Daily sea ice Area losses have been above 100k for 4 days in a row.
Total Area has been lowest in the satellite record for 7 days in a row.
Can't just be the sensors getting fooled, especially as the data is 5 day trailing average, which tends to smooth out oddities.
Total Extent has been lowest in the satellite record for 23 days in a row.
No matter what the final outcome, that's quite a bit of the unused part of the graph paper with a big fat line on it.
Below is a good example of why NSIDC was reluctant to produce daily extent (& area) daily change data for general consumption. Too erratic..
