It misses a most important point: when people talk about a "global warming hiatus" from 1998 to 20XX, they are always full of shit.
1998 was an abnormally warm year. When people say things like "The last N years were N of the N+1 warmest on record", 1998 is always that +1. The trend-line for global warming only just now started to creep above 1998; it was like 2 or 3 standard deviations above the average.
If you start your trend lines at 1998, they always look flat, because you are starting at an outlier. If you take a trend line over a different period - for instance, 1990 to 2010 - the "global warming hiatus" goes away and the data looks like a normal noisy data series conforming reasonably to a linear trend.
If you see someone talking about climate data over a period of time starting at 1998, they are full of shit. They are using one of the most obvious and well-known lies-told-with-statistics you'll ever come across.
