The Colorado Wildfire and Global Warming: Is there a Connection?

From the Cliff Mass Weather Blog

Cliff Mass,

Last Thursday, December 30th, powerful downslope winds resulted in a massive grass fire that rapidly moved into neighborhoods around Superior, Colorado–a town between Denver and Boulder.

Driven by winds exceeding 100 mph that rushed down the eastern slopes of the Colorado Front Range, a fire initiated by humans moved rapidly towards populated areas, with roughly 1000 homes lost, a number of businesses destroyed or damaged, and two people unaccounted for.

Large areas of dry grass surrounded the burning homes and businesses of Superior, CO and nearby Louisville.
Within hours of the event, several media outlets including the Washington Post, the Seattle Times, National Public Radio, NBC News, and Axios (to name only a few), were making broad claims that the fires were the result of global warming (or “climate change” in the modern vernacular) or that global warming played a major role.
Politicians, such as the Governor of Colorado, blamed climate change, as did a contingent of climate activists.

The truth is different and very clear.  This event had little to do with climate change.  And it is easy to show this.
In this blog, we shall examine why this terrible tragedy occurred and what steps must be taken to prevent it from happening again.  
We will consider the necessary ingredients of this fire, one by one, and ask whether climate change could have contributed.
The Ignition Source:  No Climate Change Connection.
The fire was human-caused, with no natural ignition origin (there was no lightning).Currently, the point of origin appears to be within the camp of a fundamentalist religious group, but investigations are ongoing.
Climate change had nothing to do with the ignition.
Huge increases in human population over the region during the past 50-years obviously made accidental ignition of a fire more probable.

The Potential Ignition Location
The  Strong Winds:  No Climate Change Connection
A key aspect of this event was the strong winds, which accelerated down the eastern slopes of the Front Range of the Rockies.
Such winds are connected with high amplitude mountain waves that can be produced under the right meteorological conditions, including strong flow from the west to northwest approaching the Rockies and a stable layer near or just above crest level.  Such conditions occurred on December 30th and the strong downslope winds were forecast by high-resolution numerical prediction models (e.g., the NOAA/NWS HRRR model).

There is no reason to expect this downslope windstorm was the result of global warming, enhanced by global warming, or made more frequent by global warming. 
In fact, the opposite is possible.
Although the winds reached 100-115 mph in a few locations, some historical front range windstorms have been stronger, such as the events in 1972 (144 mph) and 1982 (140 mph).  
Downslope windstorms are not unusual along the Colorado Front Range and are most frequent during the cool season (November-January) as shown below.  There appears to be a declining trend in the number of strong downslope events, which suggests that global warming does not encourage them.

In fact, some research, examining global climate models forced by increasing greenhouse gases, found that the conditions producing Front Range downslope windstorms will become less frequent and weaker under global warming (e.g., this reference).
The Fuel of the Fire: Dry Grasses.  No Connection With Global Warming.
So if the ignition of the fire and the essential strong winds had nothing to do with global warming, the only possibility left is the fuels, in this case, the extensive grasslands of the region.  But as I will show, it is implausible that global warming played any role in the fast-moving grass fire.
As shown in the picture below (courtesy of google maps), the region just to the west of Superior, CO was characterized by extensive grassland.    These grasses grow and green up in the spring and naturally brown out and dry during the summer.   Such grasses are known as one-hour dead fuels, which means that no matter how moist they are, they can dry enough to burn after ONE-HOUR of drying conditions.
And few environments are more drying than the combination of strong winds and low relative humidities that accompany downslope wind events (the relative humidity was around 23% the morning of the windstorm).

So whether the prior period was warm, wet, moist, or dry, IT DID NOT MATTER.  The windstorm event itself ensured that the grasses were ready to burn.
So the claims by some activists that multi-month autumn drought set up the wildfire event are patently false.And the claims that global warming helped prepare the grass to burn are patently false.
Furthermore, measurements of 10-h dead fuel moisture (for plants slightly larger than grass) at the nearby USDA RAWS site (Sugarloaf Mountain) showed moisture levels of around 9% for the preceding days, which is near normal for this time of the year (9% for December).  I should note that it had rained on December 25th.

