4 thoughts on “Sea Ice Extent (Global Antarctic and Arctic) – Day 82 – 2016”
Antarctic and global sea ice extent is growing at the fastest rate in the past ~12 days than ever before with the possible exception of 2015. In the grand scheme of things it’s probably meaningless but it leads me to another point:
I had an argument today with a climate change alarmist on another website who tried to tell me that baseline variations (e.g. 1950-1981, 1960-1991, 1981-2010, etc.) were not evidence that scientists studying global warming are trying to emphasize the warming trend conclusions in their papers. He then went on to give a 20th c. average per century (0,7852°C) and gave examples of exact trends between 5-, 10-, and 20-year constructs. I pointed out that none of those are climatologically significant or accurate and could just as easily point out downward trends showing global cooling if employing such short time frames.
Not surprisingly, I got no response.
Having said all that, it is reassuring to see Antarctic extent grow as quickly as it is considering the SH is still in their autumn and solar angular insolation is far from its minimum. More ice now means more ice later – presumably – and higher albedo come next spring in the southern hemisphere.
Landscheidt.info is showing something very interesting at this point in SC24 – that of extremely low F10.7 flux and an unprecedented divergence between northern and southern solar polar field strengths. Could this be the start of a Grand Minimum?

I’m not worrying about Antarctica. The long term trend is 2 or 3 years up and then 1 down. Sort of a long term zig zag with a trend of up.
Are you worrying at all about the Arctic then?
Not really. Satellite data is only from 1979 and therefore we are only 37 years into what is probably a 66 year cycle.
