Giant Glaciers Melting Past the Point of No Return


You’ve probably heard the recent news that the ice sheets covering Greenland and Antarctica are melting at an even faster rate than previously suspected.

To get an idea of the gravity of the situation you need to understand this: in some places, the ice sheets that cover Antarctica and Greenland are more than two miles thick in places and cover 5.4 million square miles total. They are so massive that gravitational attraction pulls the ocean toward THEM.

When most people think about the melting ice sheets, they think about the rising sea levels, and that’s a big deal, but it’s also important to remember that if the gravitational pull keeping the water around Antarctica is weakened that water will be displaced, making the rising sea levels even worse. When all is said and done, the US will experience a little more sea level rise than other locations based on the displacement.

Melting GlaciersCurrent research notes that the ice is melting from below, and this is problematic since it means the glaciers will lose their moorings. So, not only is three meters of sea level rise already on its way and unstoppable, massive ice sheets large enough to affect gravitational pull may one day float freely.

It’s tragic we have reached this irreversible point. In coming centuries, even more land will be covered by water and more of nature will be destroyed. A full melt would cause sea level to rise 215 feet.

However, optimist that I am, I found one of the most interesting items about this information to be who first reported it, Dr. Richard Alley, a glaciologist, registered Republican, and host of the PBS program Earth: The Operators’ Manual. Maybe now we can get to a point in the US where we start taking action on climate change REGARDLESS of political party.

  1. beepee well, as far as oil drilling goes, the deepest well in existence is “just” 7.7 miles deep. which is only just into the fringes of the upper mantle. Still plenty of way to go before we can screw up the core. On the other hand, fracking wells have been linked with increased seismic activity, and they’re only about a mile deep.

  2. What’s always
    been interesting to me, because of the earth’s proximity to the sun, is that only on earth does water exist in all
    of its states or forms (ground, surface, ice, vapors, steams and clouds), and
    that figuratively, the volume of water has not changed, within the earth’s
    atmosphere since the beginning of time.The earth’s core, however, is another story.By extracting millions of barrels of oil
    p/day, and literally burning it off into the earth’s atmosphere, we contribute to the law of “diminishing” returns. 
    being a scientist I can only imagine, that in terms of the sheer weight of the oil (if
    nothing else), the impact upon the earth’s core and eventually the earth’s crust
    (i.e. worldwide sink holes or ring of fire activity) and subsequently the ice/water ratio.

  3. We have to take action before its too late.
    Chemonuclear Fusion is a
    type of low energy nuclear fusion that has been tested in two
    Aneutronic nuclear fusion can provide unlimited
    electric power without polluting the environment with radioactive
    waste and greenhouse emissions. Chemonuclear processes in small dense
    white dwarf stars
    accelerate the rate of
    nuclear fusion and cause them to explode in spectacular supernova
    The mission of the Chemonuclear Fusion Project is
    to raise awareness of this new and vitally important source of
    environmentally clean energy and to promote research and
    The Chemonuclear Fusion Project is soliciting
    volunteers to help our crowdfunding and educational campaigns. Our
    crowdfunding webpages will soon be up and running. We want people to
    post to discussion groups and help us get the word out that
    aneutronic chemonuclear fusion might be the radiation free way to
    power the world if we can get the funding to build and test
    Artists can help us design T-shirts, mugs, and
    promotional items to sell and give away to our contributors. Writers
    to write promotional materials and post to web forums are also
    wanted. Video producers and professional and amateur scientists who
    can help the public understand the concepts of chemonuclear fusion
    are encouraged to contact us also.
