Changing an empty land into forests or reforestation movement was not going to affect the global warming that occurred in this century, says a new study suggests.
The movement is highly recommended reforestation under the Kyoto Protocol of the United Nations (UN) on climate change. Similarly, as quoted by AFP on Monday (6/20/2011).

But researchers environment, in a recent study says that the movement of replanting trees in forests will only reduce the problem of the greenhouse effect. This is because forests take approximately 10 years to grow thick. In addition, carbon dioxide (CO2) is a molecule that durable. These substances are able to be in the atmosphere for centuries.
These results obtained from studies conducted by Vivek Arora from the University of Victoria in British Columbia and Alvaro Montenegro at St. Francis Xavier University in Nova Scotia.

Arora and Montegro predict the movement of the five scenarios of reforestation carried out during the next 50 years, starting from 2011 until 2060. They use a program called CanESM1 mengsimulasikan impact to the land, sea and air, if the Earth's surface temperature rose 3.0 degrees Celsius by 2100, compared to 1850.
"Even if the entire land on Earth has been replanted, then it only reduces the temperature of approximately 0.45 degrees centigrade," said the study published in Nature Geoscience. (okezone)
