California’s issues are no longer fire now. It’s raining
California Weather whiplash There was a problem Going back centuries. Fire is natural, Necessary parts of California’s diverse ecosystemsHowever, the so-called “Enlarge the BullseyeThe urban areas that spread across major urban wildfire zones are complex.
Safford estimates that the average fork could be between 30 and 90 years without wildfires before a human arrives in Southern California. With 20 million people and the addition of climate change, “Some places in SOCAL are currently burning every two to ten years.”
At that pace, woody shrubs are unable to regrow enough fast after fire, and the frequency of fires is increasing, causing the area to be forced into a transition from Chaparal and Oak forests. Grassland And in some cases, bare soil. When the ecosystem loses leaf covering and deep roots, the soil becomes more likely to slip downhill.
Recently, that’s gotten even worse. Recently, Southern California vibrates between wet and dry regimes almost as fast as Beyoncé’s latest tour sold out. Over the past few months, Southern California is soon A serious drought has entered Two years after the westest year on record. It spurred sufficient vegetation growth and quickly dried. The perfect recipe for hot, destructive, uncontrollable fire, followed by the shards.
“The risk of damaging debris flow after a fire increases as the climate changes, as seeing strong storms during stronger drying times leads to instability in previously burned areas. Because it’s possible,” Arizona State University. “At the same time, the wildfire itself is burning more vigorously, leaving behind fire-affected soil that can repel water and less vegetation to keep the slopes intact.”
The January Palisade and Eton fire combined to kill 29 people, destroying more than 16,000 homes, creating economic impact Approximately 10 times larger than previous wildfire disasters in California history. Eton Fire near Pasadena and Palisade Fire near Malibu; Now rank Since 2018, it has been the second and third most destructive wildfire in California history. Camping fire It destroyed the town of paradise.
Fire regime It’s changing all over the worldand when considering the deterioration of forest health and More intense storms, It is much more frequent in areas that have happened in the past, post-fire debris flows. in fact, Recent research “By the second half of the 21st century, post-launch debris flow activity is estimated to increase in 68% of past occurrence areas and decrease only at 2% of locations.”
The main driver here is not so heavy rainfall, according to Luke McGuire, the University of Arizona geoscientist and the lead author of the study. It doesn’t rain much to begin the wreckage flow, but the fire is getting worse.
“The chances of moderate to high-intensity fires increase, McGuire said:
And in California, fires have become even stronger in recent years.
13 of the 20 biggest fires in California over the past century Over the past seven years. These seven years include the driest three and two of the state’s history.
The data shows that this issue is not limited to California. “Fire activity is projected to increase in many parts of the western United States,” McGuire said.
As the planet continues to move towards a hotter, more drought-prone version, Hills Ride begins to crumble more and more into the valley below when a fire occurs. This is an inevitable consequence of the speed at which changes in geological scale are currently occurring in human timelines.
