Dr Igor Polyakov (University of Alaska) for the period 1860-2005.

These latest findings appear to contradict the general perception that sea level rise is escalating at present.
This data set shows clearly that the Arctic was at its warmest in 1935 and 1936 and the present temperature in the Arctic is about the same as it was in the mid-1930s. Further, the Arctic witnessed significant icecap and glacier melting during the 1920s and 1930s as evidenced by the following commentary “The Arctic sea is warming up, icebergs are growing scarcer, great masses of ice have been replaced by moraines of earth and stones, at many points well-known glaciers have entirely disappeared (US Weather Bureau CIRCA 1922)”.Study finds no acceleration in sea level rise, but instead a small average deceleration of -0.0014 and -0.0123 mm/yr2. These latest findings appear to contradict the general perception that sea level rise is escalating at present.(Houston & Dean (Journal of Coastal Research 2011)
