    Temperatures change, water when it gets cold becomes ice. When it warms up after winter that ice melts.
    The April 2018 issue of Scientific American had an article on 'The Arctic Meltdown", as I mentioned, and I suggested you should read it, since you at least claim to be a citizen of Canada. One would think you would be interested enough to inform yourself. One would think. Here are a few brief excerpts----it would do no good to link, as you would run into an immediate paywall. [I will be getting my OWN subscription here in about three months, and then I THINK I will be able to link to articles from Sci Am.]

    "The Arctic climate is changing rapidly, breaking at least a dozen major records in the past three years. Sea ice is disappearing, air temperatures are soaring, permafrost is thawing and glaciers are melting The swift warming is altering the jet stream and polar vortex, prolonging heat waves, droughts, deep freezes and heavy rains worldwide."

    "The last time the Arctic was only slightly warmer than today---about 125,000 years ago---oceans were 13 to 20 feet higher. Goodbye Miami, New Orleans, the naval base in Norfolk, Virginia, most of New York City and Silicon Valley, as well as Venice, London and Shanghai. New research suggests that rapid Arctic warming also tends to reroute the jet stream in ways that could allow punishing weather patterns to linger across North America, central Europe and Asia longer than usual, subjecting millions of people to unyielding heat waves, droughts or relentless storms. Plankton are increasing throughout the southern Arctic Ocean, which may disrupt food chains that support commercial fisheries. And the massive ice melt is adding to an enormous blob of freshwater south of Greenland that may be slowing the Gulf Stream, which could significantly change weather patterns for continents on both sides of the Atlantic Ocean."

    Much, much more in the article, of course. Which you should read.

    Didn't I already mention that?

    Yes, and this is all pointless conjecture. The best and most accurate models in the world can only predict the weather to a meaningful degree about 2 weeks out.

    Cataclysm can happen at any point, blaming an asteroid on humans is kinda pointless.

    At the end of the day, co2 is a minor warming influence on climate. Dwarfed by the effect of water vapour and cloud cover.

    Cloud cover is partially related to solar and even interstellar activity, moon position relative to the sun and earth, etc...

    Wow. After all your posts on this subject, you finally reveal that you don't understand the difference between weather and climate, which is usually covered-----at least in America-----in an 8th grade Earth Science course.

    You somehow REALLY missed out on a BIG BIG chunk of your science education.

    And this is NOT conjecture. These are MEASURED OBSERVATIONS. Sheesh.
    Thanks from RNG
