Professor Malinowski in the taiga fire: peat swamps are harder to extinguish than forests

The fire in northern Russia is unprecedented. Not only is the taiga burning, but there is also the tundra-a more difficult tundra, Professor of atmospheric physicist. Szymon Malinowski. According to him, there are now no weather conditions to bring dust from the fire to Poland.

There is a big fire in Siberia. According to reports, at the end of July, there were 3 million hectares of forest burning (an area equivalent to Belgium). On August 5, the Russian Ministry of Emergency Affairs said that a quarter of the area had been extinguished by the fire. Due to smog, the air quality in the city has deteriorated significantly. Fires in the Irkutsk and Tyumen regions, Krasnoyarsk, Khabarovsk, Perm and Zabekali regions, Buryatia and Yamalnetsk Autonomous Region All recorded fires.

When asked whether the dust from the Russian fire reached Poland, atmospheric physicist Prof. Szymon Malinowski replied that there are no weather conditions for them to reach our country. He said: “But in Asia and Siberia, this is a problem.”

He said how long the dust will stay in the air, “this is a few weeks after the fire ends.”

Professor’s comments on the situation in Russia. Malinowski said that with climate change, the risk of fires in these areas increases. First, it is relatively dry, which makes the fire spread more easily. Second, thunderstorms are more frequent in these areas, and the risk of fires caused by lightning is greater.

“These are unprecedented fires.” He said: “Not only the taiga fires are important, but the tundra fires-peat swamps are also important. He added that burning peat bogs are more difficult to extinguish than burning forests.

When asked about greenhouse gases (carbon dioxide from fires emitted into the atmosphere), he said that the dust that causes smoke and soot may be a bigger problem. He said: “It will deposit on ice and absorb more solar radiation.” White snow reflects much more solar radiation than dark snow. Therefore, solar energy-instead of leaving the atmosphere-remains in it.

Tree planting campaigns are being carried out all over the world to help combat global warming. At the same time, a large fire in Russia burned an area the size of Belgium. When talking about this issue, Professor Szymon Malinowski assessed that “when the trees grow larger, tree planting will bring results in the next 30-40 years”. Our idea of ​​trees is decades behind. In addition, they will not offset our emissions. If we stop emitting (greenhouse gas-PAP) into the atmosphere at the same time, they will help us”-the scientist concluded.
