Scientists worry because weed is growing in the Arctic
Scientists have recently alerted the warning that the Arctic green cover is becoming increasingly complex.
Contrary to other well-developed plants is a good sign, in the Arctic this means negative consequences not only for this place but also for the whole world.

A team of 40 scientists from 36 universities and environmental organizations has carried out research on Arctic green cover over the years. Through satellite images and from helicopter marked over time, the team found that plants have grown more with about 1.5 times the rate.
Even some of the everlasting glaciers that were formerly absent from plants have appeared the color of weed. Dr Isla Myers Smith - School of Geosciences, University of Edinburgh, author of the study - said: "On satellite images, it is possible to see some weeds in areas that have not been seen before . "

The Wired noted that the presence of green in the Arctic is a sign that the land is increasingly affected by climate change . According to scientists, the Arctic is warming at a rate twice as fast as other regions of the Earth.
Rapid melting of ice has created bare patches of land, while providing fresh water for the growing weeds.
Despite its reputation for being cold and icy, the Arctic is not as barren as Antarctica but still has life, especially in the melting seasons.
Weed roots are often deep in the rock beneath the snow, waiting until the warm season of the year will develop and continue the cycle of the next year. According to the team, the Arctic weed roots are also noted to be longer and deeper to the soil layers than before.

Weeds have been one of the main contributors to the number of record fires here for more than half a century, recorded in 2019.
The changes in the vegetation here also change the way carbon is absorbed and released into the atmosphere, in addition to raising concerns that herbivores will gradually move to this polar region.
Some extreme events have become more frequent due to warmer Arctic weather, for example, thunder has gradually become common in many areas here. The new study is published in Nature Climate Change .

Previously, in 2013, the American Museum of Natural History also made a prediction map of the plants, grasses, and bushes that can live in many parts of the Arctic.
The team forecasts there will be a large area here covered with trees from now until 2050, mainly in some areas of the southern Arctic in the territory of Canada, Russia and the US state of Alaska.
The group also said that by 2050, the plant array will grow north by 20 latitudes with an increase of 52% in the area. Besides, from 48-69% of plants will evolve new varieties.
