Climate Hysteria Ramps Up in Antarctica but Recent Data Shows Sea Ice Levels Similar to 1966

The climate catastrophe caravan is on the move again with the alarmists whipping up fears over a supposed low rate of winter sea ice in Antarctica. In the Financial Times, science editor Clive Cookson reports that Antarctica “faces a catastrophic cascade of extreme environmental events… that will affect climate around the world”. Needless to say, there is no mention that Antarctica sea ice was at a record high in 2014, but curiously missing from all the hysteria is the fact that reanalysed early satellite data shows similar levels of winter ice in 1966. Even more curious is that minimal journalist sleuthing is required to uncover this information, since it is supplied by the frequently-consulted National Snow and Ice Data Centre (NSIDC).

Colorado-based NSIDC cited evidence that early Nimbus satellite data revealed winter sea ice extent of around 15 million square kilometres in 1966 “may have rivalled the very low level seen today”. There are some uncertainties in reanalysing such early satellite data, but the NSIDC says the findings are consistent with observations that Antarctica sea ice extent is “highly variable”. Last year, a group of American geographers and statisticians examined historical observations of Antarctica sea ice extent and found “statistically significant” positive trends since 1979. Furthermore, these trends across all four seasons compared with “statistically significant decreases” throughout much of the early and middle 20th Century.

Some of the FT guff came from a report commissioned by the Net Zero-promoting U.K. Government. Lead author Professor Martin Siegert from the University of Exeter says he is “staggered by the amount of change we’ve seen already in the past few years”. In fact we only have complete records of Antarctica sea ice since 1979, but it is more than likely that, like ice in the Arctic, it waxes and wanes on a natural cyclical basis. But like the coral on the Great Barrier Reef, the politically-inspired alarmists cry wolf when it falls, but move on to the next cherry pick when it recovers. Even though carbon dioxide is well mixed over the entire southern hemisphere, the small contribution made by humans is somehow held responsible, while cyclical changes offer the opportunity for Greta Thunberg-style contributions to climate science knowledge.

If Antarctica, which is considerably colder than the Arctic, began to freeze over when the average global temperature was about 6° C higher than now, how can a 2° C rise in temperature melt it? (Patrick Moore).
