Climate Change, the Real
(retired, Chevron), Moraga,
It's not talked about, but all
evidence to date of " Climate Change " is that it's particularly a N.
Hemisphere phenomenon. The N. Hemisphere is warming and Arctic ice is
rapidly melting. However, this is in stark contrast to the S. Hemisphere
where there is little evidence of warming nor Antarctic ice melt. This has
puzzled climate scientists, since there is just as much "Greenhouse Gas" in
both Hemispheres! Unfortunately for all of us, this puzzlement is because
they are overlooking the real explanation for climate change. One that's
logical, readily understood, undeniable and importantly quantifiable. Yes,
you have a choice, and here's the 2 minute explanation of what the other
one, the real explanation, is.
For almost two hundred years it has been known that
there is an atmospheric phenomenon described as an Urban Heat Island, or "
UHI" . It describes the fact that urban areas are warmer than their
surrounding rural areas. It simply means that the creation of any urban area
results in atmospheric warming. Its cause is the replacement of all
vegetation, which through evaporative cooling are natural air conditioners,
with stone, brick concrete and asphalt, which are simply man-made, natural
radiators. For the atmosphere, it has the identical result of you turning
off your home air conditioner and switching on its furnace. The air gets
And for the last 130
years we have been creating and growing UHI's all over the globe. Today, if
you put them all together it would be at least a 1.5 million square mile
A UHI so large it would take almost three hours to fly over it. An
artificial desert half the size of the Sahara. In the process, we've
eliminated at least 1.5 million square miles of natural air conditioning.
And unfortunately replaced it with 1.5 million square miles of small, large
and sometimes enormous brick, stone, glass and concrete monoliths surrounded
by more concrete and asphalt. All man-made radiators. It's a recipe for a
thermal disaster and we're seeing it. It's an accepted fact that New York
has its own climate, so too does London, Paris, Tokyo, Delhi, Manila, Mexico
City, Seoul, and Sao Paolo. They all have their own climate. The list is
endless. And, unfortunately we can now add Beijing, Shanghai, Guanghzou,
Wuhan and other enormous Chinese cities to that list. Brand new cities that
didn't show up on the radar 20-30 years ago. All cities are UHI's, it's an
indisputable fact. And the more we build and expand them, the warmer the
atmosphere will get. That's the definition of UHI. As a result, today, we
are evaporating less water and capturing more solar energy than any time in
And if we
apply process engineering 101 fundamentals, we can quantify the
consequences. Less vegetation, equates to less evaporation. Compared to 130
years ago, we're evaporating at least 2.9 billion acre/ft less water
annually. Consequently there's 2.9 billion acre/ft less rainfall annually.
Since 2010, enough water to fill the 5 Great Lakes. It has resulted in
historic N. Hemisphere summer droughts and has devastated forests.
Less evaporation equates to less evaporative cooling,
and it's enormous cooling. The loss of 2.9 billion acre/ft evaporative
cooling annually means the atmosphere circulating today, compared to 1890,
has the potential to melt a 1.5 million square mile block of ice 21 ft tall,
annually. And, that's not all. Add to that the sensible heat gain resulting
from the replacement of the vegetation with man-made radiators, the
horizontal concrete and asphalt ones, together with the massive vertical
ones. And that's conservatively another 3 ft of annual ice melt. In total it
means that, compared to 1890, the global UHI we've created results in the
atmosphere circulating today with enough retained heat to potentially melt a
1.5 million square mile block of ice 24 ft tall, annually!
What happens next? Letís combine that with another
atmospheric phenomenon described as the Coriolis effect. In each hemisphere,
the atmosphere is essentially contained, it circulates within it. The
atmosphere in the N. Hemisphere circulates in the N. Hemisphere, and the
atmosphere in the S. Hemisphere circulates in the S. Hemisphere. The
circulation pattern in both hemispheres is from the equator to the poles.
Since 90% of that enormous, global, 1.5 million square UHI is in the
N.Hemisphere, 90% of the potential ice melt is in the Arctic. And it means
that just in the last 10 years, enough heat has been circulating in the N.
Hemisphere compared to 1890, to potentially melt a mountain of ice 430 ft
tall the size of Greenland!! In the S. Hemisphere the story is much
different. With only 10% of the global urban development, there is little
warming and little evidence of Antarctic ice melt. There is less rainfall
too, but it's only reduced by one tenth as much as the N. Hemisphere.
However in Australia, which has little rainfall anyway, any less rainfall
has serious consequences
That's it. The 2 minute summary. In 2 minutes I've explained not only why
nearly all the disappearing ice is in the Arctic, I've quantified it. I've
also explained why some parts of Europe are experiencing historic droughts.
Finally I should add that from 1940 through 1974, we were not building new
cities, but destroying old ones and then rebuilding them. Which is why
atmospheric temperatures didn't rise in that period. Another fact which has
puzzled the climate scientists.
That's it. No smoke, no mirrors, just indisputable
facts. The undeniable, irrefutable, UHI, explanation for "Climate Change".
And the remedy. Evaporate more water, plant trees.
Billions and billions of them. Within 30-40 years, the temperatures will
fall, the droughts will end Arctic ice will return, and forest fires will
diminish. It may have taken 130 years to get here. But it takes a lot less
time to rectify it, because we have the knowledge and tools to fix it
you have a choice, one explanation that no one can understand and is refuted
by the evidence. Or one that everyone can understand and is supported by the
