Editor’s note: As wildfires came dangerously close to Sequoia and Kings Canyon National Parks in September 2020, the curator of the archives there worked with Emily Lin, librarian and head of digital curation at the University of California Merced, to evacuate the archives to keep them safe. In this interview, Lin explains how they evacuated the records, what’s in them and why they’re worth preserving.

Listen to Emily Lin of UC Merced talk about the archives and see the contents of the park archives and photos from the evacuation.

Why were the archives of Sequoia and King’s Canyon National Parks evacuated?

Ward Eldredge, the curator of the archives of the Sequoia and Kings Canyon National Parks, and I had been talking about the potential partnership around digitization of collections that had been housed there for a couple of years now. There’s been a concern about the safety of these records because wildfires in the past few years have been an annual threat. So the long-term safekeeping of the records was very much on Eldredge’s mind. And he pointed out that the UC Merced campus is located in one of the few areas in California that are outside of a high-risk fire zone and also outside of the risk of earthquakes. There was just no question that we would do whatever we could to bring them here for safekeeping.

In September, when the fires got really close to the park, Eldredge was trying really hard to find a way to move the materials. He just couldn’t find a van or a truck because the residents in the area were also being called to evacuate, and there was a shortage. So in the course of a day, we managed to make arrangements to take our moving truck from campus, and he was able to secure a U-Haul truck. We were able to pack everything and move it out of the mountains to the UC Merced campus, which is two and a half hours away.

What’s in these archives?

There were hundreds of boxes of collections, about 600 linear feet, and also cabinets of plant specimens and artifacts.

It’s a complete record of the administrative history of the park. Sequoia was the second-oldest national park in the U.S., established in 1890. So there are records related to its founding and through to the 20th century. In letters written by the park directors to the U.S. president and the secretaries of the Department of the Interior, one can see how the thinking around managing public lands, conservation, fire and forest management changed over the last century.

Before the park was established, people would cut the sequoias down for timber. The city of Los Angeles wanted to build a dam in Kings Canyon up until 1965. So you can see how the thinking changed and how we got from that way of thinking to really establishing the National Park Service and protecting these unique environments.

There’s an incredible photographic record – tens of thousands of photographs that cover pretty much every place within the park. There are maps of the sequoia groves, maps related to how trails and roads and other buildings were constructed. We take these trails for granted, but they were huge undertakings involving hundreds of workers breaking rocks, cutting trees and excavating for years. They worked through the winter sometimes to do it within schedule. These projects also provided jobs during the Great Depression.

Who will find them useful?

Anyone, from those within the parks who want to better understand the history of the park, to the rangers and the interpreters who want to provide and present that history to the general public. Ken Burns, the acclaimed documentary filmmaker, accessed these records while he was making his television series about the national parks.

They’ll also be more widely available for students to use. There’s plenty of material in there for lots of Ph.D. students working on dissertations and for those who want to really investigate how best to manage public lands and determine what’s effective. That knowledge is going to benefit the broader public and help conserve these national parks for all of us. There’s a rich record that can help us understand what is unique about the environment that allows these trees to survive.

What are the plans for keeping the archives at UC Merced?

When the records were kept in the park, it was just one person, Ward Eldredge, maintaining the records. That’s a lot of work. You could make an appointment and he could provide access if you wanted to come to the park, but it’s in a very small space within the park headquarters, so the accessibility was definitely limited. Now that these collections are at the library at UC Merced, it will be easier for people to be able to access them.

Our vision is to be able to digitize much of this material. Once it’s online, it will be a lot easier for people to at least see and maybe answer some of their immediate questions. And if there’s a need for them to see the physical material, they can still make arrangements to do that.

There’s still a long way to go, because normally, we would have to make a plan with the National Park Service, raise funds, build the facilities to store them safely and so on. Because we had to evacuate them, we still have to work on formalizing an agreement, but our goal is eventually to make sure that these records will be safe.

Western Wildfires Are Spinning Off Tornadoes – Here’s How Fires Create Their Own Freakish Weather

It might sound like a bad movie, but extreme wildfires can create their own weather – including fire tornadoes.

It happened in California as a heat wave helped to fuel hundreds of wildfires across the region, many of them sparked by lightning. One fiery funnel cloud on Aug. 15 was so powerful, the National Weather Service issued what’s believed to be its first fire tornado warning.

So, what has to happen for a wildfire to get so extreme that it spins off tornadoes?

As professors who study wildfires and weather, we can offer some insights.

How Extreme Fire Conditions Form

Fires have three basic elements: heat, fuel and oxygen.

In a wildland fire, a heat source ignites the fire. Sometimes that ignition source is a car or power line or, as the West saw in mid-August, lightning strikes. Oxygen then reacts with dry vegetation to produce heat, ash and gases. How dry the landscape is determines whether the fire starts, how fast it burns and how hot the fire can get. It’s almost as important as wind.

