Why the West Is Burning

There are 137 large wildfires raging across 7.8 million acres in what might be the worst fire season ever

Hurricanes, earthquakes, and nuclear war, oh my. And听don鈥檛 forget to add a near-record wildfire season to that list of disasters. According to the National Wildfire Coordinating Group,听. That鈥檚 not yet as bad as 2015, which saw 8.4 million acres burned, but it鈥檚 only September and this is already the third worst year for wildfires in the last decade. It鈥檚听already way ahead of the previous 10-year听annual average of 5.4 million acres burned.

You鈥檝e seen the apocalyptic images from the Columbia River Gorge, Glacier National Park, and the Los Angeles Suburbs, but those fires are only a small part of the overall picture. Currently there are听13 active wildfires in Washington, 26 in Oregon, 23 in Idaho, 46 in Montana, and 38 in California. I could go on, but you get the idea. (.) Smoke from these fires currently envelopes an area stretching north to听the听Queen Maude Gulf, in the Canadian Arctic, west听to听Seattle, south听to听Waco,听Texas, and east听to听Columbus, Ohio.听

Why is this happening?

Extreme Heat

This year has also brought record heat to the West. Just last week, San Francisco recorded its highest temperature ever鈥, three more than the city has ever seen before. It鈥檚 been . . When I drove past the La Tuna fire, the largest in Los Angeles鈥檚 history,听the external temperature gauge in my Land Rover registered听114 degrees.

High temperatures bake听out the moisture absorbed by forests during听the extremely wet winter. Because heat leads to drier fuel, the relationship between each additional degree of temperature and the likelihood and severity of fire : every additional degree of temperature is more likely to lead to fire than the last.

The Drought Persists Despite a听Wet Winter

While the historic drought that afflicted the West over the last five years officially ended this winter, its effects are still being felt. In the Sierra Nevada mountains alone, . Statewide,听.听Most of those have not been cleared, and their dried out husks clutter forest floors, and still stand on mountain sides, creating perfect fuel for wildfires. Forests that once had open ground under the trees听are now so cluttered with dead logs that it鈥檚 become impossible to walk off-trail across much of the western Sierra.听

All this winter鈥檚 rain also led to huge growth for grasses and underbrush, which this summer鈥檚 record heat then dried out, turning it into massive amounts of tinder. Stack dry grass under a dead log, and you have the perfect recipe for a campfire. Scale that across the entire west and you have our ongoing disaster.听

Fire Management Meets Urban Planning and Politics

According to an analysis by the insurance industry, . In short, we鈥檙e building our homes in areas that naturally burn. More than听. And that construction is in those areas with controlled burns.

The other big factor limiting wildfire prevention right now is budget. All these huge fires cost tons of money to fight, and that money is coming out of prevention budgets. Every time a state or the Forest Service has to fight a fire, its financial ability to prevent other fires diminishes.听

鈥淎s more and more of the agency鈥檚 resources are spent each year to provide the firefighters, aircraft, and other assets necessary to protect lives, property, and natural resources from catastrophic wildfires, fewer and fewer funds and resources are available to support other agency work鈥攊ncluding the very programs and restoration projects that reduce the fire threat,鈥 reads . Fifty-two percent of its money went to firefighting that year鈥攁 percentage听that鈥檚 expected to grow to 67 percent by 2025. This year alone, the Forest Service is already $300 million over budget for fire fighting.

The Forest Service knows it needs to change the way it deals with fire, but it鈥檚 so busy trying to fight fires, and going so broke fighting them, that it can鈥檛 afford to.

As the Forest Service spends more money fighting fires, it has less money to spend preventing them. As it has less money to spend preventing fires, it has to spend more money fighting them. Something has to change.

It鈥檚 All Connected to Climate Change

Since 1970, . Since 1984, . The Forest Service estimates that area may double again by 2050.

Climate change is also bringing wildfires to new areas, and to a degree never before seen. Since the 1980s, the area burned annually in the northern Rockies has increased 3,000 percent. In the Pacific Northwest, it鈥檚 a 5,000 percent increase over the same period. Between 1978 and 1982, the average burn time of a fire was just six days. Between 2003 and 2012, it was 52 days.

鈥淲armer temperatures and earlier snowmelt have contributed to drier conditions,鈥 reads. 鈥淏ut cooler, more moist forests, such as those in the northern Rockies, have seen the greatest drying due to changes in the timing of spring, and the greatest changes in forest wildfire.鈥

鈥淥bserved warming and drying have significantly increased fire-season fuel aridity, fostering a more favorable fire environment across forested systems,鈥 reads听. 鈥淗uman-caused climate change caused over half of the documented increases in fuel aridity since the 1970s and doubled the cumulative forest-fire area since 1984.鈥

How Do We Pay for This?

By the end of the century, the West is projected to warm by an additional 3.5 degrees Celsius. Given the exponential relationship between temperature and wildfire, that鈥檚 bad news.

The Forest Service elaborates:

鈥淐hanging climatic conditions across regions of the United States are driving increased temperatures鈥攑articularly in regions where fire has not been historically prominent. This change is causing variations and unpredictability in precipitation and is amplifying the effects and costs of wildfire. Related impacts are likely to continue to emerge in several key areas: limited water availability for fire suppression, accumulation at unprecedented levels of vegetative fuels that enable and sustain fires, changes in vegetation community composition that make them more fire prone, and an extension of the fire season to as many as 300 days in many parts of the country. These factors result in fires that increasingly exhibit extreme behavior and are more costly to manage. The six worst fire seasons since 1960 have all occurred since 2000. Moreover, since 2000, many western states have experienced the largest wildfires in their state鈥檚 history.鈥

To pay for part of this season鈥檚 suppression budget, . But the agency is desperately in need of a major new source of funding. If it doesn鈥檛 get one, it鈥檚 estimated that the budget for other activities, like fire prevention, could shrink by $700 million annually between now and 2025.

This is not a problem we can afford to neglect. The solution to this funding shortfall is obvious鈥攆ires need to be treated like the disasters they are, and fighting them needs to be paid for in the same way we deal with other natural disasters, like hurricanes and earthquakes.

鈥淐ongress needs to step up and treat these infernos like the natural disasters they are,鈥 says Senator Ron Wyden (D-Oregon), who introduced the to congress in 2013. The bill, which has since languished in committee, creates a federal fund dedicated to fire suppression, supplanting budgets drawn from states and the Forest Service鈥檚 general budget.

Now, . 鈥淐ongress needs to act,鈥 Oregon Senate President Peter Courtney wrote in a letter to Congress last Friday. 鈥淭his is no time for politics. It鈥檚 time for action. My state is on fire.鈥
