Huge swathes of the Arctic are ablaze - here's why

Wildfires are ravaging the Arctic, with areas of northern Siberia, northern Scandinavia, Alaska and Greenland engulfed in flames.

Lightning frequently triggers fires in the region but this year they have been worsened by summer temperatures that are higher than average because of climate change.

Plumes of smoke from the fires can be seen from space.

Mark Parrington, a wildfires expert at the Copernicus Atmosphere Monitoring Service (Cams), described them as "unprecedented".

How bad is it?
There are hundreds of fires covering mostly uninhabited regions across eastern Russia, northern Scandinavia, Greenland and Alaska.



But smoke is affecting wider surrounding areas, engulfing some places completely.

Cities in eastern Russia have noted a significant decrease in air quality since the fires started.

1.5M hectares of Siberian forests are burning! Smog has reached villages and cities! Catastrophe has already happened! What should happen for the Government to take an action?

The smoke has reportedly reached Russia's Tyumen region in western Siberia, six time zones away from the fires on the east coast.

In June, the fires released an estimated 50 megatonnes of carbon dioxide - the equivalent of Sweden's annual carbon output, according to Cams.


How unusual is this?
Arctic fires are common between May and October and wildfires are a natural part of an ecosystem, offering some benefits for the environment, according to the Alaska Centers website.

But the intensity of these fires, as well as the large area they have taken up, make these unusual.



"It is unusual to see fires of this scale and duration at such high latitudes in June," said Mr Parrington.

"But temperatures in the Arctic have been increasing at a much faster rate than the global average, and warmer conditions encourage fires to grow and persist once they have been ignited."

Extremely dry ground and hotter than average temperatures, combined with heat lightning and strong winds, have caused the fires to spread aggressively.

The burning has been sustained by the forest ground, which consists of exposed, thawed, dried peat - a substance with high carbon content.

Dangerous amplification

Global satellites are now tracking a swathe of new and ongoing wildfires within the Arctic Circle. The conditions were laid in June, the hottest June for the planet yet observed in the instrumented era.

The fires are releasing copious volumes of previously stored carbon dioxide and methane - carbon stocks that have in some cases been held in the ground for thousands of years.

Scientists say what we're seeing is evidence of the kind of feedbacks we should expect in a warmer world, where increased concentrations of greenhouse gases drive more warming, which then begets the conditions that release yet more carbon into the atmosphere.

A lot of the particulate matter from these fires will eventually come to settle on ice surfaces further north, darkening them and thus accelerating melting.

It's all part of a process of amplification.

What is being done to tackle the fires?
Russian authorities are not tackling the majority of the fires as they argue the cost would be bigger than the damage caused by the flames.

"They do not threaten any settlements or the economy," the press service of the Krasnoyarsk Region forestry ministry told a Siberian news website.

The hashtags #putouttheSiberianfires and #saveSiberianforests are currently trending on Twitter as Russians complain the government is not doing enough to tackle the crisis.

Some argue that the Notre Dame fire in Paris received far more media attention than the forest fires.

"Remember how far the news about the Notre Dame fire spread? Now is the time to do the same about the Siberian forest fires," said one tweet.

Another said: "Let's not forget that nature is no less important than history. Numerous animals have lost their homes, and many of them are probably dead. Just thinking about this is painful."

Alaska Centers agree that "fire-suppression efforts sometimes are more damaging than the wildfire".

So Much of the Arctic Is on Fire, You Can See It From Space
By Laura Geggel, Associate Editor | July 25, 2019 06:51am ET


Wildfires burning large swaths of Russia are generating so much smoke, they're visible from space, new images from NASA's Earth Observatory reveal.

Since June, more than 100 wildfires have raged across the Arctic, which is especially dry and hot this summer. In Russia alone, wildfires are burning in 11 of the country's 49 regions, meaning that even in fire-free areas, people are choking on smoke that is blowing across the country.

The largest fires — blazes likely ignited by lightning — are located in the regions of Irkutsk, Krasnoyarsk and Buryatia, according to the Earth Observatory. These conflagrations have burned 320 square miles (829 square kilometers), 150 square miles (388 square km) and 41 square miles (106 square km) in these regions, respectively, as of July 22.

The above natural-color image, taken on July 21, shows plumes rising from fires on the right side of the photo. Winds carry the smoke toward the southwest, where it mixes with a storm system. The image was captured with the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP, a weather satellite operated by the U.S. National Oceanic and Atmospheric Administration.

The Russian city of Krasnoyarsk is under a layer of haze, the Earth Observatory reported. And while Novosibirsk, Siberia's largest city, doesn't have any fires as of now, smoke carried there by the winds caused the city's air quality to plummet.

Wildfires are also burning in Greenland and parts of Alaska, following what was the hottest June in recorded history. It's common for fires to burn during the Arctic's summer months, but the number and extent this year are "unusual and unprecedented," Mark Parrington, a senior scientist at the Copernicus Atmosphere Monitoring Service (CAMS), a part of the European Union's Earth observation program, told CNN.

These fires are taking a toll on the atmosphere; they've released about 100 megatons of carbon dioxide from June 1 to July 21, which is roughly equivalent to the amount of carbon dioxide Belgium released in 2017, according to CAMS, CNN reported.

The Arctic is heating up faster than other parts of the world, making it easier for fires to thrive there. In Siberia, for example, the average June temperature this year is nearly 10 degrees Fahrenheit (5.5 degrees Celsius) hotter than the long-term average between 1981 and 2010, Claudia Volosciuk, a scientist with the World Meteorological Organization, told CNN.

Many of this summer's fires are burning farther north than usual, and some appear to be burning in peat soils, rather than in forests, Thomas Smith, an assistant professor of environmental geography at the London School of Economics, told USA Today. This is a dangerous situation, because whereas forests might typically burn for a few hours, peat soils can blaze for days or even months, Smith said.

Moreover, peat soils are known carbon reservoirs. As they burn, they release carbon, "which will further exacerbate greenhouse warming, leading to more fires," Smith said.
