Climate change is making the wet areas of the world wetter, and the dry areas of the world drier. This is pushing the climate into extremes as more natural disasters dominate the landscape. In California, this means an increase in the number of droughts and wildfires, according to the Union of Concerned Scientists (UCS).
The strong winds fueling the wildfires in Sonoma County and southern California are caused by the movement of jet streams — or the westernly air currents encircling the globe — as they pass from Canada and Alaska to the Mountain West. Low-pressure areas will land in Colorado, while high-pressure areas are drawn towards California and the Great Basin.
On their journey across the terrain, the winds gain speed. According to the Washington Post, the winds dry out the air from the mountain peaks, which makes it easier for wildfires to both start and spread. Climate change contributes to the speed of these winds.
In a study by John. T Abatzoglou and A. Park Williams on the impact climate change had on recent wildfires in the western U.S., it was concluded that the human impact on fuel aridity, or the lack of moisture in the environment, “approximately doubled the western U.S. forest fire area beyond that expected from natural climate variability alone during 1984 to 2015.”
Although climate change is not the direct cause of these wildfires, it is making their impact more extreme.
A similar study conducted by Brian J. Harvey stated that although wildfires are a natural occurrence that can, in fact, stimulate the growth of the environment, there may be negative consequences that come with the rise in their frequency. One being that it “may erode forest resilience over wide regions, threatening ecosystems, livelihoods, and communities.”
Since the 1980s, the length of the wildfire season has increased by 74 days, according to Science Magazine.
Last year’s Camp Fire killed 86 people and destroyed 90% of the town of Paradise in Butte County. Over 27,000 people were forced to evacuate the area at the time.
“The Camp Fire destroyed 14,000 structures; 11,500 of them were houses. About 90% of our homes and 50% of our commercial space were burned down. There was debris everywhere, and it looked like a warzone,” Jones said.
Jones was the mayor before and after the tragedy, and she attests that progress can be made.
“Paradise is like night-and-day since then. We had a huge debris removal program, and it’s all been hauled off,” Jones said. “We’ve issued over 300 building permits, and 11 people who have already finished their houses have occupancy permits and are back to living in their brand new homes. We’re on track to issue 500 building permits by the end of December.”
Yet the destruction of natural resources may have a greater impact on human life over time.
Current estimates place the forests in the western U.S. as responsible for 40% of carbon sequestration in the entirety of the U.S. Carbon sequestration is the long-term storage of carbon dioxide by trees and is an important process that is key to slowing down climate change. The absence and destruction of these forests as a result of climate change may, in turn, allow for an increase in carbon in the atmosphere.
Carbon dioxide has been steadily increasing in the atmosphere for several decades, and speeds up the process of climate change by trapping heat and raising the Earth’s overall temperature. According to the National Oceanic and Atmospheric Administration (NOAA), carbon dioxide is responsible for two-thirds of the energy imbalance causing global warming today.
Preventing these wildfires has tangible significance. For Paradise, improving fire safety takes on many forms.
According to Jones, the state of California adopted the Wildlife Urban Interface (WUI) design standards in 2008 and all structures built after were more fire-resistant.
“We didn’t have a lot of buildings that were built after 2008 in town, but 51% of the ones that were survived, while only 9% of the ones built prior to those standards survived. So we know that those building standards make a difference,” Jones said.
She also described several other ordinances implemented that go beyond the WUI design standards.
“You have to have fire-resistant gutters on your house, not plastic or vinyl gutters. You have to have a five feet setback from your house from anything that’s flammable. For instance, there has to be five-foot space between your house and a wooden fence,” Jones said. “You can’t attach a wood deck to your house. We’ve banned railroad ties and instituted a defensible space ordinance.”
