Antarctic ice has been reaching record extents in recent years


Antarctic ice has been reaching record extents in recent years.

“The narrative from activist ice watchers is along these lines:  2017 minimum is not especially low, but it is very thin. They are basing that notion on PIOMAS, a model-based estimate of ice volumes, combining extents with estimated thickness.  That technology is not mature, and in any case refers to the satellite era baseline, which began in 1979.

The formation of ice this year does not appear thin, since it is concentrated in the central Arctic.  For example, Consider how Laptev and East Siberian seas together added 180k km2 in the just the last ten days.”

Whether there is more or less ice one year to the next is irrelevant to understanding the climate.

All of the temperature data sets, even those upon which climate campaigners appear to have put their thumbs on the scale, record very small temperature fluctuations. 

There has not been enough temperature change under anyone’s measurement to cause major changes to the conditions we experience today.
