Yes. I disagree, and so do the scientists who did the work (see below) Note the last sentence of the abstract, where they say:"We find that the glacier contribution to sea level rise was 5.5±1.0 cm during the period 1850-2000 and 4.5±0.7 cm during the period 1900-2000." Doing the subtractions, from 1850-1900 glaciers contributed a 1 cm rise in sea level (or a rate of 2 cm per century). whereas from 1900-2000 they contributed a 4.5 cm level rise, MORE THAN TWICE AS FAST. No way you can have the same slope over the course of 1850-2000 with that difference. Further if you look at that really badly-done graphic of the "OISM", you can see glacier length essentially noodling around the same range from 1700 to about 1850-1870, and only starting a sustainedclimb after around 1850 to 1870, which is when hydrocarbon use started taking off. Further, as the abstract show, that climb was much steeper after 1900. And by all accounts of glaciologists, that climb has been steeper yet since the last decades of the 20th century. So, wherever Willie Soon is getting, or inventing his data, it's bunk.

Abstract. We present a method to estimate the glacier contribution to sea-level rise from glacier length records. These records form the only direct evidence of glacier changes prior to 1946, when the first systematic mass-balance observations began. A globally representative length signal is calculated from 197 length records from all continents by normalisation and averaging of 14 different regions. Next, the resulting signal is calibrated with mass-balance observations for the period 1961-2000. We find that the glacier contribution to sea level rise was 5.5±1.0 cm during the period 1850-2000 and 4.5±0.7 cm during the period 1900-2000.
