During a speech in Sacramento on August 15, 2008 California Representative Kevin McCarthy claimed that fires produce more emissions than cars:
“What I have found”, Rep. McCarthy said, “because of these fires, there are studies that are showing they are producing more emissions than all of our cars are doing.”
Politifact looked into Rep. McCarthy’s statement. Here is an excerpt from their article:
Bill Stewart, a researcher at the UC Berkeley Center for Forestry, said there’s a key point missing from McCarthy’s statement. While fires emit more particulate matter, cars produce far more greenhouse gas emissions, particularly carbon dioxide, he said.
“Those are two important but different issues,” Stewart said.
Mike Kleeman, a UC Davis professor of environmental engineering, added that wildfires also emit some greenhouse gases.
“But burned areas also regrow during which time they act as a net carbon sink. Assuming a burned area regrows completely over a time of decades, the net CO2 emissions should be low,” Kleeman wrote in an email.
“Wildfires are a problem,” he added, “and we should be taking steps to reduce their frequency and intensity. But it isn’t an ‘apples to apples’ comparison to an every-day source like cars.”
Earlier this month, the Trump administration proposed rules that would ease vehicle emissions standards nationwide.

While fighting one of the largest wildfires in California’s recorded history, the company reduced the data rate for a fire department’s account to 1/200th of normal.

Six weeks after the Santa Clara Fire Department said Verizon reduced their data rate for a command and control unit to 1/200th of normal while fighting a huge fire, the company has purchased time on television networks with a commercial titled “Enabling Heroes”.
The commercial which ran during a football game this weekend showing people that are represented as firefighters, has a spokesmodel saying, “In times of crisis their calls go through and they can get their jobs done”, and the company has “a dedicated lane on our network just for first responders”.
The fire department personnel staffing Santa Clara’s OES Incident Support Unit 5262 earlier this year while battling the Mendocino Complex of Fires, one of the largest blazes in the history of California, knew they had an unlimited data plan for the equipment used to track, organize, and prioritize routing of resources from around the state and country to the sites where they are most needed.
While fighting the fire the department discovered the Verizon data connection for the command and control unit was being throttled. Data rates had been reduced to 1/200th, or less, of the previous speeds. Fire Chief Anthony Bowden wrote in a court filing that the “reduced speeds severely interfered with the OES 5262’s ability to function effectively”. The County has signed on to a legal effort to overturn the Federal Communication Commission’s repeal of net neutrality rules.
While the fire was burning, the department explained to Verizon the problem and asked the company to restore their data capability, but it did not happen quickly. After going around and around for a while, eventually the department’s administrative section had to work with Verizon and sign up for a different plan.
In the last couple of years the four major cell phone providers have advertised “unlimited” data plans, but they ARE ALL LIMITED in various ways.
The department thought their plan described as “unlimited” actually meant that. Critics say they should have read the fine print in their contract, while others say Verizon should have immediately restored their data and worried about the contract issues later after the smoke cleared. A comment in one of our articles about this issue looked as if it could have been written by a lobbyist for Verizon.
The Branscombe Fire that began Sunday morning east of Fairfield, California destroyed one residence, one barn, and two vehicles, a spokesperson from the Solano County Sheriff’s office said Sunday evening.
After it started near Travis Air Force Base the fire ran south crossing Highway 12 and bumped up against Cutoff Slough near Grizzly Island Road and the larger Montezuma Slough. Those water courses stopped the spread in some areas but the Sacramento River farther south should serve as a more formidable fire break if it continues to grow in that direction. However, Sunday evening firefighters were starting to get a handle on it and released resources from outside Solano County.
The Red Flag Warning that was in effect for the area Sunday is slated to end Monday at 1 p.m., but following that, firefighters will still have to deal with fairly low humidity in the 20s and north winds of 14 gusting to 18.

A fire that broke out Sunday morning east of Fairfield, California had burned approximately 4,500 acres by 5 p.m. according to estimates from firefighters on scene. The Branscombe Fire started near Travis Air Force Base and spread south, crossing Highway 12 which was closed in both directions until about 1 p.m. It is 38 miles northeast of San Francisco and the smoke is spreading into the South Bay area.
The media reported that at least one structure was destroyed based on observations from a news helicopter.

Live video from a helicopter is occasionally available at ABC7.
At 5:50 p.m. Sunday, judging from the helicopter video, the fire had spread across Cutoff Slough near the intersection of Grizzly Island Road and Joyce Island Road, but had not crossed over the larger Montezuma Slough. Beyond that is the Sacramento River which should serve as a more formidable fire break.
In addition to the firefighters on the ground, aircraft have been working on the fire, including air tankers, helicopters, and dozers.
The fire is burning in a sparsely populated area with few structures.
The area is under a Red Flag Warning until Monday at 1 p.m. On Sunday afternoon a weather station at Travis AFB recorded temperature in the low 80s, relative humidity of 14 percent, and winds out of the north at 20 to 24 mph gusting up to 38 mph. Conditions like that can present a serious challenge to firefighters.

Firefighting trains have been around for well over 100 years — the first ones were pulled by steam locomotives, but you rarely see them since they are used in remote areas near a fire that has limited access by the public. The apparatus usually consists of one or more tank cars that each hold more than 10,000 gallons of water and a high-volume pump that can support a master stream and additional hand-held hose lines.
The concept is to protect the railroad infrastructure, keeping the right of way open for trains. And sometimes the railroad will serve as a fire line — the application of water could keep the fire from crossing to the other side.
The videos below of a Union Pacific firefighting train were shot at the Delta Fire, the 63,000-acre blaze north of Redding, California. The first one is from ABC news, featuring fire photographer Dan Ryant. The one after that is raw footage shot by Mr. Ryant mostly from the top of the train.

