How did you do that?

I'd like to invite anyone interested in investigating these details to check the following:.

• Pick a date and a range to evaluate. 1970, or 80, etc. 30 yrs, 40 yrs, etc.
  
• Find a measurable factor to track:. sea level rise, temp, etc.
  
• Find an original source document that can't be edited after the fact (newspaper, movie, book (revision, date publishing date is crucial).
• Record the predicted factor: sea level rise, temp, etc.
  
• Find current sources and document the actual factor: sea level rise, temp, etc.
  
• Compare predicted vs. actual.
  
• Done.
  

On a personal level I would also be very interested in what software you used in your analysis.

Fancy software like minitab or JMP to analyze the facts.

Simply review the historical record vs. predicted. It's basic arithmetic, with original sources.

One last note:. You may recall that man made climate change was one called man made global warming.

They changed the name, because the warming trend was bogus, and indefensible.