10-h Dead Fuel Moisture % at  theSugarloaf RAWS observing site.
But there is more.  
The grass was particularly bountiful this year not because of drought, but because the region experienced a particularly wet spring and early summer.  To show this, below is the observed cumulative precipitation for the past year at Boulder, Colorado, with the normal values shown as well.
Precipitation was normal to about March 1 but by June 1 precipitation was well ahead of normal…and that bountiful precipitation continued into the summer.  The result was enhanced grass growth.  And there is no reason to expect that global warming is INCREASING precipitation in spring–there is no climate model output to support that.  
You will notice that the year as a whole came in near normal. The snowpack in the mountains above Boulder was above-normal last winter by the way.

The bottom line in all this:  there is no apparent or plausible connection between the dry grass that produced this tragic fire and global warming.   
Lack of snow:  A Global Warming Connection?
 There is another claimed global warming connection with the fires, the lack of snow this year from the dry, warm conditions during this fall.  But that is without support as well.
First, having little or no snow on the ground is not unusual for the Boulder, Colorado area during late December.   In fact, only about one-third of winter days have 1-inch or more of snow on the ground (one reference here), with an average snow depth of around 1.5 inches.  And wildfires can occur in grasslands with a few inches of snow on the ground.
An interesting question is whether global warming is producing drier/warmer autumns along the Front Range (little evidence for that).   And another is whether there is an alternative explanation for the dry/warm fall this year (there is).
If global warming is important for fall weather along the Front Range, one should find a significant trend over the past decades in autumn precipitation, drought indices, and temperature.  Well, let’s take a look at this using the NOAA/NWS Climate Division Data for conditions from September through December for 1950-2020.
For precipitation (below), there is no apparent trend up or down:

And for the Palmer Drought Index, which includes temperature, there is no apparent trend, but with lots of ups and downs.

For temperature,  possesses only a slight (~1F) warming.

So there does not appear to be a long-term global warming signal in this area that is contributing to drought and drying conditions.  Or to a lack of snow
But there IS something that probably contributed to the warm, dry conditions and lack of snow this fall on the Colorado Front Range: La Nina.
We are now in a moderate La Nina year, with the tropical central and eastern Pacific experiencing below-normal sea surface temperatures.   La Nina influences the circulation of the atmosphere over the entire planet and one  La Nina “teleconnection” is dry, warm conditions over eastern Colorado.  
To show this,  I looked at the correlation between tropical sea surface temperatures and temperature/precipitation conditions over the U.S. using the wonderful NOAA ESRL site.
La Nina years are associated with drier than normal autumns over Colorado (orange/red colors)

And warmer than normal temperatures (green/blue colors).

So why blame global warming for the warm/dry conditions, when long-term trends don’t suggest a global warming signal and La Nina provides a ready explanation?  Some media folks are not earning their keep!
Major Contributors to the Disaster
Multiple lines of evidence make it clear that global warming had little to do with the catastrophic Marshall fire in Colorado.  Strong/dry downslope winds, bountiful grass for a wet spring, and human ignition explain the fire.
This was a disaster ready to happen and human actions and decisions contributed to the problem.  Let me note a few of them.
Massive Population Increase in the Area
Between 1950 and today there has been explosive population growth in the area, which has not only increased the vulnerable population but increased the potential ignition sources and fuels (e.g, the homes).  The town of Louisville, for example, saw population growth from approximately 2000 to 20,000 during the past 70 years.
Grasslands Next to Dense Population Areas
Ironically, for environmental reasons, vast tracks of “natural” grasslands have been set aside as part of the Boulder County Comprehensive Plan, with dense housing development next to wild areas (see map below showing protected Environmental Conservation Areas, with a red star where the homes were lost)

Thus, there are large areas of flammable grass adjacent to heavily populated areas, and worse than that, these grassy areas are generally upwind (west) of the developed areas.    Thus, we have an extremely dangerous situation where the areas of strongest winds, just to the east of the Front Range, are dominated by grassland.  Any ignition will result in fires that rush eastward into the populated regions.   Flammable grassland upwind of large housing developments. It could hardly be worse.
Dense House Development
With so much land put aside for wildland areas, less remains for housing and development.  As a result (and perhaps to enhance profit as well), many of the housing developments near Superior and Louisville, CO had very closely spaced homes (see imagery below).  
 Thus, once one house catches fire, neighboring homes are more likely to go up in flames.  In many wildfire situations, homes provide massive amounts of fuel to help grow and propagate the fire, something documented for the Camp Fire in Paradise, CA, and clearly evident in this case.