Fire weather conditions get extreme when high temperatures, low humidity and strong winds combine with dead and live vegetation to produce difficult-to-fight, fast-spreading wildfires.

That combination is exactly what the West has been seeing. A wet winter fed the growth of grasses that now cover large areas of wildland in the western U.S. Most of this grass is now dead from the summer heat. Combined with other types of vegetation, that leaves lots of fuel for the wildfires to burn.

The remnants of Hurricane Elida also played a role. The storm increased moisture and instability in the atmosphere, which triggered thunderstorms further north. The atmosphere over land was pretty dry by then, and even when rain formed at the base of these clouds, it mostly evaporated due to the excessive heat. This led to “dry lightning” that ignited wildfires.

Wildfires Can Fuel Thunderstorms

Fires can also cause convection – hot air rises, and it moves water vapor, gases and aerosols upward.

Wildfires with turbulent plumes can produce a “cumulus” type of cloud, known as pyrocumulus or pyrocumulonimbus. Pyrocumulus clouds are similar to the cumulus clouds people are used to seeing. They develop when hot air carries moisture from plants, soil and air upward, where it cools and condenses. The centers of these “pyroclouds” have strong rising air.

It’s pretty common, and it’s a warning sign that firefighters could be facing erratic and dangerous conditions on the ground from the indraft of air toward the center of the blaze.

In some cases, the pyroclouds can reach 30,000 feet and produce lightning. There is evidence that pyrocumulus lightning may have ignited new blazes during the devastating fire storm in Australia in 2009 known as “Black Friday.”

Where do fire tornadoes come from?

Similar to the way cumulonimbus clouds produce tornadoes, these pyroclouds can produce fire‐generated vortices of ash, smoke and often flames that can get destructive.

A vortex can form because of the intense heat of the fire in an environment with strong winds. This is similar to a strong river flow passing through a depression. The sudden change in the speed of the flow will force the flow to rotate. Similarly, the heat generated by the fire creates a low pressure, and in an environment with strong winds, this process results in the formation of a vortex.

One fire tornado, or fire whirl, that developed during the deadly 2018 Carr Fire devastated parts of Redding, California, with winds clocked at over 143 miles per hour.

These vortices can also increase the severity of the fires themselves by sucking air rich in oxygen toward the center of the vortex. The hotter the fire, the higher the probability of stronger updrafts and stronger and larger vortices.

Persistent heat waves that dry out the land and vegetation have increased the potential of wildfires to be more violent and widespread.

Is extreme fire weather becoming more common?

Global warming has modified the Earth’s climate in ways that profoundly affect the behavior of wildfires.

Scientific evidence suggests that the severity of prolonged droughts and heat waves has been exacerbated not only by rising temperatures but also by changes in atmospheric circulation patterns associated with recent climate change. These changes can enhance extreme fire-weather behavior.

A study published Aug. 20 found that the frequency of California’s extreme fire weather days in the autumn fire season had more than doubled since the early 1980s. Over that four-decade period, autumn temperatures in the state rose by about 1.8 degrees Fahrenheit and autumn precipitation decreased by about 30%.

Firefighters and people living in wildfire-prone areas, meanwhile, need to be prepared for more extreme wildfires in the coming years.

More Than 260 Major, Mostly Illegal Amazon Fires Detected Since Late May

The Amazon Fire Season is Building Momentum

Article originally appeared in Mongabay.com, by Liz Kimbrough on August 13, 2020 (CC BY-ND 4.0)

  • The Amazon fire season is building momentum, with 227 fires covering nearly 128,000 hectares, reported between May 28 and August 10. By today, that number rose to 266 fires.
  • More than 220 of the May 28 to June 10 fires occurred in Brazil, with just six in Bolivia, and one in Peru. 95% of the Brazilian fires were illegal and in violation of the nation’s 120-day ban on fires. Brazilian President Jair Bolsonaro has called the 2020 reports of deforestation and fires a “lie.”
  • Most Amazon blazes are set, with land grabbers, ranchers and farmers using fire as a deforestation tool, and as a means of converting rainforest to pasture and croplands.
  • Fourteen of the Brazilian fires were within protected areas. The most heavily impacted of these were Jamanxim and Altamira national forests in Pará state — areas long notorious for criminal land grabbing.
This natural-color image of smoke and fires in several states within Brazil including Amazonas, Mato Grosso, and Rondônia was collected by NOAA/NASA's Suomi NPP using the VIIRS (Visible Infrared Imaging Radiometer Suite) instrument on August 20, 2019. Although it is not unusual to see fires in Brazil at this time of year due to high temperatures and low humidity it seems this year the number of fires may be record setting. According to Brazil’s space research center INPE almost 73,000 fires have been recorded so far this year. INPE is seeing an 83% increase over the same period in 2018. NASA's Earth Observing System Data and Information System (EOSDIS) Worldview application provides the capability to interactively browse over 700 global, full-resolution satellite imagery layers and then download the underlying data. Many of the available imagery layers are updated within three hours of observation, essentially showing the entire Earth as it looks "right now.” Suomi NPP is managed by NASA and NOAA.

