Some researchers have argued that the higher trends from the satellite measurements proves that there has been an «acceleration» in sea level rise, e.g., Church & White, 2006 (Abstract; Google Scholar access) or Cazenabe & Nerem, 2004 (Abstract; Google Scholar access).

Paper J notes that the anthropogenic effect on sea level rise in one region of the world (the Pacific Ocean) over one period of time (1993 - 2013) is too small to detect at a statistically significant level due to factors such as: a) small sample size (only 20 years), b) the effect of control variables (such as the IPO), c) limitations of satellite altimetry measurement, the technique being used to measure sea level in paper H. Paper K offers a contrasting account of paper J, noting that part of the Pacific sea level rise is anthropogenic.