Highly Flammable Invasive Grasses
During the past century, highly flammable invasive grasses (e.g., cheatgrass, oat grass) have moved into the region, greatly enhancing wildfire potential.  Limited steps have been taken to deal with the problem. 

Lack of Safe Zones
There has been little effort to create sufficiently wide grass-free safe zones around urbanized areas.
Historical Fires in the Region
Fires are frequent visitors to Boulder County, but most of the recent fires have been in tree-covered terrain, often with a grass understory (see map below).  A few fires have been predominantly grass fires, but have not extended over heavily populated areas.

Global warming had very little to do with the destructive wildfire that occurred in Colorado on December 30th.   Those pushing a global warming narrative for this event (e.g, some media, politicians, and activists) are misinforming the public.  
But it is worse than that.  Blaming global warming undermines efforts to clearly define the risks and to take coherent, effective actions to reduce the chances of such wildfire disasters happening again.

griff, perhaps the single biggest threat to summer range fires in the western US is the proliferation of cheat grass, which grows like crazy in the Spring, especially a wet Spring, but dries out quickly. Cows can eat it in the Spring but can’t digest the dried out cheat grass by early summer. Us geologists, working in northern Nevada, are sure to never go into a dead-end canyon in summer with a trailing wind and some thunderstorms around. The speed of these cheat grass fires is amazing.

“And that’s the new climate change induced pattern”

Griff sees a climate change (Human-caused Global Warming) induced pattern in everything. It’s an obsession with him. It’s really delusional since there is not one shred of evidence to connect human-caused CO2 with any changes in the Earth’s climate. Griff just assumes there is. He wants you to make that assumption, too. Right, Griff?

Clearly, you can’t even be bothered to read the article. The main precipitation in 2021 was in spring and early summer. And the overall precipitation was near average for the year. There’s a graph in the article that shows you this.

What evidence do you have that the fire season was “worse and extends longer”? This fire was basically a single event caused primarily by strong winds. Oh, and humans starting a fire. Those humans are surely bad news…

Thanks for the rest of the story. Even the list of con job media is useful to see on display.

Excellent analysis, Mr. Mass.

The snow storm that helped extinguish smoldering areas after the wildfire came only a day too late. Another storm came in yesterday and left several more inches of snow and the low was about 0F this morning and the high today was only in the teens. The weather here is variably variable but pretty nice overall.

Interestingly, we had a temperature inversion today, so it was actually warmer in the mountains, where the snow continues to dump. I won’t say why I know but a little froggie said “knee deep.”

Metal roofs, brick/stucco facades, and ember ‘proof’ soffits should have been mandatory in the building codes for this fire prone region. Vinyl siding and asphalt shingle roofs (as pictured) guaranteed that the closely spaced stick built homes were highly combustible. Maybe they will learn now.

After Andrew, south Florida finally got strict ‘hurricane proof’ building codes. And after Wilma, Patricia’s old pre Andrew code rental property got mandatory steel hurricane window shutters (put up only if hurricane is coming, but with all the install hardware preanchored. Just loosen the big flat head stainless steel ‘screws’, slip on the shutter panels, retighten the screws).
And also after Wilma, all South Florida gas stations and grocery stores got mandated back up nat gas generators so gas can be pumped and refrigerated foods won’t spoil. My Publix was testing theirs yesterday when I was shopping there. Out back, steel cased, up on stilts above storm surge levels.
Our residential building has a big one in its own ‘hurricane proof’ ground floor sound insulated room to insure elevators operate and common areas remain lit.

Max, not so simple.
The insurance industry did NOT fix the Andrew or Wilma problems. They simply left Florida after Wilma, refusing to insure here at all. Policies simply not renewed. State Farm, Allstate, the whole lot of them just fled.
So we had to start our own state owned hurricane insurance company, ‘Citizens’. And part of passing that state legislation was also upping mandatory coastal building codes to keep state taxpayer insured future losses down. People in north central Florida have no incentive to subsidize South Floridians living on the fringes of the Everglades. So they didn’t.

