volcano because just one small eruption is millions of times larger in volume of CO than the entire world production of hydrocarbon fuels...

I'm going to need a source here, because https://www.skepticalscience.com/volcanoes-and-global-warming.htm says that volcanoes produce about one percent of the world's CO2 emissions.

Until Khan and these other shareducators get the ability to issue actual degrees, this won't matter that much. In many career jobs, you have to have a degree. Just knowing your stuff will only get you so far. (Also, it is easy for HR to see if you have a degree or not. It is hard for them to know if you are any good, but no-one has ever been fired for hiring some-one with a degree. So HR departments will prefer to require degrees.)

Often statistics are used as a drunken man uses lampposts -- for support rather than illumination.
