Quote:Ok, so before we get into the science of climate change, we need to lay some ground rules. The tool we will use to get us to the conclusion that "Anthropogenic global warming is really happening" will be logic, specifically a formal deductive argument. A good deductive argument necessarily demands the truth of its conclusion.


How does it work?


A deductive argument must have at least 2 premises and 1 conclusion which follows from the premises. If the premises are true, the conclusion's truth is guaranteed.


The most famous example:


Premise 1: Socrates was a man.


Premise 2: All men are mortal.


Conclusion: Therefore, Socrates was mortal.

Is everyone still with me? Speak now or forever hold your peace.

 

I'll play.  I'll write it out as a computer program and we'll look at the result.

 

//  Is global warming happening?

if (global_warming)

    {

         manmade();

     }

else

     {

          return 1;

     }

}

 

The result of the program is going to return 1 which is not a good return on a Unix system.  It will never call the manmade() function because it fails the first test.  I used logic to figure it out.  After all, a computer is ALWAYS going to determine a result based on real logic.
