Growth In Sea Ice Over The Past 90 Years

Posted on August 4, 2014 by Tony Heller

In 1922, you could sail north of 81N in ice-free water

This year you couldn’t make it to 80N in ice-free water

There was no sea ice on the North Coast of Spitsbergen in 1922, even during winter. This year that region is still frozen over.

Experts say that the Arctic is disappearing due to CO2, because they are completely incompetent and have no idea what they are talking about.

    Arctic sea ice melt is unprecedented (in the satellite era). 🙂

    Abstract
    The Early Twentieth-Century Warming in the Arctic—A Possible Mechanism

    The huge warming of the Arctic that started in the early 1920s and lasted for almost two decades is one of the most spectacular climate events of the twentieth century. During the peak period 1930–40, the annually averaged temperature anomaly for the area 60°–90°N amounted to some 1.7°C…..

    Abstract
    The regime shift of the 1920s and 1930s in the North Atlantic

    During the 1920s and 1930s, there was a dramatic warming of the northern North Atlantic Ocean. Warmer-than-normal sea temperatures, reduced sea ice conditions and enhanced Atlantic inflow in northern regions continued through to the 1950s and 1960s, with the timing of the decline to colder temperatures varying with location. Ecosystem changes associated with the warm period included a general northward movement of fish……

    Abstract
    Early 20th century Arctic warming in upper-air data
    Between around 1915 and 1945, Arctic surface air temperatures increased by about 1.8°C. Understanding this rapid warming, its possible feedbacks and underlying causes, is vital in order to better asses the current and future climate changes in the Arctic.

    IPCC – AR4
    Average arctic temperatures increased at almost twice the global average rate in the past 100 years. Arctic temperatures have high decadal variability, and a warm period was also observed from 1925 to 1945.

    “Arctic Warming” During 1920-40:
    A Brief Review of Old Russian Publications
    Sergey V. Pisarev
    1. The idea of Arctic Warming during 1920–40 is supported in Russian publications by the following facts: *retreating of glaciers, melting of sea islands, and retreat of permafrost* decrease of sea ice amounts…..

    Abstract
    …..Winter season stable isotope data from ice core records that reach more than 1400 years back in time suggest that the warm period that began in the 1920s raised southern Greenland temperatures to the same level as those that prevailed during the warmest intervals of the Medieval Warm Period some 900–1300 years ago. This observation is supported by a southern Greenland ice core borehole temperature inversion……

    There is less ice now than anytime during the 20th century – read the IPCC report!

    What was the Antarctic doing at this time?

    Colder and less snow?

    Everybody knows Arctic history began in 1979…/sarc.

    Of course, that it just happens to coincide with the last maximal ice coverage, is merely coincidental.

    Based on the actions of the rest of the Team, makes one wonder if the media will start ‘adjusting’ their old articles to show every day and every point on earth in the past was a Garden of Eden.

    1922 Alarmism was remarkably the same as today:
    “…the Antarctic icecap is much the more extensive and more massive, and, they hold, it is actually still increasing by evaporation from the immense sea areas of the Southern Hemisphere and condensation over the great ice-covered Antarctic Continent. With ice ever forming above and a sea growing gradually warmer below, the process must eventually overbalance, the undermined glaciers disintegrate, and the icecap break up. Mountain after mountain of ice will fall into the sea, be swept northwards by the currents, and melt, thus bringing about, but at a much more rapid rate, the threatened inundation of the land by the rising of the sea..”

    In 1948, Scientists dreamed of melting Antarctica’s ice sheet and digging it up.
    Now they dream of growing the Antarctic ice sheet to cover the southern hemisphere.
    What a weird mob!
