The chimera of man-made global warming

We know that previous warmings have not been caused by rises in atmospheric CO2 (yet they're not fully understood); we know about the lack of detailed correlation between the carbon dioxide and temperature records over the last 100 years; we know about the absence of the model-predicted temperature hotspot high in the tropical troposphere.

Now in a post on Watts Up With That "232 complete and unadjusted GHCN station records are analysed for step changes in the period 1960-2010", and it is argued that:

• Abrupt changes in temperature linked with natural climate events may be widely responsible for the “global warming” during the second half of the 20th century
   
• 50% of sample stations have not experienced increased mean temperature (”warming”) for more than 18 years
   
• 70% of Europe stations have not experienced warming for more than 20 years.
  

In short, if the theory of CO2 induced AGW didn't exist and someone now proposed it, they'd be laughed out of court.

The politicians who pauperise us with their adherence to this out of date superstition deserve worse than our contempt and rage.

We need to tell them loudly and repeatedly that we are not fooled.
