Xinhua BEIJING, December 25, according to Singapore's "Lianhe Zaobao," 25, U.S. scientists said, terrestrial ecosystems to the annual average temperature of the lower zone to be moved 420 meters in order to adapt to global warming; unable to migrate or transfer speed is too slow, such as plants, as well as the distance required to move the largest species, the higher the probability of extinction.
According to a study released Wednesday shows that due to human emissions of greenhouse gases caused by excessive global warming, the various species of movement and the ability to adapt to new environments will determine whether the species to survive. While the organism itself, the suitable climatic zones farther away, the greater the possibility of their extinction.
The research needs of the distance of movement, saying climate change, bio-facing speed. Study showed that simply moving a small mountain of biological distance, you can get a great temperature changes, and therefore face of climate change on mountain biological slowest; Therefore, the mountain areas will save some species into the next century, particularly plants, because they are does not like animals as rapid response to climate change.
Relatively speaking, the plain areas of the species, the face of climate change would be faster. Mangrove forests or grasslands and other ecological environment in an annual migration distance of more than 420 meters on average more than 1 times.