Insurance companies have no incentive to control costs. Costs are good. They can charge more for insurance, and even with the same profit margin, they make more money when costs go up. Medical insurance is a good example. Owners have incentive, but less if they are insured.

Clearly you don’t understand the economics; if they can’t charge enough for the risk they bear, they won’t be in business for long, and loss costs are a big part of the equation.

Medical insurance is a poor example, since individuals are for the most part not all going to experience big medical bills all at once.

Weather-related “catastrophe” losses, where a large number of risks all experience major or even total losses all at once, challenge the basic business model, which is predicated on pooling of resources of many “risks” to fund the losses of those who experience them. Pricing based on pooling of many risks doesn’t function so well when entire towns burn down or are blown apart all at once.

So there is most definitely an incentive to control costs. Even in uncorrelated risk types, there is an incentive to control costs – see the Insurance Institute for Highway safety, and its contribution to pushing for more crash-worthy vehicles.

Similarly, after the big fires south of Denver 6 to 8 years ago, when ~450 houses burned down in consecutive years, several insurance companies simply bailed out and would no longer insure us. Allstate left us high and dry, after gleefully accepting our premiums for the previous 20 years.

At the end of the day, it’s a business. When you clearly can’t make money when the risk vs. price proposition is considered, companies will stop writing the business.

How may of the houses that burned down were built with wood? And why do the CO building codes permit that in wildfire prone areas?

When areas become “uninsurable,” it’s usually because of stupid zoning and building practices.

Take a good look at Tony Heller’s video and that nice aerial view of the (undoubtedly all wood-framed) housing. As they say, “common sense is not so common.”

I’ll give this some more “color” for you. The truth of the matter is that Florida property insurance prices were far too low, owing to intensive competition and complacency due to low hurricane losses insurance-wise keeping rates depressed. There were not any big Florida hurricane losses for decades before Andrew.

See a list here:

Andrew was a wake-up call to the complacent insurance industry that caused the pendulum to swing the other way – to insurers simply exiting the state when rate “corrections” would not be granted overnight. Also remember that Andrew came ashore in Homestead, hardly a “ritzy” area; had it come ashore in Miami, the loss would have been staggering – and insurance companies were re-assessing their exposures (which caused them great alarm) and “modeling” and seeing just how much worse it could be when the next “big one” hit, which was no longer something that hadn’t happened in decades.

While it is true that the insurance industry did not “fix” the building code problems, it didn’t create them either. Florida should have required much tougher building standards to begin with, but did not. And along with many other states, Florida had its insurance department fighting to keep rates “affordable” which is to say below what they should be in high hazard areas (in this case, much of the state). Many states to this day have “wind pools” and similar government sponsored mechanisms designed to make insurance “affordable” which encourages “development” in risky areas without those who live there bearing their true share of the costs of doing so. As with most government interference, this has made matters much worse. “Citizens” is yet another mechanism to artificially depress prices compared to where they would “float” if risk-based, and only luck has kept it solvent so far.

In a similar vein, I was privy to an analysis regarding wildfire risk in California. The result didn’t surprise me, and won’t surprise anyone on here, except maybe Griff. The driver of higher CA wildfire insurance industry losses is…wait for it…NOT that wildfires are more numerous or that bigger areas are burning, but that…we are building more and more houses in fire prone areas. If California did their building codes right, houses constructed in the “wildland interface” would be required to be constructed using steel reinforced concrete, not WOOD.

We lived in Boca Raton, Florida, in the late 1980s. Our rented house was built in the 1960s and had full concrete block walls and a roof made of heavy concrete tiles. Such construction would resist a Hurricane strike – the only need was to shutter up the windows & doors.

I was amazed to see the destruction caused by Andrew where the much newer housing was basically made of matchsticks. I thought it insane that buildings constructed that way were permitted in Florida, with its long history of major hurricane strikes. They learned the hard way.

As you say, there are also straighforward ways of building houses to resist fire – this most certainly ain’t rocket science.

The saying “there is no bad weather, only inappropriate clothes” applies even more to the construction of homes.

