BreezoMeter’s Guide To Understanding Wildfires

With increasingly unpredictable global wildfire seasons garnering more public attention, many questions emerge about the climate change correlation, different health impacts, and how sustainable, climate resilient solutions can help protect people, infrastructure, and properties from these extreme environmental events. We answer these questions and many more right here!

What Is a Wildfire?

Experts define wildfires as unplanned and uncontrolled fires occurring in natural terrain, i.e. a forest, prairie, field, grassland, etc. We can break wildfires down into three main types:

  • Ground fires – These occur when the roots of plants and other organic matter under the soil catch fire. Ground fires can smolder for a long time until conditions, such as fuel availability, are right for them to grow into surface fires.
  • Surface fires – These blazes burn dead or dry vegetation spread on the ground or just above it, such as dehydrated weeds and shrubs, as well as dry foliage.
  • Crown fires – As the name suggests, these crown fires burn through tree canopies mainly, making them more susceptible to wind. Because the typical canopy consists of interconnected vegetation, crown fires can spread quickly.

How Do Wildfires Start?

How do Wildfires Start?

Fires need fuel, oxygen, and some kind of spark to ignite them in order to start. Certain weather and climate conditions can often combine to make wildfire events more likely and directly impact how quickly they move or where they spread. Extreme temperatures, dry weather, and atmospheric instability can all contribute to the ignition and intensification of wildfires. 

NASA research recognized lightning strikes as a major contributor to North American wildfires starting from natural causes. In fact, lightning has sparked some of California’s largest fire outbreaks. With man-made wildfires, the origins vary between campfires, burning debris, fireworks, discarded cigarettes, arson, utility line malfunctions, and vehicle or equipment accidents.

How Do Wildfires Differ From Local Fires?

Experts distinguish between wildfires and other fires via a number of key parameters: their considerably larger size, the speed with which they can spread, their unpredictable behavior, which makes them liable to change direction unexpectedly, and their ability to cross barriers such as roads or rivers more easily. Wildfires can be characterized by the cause of their ignition, the material they burn for fuel, and the way they’re impacted by weather. 

Are Wildfires Getting Worse Due To Climate Change?

A growing body of research certainly points to this conclusion. The EPA warns that the average area burned by US wildfires annually has increased since the 1980s, with the largest annual wildfires, all occurring in the past 20 years, also coinciding with many of the warmest years on record. The World Economic Forum found that global fire weather seasons have grown 27% longer on average since the 1980s and the annual number of days with ‘extreme fire weather’ have become 54% more frequent. 

Further research projecting climate change’s impact on future wildfires suggests the number of extreme fires and their subsequent burnt area will increase dramatically in the coming decades.

What are Some Different Types Of Fires? 

Firenados (or Fire Whirls): When Fire & Tornadoes Mix Together


A firenado, also known as a fire tornado or a fire twister, is an extremely dangerous phenomenon in which a wildfire creates a large region of extremely hot that interacts with cooler air higher up in the atmosphere. The mixture of updrafts and downdrafts causes atmospheric instability that creates a circular pattern of air, similar to a ‘dust devil’, with the added danger of whirling flames.

Planned Fires & Prescribed Burning: Why This Happens

The term prescribed fires, also known as prescribed burns or controlled burns, refers to the controlled use of fire to burn a certain piece of land. These prescribed fires take place under specific weather conditions and are managed by fire experts who understand how to prevent the blazes from getting out of control. The reasons for prescribed burning include forest health maintenance, biodiversity protection, and even reduction of future fire risk. 

Fires Caused by Slash+Burn Farming

Low-cost ‘slash and burn’ farming methods are utilized by farmers in particular countries, especially in the region of Southeast Asia. These slash+burn methods involve burning trees and plants to prepare fields for cultivation. They work by clearing the land and creating a nutrient-rich ash layer on top to help fertilize future crops and reduce the presence of weeds.

The smoke from these slash and burn fires is a major contributor to Southeast Asia’s seasonal haze problem.

What Are The Visible & Invisible Dangers Of Wildfires?

Direct Loss of Life

The WHO estimates wildfires and volcanic activities have affected 6.2 million people between the years 1998-2017 and caused 2400 direct attributable deaths worldwide due to suffocation, various injuries, and burns.

Lost Homes & Buildings

Experts commonly measure wildfires in terms of how many hectares they burn, and some also include the number of lives and building structures lost in the total summary of a wildfire’s impact. From 2005 to 2022, the US alone saw an estimated 97,000+ structures lost – 17,663 of which occurred in 2020.

Loss of Essential Services

Wildfires can take essential infrastructure offline and make people and businesses lose access to actionable life-saving information in crucial times.

  • Cut-off scenarios can also occur as a precaution: during that same year, major US utility company PG&E cut power to more than 50,000 homes due to a period of high winds and low humidity conditions that could potentially create catastrophic wildfires in the area. The previous year, the company filed for bankruptcy after a wildfire caused by its power lines burned hundreds of thousands of acres.

Toxic Smoke Pollution & Outdoor Air Pollution

Wildfire smoke consists of a complex blend of toxic gasses and small particles, of which particulate matter below 2.5ug in diameter (PM2.5) poses the greatest risk to our health during a wildfire, and presents a bigger risk to vulnerable populations including people suffering from heart and respiratory diseases. Wildfire smoke significantly contributes to Particulate Matter levels in the air, thus it can directly worsen outdoor air quality. The impact isn’t limited to local regions either. Such air pollution has been known to drift across whole continents, and wildfire smoke is liable to impact a variety of regions outside the fire range.

Live smoke maps that can visualize local air quality at a high resolution provide an effective tool for limiting exposure to this harmful air pollution and enable live adaptation to extreme environmental events, a key factor for improving climate resilience. 

Smoke-linked Allergies?

While wildfire smoke is a known health concern and can penetrate our respiratory system much like pollen and induce an inflammatory response, it isn’t classified as an allergen. However, smoke inhalation shares similar symptoms with allergic reactions including irritation of the nose, throat, and eyes, shortness of breath, coughing, headaches, and more. 

According to Dr. Suzanne Cassel, an allergist-immunologist researcher at Cedar Sinai, “People with allergies and asthma often have chronically inflamed airways, which makes them very sensitive to irritants like smoke… They may experience worsening of their allergic symptoms or develop an asthma attack even to low levels of environmental smoke.”
