In newly published papers, scientists have reported that Arctic sea ice extent grew during the decades from the 1940s to the 1980s before declining after the 1980s. The Arctic sea ice trend has thus undergone an oscillation rather than a linear recession, contradicting the models.
Furthermore, the instrumental record indicates that Arctic temperatures have stopped rising since about 2005.
On the other side of the planet, the sea ice surrounding Antarctica has been growing since the 1970s, or for nearly 40 years now. This sea ice expansion coincides with an overall Southern Ocean cooling trend of about -0.3°C per decade since 1979.
No Net Arctic Warming Trend Since The 1930s, 1940s
"In 2017 about 33% of the March maximum was retained, so the melt season losses were considerably less than in the past."
"Earlier observations showed that Arctic ice extents were low in the 1940s, grew thereafter up to a peak in 1977, before declining. That decline was gentle until 1994 which started a decade of multi-year ice loss through the Fram Strait. There was also a major earthquake under the north pole in that period. In any case, the effects and the decline ceased in 2007, 30 years after the previous peak. Now we have a plateau in ice extents, which could be the precursor of a growing phase of the quasi-60 year Arctic ice oscillation."
"The low point just reached is clearly still below the normal value for the 1981-2000 time period, but it is actually a tad higher than the last couple of years (not shown) and safely above the record low seen during 2012 and also above levels seen ten years ago. The Arctic sea ice extent has been generally below-normal since the middle 1990’s at which time the northern Atlantic Ocean switched sea surface temperature phases from cold-to-warm and it is likely to return to pre-mid 1990’s levels when the ocean cycle flips back to cold in coming years. "
The National Snow and Ice Data Center (NSIDC) was forced to admit:
Overall, however, reduced melting and heavy early springtime snowfall may result in a net increase in Greenland’s ice mass this year for the first time this century.
The 2017 melt season has been less intense than recent years, and is below average melting for the 1981-to-2010 reference period. Surface melting has been low in the southeast, and has been limited to coastal regions at low elevations. “
