California problem now is not a fire – it’s rain

California Weather Cinelash It was a problem It dates back to centuries, or more. Fire is normal and A necessary part of the various ecosystems in CaliforniaBut the so -called “Expand the eye of the bull“One of the urban areas that spreads in quiet wildfires has led to the complexity of things.

Before human arrival in southern California, Saford is estimated, the average toilets may go from 30 to 90 years without a huge fire. With the addition of 20 million people and climate change, “some places in Socal burn every two years to 10 years so far.”

At this pace, wooden bushes cannot grow enough quickly after fire, and the frequency of the growing fire pushes the area to a transition from the Chapherral and Ok forests to Herbal lands In some cases, bare soil. When ecological systems lose the cover of leaves and deep roots, it makes it easier for the slipping soil.

Recently, it was much worse. These days, southern California fluctuates between wet and dry systems as soon as the Beyonce tour is the lowest. During the past few months, southern California quickly It decreased in severe drought Immediately after two years of the most moisture ever. This motivated a significant growth in the vegetation and then dried it quickly: the perfect recipe for hot and irreplaceable fire – and debris flows to follow.

“At the same time,” says Fayh Kearns expert, at the same time, “at the same time, at the same time, the forest fires themselves also burn more, leaving behind the soil affected by the fire and that which is that You can block water and a little vegetation to keep the slopes intact. “

Completely, Palisades and Eaton Fires killed 29 people, destroyed more than 16,000 homes, and produced an economic impact About 10 times greater than any previous catastrophic disaster in California history. Etone fire, near Pasadina, and Palisades, near Malibu, Now ranking As the second and third destructive fires in the history of California, after 2018 Camp fire Which destroyed the city of Paradise.

Fire systems It changes all over the worldAnd when the agent is the deterioration of the health of the forests More rainy storms, This leads to a much larger frequency of debris flows after shooting in the areas where they occurred in the past. In reality, A recent study He showed that “by the end of the twenty -first century, it is estimated that the activity of the flow of debris after the shooting increases in 68 percent of the areas where it occurred in the past and a decrease in only 2 percent of the sites.”

The main driver here, according to Luke McGoer, a geologist at Arizona University and the author of this study, is not so much that the rain is more exciting – it does not require much rain to start the flow of debris – but that fires get worse.

“If climatic changes lead to a greater possibility of medium to highly popular fire, this would increase the possibility of the flow of debris after the shooting by creating the conditions that feed them frequently,” says McGoire.

In California, fires have definitely become more intense in recent years.

Thirteen of the 20 largest fires occurred in California during the past century In the past seven years only. These seven years include three of the most dry and two of the most moistures in the history of the country.

Data shows that this problem is not limited to California. “The fire activity is expected to increase in many parts of the western United States, which can push increases in the possibility of harmful debris,” McGoire says.

As the planet continues to turn into a hotter version, vulnerable to drought, hills will be increasingly collapse into the valleys below where the fires occur. It is an inevitable result of the speed with which geological changes occur in human time schedules.
