Research shows that climate change may let global plant large-scale wither

According to foreign media reports, U.S. scientists at the University of Montana recently analyzed records of nearly a decade of plants found by the high concentration of large-scale plant has been the impact of carbon dioxide, dry withered, particularly in the tropics and southern hemisphere regions still is a serious plant .
From the picture below you can see the mainland in recent years of global net primary production of plant conditions. The gray region of which reduce the area of plant production, green plant production area increased. The results showed that the plants on the planet volatile in recent years the amount of carbon dioxide into the atmosphere far more than the amount of carbon dioxide absorbed by plants, the global net primary production of mainland plants significantly reduced.
It is understood that people from 1982 to 1999 had generally believed that continent around the world with high concentrations of carbon dioxide plants can grow under conditions of very strong, but these plants can continue to absorb carbon dioxide. However, the present situation, has been estimated to people is totally the opposite. 80 years in the 19th century, global temperatures began to have the trend of rising, as well as the Earth in the next decade a large number of different areas of emerging drought situation in plants, and plants such as drought, climate change, the situation has led to increasingly more frequently, this drought will continue in the future. Scientists say that global temperatures and dry plants not only results in the net primary production of plants decreased, while the imbalance will result in ecological systems, atmospheric carbon dioxide levels increase, and even the future global food security and biofuel production will therefore be threatened .
