text: Again, the recent era on the right side of the picture has no chance to compete with the late 17th and early 18th century: the 1960-2009 period with the +2.65 C per century ends up outside the top ten. The winner is 1688-1737 with the trend +3.83 C per century. The fastest cooling was in 1722-1771, by -1.69 C per century. These 50-year trends can??t quite be extrapolated to a century, either. But they??re much closer to that than the 10-year or 15-year trends.
