Environmentalists have warned about the risk of forest fires in Siberia because of the heat
Established in June in Siberia hot weather increases the risk of forest fires, told RIA Novosti expert ecologists at the University of Stockholm.
With him, also agree associate Professor of the Institute of physical geography, Stockholm University Gustaf Huselius.
"If the weather in Siberia near future will not change, we can expect serious forest fires in this season. If July and August will be rain, the risk is reduced," said Huselius.
The experts do not think the heat wave in Siberia at this time of year is abnormal.
"In Verhojansk has always been a fairly cold winter and moderately warm summer weather, typical for this climate. The average temperature in summer is 17 degrees, the highest up to 25 degrees. With this in mind, the periods of increasing temperature up to 30 degrees and above cannot be regarded as extreme," said Fernstrum.
While scientists agree that global climate change, such hot spells will become more frequent and prolonged, which entails a number of risks.
"The consequence of high temperatures is something that is beginning to thin permafrost layer. When the ice lying at the base of the soil begins to melt, there is a risk of education failure. It can affect infrastructure such as buildings, roads, oil and gas pipelines and so on, which can be destroyed when the soil starts to sink," - said RIA Novosti Dr. Britta Sandel, senior lecturer in the Department of physical geography, Stockholm University.
According to experts, by 2050 the permafrost will become thinner so that it will cover 70% of the infrastructure in the region.
Another negative effect of melting permafrost may be released into the atmosphere large amounts of greenhouse gases: carbon dioxide and methane. This is because permafrost contains a large number of not fully decomposed remains of plants and therefore organic carbon. While the ground is frozen, the coal remains in it. But when the permafrost layer begins to thin, the atmosphere begins to stand large amounts of greenhouse gases - carbon dioxide and methane.
By the end of this century, permafrost will highlight the atmosphere of the order of 3-4 billion tons of CO2 per year, which is about as much as today, allocates the whole of the EU, experts say.
