Reflecting on some of Mother Nature’s realities about Basic Earth
Science as a comparison to the man-made global warming AGW Alarmists materials
so prevalent in today’s media.
The AGW Alarmists love to show videos of land-based glaciers
breaking off (calving) and crashing into the water.
A major example is: "CHASING ICE" captures largest
glacier calving ever filmed
No mention that calving is a totally natural process and
happened during the Little Ice Age and is NOT unique to warming; in fact it is
glacier retreat that is related to warming resulting from either the sun above
or volcanoes below or both.
The video byline:
More Proof of Man-made Global Warming!
The dialogue goes on to overlay the calving of an advancing
glacier to the retreating of a stagnant glacier, two very different natural
The old adage applies: things are either growing or they are
It’s interesting that by definition a large mass of ice is labeled
a glacier only if it is moving.
Glaciers move because they are incredibly heavy, they reside
on sloping ground and their weight causes the ice on the bottom to melt into a
layer of water thereby providing lubrication to facilitate the sliding.
This process is called: Regelation – I first saw this
interesting (and counter-intuitive) demonstration in a class in 1956 (yes -- I
am that old).
Most glaciers slide downhill until they meet a body of
water. Typically, there is a significant
cliff at that point. The leading edge of
the glacier cantilevers out over the ledge.
When the weight of the cantilevered portion exceeds the strength of the
ice above the ledge the ice breaks off and the extended ice falls into the
water often with great fanfare.
Many of our current Northern Hemisphere glaciers grew during
the Little Ice Age, following the Medieval Warm Period. The “natural global warming” that ended the
Little Ice Age circa 1750 stopped the growth of most glaciers in the Northern
Hemisphere and caused them to start their melting and retreat.
An excellent documented example is Mendenhall Glacier in Juneau Alaska.
That warming process, that is still going on today, started
well before there was any man-made CO2.
There has been less than one degree warming in the past 250 years and no
significant temperature change in the past 18 years.
Once glacier retreat starts, it typically accelerates
because more snow and ice is not accumulating on top of it and more and more
earth and rocks are exposed around it. Those
materials absorb the sun’s energy, warm-up, and accelerate the melting in
contrast to glacial ice that reflects much of the sun’s energy.
One can observe this process on a winter’s day when a small
bare spot appears on a blacktop surface covered with light snow. Accelerated melting occurs at the bare spot
and it quickly expands outward compared to areas where there is no blacktop exposed.
(Unfortunately many people have never seen snow on a
Everyone should be skeptical of the claims being made about
“man-made” global warming by AGW Alarmists and reflect on the facts that:
natural-global warming: The Only Kind So
The Climate is Changing;
The Climate Has Always Been Changing!
The Arctic Ocean is warming up, icebergs are growing scarcer and in some places
the seals are finding the water too hot, according to a report to the Commerce
Department yesterday from Consulafft, at Bergen, Norway
Reports from fishermen, seal hunters and explorers all point to a radical
change in climate conditions and hitherto unheard-of temperatures in the Arctic
zone. Exploration expeditions report that scarcely any ice has been met
as far north as 81 degrees 29 minutes.
Soundings to a depth of 3,100 meters showed the gulf stream still very
warm. Great masses of ice have been replaced by moraines of earth and
stones, the report continued, while at many points well known glaciers have
Very few seals and no white fish are found in the eastern Arctic, while vast
shoals of herring and smelts which have never before ventured so far north, are
being encountered in the old seal fishing grounds. Within a few years it
is predicted that due to the ice melt the sea will rise and make most coastal
I must apologize; I neglected to mention that this report was
from November 2, 1922, as reported by the AP and published in The Washington
Post - 93 years ago – and article confirmed by Snopes.
Another Little Ice Age:
During the period 1940 to 1974 there was significant cooling
in the Northern Hemisphere. So much so
that “concerned scientists” reached a “consensus”, that earth was entering
another Little Ice Age and many people would face starvation and freezing. This was widely publicized in both NewsWeek
and Time magazines:
