Maybe Our Republican candidates will hear about all of the Uproar...and get a clue!
I know for a fact that the CFC known as R-12, the primary existing refrigerant before some professor at UC California Irvine got a Noble prize for saying that CFCs were destroying the upper atmosphere ozone layer, weighs more than air... about six times more than air. That means that R-12 released into the atmosphere drops like a rock.
Shipyard workers need to know this because refrigerants released inside a ships hull would push out - replace - air held inside the hull and kill anyone not equipped with breathing apparatus.
This guy calls himself a mathematician? He is either incompetent or lying. When fitting a straight line to data the most common approach is to use a least-squared-error method. When using this algorithm over even a modest number of data points the value of any one (eg. the starting point) makes little difference - there is no particular significance to that value over the second, third, nth...
My take, lying POS. Counting on most people not being familiar with math, and their eyes glazing over when they hear one of the anointed speak... Well, I don't buy it, the Emperor has no clothes.
Thanks for reminding me how irritating I find this ‘bad astronomy’ guy. He seems like an arrogant twerp to me.
