summary
- A new report states that the modern and dry winds that have been dried at high temperatures led to the fire in the Southern California have been about 35 % higher due to climate change.
- The survey results are from a world meteorological group that analyzes the effects of global warming on extreme events.
- The fire killed at least 29 people and destroyed more than 16,000 buildings.
The International Scientist Group has increased the extreme situation of climate change in the extreme situation that recent fires have made RO sounds in the Los Angeles area as a whole.
A strong state of dry winds at high temperatures ahead of the fire could have been about 35 % higher due to global warming caused by humans. New reports from the World Meteorological attribute groupWe analyze the effects of global warming on extreme events.
The fire, which began in the event of a fierce storm in the spring, killed at least 29 people, including houses, shops, and schools, as it had not been raining in the Great Los Angeles since spring.
“This was a perfect storm for the conditions of the fire disaster. From the viewpoint of the climate that enables the climate, the weather that drives the fire, and the huge environment from the place where these ignitions occurred.” Merced, who contributed to the report at the University of California, said at a press conference.
Compared to the time before the industrial revolution before fossil fuels were widely used, the Los Angeles area had a “dry season” on average every year, and the fire may match the seasonal Santaanana style. Is high. 。
Park Williams, a geographical professor at the University of Los Angeles, the University of California, said Park Williams in the cool season of Southern California. Unusually dry state; Ignition (almost always comes from people); and extreme weather like recent storms. He explained each of these conditions as an individual switch in a system that needs to be turned over all four to emit light.
“The artificial warming caused by climate change caused by humans makes light brighter,” said Williams.
The author in the report analyzes the weather and climate models to evaluate how the warm atmosphere changes the possibility of fire (it means a condition that increases the risk of mountain fire). They also tracked how metrics called the fire weather index changed over time. The index tracks all factors that contribute to temperature, relative humidity, wind speed, and fire.
Researchers have discovered that the types of conditions that promote the fire in the LA region are expected to occur once every 17 years in today's climate. Such a state would have been predicted once in 23 years without climate change, and it would not have been so extreme when they occurred.
