They could be perpetrators because the soil in the region, has the potential to emit massive quantities of greenhouse gases in the future and they could be saviors because the trees and bushes store large amounts of the gas emitted in the burning of fossil fuels in their branches, needles and trunks.
According to rough estimates, only about half of the carbon dioxide produced by human activity accumulates in the atmosphere. The biosphere and oceans absorb the other half. In other words, a large share of the carbon coming from European smokestacks and car exhausts ends up in the trunks of Siberian coniferous trees. Humans and animals adaptation to Taiga Animals of the taiga, such as foxes or bears, have always been hunted. Their warm fur and tough skin, turned into leather, have helped people survive in harsh climates for thousands of years.
For Example: "The Brown Bear has adapted by having a thick coat of fur. The thick coat of fur, allows it to stay warm in the cold climate. It also has big claws to allow it to climb trees. This allows it to climb trees and reach food.The bear has also has adapted by hibernating, this allows it to not search for food in the winter, this can occur, because the bears eat enough to survive through winter."
Plants have learned how to adapt to the harsh environment, by growing closer to each other allowing for more warmth.
For long periods of time, the Sami lifestyle thrived because of its adaptation to the Arctic environment. The Sami people are one of the largest indigenous groups in the whole of Europe! They are adapted to their surroundings in many different ways, they fish on the coast (and inland), trap & kill animals for their fur and sheep and reindeer herding. The clothing of the Sami people is some what unusual. They where brightly color clothes with a special hat and shoes or boots. This Sami uniform is used for mainly reindeer herding. Nowadays, most Sami people live a normal modern life with cars and houses. Only about 5% of Samis herd reindeer now. Taiga ecosystems are threatened by direct human activity and climate change.
Civilization is dependent on sturdy buildings for homes, industry, and schools. The trees of the taiga are cut down for lumber projects, as well as paper, cardboard, and other supplies. The export of wood and paper products is one of the most economically important industries in Taiga.
Clearcutting is the most popular type of logging in taigas. Clearcutting involves cutting down all the trees in a designated area. This destroys habitats for many organisms that live in and around the trees, and makes it difficult for new trees to grow. Clearcutting also increases the risk of erosion and flooding in the taiga. Without a root system to anchor it, a taiga’s soil can be blown away by wind or worn away by rain or snow. This exposes the bedrock and permafrost beneath the taiga, which does not support many forms of life.
Climate change puts taigas in danger in different ways. Warming climate contributes to a partial thawing of the permafrost. Since this water has no place to drain, more area of the taiga is taken over by muskegs. Few trees take root. Man-Made Fires and Deforestation
These local fires, usually ignited by lightning, offer nature an opportunity to rejuvenate.
Using satellite images, the Max Planck researchers have calculated that 87 percent of all forest fires in the region are caused by human activity.
The Russian practice is to completely "harvest" an area covering many square kilometers. Using large tracked vehicles, they plow across the frozen ground in the winter. If a fire devastates the young tree plants in the summer, the field threatens to turn into grassland.
If the forests were cut down for lumber, this would not affect Russia's carbon dioxide balance, at least not officially. But it would be more detrimental to the climate than the emissions from hundreds of coal-fired power plants. In addition to releasing the carbon dioxide stored in the trees, logging, by destroying the forests, would eliminate their value as a collector of greenhouse gases. Warming temperature also changes animal habitats. It pushes native species out and attracts non-native species. Animals such as the Siberian tiger are not adapted to warm weather. Its coat is too heavy, and it stores too much body fat to thrive in a temperate habitat. Non-native insects such as the bark beetle can infest trees such as spruce. Millions of these insects bore into the bark of trees, laying eggs. The infested trees die. Bark beetle infestations can kill entire forests and thousands of hectares of taiga.
The Taiga is being destroyed everyday by both humans and nature. Nature causes forest fires with lighting, diseased by parasites or herbicides, and spruce trees that grow on top thick moss are frequently blown over by strong winds. Large-scale clear cutting, plantation forestry, introduction of exotic tree species, soil sacrification, ditching, and use of pesticides or herbicides have led to habitat loss. Large-scale industrial forestry, or logging, is the greatest important threat effecting the boreal forest. The wood is used in the "pulp factory" for pulp and paper. Other threats to the Taiga are oil and gas exploration, road building, mining, human triggered forest fire, and climate change. Animals of the Taiga are being hunted and trapped for their fur which decreases their population greatly. Hydroelectric power has ruined the water system. Many fish have mercury poisoning. The Taiga is being destroyed equal to that of the rainforest. Coriolis Effect Polar Easterlies: At about the latitude of Norway and northward (60-90 degrees) the Polar easterlies blow irregularly from the east and north.
Polar Front: Between the polar easterlies and the westerlies is the polar front.
Westerlies: At about the latitude of Russian taiga (30-60 degrees) the Westerlies blow from the west, tending somewhat toward the north. This causes most weather to move from west to east. Influence of the Tundra to the Taiga Cold arctic air comes from the tundra to the taiga and lowering the temperature in the taiga. Taiga and Tundra A BAROMETER is a scientific instrument used in meteorology to measure atmospheric pressure. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems, and frontal boundaries. A RAIN GAUGE measures the amount of rain that has fallen over a specific time period. WEATHER SATELLITES are used to photograph and track large-scale air movements. Then meteorologists compile and analyze the data with the help of computers.
