An Essay Concerning Our Weather

I've been temporarily distracted from my Steele's Climate Horror Stories project by Science of Doom's naive excursion into social/political commentary.  While working on my next post which looks at some of the comments over at SoD I was reminded of an article I wrote for the 1995 November/December issue of the Humanist Magazine which was followed by a slightly edited version Nov/Dec 2005 which I'm reprinting here since I've been wanting to do so for a long time and I'll be referring to it in my next post.

“Katrina and Rita in Context”

Printed in The Humanist,  Nov-Dec, 2005 issue 

There has been something missing from the recent news coverage in the aftermath of 
Hurricanes Katrina's and Rita. No one seems to be reporting on the real story ~ namely the 


These most recent storms should encourage U.S. citizens to recognize that we are facing a 
powerful entity that has only begun to barge into our American way. Look up into that 
beautiful sky overhead and consider its substance, dynamics and might. Our atmosphere is 
the product of more than four billion years of ongoing evolution ~ geological as well as 
biological. It's a tenuous veil of gases that lays upon the surface of our earth, thin as 
the finest silk upon your skin. This veil has a most interesting structure, one that's 
worth thinking about.

Our atmosphere is composed almost totally of nitrogen and oxygen. Interwoven into this 
medium is a gossamer thin admixture of everything else: thousands of different compounds 
that can be grouped into almost two hundred distinct families. Combined, these compounds 
make up less than one percent of our atmosphere's volume. Most of this volume is made up 
of inert compounds and noble gases, so called because they don't react with their 
surroundings very much, if at all. Within this matrix of nonreactive molecules is 
another, yet thinner community of reactive compounds. By volume, these reactive 
components total less than four hundred parts per million. This is where the action is. 
These chemicals are always reacting with each other: they combine, split up, mutate, 
affect neighboring molecules, change characteristics ~ and they do this at nonstop 
hypervelocities. This is the scaffolding over which energy, moisture, and heat perform 
their weather ballet.

What's new is that, over the past two hundred years or so, humanity has been injecting a 
third category of ingredients: human-made and human-generated. By volume, this new genre 
consists mainly of substances already present in the atmosphere, only now they are being 
added to in unfathomable quantities ~ and they belong to the reactive families. Then there 
are the "exotics": creations of science and industry that make up a small but usually 
highly reactive percentage. Many of these compounds are totally new to our atmosphere. 
All told, society has been injecting millions upon millions upon millions of tons of 
these gases and particulates into our atmosphere at ever-increasing rates. So much so 
that the very composition of our atmosphere ~ the weave of our atmospheric veil ~ has been 
significantly and verifiably altered.

This is cause for concern because our atmosphere is in actuality a heat engine. Its 
matrix of gaseous and particulate components are the valves and pistons. This engine is 
powered by the sun’s energetic rays and the result is our weather: the global 
distribution of energy, heat, and moisture. But each compound we've introduced interacts 
with the sun’s energy according to its own unique thermo-hygroscopic-chemical profile. 
Recent weather fluctuations are little more than a physical reflection of our 
atmosphere's composition.

Remember all those environmentalists whining about pollution, global warming, and 
all that? Well, it isn't mere delusion. Scientists have been discovering and recording 
these changes since the end of World War II. For more than forty years now, satellites 
have been visually recording the stains, rips, and acid burns that we continue to inflict 
upon the veil of our atmosphere. The increasingly sophisticated information they gather continues to have ominous implications for the future as well as the present.

While the media discusses global changes in terms of global averages, keep this in mind: 
there is no "average" patch of ground or water on this planet. Pollutants aren't added as 
amorphous averages. They are injected into the fabric of our atmosphere as ribbons of 
varying concentrations and volumes. It's true that today scientists have convincing 
evidence that some global areas are experiencing a warming trend, while others are 
experiencing a cooling trend. There is nothing reassuring about this.

Think about our atmosphere as the heat engine whose role it is to seek a globally 
balanced distribution of energy, heat and moisture. This engine has evolved to a delicate 
state of dynamic equilibrium. Remember, it is the profile of temperature gradients and 
barometric differentials that provide the throttle behind this engine's drive to maintain 
its equilibrium. Inject extremes and it will react in kind ~ it makes no difference to the 
engine. It does, however, make a difference to humans and the biosphere as we know it.

Science has consistently shown that nature is always vastly more complex, interwoven, and 
unpredictable than the human intellect is capable of imagining. Why won't we allow this 
lesson to sink in? Why be surprised when weather continues to become more chaotic? 
Admittedly, no one can accurately predict how weather will change. But who can deny that 
it will continue to change, and at an accelerated rate? We can kid ourselves, but we 
can't fool nature.

I know there are mistakes in the details, I've learn much since writing those in 1995 and 2005. Still the basic outline stands firm and "my" 'prediction' is unfolding upon the face of this wonderful Earth of ours and it's global heat distribution engine, with breathtaking speed.

Yet we still have half the population and way too many business leaders and politics telling us we shouldn't trust scientists and instead should continue wasting precious time entertaining the fantasies of armchair self-proclaimed authorities.

It's a crying shame.
