Since 2007 a handful more of sea ice observing satellites has been launched into orbit, hundreds if not thousands papers about sea ice have been published and sea ice models have been improved significantly - all telling the same thing: sea ice decline is happening.
It's a good thing science makes progress every day, just start listening.
- casefields 7y agoThe NASA scientist that made those erroneous predictions in OPs post: https://www.nasa.gov/feature/goddard/nasa-study-mass-gains-of-antarctic-ice-sheet-greater-than-losses https://www.nasa.gov/feature/goddard/nasa-study-mass-gains-o... Whoops.
- jf22 7y agoAntarctic ice sheets and arctic ice sheets are on different ends of the planet. This article actually confirms the loss of arctic ice sheets because water levels are still rising despite gains in antarctic ice.
- aldoushuxley001 7y agoWeird cause all the models I’ve seen show basically a balance and no real change. Arctic losing more ice but Antarctica adding more sea ice such that it’s basically a wash.
- soperj 7y agoIt's funny that you pick 2007. This is from Nsidc --> http://nsidc.org/arcticseaicenews/files/1999/10/Sep_monthly_extents13yr.png http://nsidc.org/arcticseaicenews/files/1999/10/Sep_monthly_... It's been flat since 2007 in the arctic. Sea Ice in the Antarctic has actually had a record high in that time period.
- acqq 7y agoIf observing just the plot of "each September in each year" one still misses the whole picture which is (all extents through the time, not only Septembers: http://nsidc.org/arcticseaicenews/files/1999/10/Figure3.png http://nsidc.org/arcticseaicenews/files/1999/10/Figure3.png Specifically, 2012 was such an extreme year that the following years seldom compete with it, but they still do, and the trend to decrease is still obvious.
- soperj 7y ago2012 is an outlier, and the data should just be discarded. The only reason it was as low as it was because a massive cyclone came through in August. https://en.wikipedia.org/wiki/Great_Arctic_Cyclone_of_2012 https://en.wikipedia.org/wiki/Great_Arctic_Cyclone_of_2012
- noiv 7y ago2012 wasn't bad measurement, it was actually visible from space. Also, cyclones in the Arctic is nothing special, 2012 was hefty, because the ice was already very thin and the ocean absorbed a lot of heat.
- soperj 7y agoI didn't say it was. I said it was an outlier. Cyclones in the summer are rare. It was also a major reason that the sea ice extent got as low as it did, and it's never got even close to that low again. It's not relevant to the long term or short term trend.
- acqq 7y ago> it's never got even close to that low again. Actually, in 2019 and 2020 at more dates the sea extent was under that of the same dates in 2012, except for the extreme points in September: 2020: https://nsidc.org/data/seaice_index/images/daily_images/N_iqr_timeseries.png https://nsidc.org/data/seaice_index/images/daily_images/N_iq... 2019: see July: http://nsidc.org/arcticseaicenews/files/1999/10/Figure3.png http://nsidc.org/arcticseaicenews/files/1999/10/Figure3.png
- soperj 7y agoThe storm hit in August. You're ignoring the point, and just being pedantic.
