    So if you poke around on the DMI website, you could counter my point with their data .... except .. notice how the graphic view (February) stops in 2009 (no updates in 10 years?) .. then you can look at the similar NASA graphic ,,.. and looks fairly downward trending on the two months shown (Sep, Mar) , ... except it starts to turn around at about 2009 .... hmmmm. Sure would be interesting to see the same graphic for january with all the data available.

    The animation based on satellite data. it stops in 2009.

    /I think we have "satellite history" of the ice in the area dating back to about 1978.
    // also of note: .. the area of the "Northwest Passage" can be seen in same satellite graphic animations. This is the route that was supposed to open up and be a boon to shipping commerce. That's been the dream since 1848 when the HMS Terror (is that a good name for an exploration vessel?) met it's demise in the ice . -- So far, no boon. Maybe that will change. Maybe it won't.

    I'm not disputing that glaciers have been melting , .... for thousands of years (and sometimes growing). It's the cause that I question.

    I think (don't know, just think ... think) there's a possibility that we are headed back into another mini-ice age... which would be bad news.

    /Glacier National Park is awesome, .. I'd like to go back and see it again sometime.

    We KNOW why climate change is happening. We will not be having an ice age anytime soon.

    Until Florida is underwater. There will be no change or the large scale belief that ice is melting.

    4 and 5 years ago:
    https://www.ec.gc.ca/eau-water/01AD...1E890F8F56/GL-Winter2014-15_FINAL_updated.pdf
    By the end of February, the maximum extent of ice cover was 88.8%, which was the first time since the late 1970s that Great Lakes ice cover has topped 80%in consecutive years (last year’s maximum extent was 92.5%).

    Last year:

    A Polar Vortex Visit Is Bringing Winter Weather That May Feel Like The Coldest Ever

    The breakdown of the polar vortex is the result of climate change.

    The warming climate is melting the Arctic ice. This weakens the jet stream, and it gets wobbly. And this results in the cold Arctic air "spilling" out into more southern areas than usual.

    It seems to be linked to reduced arctic ice coverage. So climate changes that would reduce ice coverage (including but not limited to Milankovitch cycles) would probably contribute to and weakened polar vortex and colder temperatures.

    It is not the Milankovitch cycles.



    Climate scientists know what they are talking about. If you think you know better than they do - PUBLISH!

    Hold on there partner, ... I gotta read all these guys stuff first --

    ----------------------
    These scientists have said that it is not possible to project global climate accurately enough to justify the ranges projected for temperature and sea-level rise over the 21st century. They may not conclude specifically that the current IPCC projections are either too high or too low, but that the projections are likely to be inaccurate due to inadequacies of current global climate modeling.



    These scientists have said that the observed warming is more likely to be attributable to natural causes than to human activities. Their views on climate change are usually described in more detail in their biographical articles.

    These scientists have said that no principal cause can be ascribed to the observed rising temperatures, whether man-made or natural.

    These scientists have said that projected rising temperatures will be of little impact or a net positive for society or the environment.

    These scientists published material indicating their opposition to the mainstream scientific assessment of global warming prior to their deaths.

    Plus, if it DOES warm up and the oceans rise, .. I guess that'll just mean more beach time. .. and that gets me excited.

    How is a botanist's opinion on global climate modelling relevant to the discussion?

    ... Or Al Gore's, .. for that matter.

    --------------------------
    "The Washington Post reproduced Mr. Gore's Harvard transcript as well as his grades and scores at the elite St. Albans high school and later at Vanderbilt University's divinity and law schools. In a word, the transcripts reveal that Mr. Gore's post-secondary academic performance was rather dismal, particularly in the field of science."

    Nobody is talking about Al Gore here. How is a botanist's opinion on global climate modelling relevant to the discussion?
