This link will take you to one of the more illuminating articles of the year concerning the global warming issue. The message is that data is fabricated to allow access to the billions of dollars available for climate reasearch. This takes me back to the mid 1970’s when global cooling was the theme. (It now seems that was the correct theme as long term tree ring analysis shows a 2000 year cooling trend!!) I read that when the warming theory arose, it was because scientists were not able to make any money on cooling, so they wanted to try warming.
The competing theories were, for cooling, that particulates in the air blocked sunlight causing cooling, and, for warming, CO2 in the air trapped heat causing warming` From there, the battle was launched with the warmist faction prevailing. The image of drowning polar bears won over the polar bears are colder arguments. Of course, people would not buy the colder argument, although they did buy the argument that polar bears, that can swim fifty miles or more, were drowning. Ignorance is a large part of the warmist program. It is like Professor Gruber describing Democratic voters as ignorant, and these are the same people.
This ignorance allows warmists to deny the fact of no warming for 20 years by convincing themselves that the heat is hiding in the deep ocean. Just think about that for a ininute. A thermal unit of heat trapped by co2 in the atmosphere, dives into the ocean and moves down (even though heat rises) several thousand feet to “hide.”  Of course, this violates several of the laws of thermodynamics but that would not bother a warmist believer, embracing their religion. The other facts ignored and lies embraced by them are well known.  
This article shows one warnist theorist admitting his lie. There will be more. Michael Mann??