Very odd. Why are there no typical blackened, charred structural remains? Why is the debris white? I saw no black and burnt appliances within the white debris. It is physically impossible for a wildfire to get hot enough to reduce a stove, etc, to ash. What happened here?

@Enji at Rosemary Rose Quartz  I know, I have watched the 6:30pm abc news the last two tonight’s and they show plenty of eveidemce showing evergreen trees and others all fine right next to houses burnt completely to ash along with cars nearly incinerated. Also, how does anyone not realize that the tempature in that area of CO is usually 40 degrees or so this time of year….how does a wild fire and dry conditions occur during a CO winter…I can understand the sheep thinking it’s a wildlife if CA cause it’s always hot and dry there but not CO in winter

(Update: as of 12/31/21 number of hosues destroyed has grown to 1,000+ Still no reported casualties.) For those confused, here is a summary: This fire was on an unstoppable rampage through metro Colorado. Over 1000+ homes destroyed. Couldn’t bring in any form of air support due to the 70 to 110 mph winds and extremely low visibility. Most destructive fire ever in Colorado. Luckily it is now snowing, preventing the hot spots from growing. No deaths are yet reported, likely won’t stay that way for long. Considering we haven’t had any significant moisture since summer it spread uncontrollably quick. The cause of the fire is still not confirmed, though AT THE TIME OF FIRST WRITING THE NEWS SAID IT WAS CAUSED BY A DOWNED POWER LINE. -Updated version as of 12/31 at 7:00 pm

I’m a neighbor. I rode my bike to Avista last Saturday before the snow got heavy and took a lot of pictures of the smoldering neighborhood south of Dillon.

The road traffic now scares me so, I ride a mountain bike and pretty much stick to the trails. Broomfield to Boulder is a long ride for me.

Just curious.
The plains in the US had routine wide spread grass fires before it was settled.
Some native plants depended on the fires to crack open their seeds’ shells to repopulate the areas burned.
Was this area one of those areas that routinely had wide spread grass fires?

Not necessarily wide spread, but I would imagine frequent. The following discusses the fire ecology around here.

Lived in Chicagoland for many years, on the true prairie eastern fringe. And we had remanent oak prairie savannah on my SW Wisconsin dairy farm—burr oak prairie proofs. The Front range high grasslands are NOT true US prairie. Too high, too dry, not enough deep topsoil. The rough dividing line can be seen ecologically in western Nebraska—prairie versus ‘high prairie’. It is true that true prairie needs fire to regenerate, no different than western mountain lodgepole pine ecosystems, but for different reasons.

Oklahoma and surrounding areas have a lot of wildfires, most of which are in unpopulated areas.

When I look at the picture of those two houses, they appear to be correctly spaced. The garage wall, being closest to the property line, has no windows.

So, as far as I can see, there are no building code violations.

There are the lovely flammable wooden gates between the houses.

I bet the siding is vinyl. It doesn’t burn but it does melt and expose the studs to fire.

There’s a vent up near the peak and I bet it’s a cheapie that embers will easily pass through.

There are also the lovely heat -trapping overhangs.

If you knew that your subdivision was susceptible to a fire storm, you wouldn’t build like that.

The question is then, what did the builder and the building inspector know, and when did they know it?

I know we aren’t supposed to be able to sue the government, but after the Edmond Fitzgerald went down, the insurance companies spent a pile of money investigating whether the navigation charts might have been in error.

I’ve owned two houses in Louisville. Moved a little further east because I liked more space.

Anyway, there is some vinyl siding, not usually original. Most of the builders in that area used some kind of wood composite to accent stone and brick. In the high end homes, tile or something similar is used as roofing. There used to be a lot of cedar shakes.

It would be good to have the west face of houses to be more fire resistant.

 On the east slope of the Cascades, I’ve had false-stone (Versetta) put on the bottom and Hardie® Plank Lap Siding above that. I’ve cleaned out all nearby trees and shrubs. See FireWise.

Photos I’ve seen of the CO subdivisions show lots of trees and shrubs between and close to the houses. These are places for embers to land. Look under such for piles of leaves.

Look up Hardy Board, it’s thin sheets of concrete sided as siding.

Vinyl siding isn’t prevalent out here.
Here for me is a bit east of the fire but with a sister near the fire in Lafayette.

