Russian Siberian Yakuts Known as the coldest city in the world.. I’m used to paying attention to sub-zero temperatures, such as spending extra time changing layers in the morning, where the nose can be painful and painful during the winter months.
But now the city is covered in haze Like a nearby wildfire cut through the forest It has been dried up by the heat waves that lasted for weeks. The fire is very big, the wind is strong, and the smoke is flowing far to Alaska.
In the United States, Oregon’s bootleg wildfire has grown into a huge complex In its own weather, Sends about 3,000 miles of heavy smoke from one end of the continent to the other. Wednesday New York City I woke up to a bright red sunrise, the smell of a wildfire, and a dark brown haze.
Firefighters from both countries and British Columbia, Canada, are fighting an almost impossible battle to suffocate Inferno with water bombs and hoses, and digging firebreaks to prevent its spread.
The smoke in the Republic of Yuktia in Siberia was so thick on Tuesday that reconnaissance pilot Sviatoslav Kolesov was unable to do his job. There was no way to fly an airplane with poor visibility.
Kolesov is a senior aeronautical observation post-pilot in the Yakut region of the Russian Far East. This region of Siberia is prone to wildfires and most of the region is covered with forests. But Kolesov told CNN that this year’s flames are different.
“A new fire broke out in the north of Yakut, where there was no fire last year and it never burned before,” he said.
Kolesov sees first-hand what scientists have warned for years. Wildfires are getting bigger, more intense, and even in unfamiliar places.
Thomas Smith, an assistant professor of environmental geography at the London School of Economics, said:
Many factors, such as poor land management, affect wildfires, but climate change makes them more frequent and violent. Most of Europe, Western United States, Southwestern Canada According to the Copernicus Climate Change Service, some parts of South America became drier than average in June, creating a forest tinderbox.
Yakut wildfires have consumed more than 6.5 million acres since the beginning of the year, according to figures released by the national aerial forest protection service. It’s almost 5 million football fields.
In Oregon, eight fires have burned nearly 475,000 acres so far. During the fire season, officials said there was an unprecedented fire. Bootleg Fire is so large that it produces so much energy and extreme heat that Create your own clouds And thunderstorms.
British Columbia, Canada, has declared an emergency after a wildfire broke out on Wednesday. Nearly 300 active wildfires have been reported in the state.
Wildfires are part of a virtuous circle. Not only are climate change causing fires, but their burning releases more carbon into the atmosphere, which exacerbates the crisis.
Some scientists say this year’s fire is particularly terrible.
Mark Parrington, Senior Scientist at Copernicus Atmospheric Monitoring Services, said:
He said Yakut has been experiencing continuous high-intensity fires since the last few days of June.
“If you look at the timeline, you’ll see the same level of intensity, but not three weeks, but I think the longest one in the past was probably two weeks or ten days, or something like that. More isolated. The fire season usually lasts until mid-August, so the fire is likely to continue, he added.
More frequent and more intense
According to Smith, wildfires are constantly occurring in Siberia and parts of Canada, but the concern is that the fires are very frequent.
“Once upon a time, there was a fire in one place every 100 to 150 years, which means that the forest is completely regenerated, becomes a mature forest, a fire breaks out, and the fire starts again,” he said. .. ..
“In some parts of Eastern Siberia, fires occur every 10 to 30 years in some places, which means that forests can no longer mature and eventually [ecosystem] Shift to a kind of shrubland or wetland grassland. “
Heat waves and droughts also make new areas vulnerable to fire.
“In the Siberian Arctic, we are worried about the tundra ecosystem north of the forest, which is usually too moist or frozen to burn,” Smith says. “In the last two years, there have been many fires in this ecosystem, which suggests that things are changing.”
It also has serious and long-term consequences for the climate. Ash from fire can also accelerate global warming by darkening the surface, which is usually light in color and reflects more solar radiation.
Areas affected by these fires also include flark, one of the most effective carbon sinks on the planet, Parrington said.
“If they’re burning, it’s emitting carbon,” Parrington said. “It’s about getting rid of the carbon storage system that’s been there for thousands of years, so there’s a potential knock-on effect.”
