    Despite Pandemic, Many Europeans Still See Climate Change as Greatest Threat to Their Countries

    In terms of relative rankings, climate change outpaces or ties infectious disease as the most frequently mentioned “major threat” in eight of 14 countries polled, including seven of the nine European countries surveyed. Amid the coronavirus pandemic, five countries, including the United States, name the spread of disease as the foremost threat. People in two countries, Australia and Denmark, put cyberattacks as the preeminent threat.

    Mariners have long recognized and noted in their log books, sea state. The Orca are angry they have no senators or congress persons in Washington, to represent the Sea State. Their group is called Orcastrated Resistance..

    Well no wonder they're mad!
    They should resist orcastration by all means!

    Re post #496:
    ‘‘ . . . never seen or heard of attacks . . . scientists baffled . . . ’’

    The world is in danger when any of the conclusions coming from such unknowledgeable scientific demagogues is taken seriously.

    It's an example of the severe lack of basic knowledge and also of not having even the slightest historical consciousness, which however is all considered to be science by the general public, and by the self proclaimed peer to peer reviewing scientists themselves.

    See for some basic knowledge and some historical consciousness in this regard the below linked thread, which Hoyt already referred to here in post #497.

    It seems like, once one thinks of themself as a scientist, not having heard of something in the science world becomes proof that it either doesn't exist or is pseudoscience.

    On what do you base your opinion?

    Ice shelves propping up two major Antarctic glaciers are breaking up and it could have major consequences for sea level rise

    The Pine Island and Thwaites glaciers, which sit side by side in West Antarctica on the Amundsen Sea, are sustaining rapid damage at the glaciers' shear margins -- areas at the edges of the floating ice shelf where the fast moving ice meets the slower moving ice or rock underneath.

    The two glaciers effectively act as arteries connecting the West Antarctic ice sheet to the ocean. At their base are permanent floating ice shelves that act as a buttress to the fast-flowing ice behind it."Typically the ice shelf acts like slow traffic. It's floating on the ocean but it buttresses the ice traffic behind it," Lhermitte said. "So if you weaken this slow car, then the ice discharges more rapidly."That's exactly what the researchers observed -- and they believe these severely weakening parts of the glacier will accelerate mass ice loss. The study makes the case that this process should be included in models that project sea level rise, which it's not currently a part of.

    The study was published in the Proceedings of the National Academy of Sciences.

    Four decades of Antarctic Ice Sheet mass balance from 1979–2017 https://www.pnas.org/content/116/4/1095
    According to the above paper, "The contribution to sea-level rise from Antarctica averaged 3.6 ± 0.5 mm per decade with a cumulative 14.0 ± 2.0 mm since 1979"
    Sea Level | Vital Signs – Climate Change: Vital Signs of the Planet https://climate.nasa.gov/vital-signs/sea-level/
    According to NASA, sea level rise has been at a rate of change of "3.3
    millimeters per year"

    Antarctica seems to be contributing just over ten percent to sea level rise. The two cited factors in sea level rise are melting ice sheets and expanding warming seawater.

    I haven't looked at Greenland's contribution, but I'm thinking it isn't greater than 50%. So, I am suspicious that much of the driver to sea level rise is human displacement. We are filling the oceans with boats and floating docks and even building islands to increase real estate. I also suspect that a lot more sinking of land around the oceans is going on. As new land mass builds up, whether through natural volcanic eruptions, or adding huge skyscrapers to a shoreline, the weight of building mass upon the Earth's crust causes it to sink.
    In one of my Physics classes, we did a calculation on mountain mass that demonstrated pretty unequivocally, that mountains have a root that, due to their weight, extends down below the mean level of crust into the magma below.

    Since the ocean is rising, in part due to warm water expansion, I wonder if there is data that shows the average Earth diameter is increasing.

    Because the Earth has mass, the Earth has gravity. Because the Earth has gravity, the Earth attracts cosmic dust. Because the cosmic dust has mass, the Earth is increasing in mass. Because the Earth is increasing in mass, the Earth attracts more and more cosmic dust. Where does it all end?
