Sceptical Views of Global Warming 2

  • Evidence from 600,000 years of tree ringing and ice core data show CO2 rises after temperature.
  •  100 year delay between. It could be down to Milankontehs tilt, wobble and stretch of the Earth.
  • The urban heat island effect makes data from weather stations located in towns and cities irrelevant.
