I have offered a "valid argument", indeed an historically significant
argument - you simply cannot accept that these cycles of drought and
related el Nino/la Nina warming and cooling have quite strong impacts
upon the environment of the West.

Why would you possibly give a fig what _I_ believe concerning this?
Furthermore, after denying and running away from the hard evidence I
have already presented, (which ought to give even a witless troll like
yourself a clue as to what _I_ believe on the matter) you persist in
floating these disingenuous inquiries in lieu of simply acknowledging
the answers you have already been given.
The reason you do this is because your manic nature is incapable of
accepting that others may have answers that diverge from your narrowly
focused and overly rigid ideological dictums.
You suffer under the weight of your own indoctrination and it bears
particularly hard upon you when valid and reasonable refutations are
offered.
This is because you are an unusually insecure and ergo intolerant
persona, and truly have been for your entire Usenet lifespan.
Few and far between are examples of where anyone has been able to engage
in a two-way discussion with you because you are incapable, regardless
of the subject, of accepting there is any way other than your own.
The sputtering rage this invokes within you leads you to compulsive
multiposting and rampant post-editing when contradicted, and finally the
need to simply wear your respondents into the submission of abandoning
the thread.
I pity you the hellacious mess your real life must be with these toxic
personality traits in control.

Well actually the relevant portion, as regards the Colorado fires and
four corners area is not addressed in this url. It focuses primarily, in
its look at North America, upon the Great Plains of the US and Canadian
prairie provinces.
Do try a more relevant cite.
Again, and quoting from your cite:
"Past land use and management practices including heavy livestock
grazing, fire suppression
and introduction of exotic annual plants are believed to have led to
current conditions."
In other words, and hopefully this is not too obvious for you to grasp,
some now abandoned land management practices did produce an effect.
This particular effect however is NOT the cause of the present drought,
nor is it the cause of the present fires (which have flared in half a
dozen uniquely different ecosystems within the Colorado and greater
inter-mountain West).
This is the rather well-chronicled reality that you have been unable to
come to grips with - modern MAN has not created the el Nino/la Nina
oscillation.
It has predated developed human industrial society and produced
precisely the same effects this time as in past cycles.
Again:
Did "Americans" desertify the Colorado plateau in the 16th century?

When records of drought for the last two millennia are examined, the
major 20th century droughts
appear to be relatively mild in comparison with other droughts that
occurred within this time frame.
Even the 16th century drought appears to be fairly modest, when compared
to some early periods of
drought.

Anyone can agree that human activity has had obvious micro scale impacts
upon local climates such as the urban heat island effect (paving and
roofs) or the dust bowl events of the 1930s, which were largely
corrected with contour plowing, center pivot irrigation and wind break
plantings.
However, something has made it hot and dry _all over_ the West this year:

What is La Ni�a?
La Ni�a is characterized by unusually cold ocean temperatures in the
eastern equatorial Pacific, as compared to El Ni�o, which is
characterized by unusually warm ocean temperatures in the Equatorial
Pacific. Click here for a whole list of frequently asked questions.
Previous Cold Phases
La Ni�as occurred in 1904, 1908, 1910, 1916, 1924, 1928, 1938, 1950,
1955, 1964, 1970, 1973, 1975, 1988, 1995
Typical La Ni�a Impacts
La Ni�a tends to bring nearly opposite effects of El Ni�o to the United
States � wetter than normal conditions across the Pacific Northwest and
dryer and warmer than normal conditions across much of the southern tier.
And in Colorado:
And in Arizona:
http://www.climas.arizona.edu/drought-tracker/jan2011
The La Ni�a event is currently classified as moderate to strong; it has
maintained its strength over the past month and is one of the strongest
events in the last 60 years.
� Total winter precipitation in the Southwest during all past La Ni�a
events has been near to or drier than average; the strongest La Ni�a
precipitation signal in the Southwest occurs from January to April
Widespread precipitation in late December punctuated a very dry
two-month period during which many regions received no rain or snow.
�Areas in southern Arizona and New Mexico are drier than average despite
recent storms.
� Recent storms demonstrate that during La Ni�a events, precipitation
can vary both in time and space, with greater variability in northern
regions.
� Early winter snowpack in Colorado and Utah, from which a large portion
of Colorado River and Rio Grande runoff originates, is above average.
� Precipitation forecasts call for dry conditions in the Southwest for
the rest of the winter.
...and that is precisely what happened, la Nina shut the spigot off and
we ended up in a drought...
That's not the answer you wanted, but it is the answer you're going to
have to live with.
And predictably we both know you can not, so really this thread will run
on ad nauseum as a ode to your utter intellectual intolerance and
manifest personal insecurities.
So enjoy!
