The world warms/research:Cold temperate zone forest perhaps turn worse rather tropical rain forest of warming good

For decelerating the world warming, the ordinary people all think and should want various trees, can protect the Earth, however recent has the expert the viewpoint that puts forward entirely different, beautiful method two research of the countries point out, only the tropical rain forest can protect the Earth, the Frigid Zone tree is excessive on the contrary harmful have no benefit.
All think generally, should the variety plant trees a wood to decelerate the speed of the Earth warming, however a report that announce at"the American national science hospital, hospital publish" on 9th points out, planting tree in the Frigid Zone of the ice snow overlay, the result for may producing to afforest with tropical zone entirely different, even turn worse a global warming.
This by the American Lawrence benefit Mo Er national laboratory, the Carnegie institute, and France receive the Pa mile university to cooperate especially of research, the climatology house the exploitation 3 D computer model imitates the positive and negative influence that the different degree of latitude plants a quilt, find in North America, most Europes wait for in the forest of the cold temperate zone region of the high degree of latitude, will obstruct originally should was reflected by the ice snow of sunlight, and cause to heat phenomenon, so the expert predict outcome only in the tropical zone the plant planted, for example tropical rain forest just is everlasting to the permafrost the development has a help most .
The Lawrence benefit Mo Er national laboratory the big machine learn a Ba to pull to say, "our research manifestation, only tropical rain forest just to decelerate the world warming the most helpful."
The report points out planting forest resists the world warming, in addition to wanting to consider tree to be in addition to absorbing the function of the carbon dioxide, also need to consider whether forest contribute to reflecting sunlight or not, increase cloud quantity.Tropical rain forest and have this your benefit, but the cold temperate zone forest meeting absorb the sunlight of the glint by snow ground, letting the temperature rise on the contrary.The research shows that to 2100, The forest of the temperate zone region will make the parts of region temperature ratio have no the temperature increment 10 °F under the condition of forest.
However the report also emphasizes, they isn't the forests that lays claim to chop down Frigid Zone, raising ecosystem after all just is the initial target that obstructs a global warming.Because timber is can reborn energy, compare with the coal mine, petroleum and natural gases to all have a development more, England therefore strengthens to promote the timber fuel, using timber as the warm air and the fuel source, will be able to reduce the depletion of other energies.
Expert's still appealing shouldn't chop down northern forest excessively, because forest in of plant a quilt are diverse sexes to the conservation ecosystem system and the maintenance living creature, still have a tremendous help .