Fire officials in California have released the cause of the Ferguson Fire that burned 96,901 acres of the Sierra National Forest, Stanislaus National Forest, Yosemite National Park, and state lands. They determined that it was caused by a hot catalytic converter on a vehicle that parked in dry grass at 8:30 p.m. Friday, July 13, along eastbound Highway 140 near the Savage Trading Post.
A vehicle associated with the cause has not been located. However, officials are asking anyone with information to contact the Sierra National Forest at (559) 297-0706.
Catalytic converters are part of the exhaust system on the underside of vehicles and can heat up to 1,200 degrees. After a vehicle has been traveling at speed, under a load, or not working properly the catalytic converter can get even hotter. If it is parked over dry grass, it can ignite a fire.
U.S. Forest Service personnel working on the investigation received assistance from the National Park Service and CAL FIRE.
A group of people knowledgeable about wildland fire have produced a 52-page document that attempts to assemble and summarize areas of agreement and disagreement regarding the management of forested areas in the western United States. Calling themselves the Fire Research Consensus Working Group, they looked for areas of common ground to provide insights for scientists and land managers with respect to recent controversies over the role of low-, moderate-, and high-severity fires.
Here is how they hope their conclusions will be used:
Our hope is that stakeholder groups will avoid the selective use of particular scientific papers to argue for their particular ends. Instead, they will be able to point to key shared assumptions, common understandings considering the entire body of fire science literature, and terminology to support decision-making in constructive ways. In particular, land and fire managers are a key audience for this report, as are other stakeholders and the interested public engaged in discussions about land management.
The “Executive Summary” is 6 pages long. Below is the section about high-severity fire:
“Respondents disagreed about whether large, high-severity fires have increased to a significant and measurable degree in all forest types in comparison to historical fire regimes (i.e., prior to modern fire suppression). There was strong agreement that in dry pine forests at low elevations there has been either an observed increase in high-severity fires or an increase in the potential for fires of elevated severity as the result of increased abundance and connectivity of woody fuels since the late 19th century. There was similar strong agreement about dry mixed-conifer forests in the Inland Northwest, Pacific Southwest, and Inland Southwest (Arizona and New Mexico) that there has been an increase in high-severity fires and an increase in the potential for fires of elevated severity. There was less agreement about the changes in extent, and causes of changes in extent, of high-severity fires in moist mixed-conifer forests. Although there is general agreement that high-severity fires historically played an important role in moist mixed-conifer and cold subalpine forests, there is strong disagreement over the degree of changes in burn severity patch-size distributions and associated successional conditions for these forests between different regions.
“Opinions also vary over the consequences of any increases in fire severity. For most dry forests, although there may be some disagreement about trends in burn severity and their causes, there is broad agreement that under current and projected climate, post-fire forest resilience is less than in the past. Some forest habitats, particularly at drier sites, but also in some moist and cold forest sites, show evidence of converting to more flammable non-forest vegetation or less dense forests following recent fires where large patches burn severely, especially if reburned. Reburn potential may depend on the interaction of vegetation, weather, rate of fire spread, time since prior fire, ignitions and fire suppression. Opinions are varied concerning the ecological consequences of departures from historical patterns of fire severity in various mixed conifer and subalpine forests. For example, one viewpoint supports the historical precedence of mixed-severity fire (including relatively large patches of high-severity fire), and the concept that pyrodiversity begets biodiversity. Another viewpoint asserts that increased woody fuel connectivity in combination with a warming climate trend is setting large areas of landscapes on fundamentally new trajectories, with significant undesirable ecological and societal consequences. Still a third viewpoint emphasizes that climatic changes increasingly are of overriding importance, and that new trajectories are unavoidable and thus may be considered desirable in many cases to incrementally foster necessary ecosystem transitions. The figure below characterizes these divergent viewpoints – typical of many areas of disagreement we addressed – and the potential common ground among them.
“Uncertainties associated with relative proportions of different burn severities and patch-size distributions combine to cloud key points of consensus that have important management implications. We suggest that resolving many fire science disagreements depends on greater consideration of specific geographical context. This may imply that a narrow range of field experience can limit one’s ability to accept findings that depart from that range. A logical way forward is to increase in-depth cross-regional field research experiences of the fire research community. Cross-regional comparisons of top-down and bottom-up determinants of fire activity in similar forest cover types is a fertile area of future research to examine how differences in seasonality, productivity, understory fuels, land use history, and other factors may explain some of the reported geographical differences in historical fire regimes in broadly similar forest types.
“There are several reasons for the disagreements about the amount and roles of past higher-severity fire. Both scientists and managers often transfer concepts and findings from one place to another, yet we know that “no one size fits all” for historical fire regimes, even within the same forest type. Likewise, the extent of change in abundance and connectivity of woody fuels varies across forest types and ecoregions. Some of the disagreement derives from use of different scientific approaches. For instance, there is strong debate about the fire regime inferences made from historical and modern tree inventory data, simulation models, and other approaches. We believe that application of diverse research approaches will be useful going forward. Further, multiple approaches will be useful in “triangulating” interpretations for which there is some scientific consensus (see Topic H). We challenge fire scientists who do not share similar perspectives on historical fire regimes in particular ecosystems to engage in civil discourse to better understand the reasons for their disagreement, and to objectively communicate those reasons to managers and other stakeholders. We are heartened by the positive outcomes achieved by some previous attempts when small or large groups work together to find common ground.”
