No. It hasn't paused.
All of those "15 year pause" calculations use the same starting point of 1998.
1998 was a record high temperature year, due to a strong El Niņo. If you shift just 2 years earlier, so use 1996-2010 instead of 1998-2012, the trend is +0.14 C per decade, so slightly greater than the long-term trend. 15 years isn't really long enough to get any meaningful trend.

Look, I'd love to keep refuting your arguments. I probably will continue to do so. But it makes me wonder, just what kind of evidence would you require to be convinced?

That's not a rhetorical question. I really mean it. What evidence would you have to see in order to be convinced climate change is real?
