Global warming and Elvis's death

In the family are 4 PhD's, one works extensively with statistical analysis.  A few days ago he sat quietly as a history professor ranted at a lunch about the global warming hoax, it stopped warming he said, it's cooling.  Annoyed by what he suspected was pure bullshit he decided to find out.  Not being a climate scientist (nor was the buffoon), he could however look at the data and evaluate if it is is presented correctly.

He spent most of a weekend downloading and studying observed and recorded data from NASA, universities, and scientific journals.  He also looked at denier's presentations.  

First thing he noticed was, all of the data from the first sources stands up to statistical analysis.  So far as he could tell, the conclusions drawn from the data appear correct and meet all the tests for good and logical results.  

Second thing he noticed was deniers present almost no data, but plenty of charts and conclusions.  Virtually none of it would get a passing grade in a high level college statistics class, not only since there is so little info given to base it on.  Most all of the graphs either drop data, reset base values, manipulate others work, or just plain make shit up. 

He said he suspected deniers were doing this, so it was no surprise, but to actually go over some of the work and see how absurd it is was very disheartening.  

Now, the other interesting thing is, we also have a PhD climate scientist working for NASA in our extended family.  His comment to the statistician, there are lots of people who still don't believe smoking causes cancer or that Elvis died in 1977.
