    I like these new videos Tony, keep them up. Also love the photography. Nice to see someone actually going out seeing things and not l00king at a phone or such.

    I mentioned the Arctic the other day saying 2017 was following 2016 closely and 2012. You can forget 2012 as unusual but 2016 was a very nice “average” year weather wise in the Arctic and it would be nice to have another “average” boring year to compare like to like, even on a short time scale. Will not grab headlines but be interesting.

    However, now read the NSIDC summary
    https://nsidc.org/arcticseaicenews/

    ” On July 2, extent was the same as that recorded in 2012 and 2016. The year 2012 ended up with the lowest September extent in the satellite record.”

    and later

    ” Figure 5 shows that most of the period from July 2016 to July 2017 was extremely mild and was milder (less cold) than both 2006 to 2007 and 2011 to 2012. September of both 2007 and 2012 ended up with very low September sea ice extent.”

    The thing is they are claiming a link to those two 2007/2012 outliers so soon. They cannot do that as far as I can see because 2007 was due to lots of sunny days and warm winds from the south compacting and melting the ice and 2012 was fragmented ice being melted out by stormy conditions and then warmth. Neither usual.

    2017 has been so far usual it seems, like 2016. So why do they bring those years into it ?

    As you know I am more on the viewpoint Arctic ice extent is changing to be a lot lower (why?) than Tony, so these concerns of mine in the reporting are not from someone who is more skeptical.

      As always, the low point will be determined by WEATHER, not climate.

      The current level of Arctic sea ice is higher than it has been for 90-95% of the last 10,000 years. 1979 was the coldest year in over a century, and the sea ice level was at extreme levels, up there with the levels of the Little Ice Age.

      The current dip since the EXTREME level of 1979 is totally in line with the AMO cycle, and probably around the same as in the 1940s, 50s and certainly higher than during and before the MWP.

      Current Artic temperatures are around the same as 1940s, 50s, and cooler than most of the last 10,000 years.

    “So why do they bring those years into it?”

    I have this crazy suspicion … but no, they would not do that, would they?

  4. Andy says:

    The figures re the Greenland Ice Shelf are interesting, but it would be helpful if you could provide a URL so we can inspect them ourselves. Afer all you are inviting us all to be skeptical :)

    we’ve been freezing our butts in Minnesota this “summer” yet all we hear about is the “unprecedented” temperatures of the desert Southwest.

    • Mark Luhman says:

      The summer and winter cold in Minnesota as a native Minnesotan is why I now live Arizona, when for a walk a ten this morning, high 90s, put on about a mile and a half at 12:45 low hundreds, I do like the heat. Late afternoon indoors, sunset and after back out on the screen porch.

    Dear Tony,

    What do you say to those who argue: “well, it’s called climate change and not global warming for a reason. Extreme temperatures will increase in both directions. It is supposed to get warmer in some areas, and colder in others.”

    This argument drives me nuts because it doesn’t make any sense. If you believe in AGW, you should call it global warming because that is what you believe in! Not this wishy washy bullshit of being able to call anything “climate change”. Arg.

    • Michael J Krysak says:

      The only thing constant in this world is change. That man can influence or control climate to any great degree is the absolute height of pride and arrogance.

    The isolated cold nights at a couple of weather stations in New South Wales (including Goulburn) do not mean anything in the greater scheme of things, especially as cold nights are, in fact most likely to occur here when the skies are clear and the days are relatively warm.
    The link below details the June 2017, averages for New South Wales
    http://www.bom.gov.au/climate/current/month/nsw/summary.shtml
    “New South Wales recorded its warmest June mean maximum temperature since 2008
    Maximum temperatures were above average across most of the State, with some parts of central New South Wales including Dubbo and Bathurst experiencing their warmest June days on record
    Minimum temperatures were well above average in the northeast of the State, but well below average in much of the south and west due to clear night skies

    If you scroll down the page you will find pictorial representations of the temperature and rainfall as compared to long term averages.They are helpful in terms of the discussion about the difference between the summer being experienced in Minnesota vs that experienced in the south west.

    The bureau are becoming highly accurate in their forecasting. The one concern I would have is that their averages for each station are based on all available figures- so that if the temperatures are increasing this would be partially obscured by a gradual shift of the average.

    Found this article (thanks, Drudge):
    http://www.news.com.au/technology/science/space/sun-might-plunge-into-deep-solar-minimum-which-could-cause-part-of-earths-atmosphere-to-collapse/news-story/69f270ee0ad403c5f1770f793cf02562

    Check out these two paragraphs:

    “It’s not entirely clear why low solar activity causes our thermosphere to collapse — or what it might be doing to our planet.

    “But when it happened back in 2008-2009, scientists suggested that climate change might be adding to the cooling and contracting in the upper layer of our atmosphere.”

    Can anybody make heads or tails out of this — do I read it right where it says that “climate change” might be ADDING (i.e., contributing) to atmospheric COOLING???

    i believe this supports my theory that CO2 has a net negative feedback, due to asymmetry in the IR-CO2-KE equation.

    Climate scientists have compared the complete relaxation of CO2’s bending states in response to shock excitation to the mean free path length of gas, and concluded the IRCO2 step is rate limiting, hence net warming.

    However, the proper math is a statistical analysis of the simultaneous relaxations and excitations of many CO2 molecules at near equilibrium, with unexcited molecules unable to relax, and excited unable to excite.

    The overal relaxation time is then in the order of pico seconds, shifting the equation to net cooling. hence more CO2 equals hotter summers, but even colder winters. It also explains why we always see high CO2 prior to an ice age.

    CO2 is a negative feedback agent.
