Did global warming stop in 1998?

The official thermometers at the U.S. National Climate Data Center show a slight global cooling trend over the last seven years, from 1998 to 2005.
Actually, global warming is likely to continue—but the interruption of the recent strong warming trend sharply undercuts the argument that our global warming is an urgent, man-made emergency. The seven-year decline makes our warming look much more like the moderate, erratic warming to be expected when the planet naturally shifts from a Little Ice Age (1300-1850 AD) to a centuries-long warm phase like the Medieval Warming (950-1300 AD) or the Roman Warming (200 BC- 600 AD).
