  • Global Warming is Not Real
    By Binghui, Brads and Kayla
  • Global Warming is a Natural Event
    Some scientists have suggested global warming is due to a natural 1500-year cycle.
    Climate change is much more likely to be part of a cycle of warming and cooling that has happened regularly every 1500 years for the last million years, authors and scientists Dennis Avery and Fred Singer said.
  • Continental Drift
    Continental drift is a natural event and it can change the climate.
    Over a long period of time, places move to colder regions of the globe other move to tropical regions.
  • Earth’s Motions ( Milankovich Cycles )
    The earth’s tilt changes 2 degrees. This change affects radiation received at different latitudes.
    That may make the climate warmer.
  • Solar Activity
    Sunspots cause the sun to give off more energy.
    Sunspots are cooler areas of gas on the sun surface, if there are not a lot of sunspots then there will be more heat.
    When the sunspots explode, they raise the heat.

  • Carbon dioxide
    100 million years ago there were six times as much carbon dioxide in the atmosphere as there is now.

  • The Video
    http://www.ossfoundation.us/projects/environment/global-warming/natural-cycle#section-0
    This website is talking about how global warming is a natural cycle.
  • Volcanoes
    Volcanoes throw 30 million tons of carbon dioxide, oceans emit 90 billion tons of CO2 and decaying plants throw 90 billion tons compared to just 6 billion tons of CO2 a year from humans.

  • Temperature
    Accurate satellite, balloon, and mountain top observations made over the last three decades have not shown any significant change in long-term rate of increase in global temperature.

  • Wobbly Earth
    Sometime the earth’s rotation is not perfect. Sometimes the earth wobbles, causing its temperature to change.

  • Methane
    Methane gas is released by dead plants in arctic tundra and wetlands.
    Methane is a greenhouse gas that causes the temperature to increase.

  • Water Vapor
    Water vapor is a greenhouse gas. We have more water than anything on earth.
    So, more water vapor in the atmosphere will cause the temperature to increase.
