels which pollutes the atmosphere.
    Also carbon emissions that get emitted into the atmosphere, too.
  • Consequences of Global Warming
    Environmental Destruction: Giant ice shelves in the Arctic are melting and the ocean is rising. Estimated 6 feet rising in 100 years. USA is responsible for 22% of greenhouse gas emissions.
    Health Risks: Malaria, dengue fever, and encephalitis are going to spread because of the spread of mosquitoes. The rising temperatures from global warming will make them spread to other areas.
    Catastrophic Weather: Super powerful Hurricanes will be made from very warm temperature areas and water. Since 1970, category 4 and 5’s have become a little more common. Pollution caused by humans might shift weather patterns and cause floods and severe heating.
  • Global Warming impacting Economy
    Huge amounts of money is going into clean energy projects, carbon trading, and environmental and energy hedge funds.
    More companies are trying to go green, so they will produce their products differently so people will buy them. People want to go green.
    Clean technology is now the third most popular for venture capital behind the internet and biotechnology.
    World Bank calculated 39 countries had lost five percent or more of their wealth from damages from carbon emissions and depletion or non-renewable resources. Also, for 10 countries, it declined a rang from 25 percent to 60 percent.
  • Ways to fight global warming
    Cars- Don’t drive cars a lot unless needed. You can walk and bike and use motorized scooter. Cars give off fossil fueled pollution into the atmosphere. Use transit to go to work because then there is less cars on the road.
    Bulbs- CFL light bulbs use 60% less energy and saves about 300 pounds of carbon dioxide a year for being emitted.
    Recycle- 3% of Greenhouse gas emissions through the methane that is released by decomposing bio-degradable waste. Recycling reduces the amount of that.
    Electric cars- Save up your money for one. No gasoline so no emissions of pollution in the air, runs on electricity.
    Carpool-Carpool with friends and co-workers. Less cars on the road so less pollution being given off.
  • Arguments against Global Warming
    One basic argument against global warming is that newspapers use the idea of it to sell their product
    Another, is that our most reliable sources of temperature data show no global warming trend.
    Is global warming a natural phenomenon.
    Some say that human activities threaten to disrupt the Earths climate, and some say humans have no part in it.
  • Our Opinions on Global Warming
    Our opinion is that global warming is a natural phenomenon and partly our fault.
    It is our fault because we emit these deadly pollutants into the atmosphere like carbon dioxide which is causing global warming.
    It is also natural because of the carbon dioxide that plants give off and solar activity.
    Global warming will go away naturally because before we had high temperatures on Earth before and cooler temperatures before so overtime Earth will solve this problem on its own.