Oh vinyl siding will most definitely burn if you get it hot enough, and once it gets started it burns furiously and is difficult to extinguish.

Thanks for bringing us this good, thorough report. Of particular interest to me – and of significant disinterest to the warmers – was the extremely wet springtime we had in Colorado. Copious rains along the front range lasted from mid-March till mid-August. Early and prolonged rains don’t make for a coherent preface to the drought narrative, but this catastrophe started with heavy growth of range grasses west of Boulder County.

It’s a curious oversight that the this fact is omitted in the scare stories. By the time the rains stopped, we had a bumper crop of grasses and weeds growing. In my suburb of Denver, up until the snow storm of the last few days, I saw tall stands of crested wheat, bent, Indian rice, bluestem, smooth brome, oat grass and the above-mentioned cheat grass. Russian thistle, one of the invaders that grows to be a prominent bush, snaps off at ground level and tumbles, and must have been a significant carrier of the fire into the Boulder communities. They can be seen whirling through some of the videos that have shown up on line.

That’s all true. The grasses had a good year, and I never saw so much curly dock as this past season. Patches of it stretched for miles.

Had to look that up. Different invasive than the bane of my SW WI dairy farm, burdock.
Curly dock thrives in wet soils, so biological proof that this growing season was wet so grasses were extra abundant.

Curly dock will grow in spring and early summer where there is ample moisture. There is a tap root and there are ample seeds for new plants. Then it can dry and appears a rust-red color. I always have a few that I cut and bag; something for future archaeologists to ponder.

Yes. Right as rain. Those responsible for the fire, the guilty parties, are the drafters and signatories of the Boulder County Comprehensive Plan:

Board of County Commissioners (BOCC)
Deb Gardner
Elise Jones
Matt Jones

Planning Commission (PC)
Mark Bloomfield
Sam Fitch
Leischen Gargano
Ann Goldfarb
Dan Hilton
Sam Libby
Gavin McMillan
Melanie Nieske
Todd Quigley

These are politicians who jammed homes together downwind of grassy fuel-laden “preserves”. They established the conditions that led to the catastrophic inferno. No doubt about it. Foolish, greedy, blind, careless, virtue-signalling, pandering to UC numpty quackademics, as Far Left as they can be, and incompetent beyond belief.

The citizens of Boulder County are also to blame, for allowing chowderheads to set them up for fiery disaster, as are the State pols including Goober Jared Polis who also approved and celebrated the deadly chowderhead plan.

Will anyone of these apologize, or take responsibility, or learn from their errors? Don’t hold your breath. Stupid is forever.

Just like everything and everywhere else, “climate change” is your one stop get out of jail card.

If there is an epidemic out there it comes from blaming people’s own failures on climate

Thanks, Cliff. Well done.

High winds caused by a chinook or föhn wind. It happens frequently on the Front Range as everyone who lives there knows. Add fire and the results are devastating, as Californians and PG&E know.

The fire was human-caused, with no natural ignition origin (there was no lightning).Currently, the point of origin appears to be within the camp of a fundamentalist religious group, but investigations are ongoing.

Ummm… there was more than one fire. The Marshall fire seems to have originated at the church (or “religious community”) property (or “fundamentalist religious group” or “cult” as some like to say because using marginalizing terms makes it easy to blame, when it could have just been an accident).

The Middle Fork fire to the north did not start there. Fyi.

About 84% of wildland fires can be traced back to humans.
In this case it could just be improper wiring in a chicken coop.
All wires should be in conduit and all junctions in boxes.
I think that is a nation-wide code – not positive about it.

“The windstorm event itself ensured that the grasses were ready to burn”

It is the response of the 1-hr fuel bed to humidity that ensured that the grasses were ready to burn. However, wind does exacerbate drying of the fuels and importantly, is a significant control knob for direction of spread and rates of spread -ROS (among some other factors). I’m assuming that’s what Cliff meant.

Blaming global warming undermines efforts to clearly define the risks and to take coherent, effective actions to reduce the chances of such wildfire disasters happening again.

Never let … go to waste — as an excuse for increasing political power.

This article claims that weather forecast models are now being used to show the strong relationship (attribution) between nasty fossil fuels and extreme weather. This is accomplished by running a weather forecast model multiple over such an event, each run using different concentrations of atmospheric CO2.

