California wildfires: Everything we know and how you can help

September 10, 2020 John Mendoza No Comments

An unprecedented fire season is wreaking havoc across the West, with wildfires tearing across multiple states and air quality plummeting. At least 10 people have been killed and over 3,000 homes destroyed since the season began. California’s wildfires, driven by extreme blazes in August and September, have already burned more acres than any year on record. In a sign of things to come, the fire season is yet to peak, and fires have broken out in both Oregon and Washington. The images and stories coming out of the US west are eerily reminiscent of those experienced by Australians in early 2020.

In January, vast swaths of Australia burned. The skies turned orange, and smoke blanketed the country’s largest cities. Entire cities were flattened. Now, across the Pacific, this grim history is repeating. San Francisco has turned red and orange, smoke blotting out the sun. In Oregon, hundred of homes have been lost to growing wildfires. In only 24 hours, more of Washington state burned than in 12 of the previous 18 fire seasons. 

Here’s what we know about the ongoing fires and how you can help from the US or afar.

What caused the fires?

Fires can start in a variety of ways. Human activity, like carelessly discarding a cigarette, poorly maintained infrastructure or even gender reveal parties with pyrotechnics can spark fires. Some of the wildfires currently blazing across California are the result of accidental ignition. Fires can also be deliberately lit, though arson has not been linked to the current conflagrations.

Nature also conspires to begin fires, with lightning strikes a major concern. In California, intense thunderstorms kicked off a number of large blazes in August. Prolonged periods of drought and mismanagement of national parks may also play a role in helping these fires start. With the fire season getting longer, the window to perform critical hazard reduction burns has decreased, giving fires a chance to really take hold. The risk of the wildfires burning across western US was well-known to scientists and, regardless of the origins, fires are fueled by a dizzying number of factors.

A lack of rain and low soil moisture can help enable small fires to grow in size, and coupled with the high temperatures and fierce winds, small fires can quickly become huge infernos. This all feels extremely similar to anyone familiar with the bushfire crisis confronted by Australia in January. Environmental factors contributed significantly to the unprecedented fire season down under and they are playing out again in the US — partially driven by the negative effects of climate change.

What is the connection to climate change?

Wildfires aren’t started by climate change, but they are exacerbated by the effects of global warming. The Climate Council, an independent, community-funded climate organization, suggests fire conditions are now more dangerous than they were in the past, with longer bushfire seasons, drought, drier fuels and soils, and record-breaking heat in Australia. The link between fires and climate change has become a political football, but experts agree climate change explains the unprecedented nature of the current crisis. 

Wildfires are getting worse in the US. According to data from the Monitoring Trends in Burn Severity program, on average, there are more wildfires, and they are burning more land each year. A study published in July 2019 concluded that “human-caused warming has already significantly enhanced wildfire activity in California… and will likely continue to do so in the coming decades.”

There’s no question that 2020 will be one of the hottest years on record for the planet, and a 75% chance it will be the hottest ever, according to a report by the National Oceanic and Atmospheric Administration. Increased temperatures allow fires to burn more intensely and also cause forests to dry out and burn more easily. The heating is unequivocally caused by climate change. 

On Sept. 9, California Gov. Gavin Newsom tweeted a short video by Bloomberg’s QuickTake in which he said “climate change has profoundly impacted the reality that we’re currently experiencing.”

There is also a horrifying feedback loop that occurs when great swaths of land are ablaze, a fact the globe grappled with during the Amazon fires of 2019 and the Australian bushfires of 2020. Huge fires release large amounts of carbon dioxide, a greenhouse gas, into the atmosphere. The gas, which makes up only a small percentage of the total gases in the atmosphere, is exceptionally good at trapping heat. 

Andrew Sullivan, a fire research team leader for CSIRO, an Australian government research agency, examined how technology may help predict and fight against fires. In September, he told CNET that “changes to the climate are exposing more areas to the likelihood of fire.” 

What areas are affected?

Fires are burning across the western US, but the greatest conflagrations are across California and Oregon. 

More than 2.5 million acres have burned in California, with over 2,500 more fires than at the same point in 2019. One of the largest fires during the Australian season, the Gospers mountain megafire, burnt through around 2.2 million acres. “Unprecedented” is the word again being used by officials, weather services and media to describe the size and severity of the blazes. The dust and ash from the fires have turned the skies orange across California.

Blazes in Oregon have been increasingly destructive, driven by heavy winds. “I want to be upfront in saying that we expect to see a great deal of loss, both in structures and human lives,” Oregon Gov. Kate Brown said during a briefing Tuesday. “This could be the greatest loss of human lives and property due to wildfire in our state’s history.” 

Washington has also experienced significant fires, with almost 350,000 acres burned in a 24-hour period in early September. Two large fires broke out on Sept. 8, and Gov. Jay Inslee said “more acres burned … than in 12 of the last 18 entire fire seasons in the state of Washington.”

The New York Times has an informative fire map that can help you track where conflagrations are burning.

Do I need to wear a mask?

The smoke and ash from wildfires can irritate the respiratory tract and make it harder to breathe. During Australia’s bushfire season, there was a stark increase in the amount of calls to ambulance services and researchers have demonstrated there may be a significant health burden on those exposed to smoke. Respiratory distress sees more people entering hospitals in the US during a typical wildfire season.

Fine particles in the air can cause damage to the lungs and increase inflammation in the short-term. What is less certain is the long-term effects of exposure to smoke.

We have become intimately familiar with the use of masks over the last six months, thanks to the coronavirus pandemic, but you may be wondering whether you need to use one to protect against smoke from wildfires. The short answer is: You probably should, but filtering smoke and ash out of the air requires an N95 or P100 mask — and public health officials suggest these should be reserved for health care workers. They also cannot completely filter out some of the gases present in wildfire smoke. 

Cloth masks and other coverings we have become familiar with during the pandemic will not be effective at protecting against smoke. The US Environmental Protection Agency says remaining indoors and limiting your time outdoors is “the most effective way” to protect yourself during wildfire emergencies.
