Climate change eliminates the time of the natural process. Scientists have proof that flowers are opening, trees are falling their leaves, and animals are emerging from hybrids than years ago.
“We’re seeing the trend towards the beginning.”
Now, there is new evidence of another climate shift: California’s forest fire season begins 46 days before the normal start of 3 decades. Analysis, which appeared in a paper Science developmentFor, for, for,. It was learned that this trend was the same in various California’s ecosystem.
In this study, the beginning of the jungle fire season was explained like the day when 5 % of this season was set on fire. “We’re looking at the trend towards the beginning of the previous start,” said Gwen de Madakombora, a hydrochimatologist at the University of California, Los Angeles, Los Angeles and the main author of the new research. “We wanted to understand what the reason was.”
In the previous work, including a historic 2006 study, indicated that in some Western American forests, the forest fire season has both longer and has begun before.
In order to correct the role of climate change in these trends, Madikumbora and his colleagues first analyzed the presence of fire in the service of the US forests and the date of the Season Start Dates, from 1992 to 2020, from the mountains of the north to the south, from the mountains of the north to the south. He found that since 1992, the fire season has begun before a hegemony (Sonoran Basin and Range). The coschen Ekurgeon moved the most, 46 days ago compared to the 2020 start of 1992.
“The fact that they can see [the shift] Carvers, most of which are important in terms of a wide range of environmental systems, are important, “said Leroy Westerling, a climate scientist at the University of California, Merced, who was the main author of the 2006 study that had previously indicated the change.
Although the beginning of the time has been suspected for years, its intensity is much larger than expected and “really amazing”, “the University of Colorado Bolder’s climate scientist, Virginia Eglasius, who was not involved in new research, was in an email.
The Northern California Environment showed strong trends than the southern Equisers, in which East Caskads, Caskyads, Central California’s footsteps, and coastal mountains showed significant changes. Madakumbora said that there is a difference in the North-Jubilee because the northern environment fire is more sensitive to the changes in winter snacks, which is even less due to climate war.
The role of climate change
The team then reviewed the role of climate change, such as the driver of the dates for the beginning of the weather for each of the Evargen.
Each of the one, they, decided how strong the climate drivers, such as dry fuel, were firmly, compared to drivers who did not directly related to climate change, such as plants type. Then over time, they compared the changes made for each of these drivers.
“Divine -based limits that we have long relied on to prepare for fire can no longer live.”
As a result, it has been suggested that although the natural change and severe drought in mid -2010 played a vital role in pre -fire seasons, the climate change was a major driver of the previous season in 11 of the 11 of the 13.
“The rest of the climate and fuel is the main factor of control,” said Madakumbora.
“This article provides compulsive evidence in this article that the changing of anthropic climate is a dominant and viable driver of the pre -jungle fire,” said Egsius. “The logic is clear and the results are well supported.”
The authors have written that since the climate is hot, the chances of a fire season in California will also start already. Knowing the trend of fire seasons trends, Madakumbora said, knowing that emergency managers could help prepare for long -term fire seasons, which burn more and more area.
Westerling said, “An initial start of the season imposes taxes on all the resources that were long ago.” “This is the same people, the same goods, and the same budget that is under pressure.” He said that the fire season in California is spreading in the fall later, he said, adding that the communities need to be prepared for the fire.
The contradictions between the North and South Trends wrote, highlighting the need for a regionally prepared fire management and climate adaptation strategy.
“Divine -based limits that we have long relied on to prepare for fire can no longer live.”
