“Changes in climate can potentially shape the environment in which we operate and the missions we are required to do.”
– Department of Defense Climate-Related Risk to DoD Infrastructure Initial Vulnerability Assessment Survey (SLVAS) Report, January 2018
The famously liberal agency known as the U.S. Department of Defense conducted an extensive study on how climate change will impact its operations. Military infrastructure is already being affected, and the military will increasingly deploy personnel to repair that infrastructure, respond to humanitarian crises, and engage in conflict zones shaped by climate-related instability. In short, climate events mean billions, if not trillions, of additional dollars spent over time.
Call it climate change, cyclic weather patterns, extreme weather, or just bad juju, the military is planning, strategizing, and adjusting. It’s a conservative but pragmatic institution. Blood and treasure tend to shift the conversation away from performative rhetoric and into action.
And while the scale is smaller, how we recreate in the outdoors will change for similar reasons.
Originally written in 2018.
Revised in 2020.
Then again in 2022.
And now once more in 2025.
Sigh.
Consider some items in recent years:
- Stage 2 (no open flames) restrictions make those who long for the romance of the campfire look elsewhere.
- And too many more to list since I wrote this article back in 2018
Peering into the Magic Eight Ball yet again, it seems that how we recreate in the outdoors will drastically change in the immediate years ahead, a topic I’ve touched upon before. However, this summer has ingrained the topic even more deeply into my mind.
This humble article can’t cover all the facets of this extensive topic. An ambitious person could easily write a Ph.D.-level paper on this subject.
I am not that person.
UPDATE 2020: I wrote this article two years ago about the challenges outdoor people face with the changing climate. Unfortunately, the piece held up as I looked at the smoke in my desert town. And much worse in California by leaps and bounds.
What did I not predict? How a global pandemic affects travel, economic resources, and the effectiveness of our firefighters and first responders outdoors.
But a few main points immediately come to mind:
- The small long-distance hiking community will have to think long and hard about what constitutes a “real” thru-hike. Perhaps a minor issue in the grand scheme, but a topic people are passionate about. And a microcosm of what is ahead. Meaning people will need flexibility in planning and defining their outdoor experience.
If an area is more or less closed indefinitely, is a thru-hike invalidated?
Is it worth road-walking an area with excessive smoke just to claim completeness of a hike?
Does taking a shuttle around the closed-off area make your hike less somehow?
Is flip-flopping to avoid excessively snowy, smoky, or closed areas and returning later a perfectly acceptable thru-hiking strategy?
I know my answer (hike, have fun, and be safe), but I know others feel very different. Changing weather patterns may change other minds, though.

- Fewer dollars for maintenance, infrastructure, personnel, and equipment. The USFS budget is becoming vastly depleted by all the firefighting in recent years. The same problems plaguing the US military due to climatic issues are plaguing the USFS, too. With a fraction of the budget versus the military, of course. BLM, NPS, state, county, and other local agencies have similar issues. Fewer dollars for non-firefighting priorities means other projects go by the wayside.
- Poor air quality makes time spent outdoors difficult, if not downright dangerous; All that smoke makes breathing difficult. And too much smoke means short-term and possibly long-term health conditions. Esp. If you are already immunocompromised.
- Outdoor plans change, and people have to scramble. It’s tough to plan a hiking trip, rafting jaunt, or camping trip if the destination has a good chance of being closed months after you make your initial plans. Not everyone has the luxury of making new flight plans, changing when and where to do a multi-week excursion, or driving to an alternative location.
- The local economies will take a hit. People have changed their camping plans due to the smoke and fire restrictions, never mind the closures. Naturally, even with no fires, heat waves cause people to recreate less and stay in the cities. And if the water levels are low, so much for rafting trips. That means fewer people using restaurants, lodging, local services, etc. A season or two *might* be able to be weathered. In the long term? Places close, a town loses a good chunk of its economic base, and the services an outdoor recreationist needs no longer exist in the semi-ghost town.
- More tropical storms and hurricanes will cause flooding, blowdowns, and other damage. This could result in increased volunteer hours or funds for trail repairs, as well as trail closures of varying lengths, and damage to infrastructure along the routes, including shelters and ranger stations. And again, the areas that depend upon outdoor recreation for their economy will suffer financially.
- Excessive fires mean much less ground cover. And possible floods. Floods are often the second punch of the wildfires. Again, fewer dollars for other projects. And a hit on the local economy for months, if not years.

- Fires, retreating glaciers, floods, and other climate-related conditions alter the landscape. The draw for people coming to a park, wilderness area, or scenic area becomes less, in addition to the more challenging use of the outdoor space. And, to emphasize a theme, the region’s local economy is affected.
- Drought conditions can and have closed down ski areas—another vicious economic cycle for many areas relying heavily on the “New West” recreation economy.
- Wildfires make timber harvesting more expensive and cause lumber prices to rise. Among other resources. Even from a non-outdoor recreationist standpoint, the climatic shifts where we recreate impact the overall economy. Higher costs to access the wood or other resources ultimately result in more expensive products made from these resources.

