Climate change made the fire worse, scientists say

Climate change was a major factor behind the hot, dry season that gave rise to a devastating LA fire, a scientific study confirmed.

This made those weather conditions about 35% more likely, according to the world season – globally recognized for its study connecting extreme weather to climate change.

The authors stated that the LA wildfire season is getting longer, while the rainfall that usually removes the blazes is reduced.

Scientists throw light on the fact that these wildfires are highly complex with many factors playing a role, but they are convinced that a warming climb is making Lai more prone to intensive fire incidents.

The prominent writer of the study, Dr. of Imperial College London, Dr. “Climate change increased the risk of disastrous LA wildfires,” Claire Barns said.

“Drought conditions are pushing more often in winter, increasing the chance to fire a strong Santa Ana during the winds that can turn small ignition into deadly inphornos.”

Santa Ana winds are strong and east-east or north-eastern winds that fly from inland California towards the coast.

About 30 people have been killed in early January and over 10,000 houses have been destroyed in rapidly spreading, destructive fire.

This new study sees what the fire-prone circumstances are called which can lead to dangerous conflict.

This is a global group, a team of researchers from the World Weather Atribution (WWA), who publishes the rapid analysis of climate -related weather events.

They use the climate model to simulate how warming has occurred from mid -19th century, which is affecting heatweaves, droughts, floods and fire.

In view of the industrial revolution, widespread burns of coal, oil and gas have operated billions of tonnes of planetary-warming gases in the atmosphere.

Acting like a blanket, these gases have since raised the temperature of about 1.2C.

By using climate models and statistical methods with real -world observations, the WWA group is capable of showing how much climate warming has affected extreme events.

In the case of LA fire, he found that hot, dry conditions expeled them, expected to be once every 17 years.

This is an increase in the possibility of about 35% compared to a world that did not experience warming.

“We really see that models show the same result that (real world) observation,” Dr. Frederic Otto, head of the head of the world season, said.

“So, in this joint index, we are quite confident about the result … We really have an indication that we can say that we can definitely tell this also, quantitatively.”

Researchers also examined other important variables, leading to wildfire including the length of the fire season.

By analyzing the weather comments, scientists found that it has increased for about 23 days since heating in the world, around 1850.

The team says that this means that dry condition and Santa Ana winds that are important for the spread of fire are rapidly overlapping.

Another major element is dry.

The dry condition in the LA region in the period from October to December is now about 2.4 times more than humans before using mass fossil fuels.

Researchers are clear that climate change increased the possibility of warm, dry conditions that gave rise to fire.

However, the author is more alert about rising temperatures and long -term fire season or short rainfall, saying that models do not show an important relationship.

Despite these reservations, the conclusion is that a hot world increased the possibilities of disastrous forest fire – such as burning more fossil fuels, those opportunities will continue to increase.

Professor Gabby Hagar, the University of Edinburgh, said, “Overall paper found that climate change has made the fire of Los Angeles a greater possibility despite some statistical uncertainty.”

“This is a careful research result that should be taken seriously,” he said in a statement.

The new work makes the research which was published while the fire was still burning fiercely.

The study called the wildfier “called” called “Climate whipplash,

The idea is that very wet years are followed by almost very dried people, which increases the risk of fire.

This happened in LA, when after two wet winters this year a very dry autumn and after winter – the wet weather promoted the growth of grass and bushes which became fuel for fire which was closed in the winds Was gone