Are atmospheric CO2 concentrations really part of weather forecast models? If so, why?

From the article: “This event had little to do with climate change.”

This event had *nothing* to do with climate change. There is nothing to connect this event to humans causing CO2 changes in the atmosphere. There is nothing to connect the way the atmosphere behaves with CO2.

Doesn’t the CO2 increase cause increased foliage growth. If there’s more foliage isn’t it likely there’ll be an increase in fires?

I graduated from CU in the middle 70’s. The students were just as radical then as now, but with different agendas. Pronouns weren’t the problem.

The Pine Beetle infestation was just getting started. The Forest Service wanted to blanket spray any infected region to prevent the spread of the insect. The environmentalists were adamant that spraying was not necessary and that it could be controlled by the landowners. Their argument was that blanket spraying would kill all the insects and disrupt the ecological system then existing in the sprayed area. The environmentalists were the squeaky wheel and so the governing bodies followed the lead of a group of people who knew nothing of forest management.

What was allowed. If a landowner found an infected tree on his/her property, they were allowed to cut it down, section it, cover with plastic and then spray to kill the bugs that were infecting that one tree.

Fast forward 50 years. Anyone traveling through Colorado cannot help but notice the large swaths of beetle killed timber. Rocky Mountain National Park was a prime example of a dead Lodgepole pine forest. Colorado experienced two of it’s largest fires in history; East Troublesome ( Rockly Mountain National Park ) and Cameron in 2020. Both fires were fed primarily by beetle killed Lodgepole Pine.

One wonders if those fires would have occurred if the Colorado governing bodies would have listened to those who knew how to manage forests instead of the squeaky wheels.

I don’t know the dates of the 1972 Chinook winds that Mr. Mass speaks of here, but in late January or early February of 1972 I was living temporarily in Laramie, Wyoming. One evening ferocious Chinook winds took out the power. In the dry air, full of dust and debris, we had the most spectacular display of St. Elmo’s fire I have ever observed. Every tree branch and every aluminum window frame was glowing in the darkened city. Buildings outlined in indigo. Occasionally the darkness was interrupted by a violet-colored explosion to the north of the city — probably arcing from some electrical equipment at a substation or possibly from downed power lines.

Chinook winds are nothing new or out of the ordinary.

January 7, 2022 8:31 am

Dr. Mass mentions only briefly the major point of the fires: “homes provide massive amounts of fuel to help grow and propagate the fire”. As was true in Paradise, CA, the homes themselves were the most combustible thing in the fire path. Had the grass fire rushed into a neighborhood of brick homes there would have been no disaster.

Building codes could have prevented the worst outcomes. These would have included cleared “fire safe zones” around the neighborhood — mowing of grass or brush in a 50-100 yards fire barrier, non-flammabe roofing and siding, proper spacing between homes……

The images of the aftermath show homes burnt to the foundations, while conifers in the yards stand untouched. Less flammable home standing unharmed while homes on either side have been consummed.

Here in Colorado Springs, we had 90 mph winds a week or two before this event. And Manitou Springs had 100 mph gusts. Lot of power outages, downed trees and downed fences. Part of my fence broke off and needs replaced. Where I live, everyone has underground utilities, so no power outages here.

Insurance companies, pah! I built our house in Crystal Park, a gated community in the hills above Colorado Springs. It is made of E-crete, a foamed concrete that acts like a high-tech adobe, with stucco covering and a metal roof and windows. The vegetation around it was trimmed to Colorado’s highest wildfire standards, the LPG tank is buried, I have firefighters’ gel and a generator to keep our well working, and our fire department is about 150 meters away. Is all this work reflected on my home’s insurance premium? No. they assign risk based solely on location. After the Waldo Canyon fire I had difficulty in even finding an insurer. Homeowners here have little financial incentive to prepare against wildfire.

Here in Southern VT we have had some very spectacular sunsets in the last 10 days. Right after sundown the sky turned a deep brilliant red interspersed with striking blue and green patches. Extremely unusual, reminded us of some of the intense Auroras from 30 years ago.
Was not aware of this fire until now, but I think it may have caused the extreme sunsets.
