The second year, an unusually large number of intense fire ignited in the Arctic Circle, the Arctic region on Earth.

It has now been anomalously warm in Siberia for nearly six months, the temperature may more than triple the number in the Siberian city last weekend—set a heat record for the Arctic Circle. This streak of warm and hot conditions for the fires of the torch to dry the area. Last year, unprecedented fires burned in the Arctic Circle, and the new data from Copernicus, the European Earth observation mechanism, Show that the number and intensity of fires is similar in 2020.

The robust fire was a problem, because burning forests and vegetation release large amounts of heat-trapping greenhouse gases(CO2,for example, is a major ingredient in the smoke), especially when thick mats of the decomposition of carbon-rich vegetation, the so-called peat, and ignited. 18 years the researchers used satellites to monitor closely the Arctic Fire, 2019 and 2020 have been issued more CO2 into the atmosphere than In the past 16 years of combinedSaid Thomas Smith, assistant Professor in Environmental Geography at the London School of Economics.

“Two years together, is quite amazing,”said Smith. “I wouldn’t use the word lightly.”

In just six weeks last year, Arctic Fire releasing more into the atmosphere of carbon dioxide, than in Sweden and in the whole year, According to the World Meteorological Organization.

As Earth’s climate continues to relentlessly warm, the recent fire may be a harbinger of substantially more combustion in the Arctic Circle. However, the 18-year wildfire in the satellite record(beginning by a NASA satellite in 2002)is still too short, to end sure, the most recent of these fire years of evidence that the fire regime in the Arctic has dramatically changed. Still, there is growing evidence that change is in the forests and tundra on.

“Have confidence, we can say that this does appear to be an increasing trend of the fire,”said Jessica McCarty, an Arctic Fire researcher and assistant Professor in the Department of geography at the University of Miami. “There are some shift happens.”

She stressed that recent fire activity in the local area”is an interesting finding,”but it will take years of further observation to confirm, if it’s part of a larger, ongoing trends. Fire season is naturally cyclical, which means there may be fire years later by a less intense period of Landscape Restoration and vegetation will regrow in addition, Siberia has killed the atypical warm temperatures, almost six months. Some years will inevitably be cooler, which may mean less favorable conditions for the flame.

There is a diversity of ecosystem combustion in the Arctic right now, according to the Analysis, by Smith, Including forested areas, shrubs and tundra. It is important that the ground in some of the burned peat areas(although it is difficult to accurately estimate how much), which means that the ancient, thick deposits of carbon combustion and the release of the potent greenhouse gas carbon dioxide and methane into the air.

This adds more heat to the captured gas to an atmosphere that already contained in the At least There are 800 000 years, but more likely millions of years.

“You lose the carbon storage,”Smith said. “This is a thousand years of history. If we consider climate change, it will need thousands of years of carbon accumulation(soil and vegetation) are.”

An important takeaway from the last two extreme years of the Arctic region the fire is not there must be such a strong fire season each summer, but now it’s not off the warming of the environmental conditions allow this atypical combustion is possible, or more possible. “We do not expect these fires all the time,”said McCarty. “But we know the landscape, you can burn.”

In the spring, some of the 2020 Arctic Fire might have been zombies a fire or maintain a fire, which survive underground during the winter and then re-appear the following year. But overall, about 85% to 95%of the fire are lit humans, either intentionally or unintentionally, explained McCarty. While the lightning strike is often the beginning of the largest Arctic region of the fire, she said, as the region warms and the air becomes more humid in the summer, the polar regions can see more of lightning.

“In the future, we hope to have more lightning strike in the Arctic in a warming climate, and therefore the more potential of the Arctic region of the fire,”said McCarty.

There will be more combustion in the Arctic Circle this summer, as a stagnant warm weather pattern continues hot areas. And as any heat wave today, especially in the fast-changing Arctic, hot weather pattern is amplified by climate change. This means that the heat of the event, today is warmer than they have been without human-caused global warming.

In these hot and dry conditions, Siberia is a vast land that is the lead to burn. “You’ve got so much dry material,”said Smith. “It can burn and burn and burn.”