A total of 227 fires covering 127,866 hectares (315,963 acres) — an area nearly twice as large as New York City — were reported between May 28 and August 10. The number of fires is increasing as the region enters the peak fire season, according to an analysis of satellite data by the Monitoring of the Andean Amazon Project (MAAP).

As of today, August 13, that number has risen to 266 fires.

More than 220 of those observed between May 28 and August 10 occurred in Brazil, with just six in Bolivia and one in Peru. Over 95% of the Brazilian blazes were illegal, violating the nation’s 120 day fire ban enacted by President Jair Bolsonaro on July 15. The illegal blazes are occurring despite the advance deployment of the Brazilian Army to the Amazon in May to prevent fires being set.

Major fires in Brazil in 2020

Fire data from MAAP’s Amazon Fire Monitoring App is up to date through August 11, 2020

Only two of the reported blazes were confirmed forest fires, covering 1,447 hectares (388 acres) in Brazil. The rest took place on lands cleared of forest in the past two years, underscoring the significance of deforestation as a catalyst for fire in the Amazon.

“We argue that the central issue is actually deforestation and [that] the fires are actually a smoking indicator of this forest loss,” the report states.

The Amazon fires that garnered international attention in 2019 were not acts of nature, but generally followed a pattern of deforestation, with the blazes set by farmers, landowners and land grabbers as a means to convert cleared forests into pasture and croplands.

Last year, MAAP analyzed archived satellite imagery from Planet Explorer, and discovered that many of 2019’s fires burned areas deforested earlier that same year. Based on that finding, MAAP predicted 2020 fire locations would follow suit, occurring in areas that saw major deforestation earlier this year. Currently, four of the seven areas MAAP predicted would burn in 2020 have, according to Matt Finer, senior research specialist and director of MAAP.

This week, President Bolsonaro denied both this year’s fires and 2020 deforestation in remarks during the second Presidential Summit of the Letícia Pact for the Amazon. “There is no fire outbreak, not a quarter of a hectare was deforested,” Bolsonaro said. “It is a lie, this story that the Amazon burns with fire.”

The latest data released by INPE, the country’s National Institute for Space Research, found that 9,205 square kilometers — an area about eleven-and-a-half times as big as New York City — were deforested in the Brazilian Amazon over the past 12 months, an increase of 34.5% over the comparative period in the previous year. The official annual estimate of deforestation between August 1, 2019 and July 31, 2020 is expected to top 11,000 square kilometers when it is released this fall.

MAAP monitors fires in the Amazon in near real time, using the Real-time Amazon Fire Monitoring app to pinpoint areas with elevated aerosol emissions, caused by large amounts of biomass burning. A “major fire” is defined as one with an aerosol index of  >1 (appearing cyan-green to red on the app). Once an alert is detected, MAAP analyzes high resolution satellite imagery to confirm the fire. MAAP also compares satellite imagery from year to year to determine if the fire broke out following a recent deforestation event. This measure is different than the widely reported “hotspots” from satellites, which already number in the tens of thousands this dry season.

“We go two steps further than the commonly reported (and often misleading in my opinion) heat-based alerts, to much more precisely track major fires,” Finer said.

Both NASA and INPE, Brazil’s national space research institute, use satellites with infrared “heat-sensing” technology to detect hotspots. These may have a limited capacity to detect smaller fires and sub-canopy fires, which can be substantial in tropical forests.

In Brazil, 14 of the reported 2020 fires arose within protected areas. The most heavily impacted are the Jamanxim and Altamira National Forests in Pará state — conserved areas notorious for criminal land grabbing and illegal deforestation.

The Jamanxim National Forest was hard hit by deforestation in 2019, losing more than 3% of its forest cover in May 2019 alone. Those living in the area say Bolsonaro’s anti-environment rhetoric has emboldened land speculators and loggers to clear the protected lands and sell the property to ranchers at inflated rates. While sometimes prosecuted for these violations, most law breakers never pay their fines, and the government — under the Temer and Bolsonaro administrations — periodically has issued or urged amnesties to illegal deforesters and land grabbers.

The Altamira National Forests, home to the giant otter (Pteronura brasiliensis), Amazonian manatee (Trichechus inunguis), and the jaguar (Panthera onca), saw an 85% rise in deforestation in 2019 over the prior year. Illegal tin mining, gold mining, logging, and cattle ranching have escalated deforestation in the protected area.

“We emphasize, however, that these fires [in Jamanxim and Altamira National Forests] were burning recently deforested areas, not [naturally occurring] forest fires,” says the MAAP report, “and so, again, the primary issue is deforestation.”
