Climate Hysteria Ramps Up In Antarctica But Recent Data Shows Sea Ice Levels Similar To 1966 Watts Up With That?

 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.

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.

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.

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.

According to a recent paper, Antarctica sea ice has "Modestly expanded" and warming has been "Nearly non-existent" in this period.
