1 Introduction
Arctic sea ice extent over the modern satellite record (1979–present) shows downward trends in all months, smallest in winter and largest at the end of the summer

The modern satellite record for the Arctic began in 1971, not 1979. Nimbus satellites showed a sharp increase in ice extent from 1974 to 1979. which NSIDC doesn’t like to discuss because it would completely mess up their linear graph below.

Below is the incline which NSIDC is hiding. From the 1990 IPCC report.

    I’m not sure why the record would have started in 1971, since there weren’t any Nimbus launches that year. They even have data from Nimbus 2 which was launched in 1966.

    I seem to recall that we had very thick ice up in Eureka that winter/spring. I have a photo of the auger extensions i used to drill down to measure the thickness…and from our station records one of the thickest years recorded…

  3. Andy DC says:

    The 1979 start date is the very definition of cherry picking.

      No, its the very definition of lying.

    • Dr. Stroeve says:

      no it’s the start of the multi-channel passive microwave record. Steve knows that ESMR was a single channel passive microwave sensor and it does not extend to the time that SMMR was launched. So if you want a record from 1972-present, you have to fill in the gap with other data. The ‘modern’ satellite data record does indeed begin in October 1978 (or for September from 1979 to present).

      Steve is also aware that there are other satellite observations that extend to the early 1960s. Most of this is visible imagery, which is also useful for getting information on where the ice is as long as it’s not cloudy. Then there are ship observations, aircraft observations, etc. that can allow one to go back to 1953 somewhat reliably. Steve could show that data, but he selectively chooses not to since it would invalidate the point he hopes to make.

    I posted this on a different thread, should have posted here since it is about the 1973 chart.

    OK, here is my attempt. You will have clicked on different spots than I did, but this is the data I extracted using EnGauge (a chart digitizer) :

    Download the sea ice excel sheet…
    Looks reasonably close. Need a better original to have a better result.
