then warmed more than at any earlier time of instrumental observations. If the mean temperature in Iceland could rise by almost 1.5°C in ten years (1920 to 1930), a similar drop in the temperature in the late middle ages was surely reasonable?
The climatic research community soon became aware of the unusual situation. Before 1940 this temperature rise seemed attributable to an anthropic increase

uplift and subsidence into account, and
assuming global sea-level rise of about 1 m towards the end of the century, the
relative sea-level change will range from a 40–60 cm rise in subsidence regions
to 10–180 cm sea-level drop-in regions of fast uplift. There is considerable
uncertainty in these estimates, with easily justifiable revisions of additional
25–40 cm of sea-level rise. However

seismic moment has been replaced by 101.5M+9.1. When g = 0.5 the form R = r + K·C(M) gives
equivalent results to the form R = r + k·10g·M when fitted to the data – the only difference
