  18. 18. www.climatechangefraud.com<br />Website set up to counter climate change arguments from websites such as ipcc and climate org.<br />Limited number of contributors<br />Source reliability is questionable (Thomas Richard Editor)<br />Has some reputable contributors such as Roy W. Spencer, Ph. D. (former NASA scientist)<br />Large number of links but not so reputable<br />Individual assessment as opposed to task force<br />Maintained by advertising and donations<br />
  19. 19. http://www.skepticalscience<br />Huge amount of links to both reputable and unknown websites<br />Whole website is maintained by one man (John Cook – Solar Physics Major)<br />Allows for open discussion<br />Provides both a skeptical view and scientific view of climate change issues<br />Non-profit website (donation driven)<br />