Times changin’gin’. And so are the weather, the conditions, and where we hike. A wise outdoor recreationist will follow the Pentagon’s example and acknowledge the New Normal and be flexible with their planning. And think of what it means to them personally in how they make plans in the backcountry.
UPDATE 2022 – This article came to mind with heat waves, fires, and flooding in outdoor areas. Sigh. Along with some articles I wrote since I first published this article back in 2018:
- Ending campfire romanticism – I posit that it’s time to end backcountry campfires. Don’t think they have a place in today’s changing world for a variety of reasons.
- The Last Journey: What’s a thru-hike or similar journey when the trails and the places it goes through get closed every year?
- Planning Trips – All about the AQI – A wise outdoor person plans trips around the new reality of monitoring the Air Quality Index (AQI)
UPDATE 2025 –
With fire (again) in the La Sal Mountains, evacuations near Black Canyon of the Gunnison National Park, and the destruction of iconic places on the North Rim of the Grand Canyon, this article has unfortunately become more and more relevant, seven years after I first wrote it.

Of course, the recent cutbacks to the U.S. Forest Service and other agencies will only make the overall situation worse.
Additional material:
Here are some further reading and viewing materials that may interest some.
- Cadillac Desert by Marc Reisner
The novel The Water Knife put it:
“There are other books. Lots came later. You can read Fleck or Fishman or Jenkins or others online.” He nodded at the book in her hands. “But I always think people should start with this. It’s the bible when it comes to water.”
“The bible, huh?”
“Old Testament. The beginning of everything. When we thought we could make deserts bloom, and the water would always be there for us. When we thought we could move rivers and control water instead of it controlling us.”
To know water is to understand the West. Start with Cadillac Desert.
As I wrote earlier:
“…a documentary of one of the worse ecological disasters in modern history. Certainly not an easy watch, but much like Cadillac Desert, all persons who love the American West should heed the lessons told. When hubris meets natural and financial disasters, a tale is told that cuts deeps. The personal accounts of the survivors of The Dust Bowl are emotionally gripping more than seven decades after the events take place. The Dust Bowl also shows the parallels for today that we are repeating with our modern hubris. Next to The Civil War, The Dust Bowl may very well be Ken Burns’ best documentary. But at a relatively short four hours, more easily watched.”
John Wesley Powell predicted much of our current status, even beyond the ongoing climate shifts:
When all the rivers are used, when all the creeks in the ravines, when all the brooks, when all the springs are used, when all the reservoirs along the streams are used, when all the canyon waters are taken up, when all the artesian waters are taken up, when all the wells are sunk or dug that can be dug, there is still not sufficient water to irrigate all this arid region. –John Wesley Powell, 1893. Speech to International Irrigation Congress in Los Angeles
Read the classic account of what caused Powell to formulate many of the thoughts that proved to be prescient.
Despite the sensationalistic title (probably not chosen by the author), the book Climate Wars is an even-handed, informative, and entertaining (!) look at what could happen as the world warms up and experiences climatic changes. But from a geopolitical and military viewpoint. Gwynne Dyer is an award-winning author and military historian from Canada.
- Everything Change makes an interesting and free CliFi anthology series. You can download all three parts of this collection for free. Download – VOLUME ONE – VOLUME TWO – VOLUME THREE
In particular, further reading I have mentioned both recently and in the past includes the CliFi story of “Victor and the Fish.” Set in Montana, the story seems less like science fiction and more like reality.
There has recently been several rescues of hikers overcome by heat while hiking the AT in Maine. This wasn’t part of my planning for the Mahoosucs.

Wow. Rather disconcerting!
Hi Paul, I like how you keep coming back to this subject as a reminder that things are changing. Even in just 12 years of being in the Southwest I’ve noticed increasing fires and a breakdown in weather patterns. I’ve specifically seen how monsoon season is deteriorating – it lasted for just one week here in Bryce this summer! I wonder what the West will look like by the end of our lifetimes. For example will pinyon / juniper overtake the ponderosa forests, and will sonoran desert replace the current PJ zones? It’s only a matter of time, but how… Read more »
It is scary, indeed.
Looking through the long lens of history, we (as in humanity) will get through it OK. However, the next two or three generations could be in a world of hurt.
Generations from now, historians will clinically discuss the climate upheavals and the socioeconomic changes in humanity. Those of us living through it will see things change so much. With many people suffering in the process.
I don’t think there were or are any Stage 3 closures in southern Colorado.
A danger I didn’t see listed is the new extreme winds that seem to be a product of climate change. We had record wind speeds and duration in southern Colorado. Within the Bark Beetle kill areas this is going to make hiking in windy conditions very dangerous.
There was in 2018 when I wrote the original version of the article.
You are probably correct about the winds.
Appreciate you bringing attention to a couple of classics with Cadillac Desert and Beyond the 100th. Anyone wanting a basic understanding of the continental US (climate, ecology, history…. the whole ball of wax) should read those 2. Something you might relate to or may already know; the stream crossing at the cover shot of your post “3 Days at the End of Winter” on February 22nd used to be pretty difficult to negotiate without getting wet and could involve going quite a ways upstream as well as some tricky rock-hopping. Last time I saw it in April of 2019 it… Read more »
Indeed. A bit of irony there,
