His quibble with the bar graphs there doesn't make a lot of sense given that a Y-axis starting at 0 degrees is just as arbitrary as starting it at 13.4 degrees.

The point was that starting the Y-axis "suitably high" makes it look like the relative differences in the values are greater than they actually are.

In this case, it was done to make "climate change" look like a vastly bigger problem than it actually is.

It wasn't just "his quibble" - it's a very real problem with the way the (actual non-)issue is presented to the masses.
